The Nursing Process, ADPIE
ADPIE is the systematic problem-solving framework that guides all nursing care. It stands for Assessment, Diagnosis, Planning, Implementation, and Evaluation. Every nursing action you take in clinical practice, and every NCLEX question you answer, connects back to one of these five steps.
Assessment Comes First
You cannot diagnose, plan, or intervene without data. Assessment involves systematic collection of subjective data (patient reports) and objective data (vital signs, lab values, physical exam findings).
Nursing Diagnosis vs. Medical Diagnosis
Nursing diagnosis is distinct from medical diagnosis. It identifies human responses to health conditions. For example, "Risk for Falls" rather than "Osteoporosis." Diagnoses follow PES format: Problem related to Etiology as evidenced by Signs/Symptoms.
Planning, Implementation, and Evaluation
Planning involves setting SMART outcomes: Specific, Measurable, Achievable, Relevant, Time-bound. Implementation is carrying out the plan. Evaluation asks whether outcomes were achieved, and the cycle repeats. Flashcard drilling on ADPIE helps you identify which step a given action belongs to, one of the most common NCLEX question formats.
| Term | Meaning |
|---|---|
| Assessment | First step of the nursing process. Systematic collection of subjective data (patient reports) and objective data (vital signs, lab values, physical exam findings). Must be completed before any nursing diagnosis or intervention. |
| Nursing Diagnosis | Clinical judgment about human responses to health conditions. Written in PES format: Problem related to Etiology as evidenced by Signs/Symptoms. Example: 'Impaired Gas Exchange related to fluid in alveoli as evidenced by SpO2 of 88% and crackles on auscultation.' |
| Planning, SMART Outcomes | Setting Specific, Measurable, Achievable, Relevant, Time-bound patient goals. Example: 'Patient will ambulate 100 feet in hallway with a walker independently by discharge on post-op day 3.' |
| Implementation | Carrying out the nursing care plan. Includes direct care (administering medications, wound care), patient teaching, delegation, and documentation. All interventions must be evidence-based and within scope of practice. |
| Evaluation | Final step, determining whether patient outcomes were met. If outcomes are not met, reassess and revise the care plan. Evaluation makes the nursing process cyclical rather than linear. |
Vital Signs and Normal Ranges
Accurate vital sign measurement and interpretation is the most frequently performed nursing skill. You must know normal adult ranges, pediatric variations, factors that influence each vital sign, and when to report abnormalities.
Why Vital Signs Matter
Temperature, pulse, respiration, blood pressure, and oxygen saturation are assessed at every patient encounter. Understanding the physiology behind each vital sign helps you anticipate findings. Why does fever increase heart rate? Why does orthostatic hypotension occur? These connections deepen your mastery beyond memorization.
Key Variations by Site
Temperature varies by measurement site. Rectal readings run about 1 degree Fahrenheit higher than oral. Axillary readings run about 1 degree lower. Temporal readings are similar to oral. Always note the site in documentation.
| Term | Meaning |
|---|---|
| Temperature, 97.8-99.1°F (36.5-37.3°C) | Core temperature varies by site: oral is standard, rectal is 1°F higher, axillary is 1°F lower, temporal is similar to oral. Fever (pyrexia) >100.4°F (38°C). Hypothermia <95°F (35°C). Fever increases metabolic rate 7% per degree Fahrenheit. |
| Pulse, 60-100 bpm (adult) | Tachycardia >100 bpm (fever, pain, anxiety, hemorrhage, hypoxia). Bradycardia <60 bpm (athletes, beta blockers, increased ICP). Assess rate, rhythm, and quality. Apical pulse is the most accurate, assess for a full minute if irregular. |
| Blood Pressure, <120/80 mmHg (normal adult) | Hypertension Stage 1: 130-139/80-89. Stage 2: ≥140/≥90. Hypertensive crisis: >180/120. Orthostatic hypotension: drop of ≥20 mmHg systolic or ≥10 mmHg diastolic upon standing. Wait 1-3 minutes before reassessing after position change. |
| Oxygen Saturation (SpO2), 95-100% | Measured via pulse oximetry. <95% indicates hypoxemia, assess respiratory status and notify provider. <90% requires immediate intervention (supplemental O2, position change, airway assessment). False readings: nail polish, cold extremities, poor perfusion, dark skin pigmentation. |
Infection Control and Safety
Infection control is a pillar of nursing fundamentals and a major NCLEX content area. The chain of infection has six links: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. Break any link to stop infection spread.
Standard Precautions Apply Universally
Standard precautions apply to ALL patients regardless of diagnosis. They include hand hygiene, personal protective equipment (PPE) use, safe injection practices, and respiratory hygiene. These protect you and your patients.
Transmission-Based Precautions
Transmission-based precautions are added based on the specific pathogen. Contact precautions prevent spread via direct contact. Droplet precautions prevent spread through respiratory droplets. Airborne precautions prevent spread through airborne particles. Patient safety also includes falls prevention, use of side rails, proper body mechanics, and fire safety (RACE and PASS acronyms). NCLEX frequently presents infection control scenarios and asks you to identify the correct nursing action.
| Term | Meaning |
|---|---|
| Standard Precautions | Applied to ALL patients. Include hand hygiene (before and after every patient contact), gloves for contact with blood/body fluids, gown if clothing may be soiled, mask/eye protection if splash risk. Based on the principle that all blood and body fluids are potentially infectious. |
| Airborne Precautions | For pathogens that remain suspended in air: tuberculosis (TB), measles, varicella (chickenpox). Requires negative-pressure room and N95 respirator (fit-tested). Mnemonic: 'My Chicken Fried TB' (Measles, Chickenpox, TB). |
| Contact Precautions | For pathogens spread by direct or indirect contact: C. diff, MRSA, VRE, scabies. Requires gloves and gown upon room entry. Dedicated patient equipment. C. diff requires soap and water hand washing (alcohol gel is not effective against spores). |
| Six Rights of Medication Administration | Right patient, right drug, right dose, right route, right time, right documentation. Many programs add: right reason, right response, right to refuse. Check the MAR three times before administering. Two patient identifiers required (name + DOB, not room number). |
Documentation and Therapeutic Communication
Nursing documentation serves as a legal record of care, a communication tool among the healthcare team, and the basis for reimbursement. The principle is clear: "If it wasn't documented, it wasn't done." Fundamentals courses teach charting by exception, narrative notes, and SBAR communication (Situation, Background, Assessment, Recommendation).
Focus Charting and DAR Format
Focus charting uses the DAR format: Data, Action, Response. This structured approach ensures complete documentation and makes care handoffs clearer and safer.
Therapeutic Communication Is Your Primary Tool
Therapeutic communication is equally critical. It is your primary tool for building rapport, assessing patient concerns, and providing emotional support. Use open-ended questions, reflection, paraphrasing, silence, and offering self. Avoid non-therapeutic responses like giving advice, false reassurance, asking "why," or changing the subject. NCLEX frequently presents communication scenarios and asks you to identify therapeutic versus non-therapeutic responses.
