Memory tricks

Proven mnemonics — fast to learn, hard to forget.

SATA Strategy
Select All That Apply (SATA): treat each option as True/False independently. Don't look for patterns — every option stands alone.
SATA Questions
The most feared NCLEX question type — and the strategy that makes them manageable
SATA questions have no partial credit — all correct options must be selected. Strategy: cover other options, read each one independently as True/False. Avoid: looking for patterns (2 and 4, all of the above thinking). Each option is its own T/F question. If unsure about one option — ask 'would a safe nurse do this?' Common trap: including an intervention that's appropriate but NOT the priority or NOT related to the specific scenario. Always re-read the stem after selecting to make sure your answers make clinical sense together.
Maslow's Hierarchy
Maslow: Physiological → Safety → Love/Belonging → Esteem → Self-Actualization. 'Please Send Love Every Saturday.'
Maslow's Hierarchy of Needs
The framework NCLEX uses to prioritize nursing care — physical needs always come first
Physiological: oxygen, food, water, shelter, sleep, elimination — ALWAYS first priority. Safety: security, protection from harm, falls prevention. Love/Belonging: relationships, family, social connection. Esteem: self-confidence, achievement, respect. Self-Actualization: reaching full potential. NCLEX application: patient with breathing problem AND anxiety → treat breathing first. Patient with pain AND loneliness → treat pain first. Exception: immediate safety threat (suicidal ideation) → safety before some physiological needs.

Infection Control — Transmission Precautions
Contact (gloves+gown), Droplet (surgical mask), Airborne (N95 + negative pressure room). 'My Aunt Takes Careful, Droplet, Airborne steps.'
Transmission-Based Precautions
Three types of isolation — knowing which goes with which infection is essential NCLEX content
Standard precautions: for ALL patients — hand hygiene, gloves for body fluids. Contact precautions (gloves + gown): MRSA, VRE, C. diff, scabies, RSV. Private room preferred. Droplet precautions (surgical mask within 3 feet): influenza, pertussis, meningitis (meningococcal), mumps, rubella, strep pharyngitis. Airborne precautions (N95 + negative pressure room): TB, measles (rubeola), varicella (chickenpox), disseminated zoster. Mnemonic for airborne: MTV — Measles, TB, Varicella. N95 must be fit-tested. Patient wears surgical mask when transported.
Contact
Gloves + gown — MRSA, VRE, C. diff
Droplet
Surgical mask — flu, meningitis, mumps
Airborne
N95 + neg pressure — MTV: Measles, TB, Varicella
Vital Signs — Normal Ranges
Normal adult vitals: BP 120/80, HR 60–100, RR 12–20, Temp 36.5–37.5°C (97.7–99.5°F), SpO2 ≥95%.
Normal Adult Vital Signs
The baseline every nurse must know cold — and when to call the provider
Blood pressure: normal <120/80, hypertension ≥130/80, hypotension <90/60. Heart rate: 60–100 bpm. Tachycardia >100 (pain, fever, hypovolemia, anxiety). Bradycardia <60 (athletes normal, beta blockers, increased ICP). Respiratory rate: 12–20 breaths/min. Tachypnea >20 (fever, pain, anxiety, respiratory distress). Bradypnea <12 (opioids — hold medication). Temperature: 36.5–37.5°C. Fever >38°C (100.4°F). SpO2: ≥95% normal, <90% concerning, <88% critical. Pulse pressure: systolic - diastolic = 40 mmHg normal. Widening pulse pressure = increased ICP.
Pain Assessment
Pain: 5th vital sign. OLDCART — Onset, Location, Duration, Character, Aggravating, Relieving, Treatment. Always ask before giving meds.
Pain Assessment
Comprehensive pain assessment — NCLEX expects nurses to assess before and after every intervention
OLDCART: Onset (when did it start?), Location (where? does it radiate?), Duration (constant or intermittent?), Character (sharp, dull, burning, crushing?), Aggravating factors (what makes it worse?), Relieving factors (what helps?), Treatment (what have you tried?). Pain scales: NRS 0–10 (adults), FACES (children 3+), FLACC (infants/non-verbal — Face, Legs, Activity, Cry, Consolability). Reassess: 30–60 min after oral meds, 15–30 min after IV. Document: location, quality, severity, response to treatment. Pain is subjective — believe the patient.

Fall Prevention
Fall risk: MORSE scale. High risk interventions: bed in lowest position, call light within reach, non-slip footwear, hourly rounding.
Fall Prevention
The most common adverse event in hospitals — preventing falls is a core nursing responsibility
MORSE Fall Scale risk factors: history of falls, secondary diagnosis, ambulatory aid (cane/walker), IV access, gait (weak/impaired), mental status (forgets limitations). High score = high risk. Interventions: bed lowest position and locked, call light within reach, non-slip footwear (socks with grips), keep personal items close, hourly rounding (4 Ps: Pain, Position, Potty, Personal items), bed alarm, yellow armband/door sign. High-risk medications: sedatives, opioids, antihypertensives, diuretics, antidiabetics. Do NOT restrain to prevent falls.
Restraints
Restraints: last resort, require MD order, release every 2 hours, neurovascular checks every 30 min, document every hour.
Restraint Use
Restraints are heavily regulated — the NCLEX tests safe and legal restraint use
Restraints: physical or chemical limitation of movement. Must have: MD order (time-limited), documented clinical justification, less restrictive alternatives tried first. Nursing responsibilities: restraint as LAST resort (try redirection, call family, sitter first). Check every 30 minutes: neurovascular status (circulation, sensation, movement). Release every 2 hours: reposition, ROM, toileting, skin care. Tie to bed frame (NOT side rail) with quick-release knot. Document every hour. Wrist restraints: keep 2 fingers under. Never restrain in prone position. Reassess need every shift.
IV Access and Complications
IV complications: infiltration (swelling, cool), phlebitis (red, warm, cord), extravasation (vesicant leaks — tissue damage).
IV Complications
Three common IV complications — assess the site with every intervention
Infiltration: IV fluid leaks into surrounding tissue (non-vesicant). Signs: swelling, cool, pale, pain at site. Stop infusion, remove IV, elevate extremity, warm compress. Phlebitis: vein inflammation. Signs: redness, warmth, pain along vein, palpable cord. Stop infusion, remove IV, warm compress, document. Extravasation: vesicant (tissue-damaging drug) leaks — most serious. Signs: burning, blistering, tissue necrosis. STOP immediately, leave IV in place, aspirate, give antidote per protocol. Examples of vesicants: chemotherapy, calcium chloride, potassium (concentrated), dopamine, vancomycin. Document site every 1–2 hours.
Infiltration
Non-vesicant leak — swelling, cool, pale
Phlebitis
Vein inflammation — red, warm, cord
Extravasation
Vesicant leak — STOP, aspirate, antidote
Therapeutic Communication
Therapeutic communication: open-ended questions, reflection, clarification. AVOID: false reassurance, why questions, giving advice.
Therapeutic Communication
The communication techniques NCLEX tests — and the common mistakes to avoid
Therapeutic techniques: Open-ended questions ('Tell me more about...'), Reflection (repeat back feelings), Clarification ('I'm not sure I understand...'), Active listening, Silence (powerful — allows patient to process), Focusing, Summarizing. Non-therapeutic (AVOID): False reassurance ('Everything will be fine'), Why questions ('Why did you...?' — puts patient on defensive), Giving personal opinions/advice, Changing the subject, Closed questions (yes/no only). For mental health: never argue with delusions, set limits on behavior (not feelings), don't agree with hallucinations but don't argue.
Use
Open-ended, reflection, silence, clarification
Avoid
False reassurance, 'why?' questions
Avoid
Giving advice, changing subject
Documentation Principles
Documentation: if it's not written, it wasn't done. Objective, accurate, timely, complete. Use military time. Never falsify.
Nursing Documentation
The legal and professional rules of nursing documentation — what NCLEX always includes
Charting rules: factual and objective (what you see, hear, smell — not interpretations). Accurate: exact times, measurements, quotes. Timely: document as soon as possible after care. Complete: assessments, interventions, patient response, teaching, referrals. Correct errors: single line through error, write 'error,' date, initials — NEVER white-out or delete. Late entries: clearly label as 'late entry' with date/time of actual occurrence. Legal: medical record is a legal document. Patient quotes: use exact words in quotation marks. Avoid vague terms: 'seems better' → use objective data.
Delegation — RN, LPN, UAP
RN delegates to LPN/UAP based on: stability, complexity, predictability. RN cannot delegate assessment, teaching, evaluation, or care planning.
Delegation Framework
What the RN can and cannot delegate — a perennial NCLEX topic
5 Rights of Delegation: Right Task, Right Circumstance, Right Person, Right Direction/Communication, Right Supervision. RN scope: assessment, care planning, teaching, evaluation, complex interventions, unstable patients. LPN scope: stable patients, routine medications (some states IV), wound care, data collection, reinforcing teaching. UAP (CNA) scope: ADLs (bathing, feeding, ambulation), vital signs (stable patients), I&O, specimen collection, positioning. NEVER delegate to UAP: assessment, teaching, evaluation, care planning, unstable patients, complex procedures. RN remains accountable for all delegated tasks.
