The Nurse, Professional Practice and Scope
In a few months you will walk into a room, put your hands on a stranger, and decide whether what you are seeing is normal. Everything that follows in this book — every technique, every number, every red flag — rests on a license that is granted by a state, defined by a statute, and revocable. This chapter is about that foundation. It explains what a nursing license actually authorizes, where the boundary of your scope sits and how to test whether an action falls inside it, what you may hand to an assistant and what never leaves you, and how the standards of practice, the Code of Ethics and the law of negligence converge at the bedside. It ends where every chapter in this book ends: with the findings that mean stop, escalate now, and the exact words — SBAR — you will use to escalate them.
By the end of this chapter you can
- Distinguish the legal authority and educational preparation of the CNA, LPN/LVN, RN and APRN, and explain what the NCLEX-RN and the Nurse Licensure Compact do.
- Locate your Nurse Practice Act and apply a three-question scope of practice test before performing any unfamiliar task.
- Apply the five rights of delegation and correctly sort tasks into what may go to UAP, what may go to an LPN/LVN, and what must stay with the RN.
- Name the six ANA Standards of Practice and the four elements of negligence, and describe the nurse’s specific role in informed consent and in restraint use.
- Perform and sequence the four assessment techniques — inspection, palpation, percussion, auscultation — and state the abdominal exception and why it exists.
- State adult vital-sign ranges to the exact number and adjust expected values for infants, children, pregnancy and older adults.
- Assess for cyanosis, jaundice, pallor and erythema in patients of any skin tone using oral mucosa, conjunctivae, sclerae and palms/soles.
- Rewrite a vague chart entry as a precise, defensible one, and correct a documentation error legally.
- Recognize adult and pediatric red flags that require escalation now, and deliver a complete SBAR report up the chain of command.
Section 1Becoming and Staying a Nurse
The credentials, and what each one legally means
Students use the word “nurse” loosely; the law does not. A certified nursing assistant (CNA) holds a certification, not a license, after roughly four to sixteen weeks of training. A CNA is authorized to provide personal care and to collect certain routine data. A licensed practical nurse or licensed vocational nurse (LPN/LVN) completes a twelve- to eighteen-month program and passes the NCLEX-PN. An LPN holds a license and a defined, narrower scope: in most states an LPN may administer most medications, perform sterile dressing changes and tracheostomy care, insert a urinary catheter, and gather data — but works under the direction of an RN or a provider and does not perform the initial comprehensive assessment or independently formulate the plan of care.
The registered nurse (RN) comes from one of three routes: a diploma program, an associate degree in nursing (ADN/ASN), or a bachelor of science in nursing (BSN). All three sit for the same examination, the NCLEX-RN, and all three receive the same license with the same legal scope. The degrees are not legally different; they are professionally different. The BSN adds community health, leadership, research literacy and statistics, and it is the entry point for graduate study and for Magnet-designated employers. An advanced practice registered nurse (APRN) — nurse practitioner, clinical nurse specialist, certified registered nurse anesthetist, or certified nurse-midwife — holds a graduate degree, national certification, and a second, separate state authorization that permits diagnosis and, in most states, prescribing.
| Credential | Preparation | Examination | What it authorizes |
|---|---|---|---|
| CNA / UAP / PCT | Weeks to a few months; state registry | State competency exam (certification, not licensure) | Hygiene, feeding, ambulation, positioning, intake and output, weights, and routine vital signs on stable patients — all delegated by an RN |
| LPN / LVN | 12–18 months, practical nursing program | NCLEX-PN | Data collection, most medication administration, sterile procedures, wound and ostomy care, reinforcement of teaching — under RN or provider direction |
| RN (ADN, diploma or BSN) | 2–4 years | NCLEX-RN | Comprehensive assessment, nursing diagnosis, planning, implementation, evaluation, patient teaching, delegation and supervision |
| APRN (NP, CNS, CRNA, CNM) | Master’s or doctoral degree plus national certification | NCLEX-RN plus certification exam | Advanced assessment, diagnosis, ordering and interpreting tests, and prescribing (scope varies by state: full, reduced or restricted practice) |
The Nurse Practice Act and your board of nursing
Every state and territory has a Nurse Practice Act (NPA) — an actual statute passed by that state’s legislature. The NPA defines who may call themselves a nurse, what nursing practice includes, the grounds for discipline, and it creates the board of nursing (BON), the agency that issues your license and can suspend or revoke it. The BON then writes administrative rules and advisory opinions that fill in the detail the statute leaves open. This is the single most important document in your professional life and most students never read it. Read yours before you start clinicals. It is free, it is online, and it is written in plain enough English.
The National Council of State Boards of Nursing (NCSBN) is the organization the boards jointly own; it develops the NCLEX and administers the Nurse Licensure Compact (NLC). A multistate license issued by a compact state lets you practice, physically or by telehealth, in every other compact state without a second license. It does not exempt you from the practice act of the state where the patient is located — the rule is that you practice under the law of the state where the patient is, not where you are sitting. Licenses are renewed on a state-set cycle, usually every two years, generally with continuing education and sometimes practice-hour requirements.
Discipline is real and it is public. The most common paths to a board action are diversion of controlled substances, practicing while impaired, falsification of documentation, patient abandonment (leaving an assignment without transferring care to a qualified person), boundary violations, and practicing outside scope. Most states also make you a mandatory reporter of suspected abuse or neglect of a child, an older adult, or a dependent adult — a duty that belongs to you personally and is not discharged by telling the charge nurse and letting it go.
What professional practice actually asks of you
Licensure is the floor. The profession expects more, and the framework most schools use is QSEN — Quality and Safety Education for Nurses — with six competencies: patient-centered care, teamwork and collaboration, evidence-based practice, quality improvement, safety, and informatics. These are not slogans. Patient-centered care means the plan is built around what the patient values, not around what is convenient for the unit. Evidence-based practice means that when you were taught something in 2018 and the evidence changed in 2024, you change. Informatics means you can find the answer in the chart and in the literature quickly, and that you understand the electronic record is a legal document and a data source, not a typing chore.
Professional practice also means accountability that does not transfer. You are accountable for the assessment you performed, the medication you pushed, the finding you did or did not report, and the task you delegated. “The provider ordered it” is not a defense if the order was clearly unsafe — a nurse who administers an obviously wrong dose shares liability with the prescriber. The correct action when an order looks wrong is to hold it, clarify it with the prescriber, and document the clarification.
Your authority to practice comes from a state statute, the Nurse Practice Act, enforced by a board of nursing — not from your employer, your degree or your job description.
Section 2Scope, Delegation and the Team
Three questions before you do anything unfamiliar
New nurses get into trouble not by doing something malicious but by doing something helpful that was not theirs to do. Before you perform a task you have not performed before, run three questions in order. One: is it within my state’s Nurse Practice Act and board rules? If the statute or the board says no, stop — nothing downstream can rescue it. Two: is it within my employer’s policy, and do I have an order or protocol if one is required? Facilities lawfully restrict practice below the statutory ceiling; a hospital may decide RNs do not push a given medication even where the state permits it. Three: am I personally competent — educated, trained, and validated — to do this safely right now? A yes to the first two and a no to the third still means you do not do it; you find someone who can and you arrange to be taught.
The most common scope traps in the first year are administering an IV push medication in a facility that does not credential RNs for it, titrating a drip without a protocol, taking a verbal order in a non-emergency situation when policy forbids it, performing a skill you watched but were never checked off on, and “just” suturing, casting, or adjusting a device because a provider asked and was busy. In every one of these, the safe answer is the same sentence: “I’m not checked off on that — I’ll get someone who is.” No one has ever been disciplined for saying it.
Who may do what
Two words get confused constantly. Assignment is transferring both the responsibility and the accountability for tasks that are already within the receiving person’s own scope and job description — a charge nurse assigning four patients to an RN. Delegation is transferring responsibility for performing a specific task to someone whose scope does not otherwise include it, while you keep the accountability. If a UAP takes a blood pressure you delegated and it is wrong, the number is your problem. Supervision is the ongoing monitoring that follows delegation; you cannot delegate and then disappear.
| Task | UAP / CNA | LPN / LVN | RN only |
|---|---|---|---|
| Vital signs on a stable patient | Yes (RN interprets) | Yes | — |
| Vital signs on an unstable or newly admitted patient | No | No if the patient is unstable; on a stable new admission an LPN may collect data under RN direction | Yes — RN performs and interprets |
| Bathing, feeding, oral care, positioning, ambulation of a stable patient | Yes | Yes | — |
| Intake and output, daily weight, specimen collection, point-of-care glucose (state-dependent) | Yes | Yes | — |
| Oral, subcutaneous and intramuscular medications | No | Yes (most states) | Yes |
| Sterile dressing change, tracheostomy care, urinary catheter insertion, enteral feeding | No | Yes | Yes |
| IV push medication, blood product administration, central line care, titrating drips | No | No (rare state exceptions) | Yes |
| Initial and ongoing assessment, nursing diagnosis, care planning | No | No — may collect data only | Yes |
| Patient and family teaching, discharge education | No | May reinforce teaching already given | Yes — initial teaching |
| Evaluation of the response to an intervention | No | No | Yes |
| Any care of an unstable or unpredictable patient | No | No | Yes |
The five rights of delegation
NCSBN and the ANA describe five checks, and they are worth memorizing because NCLEX tests them relentlessly. Right task — it is repetitive, predictable, low-risk, and does not require nursing judgment. Right circumstance — this patient is stable and the setting is appropriate; the same task on a different patient may not be delegable. Right person — this specific individual has the training and demonstrated competence, not merely the job title. Right direction and communication — you state the task, the patient, the expected method, the deadline, and exactly what to report back and when. Right supervision and evaluation — you follow up, you obtain the result, and you evaluate the outcome yourself.
Vague delegation is unsafe delegation. Compare “Can you get vitals on room 12?” with “Please take a manual blood pressure on Mr. Ruiz in 12 within the next ten minutes, sitting, left arm, and tell me the number right away if the systolic is under 100 or over 160.” The second sentence gives the task, the patient, the method, the timeframe and the reporting threshold. It takes eight seconds longer and it is the difference between delegation and hoping.
Four things never leave the RN, and this is the sentence to carry into the exam and into practice: assessment, nursing diagnosis and planning, teaching, and evaluation — plus anything at all involving an unstable patient. A UAP may gather a number; only the RN decides what that number means. If a UAP reports a blood pressure of 86/50, the delegated task was completed correctly and the clinical problem is entirely yours.
You may delegate a task but never the accountability for it, and assessment, teaching, evaluation and unstable patients never leave the registered nurse.
Section 3Standards, Ethics and the Law at the Bedside
The standards you will be measured against
When a case is reviewed, the question is not whether you meant well — it is whether you met the standard of care, defined as what a reasonably prudent nurse with similar preparation would have done in similar circumstances. That standard is built from the ANA Nursing: Scope and Standards of Practice, your state’s NPA, facility policy, manufacturer instructions, and current evidence. The six Standards of Practice map exactly onto the nursing process and are the spine of the next chapter: assessment, diagnosis, outcomes identification, planning, implementation and evaluation. Layered on top are the Standards of Professional Performance — ethics, advocacy, respectful and equitable practice, communication, collaboration, leadership, education, scholarly inquiry, quality of practice, professional practice evaluation, resource stewardship and environmental health.
Standards are not aspirational language. If a patient falls and the record shows no fall-risk screening was documented on admission, the deviation from the assessment standard is the case. This is why documentation is not clerical work: in a legal review, care that was not documented is treated as care that was not given.
Ethical principles and the Code of Ethics
The ANA Code of Ethics for Nurses is the profession’s non-negotiable statement of obligation. Its provisions establish that the nurse practices with compassion and respect for every person, that the nurse’s primary commitment is to the patient, that the nurse advocates for and protects the patient’s rights and safety, and that the nurse owes the same duties to self as to others — a provision that matters when you are asked to take a ninth patient or a third consecutive double shift.
| Principle | What it obligates | At the bedside |
|---|---|---|
| Autonomy | Respect the patient’s right to decide | A competent adult may refuse a medication you are certain they need; you document the refusal and notify the provider |
| Beneficence | Act for the patient’s good | Repositioning a patient at 0200 because pressure injuries form in hours |
| Nonmaleficence | Do no harm | Holding a beta blocker when the apical pulse is 48 and calling the prescriber |
| Justice | Distribute care fairly | The uninsured patient receives the same pain assessment and the same response as everyone else |
| Fidelity | Keep your promises | You said you would return in twenty minutes with the pain medication — you return in twenty minutes |
| Veracity | Tell the truth | You do not tell a patient “this won’t hurt” when it will; you do not chart what you did not do |
The legal floor: negligence, consent, privacy and restraints
Negligence is failing to act as a reasonably prudent person would; malpractice is professional negligence. A plaintiff must prove four elements, all of them: duty (you had a nurse–patient relationship), breach (you departed from the standard of care), causation (that breach caused the harm), and damages (real injury occurred). Missing one element ends the case. Also know the intentional torts, because they are quieter and easier to commit: assault (threatening unwanted contact — “hold still or I will hold you down”), battery (the contact itself, including performing a procedure a patient refused), false imprisonment (restraining or confining without order or emergency justification), defamation (libel in writing, slander in speech), and invasion of privacy.
Informed consent belongs to the person performing the procedure. The provider must explain the diagnosis, the nature and purpose of the procedure, the risks and benefits, the alternatives, and the consequences of refusing. The nurse’s role is narrow and specific: verify that the consent form is signed, that the signature is voluntary, and that the patient can describe in their own words what is about to happen — then witness the signature. If the patient says “they’re taking out my gallbladder, I think, or maybe part of my colon,” you stop, you do not have them sign, and you page the provider. Consent obtained after a sedating premedication is not valid consent.
HIPAA protects health information; the rule of practice is minimum necessary and need-to-know. The most frequent violations by students are elevator and hallway conversations, looking up a patient you are not assigned to, and photographing anything on a personal phone. Restraints are a last resort, never a response to short staffing, convenience or punishment, and are used only after less restrictive alternatives have been tried and documented. They require a provider order that is never written as needed (no PRN restraint orders) and that is time-limited: for violent or self-destructive behavior, up to 4 hours for an adult, 2 hours for ages 9–17, and 1 hour for children under 9, with a face-to-face evaluation of the patient by a physician or trained licensed independent practitioner within 1 hour of initiation. Use the least restrictive effective type, and monitor frequently with release, repositioning, range of motion, fluids, toileting, circulation and skin checks. Applying restraints without an order, outside an immediate emergency, is false imprisonment.
You are judged against the standard of care — what a reasonably prudent nurse would have done — and the record of what you assessed, reported and documented is the evidence of whether you met it.
Section 4The Core Skill: Assessing, Measuring, Documenting
The four techniques and the order they go in
Every regional examination in this textbook uses the same four techniques in the same order. Inspection comes first and is the most underused: you look, deliberately and with adequate light, comparing side to side, before you touch anything. Inspect for color, symmetry, contour, movement, lesions, drainage and effort. Most abnormal findings are visible before they are palpable. Palpation comes second. Use the finger pads for texture, pulses, moisture, tenderness and masses; the ulnar or palmar surface for vibration such as thrills and fremitus; and the dorsum of the hand for temperature, because it is more sensitive to heat. Light palpation depresses about 1 cm; deep palpation depresses about 4–5 cm and is used to identify organs and deep masses. Palpate tender areas last, and warm your hands.
Percussion comes third. Press the distal phalanx of the non-dominant middle finger firmly on the skin, keep the other fingers off the surface, and strike that phalanx sharply with the tip of the dominant middle finger using wrist motion only, withdrawing immediately. You are listening for whether the tissue underneath is air-filled, fluid-filled or solid: resonance over normal lung, hyperresonance over trapped air as in emphysema or pneumothorax, tympany over the gastric bubble and the intestines, dullness over the liver, a full bladder or consolidated lung, and flatness over bone and muscle. Auscultation comes fourth. Use the diaphragm pressed firmly for high-pitched sounds — breath sounds, bowel sounds, normal heart sounds S1 and S2 — and the bell held lightly for low-pitched sounds such as S3, S4, and bruits. Place the stethoscope on skin, never over a gown, and stop moving and talking while you listen.
There is one exception, and it is the abdomen. The abdominal sequence is inspect, auscultate, percuss, palpate. Auscultation is moved ahead of percussion and palpation because pressing on the abdomen mechanically stimulates or suppresses peristalsis and changes the bowel sounds you are about to grade. If you palpate first, the bowel sounds you then document are an artifact you created. Auscultate all four quadrants, beginning in the right lower quadrant near the ileocecal valve where sounds are usually most active; normal is 5–30 gurgles per minute, and before you may document absent bowel sounds you must listen for a full 5 minutes in that quadrant. Sequence errors like this one are exactly the kind of mistake that looks trivial on paper and produces a false finding in a real chart.
The numbers you must know cold
You cannot recognize abnormal until normal is automatic. These are adult values; commit them to memory now, because during a rapid response nobody will let you look them up.
| Measure | Expected adult value | Abnormal | What the abnormal finding suggests |
|---|---|---|---|
| Temperature (oral) | 36.5–37.5 °C (97.7–99.5 °F); mean 37.0 °C (98.6 °F) | Fever ≥ 38.0 °C (100.4 °F); hypothermia < 35.0 °C (95.0 °F) | Infection, inflammation, drug reaction; hypothermia in sepsis, exposure, hypothyroidism |
| Temperature by route | Rectal about 0.5 °C (0.9 °F) above oral; axillary about 0.5 °C below oral; tympanic and temporal approximate core | Route not documented | Comparing an axillary reading to a rectal one creates false trends — always chart the route |
| Pulse (apical or radial, full 60 s if irregular) | 60–100 beats/min, regular | Bradycardia < 60; tachycardia > 100; irregular rhythm; pulse deficit | Bradycardia: beta blockers, digoxin toxicity, heart block. Tachycardia: pain, fever, hypovolemia, hypoxia, anxiety |
| Respirations (count 30–60 s, unobserved) | 12–20 breaths/min, quiet, effortless, regular | < 12 or > 20; accessory muscle use; nasal flaring; retractions | Bradypnea: opioids, rising intracranial pressure. Tachypnea: hypoxia, acidosis, pain, anxiety, pulmonary embolism |
| Blood pressure | Less than 120/80 mm Hg; pulse pressure 30–40 mm Hg; mean arterial pressure at least 65 mm Hg (systolic plus twice diastolic, divided by three) | Elevated 120–129 / under 80; stage 1 130–139 or 80–89; stage 2 at or above 140 or 90; crisis above 180 and/or above 120; hypotension below 90 systolic | Cuff bladder width about 40% of arm circumference and length about 80%; a cuff too small or wrapped too loosely falsely raises the reading and one too large falsely lowers it. Feet flat, back supported, arm at heart level, no talking, five minutes seated. Hypotension with tachycardia suggests hypovolemia or sepsis |
| Orthostatic vitals | Minimal change on standing | Systolic drop ≥ 20 mm Hg or diastolic drop ≥ 10 mm Hg within 3 minutes of standing, or a rise in pulse ≥ 20 | Volume depletion, bleeding, antihypertensives, autonomic dysfunction — high fall risk |
| Oxygen saturation | 95–100% on room air | Below 95%; below 90% is hypoxemia (roughly PaO2 60 mm Hg) | In chronic CO2 retention the target is commonly 88–92% — verify the ordered target before titrating oxygen |
| Pain | Self-report on a 0–10 numeric scale, assessed with every vital-sign set (the older label “fifth vital sign” has been retired, because a score alone is not an order for an opioid) | Any score above the patient’s stated goal | Nonverbal patients require a behavioral tool such as FLACC or PAINAD — never assume no report means no pain |
| Urine output | At least 30 mL/hour, or 0.5 mL/kg/hour | Less than 30 mL/hour for 2 consecutive hours | Hypovolemia, hypoperfusion, acute kidney injury, obstruction |
Values shift across the lifespan, and the shift is largest at the extremes. Children run faster and breathe faster; older adults run cooler and stiffer. Memorize the direction of change even if you keep the table handy.
| Age | Heart rate (beats/min) | Respirations (breaths/min) | Blood pressure (mm Hg) |
|---|---|---|---|
| Newborn (0–1 month) | 100–160 | 30–60 | About 60–90 systolic |
| Infant (1–12 months) | 100–160 | 30–53 | 72–104 / 37–56 |
| Toddler (1–3 years) | 90–150 | 22–37 | 86–106 / 42–63 |
| Preschool (3–5 years) | 80–140 | 20–28 | 89–112 / 46–72 |
| School age (6–12 years) | 70–120 | 18–25 | 97–115 / 57–76 |
| Adolescent (13–18 years) | 60–100 | 12–20 | 110–131 / 64–83 |
| Adult | 60–100 | 12–20 | Less than 120/80 |
| Older adult (65 and above) | 60–100 (less rate reserve; blunted response to stress) | 12–20 (reduced chest wall compliance) | Rising systolic and widening pulse pressure; isolated systolic hypertension is common but not “normal aging” |
Three lifespan cautions save lives. First, in infants and children hypotension is a late and ominous sign — children compensate with tachycardia and vasoconstriction until they crash; for ages 1–10 years, hypotension is a systolic below 70 plus twice the age in years. Second, in older adults the febrile response is blunted: a temperature of 37.8 °C (100.0 °F), or a rise of 1.1 °C (2 °F) above that person’s own baseline, is a significant fever, and new confusion may be the only sign of infection. Third, in pregnancy heart rate rises 10–20 beats/min, blood volume rises 30–50%, and blood pressure falls slightly through the second trimester before returning to baseline by term; after about 20 weeks, lay the patient in a left lateral tilt rather than supine, because the gravid uterus compresses the inferior vena cava and drops cardiac output.
Seeing findings on every skin tone
Much of the classic physical-examination vocabulary was written for pale skin, and describing findings only as “redness” or “blueness” causes real, documented harm — pulse oximeters overestimate saturation in patients with darker skin, and stage 1 pressure injuries are missed at higher rates. The fix is technique, not vocabulary: assess the areas with the least melanin and the thinnest tissue, use natural or bright white light, compare with the patient’s own unaffected skin, and palpate as well as look.
| Finding | In lighter skin | In darker skin | Where to look and what to do |
|---|---|---|---|
| Cyanosis | Blue-gray lips, nail beds, skin | Ashen or dull gray mucous membranes; loss of the normal red undertone | Oral mucosa, tongue, conjunctivae, palms, soles, nail beds — and check the oxygen saturation and work of breathing rather than trusting color alone |
| Jaundice | Yellow skin and sclerae | Yellow-brown sclerae and hard palate; skin change may be inapparent | Sclera close to the iris (peripheral scleral fat can look normally yellow), hard palate, palms and soles |
| Pallor | Loss of pink; waxy or white | Ashen-gray or yellow-brown skin; dull appearance | Conjunctivae, oral mucosa, nail beds, palms — pale conjunctivae suggest anemia in any skin tone |
| Erythema / inflammation | Redness with warmth | Deeper, violaceous, purple or darker-than-surrounding hue; redness may be invisible | Palpate for warmth, firmness, bogginess, induration and tenderness; compare to the mirror-image site on the other side |
| Stage 1 pressure injury | Nonblanchable redness over a bony prominence | Color change may be subtle or absent | Temperature change, firm or boggy texture, and pain over the prominence are the reliable signs; document the technique used |
| Petechiae | Tiny red-purple nonblanching dots | Best seen on lighter-pigmented surfaces | Buccal mucosa, conjunctivae, abdomen, volar forearm |
Charting it so it holds up
Documentation is a clinical intervention and a legal record simultaneously. Chart what you observed and measured, not what you concluded without data; quote the patient in their own words; time everything; and never leave a blank space that another person could fill in. Chart after care, never before. Enter a late entry as a late entry with both the current time and the time the event occurred. In an electronic record, use the amendment function — the audit trail preserves the original anyway, and an attempt to conceal reads far worse in court than the error did.
| Vague entry | Precise entry | Why the difference matters |
|---|---|---|
| “Pt had a rough night. VS stable. Will monitor.” | “0300 — Patient awake, restless, repositioning frequently. Reports sharp RLQ pain 8/10 on 0–10 numeric scale, up from 4/10 at 2200. T 38.4 °C oral, HR 118 regular, RR 24 unlabored, BP 138/84 right arm sitting, SpO2 96% RA. Abdomen distended, hypoactive bowel sounds all four quadrants, guarding on light palpation RLQ. Provider Dr. Okoye paged 0305.” | “Stable” is a conclusion with no data behind it; the precise entry proves what was assessed, when, and that escalation occurred |
| “Patient is confused.” | “Patient oriented to person only; unable to state place, month or year. Was oriented x4 at 0800. Follows one-step commands. Pulls at IV line.” | Baseline plus specific deficit converts an impression into a trend a provider can act on |
| “Wound looks better.” | “Sacral wound 3.0 cm x 2.5 cm x 0.4 cm, pink granulation over 80% of the base, scant serosanguineous drainage, no odor, periwound skin intact and warm without induration.” | Measurements let the next nurse detect deterioration; “better” is not comparable to anything |
| “Refused meds. Uncooperative.” | “Patient declined metoprolol at 0900, stating ‘it makes me dizzy when I stand up.’ Education provided on purpose and on reporting dizziness. Dr. Okoye notified 0910; dose held per order.” | “Uncooperative” is a judgment and is potentially defamatory; the quote, the teaching and the notification are the defensible record |
Inspect, palpate, percuss, auscultate — abdomen excepted — then chart the measured finding rather than your impression, because in a review, care that was not documented is care that was not given.
Section 5Recognizing Trouble and Escalating It
Failure to rescue, and the findings that mean now
Failure to rescue is the term for a patient who deteriorates and dies not because the complication was unpredictable, but because the warning signs were recorded and not acted upon. Reviews of these events consistently find abnormal vital signs documented for six to eight hours before the arrest — most often a rising respiratory rate, which is the earliest and most ignored warning sign in adult medicine. The nurse is the surveillance system. Nobody else is in the room every hour.
| Red flag | Threshold | Why it matters | Act |
|---|---|---|---|
| Respiratory rate | Below 8 or above 28 breaths/min; new accessory muscle use, retractions, tripod position, or inability to speak in full sentences | Earliest marker of impending deterioration and of opioid oversedation | Stay with the patient, sit upright, apply oxygen, rapid response; if the cause is opioid oversedation, stimulate, support ventilation and give naloxone per protocol |
| Oxygen saturation | Below 90% on room air, or below the individually ordered target, or a new oxygen requirement | Hypoxemia; a new oxygen need is itself an escalation trigger | Apply oxygen, reassess, escalate |
| Heart rate | Below 40 or above 130 beats/min; new irregular rhythm | Perfusion failure, arrhythmia, drug toxicity | Full 60-second apical pulse, ECG per protocol, notify provider |
| Blood pressure | Systolic below 90 mm Hg, or a drop of 40 mm Hg from that patient’s baseline; mean arterial pressure below 65 | Organ hypoperfusion, shock, bleeding | Recheck manually on the opposite arm with a correctly sized cuff, lay the patient flat (left lateral tilt if pregnant beyond 20 weeks; keep the head raised if breathing is labored), escalate immediately |
| Temperature | Above 39.4 °C (103 °F) or below 35.0 °C (95.0 °F); in older adults, 37.8 °C (100 °F) or a 1.1 °C (2 °F) rise above baseline | Sepsis presents as hypothermia as often as fever in the frail | Sepsis screen, cultures and antibiotics per protocol |
| Level of consciousness | Any new confusion, agitation, lethargy or unresponsiveness | Altered mentation is a core sepsis and shock criterion and often the first sign in older adults | Check glucose, oxygen saturation; escalate |
| Neurologic deficit | Sudden facial droop, arm drift, slurred speech, vision loss, worst-ever headache | Stroke — treatment is time-dependent | Activate the stroke alert, establish the time last known well, check a glucose, and keep the patient nothing by mouth until a swallow screen is passed |
| Chest pain | New chest pain or pressure, with or without diaphoresis, nausea, or jaw or arm radiation | Acute coronary syndrome; women, older adults and people with diabetes present atypically | Stay, vital signs, 12-lead ECG per protocol, notify immediately |
| Urine output | Less than 30 mL/hour for 2 consecutive hours | Hypoperfusion or acute kidney injury | Assess volume status and bladder; notify provider |
| Pediatric | Grunting, nasal flaring, head bobbing, retractions, no wet diaper in 8 hours, inconsolability — and any hypotension | Children compensate until they do not; hypotension in a child is a pre-arrest sign | Escalate immediately; do not wait for a repeat set |
| Parent or patient concern | “Something is wrong,” “this isn’t like him” | A validated predictor of deterioration in its own right | Take it as a vital sign and reassess in person |
SBAR: the escalation script
SBAR — Situation, Background, Assessment, Recommendation — exists because unstructured calls fail. Before you dial, have the chart open, the most recent vital signs in front of you, the allergy list, the pertinent medications and the code status, and have laid eyes on the patient yourself within the last few minutes. Then say it in this order.
S — Situation. “Dr. Okoye, this is Priya Menon, RN, on 4 West. I’m calling about Mr. Daniel Ruiz in room 412, post-op day one from a right hemicolectomy. His respiratory rate has climbed to 28 and his oxygen saturation has dropped to 88% on room air.” B — Background. “He’s 68, with COPD and type 2 diabetes. He came back from the OR yesterday at 1400. He’s had 6 mg of morphine IV in the last four hours, last dose at 0230. He hasn’t been out of bed since surgery.” A — Assessment. “Right now he’s tachypneic and anxious, speaking in three-word sentences. Heart rate 122 sinus tach, blood pressure 98/56, temperature 37.9 °C. Breath sounds are diminished at both bases with no wheeze. His right calf is 3 cm larger than the left and tender. I’m concerned about a pulmonary embolism.” R — Recommendation. “I’ve placed him on 2 liters by nasal cannula and sat him upright. I’d like you to come see him now. Can I get orders for a stat CT pulmonary angiogram, a 12-lead ECG and an arterial blood gas? And what oxygen saturation target do you want, given his COPD?”
Notice four things about that call. It named the nurse and the unit; it gave the numbers rather than adjectives; it stated a concern out loud rather than hinting at one; and it closed with a specific, answerable request. Then document it: “0310 Dr. Okoye notified of RR 28, SpO2 88% RA, HR 122, BP 98/56, right calf tenderness. Verbal orders received for stat CTPA, ECG, ABG; SpO2 target 88–92%. Read back and verified. Provider to bedside.”
Advocacy, the chain of command and speaking up
Escalation does not stop at one phone call. If the provider does not respond, or responds in a way you believe is unsafe, you go up the chain of command: charge nurse, then nursing supervisor or manager, then the attending physician, then the medical director or administrator on call. Most facilities also have a rapid response team that any nurse may activate without a physician’s permission for a patient who is deteriorating but has not arrested, and many now extend that activation to patients and families. Calling a rapid response is never wrong; the near-miss you prevent is invisible, and the arrest you failed to prevent is not.
When you are ignored, use the two-challenge rule: state your concern clearly twice, and if it is still not acknowledged, take it to the next level of the chain. Structured phrases exist for this because in the moment people go quiet. The CUS script escalates the language deliberately: “I am Concerned. I am Uncomfortable. This is a Safety issue — I need us to stop.” That last sentence is the one to memorize, because the moments when you most need it are the moments when you will least want to say it.
Advocacy also runs in the ordinary direction: making sure the patient understands what they consented to, that pain is treated, that the discharge plan matches the home the person is actually going to, and that the frightened family gets an explanation. Two patient identifiers — full name and date of birth, never the room number — before every medication, specimen and procedure. Hand hygiene before and after every patient contact. These are not junior tasks you outgrow; they are the practice.
Deterioration is almost always visible in the vital signs hours before the arrest — recognize the red flag, escalate with SBAR, and keep escalating up the chain of command until someone acts.
The chapter in one breath
Nursing is a licensed practice defined by a state statute — the Nurse Practice Act — and enforced by a board of nursing, and the license, not the employer, sets the outer limit of what you may do. Before any unfamiliar task, test it against the practice act, then facility policy and orders, then your own validated competence; a no at any level means you stop and find someone qualified. You may delegate tasks that are predictable and low-risk to unlicensed personnel using the five rights of delegation, but you keep the accountability, and assessment, nursing diagnosis and planning, teaching, evaluation and any care of an unstable patient never leave the registered nurse. You will be judged against the standard of care, built from the ANA standards, the Code of Ethics and the law of negligence, and the record you write is the evidence. Physical examination proceeds by inspection, palpation, percussion and auscultation — except the abdomen, where auscultation moves ahead of percussion and palpation. Know adult vital-sign ranges exactly, adjust them for infants, children, pregnancy and older adults, and look for cyanosis, jaundice, pallor and erythema on mucosa, conjunctivae, sclerae and palms rather than trusting surface color. When a red flag appears, escalate with SBAR — and keep escalating.
Words worth knowing
| Term | What it means |
|---|---|
| Nurse Practice Act (NPA) | The state statute that defines nursing practice, sets licensure requirements and creates the board of nursing; it is the legal ceiling on your scope. |
| Board of nursing (BON) | The state agency that issues, renews, disciplines and revokes nursing licenses and writes the rules that interpret the NPA. |
| Nurse Licensure Compact (NLC) | An agreement letting a multistate license from one compact state authorize practice in the others; you follow the law of the state where the patient is located. |
| Scope of practice | The set of activities a licensee is legally permitted to perform, limited further by facility policy and by individual competence. |
| Standard of care | What a reasonably prudent nurse with similar preparation would do in similar circumstances; the yardstick in any negligence review. |
| Assignment | Transferring both responsibility and accountability for work already within the receiving person’s own scope and job description. |
| Delegation | Transferring responsibility for performing a specific task to another person while the delegating RN retains accountability for the outcome. |
| Five rights of delegation | Right task, right circumstance, right person, right direction and communication, right supervision and evaluation. |
| Unlicensed assistive personnel (UAP) | Certified nursing assistants, patient care technicians and similar staff who perform delegated, predictable, low-risk tasks for stable patients. |
| Negligence / malpractice | Failure to act as a reasonably prudent person would; malpractice is professional negligence, requiring duty, breach, causation and damages. |
| Battery | Unconsented physical contact, including performing a procedure a competent patient has refused. |
| Informed consent | The provider’s duty to explain diagnosis, procedure, risks, benefits, alternatives and consequences of refusal; the nurse verifies understanding and voluntariness and witnesses the signature. |
| Inspection, palpation, percussion, auscultation | The four physical-examination techniques, performed in that order — except on the abdomen. |
| Abdominal exception | Inspect, auscultate, percuss, palpate — auscultation precedes touch because palpation alters bowel sounds. |
| Orthostatic hypotension | A fall of at least 20 mm Hg systolic or 10 mm Hg diastolic within three minutes of standing; a marker of volume depletion and fall risk. |
| Mean arterial pressure (MAP) | Systolic plus twice the diastolic, divided by three; at least 65 mm Hg is generally required to perfuse organs. |
| Failure to rescue | Death or serious harm following a recognizable complication whose warning signs were documented but not acted upon. |
| SBAR | Situation, Background, Assessment, Recommendation — the standardized structure for escalating a concern or handing off a patient. |
| Rapid response team | A team any nurse may activate, without a physician’s permission, for a deteriorating patient who has not yet arrested. |
| Two-challenge rule / CUS | State a safety concern twice and escalate if unacknowledged, using the words “I am Concerned, I am Uncomfortable, this is a Safety issue.” |
