Fundamentals of Nursing

Nursing process, vital signs, medical terminology, hygiene, mobility, and clinical judgment.

Nursing Process

The Nursing Process — ADPIE

StepWhat You DoKey Point
AssessCollect subjective and objective dataALWAYS the first step
DiagnoseIdentify nursing diagnosesRN role — LPN contributes data
PlanSet goals and outcomesRN initiates — LPN implements
ImplementCarry out nursing interventionsLPN's primary role
EvaluateDetermine if goals were metReassess and revise
NCLEX Rule: Assessment is ALWAYS first unless the patient's airway, breathing, or circulation is already compromised.

Vital Signs

Vital Signs — Normal Ranges

Vital SignAdult NormalCritical Values
Temperature36.1–37.2°C (97–99°F)Fever >38.3°C | Hypothermia <35°C
Pulse60–100 bpm (apical)Brady <60 | Tachy >100
Respirations12–20 breaths/min<12 or >20 = intervene
BP (Adult)120/80 mmHgHypertension ≥130/80 | Hypotension <90/60
SpO295–100%<90% = emergency
Pain0 = no pain5th vital sign — always assess
⚠️
Before any cardiac medication: Check apical pulse for 1 full minute. Hold and notify if <60 bpm (digoxin, beta blockers, diltiazem).

Medical Terminology

Essential Medical Terminology

Prefix/SuffixMeaningExample
Brady-SlowBradycardia = slow heart
Tachy-FastTachypnea = fast breathing
Hypo-Below normal / lowHypotension = low BP
Hyper-Above normal / highHyperglycemia = high glucose
-emiaBlood conditionAnemia = low blood (cells)
-uriaUrine conditionHematuria = blood in urine
-ostomySurgical openingColostomy = opening in colon
-ectomySurgical removalAppendectomy = remove appendix
Peri-AroundPerioperative = around surgery
Post-AfterPostpartum = after birth

Clinical Judgment

Clinical Judgment — How to Think Like a Nurse

🧠
NCLEX Clinical Judgment Model (NCSBN):
1. Recognize Cues → 2. Analyze Cues → 3. Prioritize Hypotheses → 4. Generate Solutions → 5. Take Actions → 6. Evaluate Outcomes
🚨
Recognizing Patient Deterioration: Look for change from baseline — sudden confusion, new shortness of breath, dropping BP, rising HR, decreased urine output, or change in mental status are RED FLAGS regardless of diagnosis.
ABC Priority Rule: Airway → Breathing → Circulation → Safety. When unsure which patient to see first, go to the one with ABC compromise first.
📋
Modifying Phrase Rule: ALWAYS read the entire question. Words like "sudden," "new," "acute," "unrelieved," or "worsening" change your answer — these indicate the HIGHER priority patient.

📖 Study Notes

📋
Nursing Process mnemonic — ADPIE: Always Do Plan It Exactly. Assessment first — ALWAYS.
💡
Objective vs Subjective data: Objective = what you OBSERVE (BP, temp, breath sounds). Subjective = what the patient TELLS you ("I feel dizzy").
🔢
Vital sign memory: Normal adults — HR 60–100, RR 12–20, BP 120/80, Temp 98.6°F (37°C), SpO2 95–100%.
⚠️
Critical VS to memorize: RR <10 = respiratory emergency. Urine output <30 mL/hr for 2 hrs = call provider. BP <90/60 = shock protocol.
