Preparing for the National Council Licensure Examination (NCLEX-RN or NCLEX-PN) is the final, most critical step in your nursing journey. With the recent transition to the Next Generation NCLEX (NGN) and the introduction of the Clinical Judgment Measurement Model (NCJMM), the exam has evolved. It no longer just tests your ability to memorize textbooks; it tests your ability to think like a safe, entry-level nurse in high-stakes clinical scenarios.
Because the NCLEX uses Computerized Adaptive Testing (CAT), every candidate’s exam is unique. The computer algorithm adjusts the difficulty of the questions based on your previous answers. However, the National Council of State Boards of Nursing (NCSBN) strictly adheres to a "Test Plan" that dictates the percentage of questions drawn from specific content areas.
By analyzing the NCSBN Test Plan and recent NGN question trends, we can pinpoint exactly where you need to focus your study efforts. Here is a comprehensive breakdown of the most tested topics on the NCLEX.
1. The Foundation: Understanding the NCLEX Blueprint
Before diving into specific diseases and drugs, you must understand the overarching categories the exam pulls from. The NCSBN divides the exam into four major "Client Needs" categories. Knowing the weight of these categories reveals the exam's true priorities:
- Safe and Effective Care Environment:
- Management of Care (RN) / Coordinated Care (PN): 15–21% (The heaviest weighted section)
- Safety and Infection Control: 10–16%
- Physiological Integrity:
- Pharmacological and Parenteral Therapies: 13–19% (The second heaviest section)
- Physiological Adaptation: 11–17%
- Reduction of Risk Potential: 9–15%
- Basic Care and Comfort: 6–12%
- Health Promotion and Maintenance: 6–12%
- Psychosocial Integrity: 6–12%
Based on these percentages, Management of Care and Pharmacology together make up over one-third of your entire exam. If you master these two areas, you are well on your way to passing.

2. Trend #1: Management of Care (Prioritization and Delegation)
You are guaranteed to see a massive amount of prioritization and delegation questions. The NCLEX wants to know if you can manage a busy floor, delegate safely, and identify which patient is closest to death.
Prioritization: Who Do You See First?
When given four patients and asked who to assess first, you must apply specific frameworks:
- ABCs (Airway, Breathing, Circulation): A patient with stridor or an O2 saturation of 85% always trumps a patient with a blood pressure of 160/90.
- Maslow’s Hierarchy of Needs: Physiological needs (oxygen, fluids, nutrition) come before psychosocial needs (anxiety, education).
- Acute vs. Chronic: A patient with a sudden onset of chest pain (acute) is a higher priority than a patient with a 10-year history of COPD who is currently short of breath (chronic).
- Stable vs. Unstable: Look for words that indicate instability, such as "new-onset," "sudden," "worsening," "lethargic," or "hemorrhage." A patient who had surgery 3 days ago and is ready for discharge is stable; a patient who had surgery 2 hours ago and is restless is unstable (restlessness is an early sign of hypoxia/shock).
Delegation: The "EAT" Rule
You must know the scope of practice for Registered Nurses (RNs), Licensed Practical/Vocational Nurses (LPN/VN), and Unlicensed Assistive Personnel (UAP).
- Do not delegate what you can EAT: RNs cannot delegate Evaluation, Assessment, or Teaching.
- RN Scope: Initial assessments/new admission, initial client education, blood transfusions, IV push medications, and care of unstable patients.
- LPN/VN Scope: Care of stable patients, gathering data (routine vitals on stable patients), administering PO/SubQ/IM medications, reinforcing teaching (that the RN has already done), and performing routine procedures (foley catheter insertion, tracheostomy care).
- UAP Scope: ADLs (Activities of Daily Living), ambulation, feeding (unless the patient is at risk for aspiration), positioning, and routine vital signs on stable patients.
3. Trend #2: Pharmacological and Parenteral Therapies
You do not need to know every drug in the world, but you must know the "high-alert" medications, their antidotes, and their critical side effects. The NCLEX tests your knowledge of safe administration.
High-Yield Medication Categories
- Cardiovascular Drugs:
- ACE Inhibitors (ending in "-pril"): Watch for hyperkalemia, angioedema, and the notorious dry, hacking cough.
- Beta-Blockers (ending in "-olol"): Monitor for bradycardia and bronchospasm (do not give non-selective beta-blockers to asthma patients).
- Digoxin: Know the therapeutic range (0.5 - 2.0 ng/mL). Early signs of toxicity include GI distress (nausea/vomiting) and visual disturbances (yellow/green halos). Hypokalemia increases the risk of digoxin toxicity.
- Psychiatric Medications:
- Lithium: Narrow therapeutic range (0.6 - 1.2 mEq/L). Toxicity presents as tremors, confusion, and ataxia. Adequate sodium and fluid intake are crucial because hyponatremia leads to lithium retention.
- MAOIs: Risk of hypertensive crisis if taken with tyramine-rich foods (aged cheeses, cured meats, wine).
- Anticoagulants:
- Heparin: Monitor aPTT. The antidote is Protamine Sulfate.
- Warfarin (Coumadin): Monitor PT/INR. The antidote is Vitamin K.
- Insulins:
- Know the onset, peak, and duration of Rapid (Lispro), Short (Regular), Intermediate (NPH), and Long-acting (Glargine) insulins. The peak time is critical because that is when the patient is at the highest risk for hypoglycemia.
4. Trend #3: Next Generation NCLEX (NGN) Clinical Judgment Case Studies
The most significant trend in the modern NCLEX is the NGN format. You will face three unfolding Case Studies (each containing 6 questions) based on an Electronic Health Record (EHR). These test the 6 steps of the NCJMM:
- Recognize Cues: What data is abnormal? (e.g., highlighting abnormal lab values in the EHR).
- Analyze Cues: What do these abnormalities mean? (e.g., linking a high WBC count and fever to an infection).
- Prioritize Hypotheses: What is the most likely or most dangerous problem?
- Generate Solutions: What interventions are appropriate? (e.g., selecting orders from a provider's list).
- Take Action: How will you implement the solution? (e.g., knowing to hang fluids before administering antibiotics in sepsis).
- Evaluate Outcomes: Did the intervention work? (e.g., looking at a trended vital sign chart to see if blood pressure stabilized).
Trend Questions: The NGN specifically uses "trend" questions where you must look at data over time (e.g., a patient's vitals taken at 0800, 1200, and 1600) to determine if the patient is improving, declining, or experiencing a drug complication.
5. Trend #4: Safety and Infection Control
Patient safety is paramount. You must memorize isolation precautions, as these are heavily tested through drag-and-drop or multiple-response formats.
Isolation Precautions
- Airborne Precautions: N95 mask, negative pressure room.
- Mnemonic: "My Chicken Hez TB" (Measles, Chickenpox/Varicella, Herpes Zoster/Shingles, Tuberculosis).
- Droplet Precautions: Standard surgical mask, private room.
- Mnemonic: "SPIDERMAN" (Sepsis, Scarlet fever, Streptococcal pharyngitis, Parvovirus, Pneumonia, Pertussis, Influenza, Diphtheria, Epiglottitis, Rubella, Mumps, Meningitis, Mycoplasma).
- Contact Precautions: Gown and gloves.
- Mnemonic: "MRS. WEE" (Multidrug-resistant organisms like MRSA/VRE, Respiratory infection like RSV, Skin infections, Wound infections, Enteric infections like C. diff, Eye infections like conjunctivitis). Note: C. diff requires handwashing with soap and water; alcohol-based sanitizers do not kill the spores.

Equipment and Fall Safety
Expect questions on the proper use of assistive devices (canes, crutches, walkers). Remember: "Up with the good, down with the bad" for stairs. Restraints are a last resort, and you must know the legal and physiological monitoring requirements (checking pulses and skin integrity every 2 hours).
6. Trend #5: Physiological Adaptation (Med-Surg Core)
This section tests your knowledge of how diseases disrupt the human body. Expect highly specific questions on managing acute crises.
- Fluids, Electrolytes, and Acid-Base:
- Potassium: Hyperkalemia causes peaked T-waves; hypokalemia causes U-waves and muscle cramps. Both can cause lethal arrhythmias.
- Calcium: Hypocalcemia leads to tetany, positive Chvostek’s sign (facial twitch), and Trousseau’s sign (carpal spasm).
- ABGs: Use the ROME mnemonic (Respiratory Opposite, Metabolic Equal) to interpret Respiratory Acidosis/Alkalosis and Metabolic Acidosis/Alkalosis.
- Endocrine Emergencies:
- Understand the difference between Diabetic Ketoacidosis (DKA - Type 1, ketones, Kussmaul respirations, treated with IV regular insulin and hydration) and Hyperosmolar Hyperglycemic State (HHS - Type 2, extreme dehydration, no ketones).
- Thyroid storms (Hyperthyroidism) vs. Myxedema coma (Hypothyroidism).
- Cardio and Pulmonary:
- Heart Failure: Differentiate right-sided (systemic edema, JVD, ascites) from left-sided (pulmonary edema, crackles, shortness of breath).
- Chest Tubes: Know what continuous bubbling in the water seal chamber means (an air leak!) versus intermittent bubbling (normal).
7. Trend #6: Maternal, Newborn, and Pediatrics
While not the largest section, Maternal/Newborn questions often trip up candidates who did not specialize in this area.
- Fetal Heart Rate Monitoring: Memorize the VEAL CHOP mnemonic:
- Variable decelerations = Cord compression (Intervention: Move mother to her side).
- Early decelerations = Head compression (Normal, document it).
- Accelerations = Okay (Normal fetal well-being).
- Late decelerations = Placental insufficiency (Emergency: Turn mom to the left side, apply O2, stop Pitocin, give IV fluids).
- Pediatrics: Focus on developmental milestones (e.g., when a child should sit up, crawl, walk) to identify developmental delays in case scenarios. Congenital heart defects (Tetralogy of Fallot) and respiratory illnesses (Cystic Fibrosis, Croup) are also high-yield.
8. Trend #7: Psychosocial Integrity and Mental Health
The NCLEX evaluates your ability to communicate effectively and manage psychiatric crises.
- Therapeutic Communication: The NCLEX is a "perfect world" hospital. When selecting a response to a patient, never ask "Why?" (it makes them defensive). Never say "Don't worry" (it dismisses their feelings). Always acknowledge their feelings, use open-ended questions, and focus on the client, not the nurse or the family.
- Psychiatric Emergencies: Be able to identify Serotonin Syndrome, Neuroleptic Malignant Syndrome (caused by antipsychotics; presents with extreme fever and muscle rigidity), and the manic phases of Bipolar Disorder (interventions include finger foods and decreasing environmental stimuli).
Frequently Asked Questions (FAQs)
Q1: What are "trend" questions on the Next Generation NCLEX (NGN)?
A: Trend questions are a specific NGN item type where you are provided with client data collected over a period of time (e.g., flowsheets, vital sign charts spanning 8 hours). You must analyze this data to determine if the patient's condition is improving, worsening, or if a complication has arisen. This mimics real-world nursing where patient status is dynamic.
Q2: Are the NGN questions scored differently?
A: Yes. In the past, all NCLEX questions were graded as either completely right or completely wrong (dichotomous scoring). The NGN introduces partial credit scoring for complex items like Multiple Response (Select All That Apply), Matrix/Grid, and Drop-down questions. This is beneficial, as you can earn points for the parts of the question you get right without being penalized for the whole item.
Q3: How many questions will I have to take on the NCLEX?
A: Due to the Computerized Adaptive Testing format, the exam length varies. The minimum number of questions for both the RN and PN exams is 85, and the maximum is 150. Of the first 85 questions, 15 are unscored "pretest" items used for future exams. Your exam will shut off when the computer has determined, with 95% certainty, that your ability is clearly above or clearly below the passing standard.
Q4: If I am terrible at Pharmacology, can I still pass?
A: It is possible, but it is dangerous. The computer algorithm identifies your weak areas. If you keep getting pharmacology questions wrong, the computer will continue to serve you pharmacology questions to determine your competency level. If you fall below the minimum standard in the Physiological Integrity category, you will fail, regardless of how well you did in Management of Care.
Q5: What is the most common reason candidates fail?
A: Failing to grasp the concepts of Prioritization and Delegation. Because Management of Care makes up the highest percentage of the exam (15-21%), lacking critical thinking in "who to see first" scenarios will severely impact your score. Memorizing facts is not enough; you must know how to apply them.
