Nursing Fundamentals
Five core domains. One licensing exam. This Nursing Fundamentals quiz covers the concepts that appear most consistently on the NCLEX-RN and in nursing school assessments: patient assessment, pharmacology, infection control, fluid balance, and the nursing process. Questions are written at NCLEX application and analysis levels.
What This Nursing Fundamentals Quiz Covers
Nursing Fundamentals is the foundation of clinical practice. Before you can specialize in med-surg, pediatrics, critical care, or any other area, you need an airtight understanding of the core competencies: assessing patients accurately, administering medications safely, preventing infection, managing fluid and electrolyte imbalances, and applying the nursing process to clinical decision-making.
This quiz targets the five domains that appear most heavily on the NCLEX-RN and in nursing school exams: patient assessment and vitals, pharmacology basics, infection control and safety, fluid and electrolyte balance, and the nursing process and critical thinking. Questions are written at the application and analysis levels β not just "what is X?" but "given this scenario, what should the nurse do first?"
π₯ What the NCLEX-RN actually tests
The NCLEX uses Next Generation NCLEX (NGN) format with case studies that test clinical judgment across a six-step model: recognize cues, analyze cues, prioritize hypotheses, generate solutions, take action, and evaluate outcomes. This quiz trains the underlying knowledge base those steps depend on.
How to Use This Quiz for NCLEX Prep
The NCLEX is a pass/fail exam that adapts to your ability level, giving you harder questions as you answer correctly. That means it's testing the upper edge of your knowledge at all times. Rote memorization of drug names or normal vital sign ranges is necessary but not sufficient β the exam demands application.
Use this quiz in two modes. First pass: play through quickly to find your weakest content areas. Second pass: for every question you miss, write a one-sentence clinical rationale for the correct answer. "The nurse should assess breath sounds first because crackles indicate fluid accumulation consistent with fluid overload" is the level of reasoning the NCLEX rewards.
π‘ Study tips for nursing students
Prioritize using ABCs + Maslow. When a question asks "what does the nurse do first?" β airway, breathing, circulation trump everything else. After physiological needs, safety. This framework answers roughly 60% of priority questions.
Learn drug classes, not just drug names. Beta-blockers, ACE inhibitors, loop diuretics, opioids β knowing the class mechanism lets you reason about any drug in the class without memorizing each one individually.
Practice "SATA" questions. Select-all-that-apply questions are the NCLEX format students struggle with most. This quiz includes multi-select reasoning to build that skill.
For clinical rotations, the nursing process framework (ADPIE: Assess, Diagnose, Plan, Implement, Evaluate) is the scaffold for every patient interaction. Questions on this quiz reinforce that structure by presenting clinical scenarios rather than isolated facts.

Normal Laboratory Values Reference
These are the values most commonly tested on the NCLEX and in nursing school exams. Know the normal ranges and β more importantly β what abnormal values indicate clinically.
| Lab Value | Normal Range | Low (Hypo-) Indicates | High (Hyper-) Indicates |
|---|---|---|---|
| Sodium (NaβΊ) | 136β145 mEq/L | Hyponatremia: fluid overload, SIADH, diuretic use | Hypernatremia: dehydration, diabetes insipidus, high sodium intake |
| Potassium (KβΊ) | 3.5β5.0 mEq/L | Hypokalemia: muscle weakness, flat T waves, arrhythmias | Hyperkalemia: peaked T waves, bradycardia, renal failure risk |
| Calcium (CaΒ²βΊ) | 8.5β10.5 mg/dL | Hypocalcemia: Trousseau's sign, tetany, post-thyroidectomy risk | Hypercalcemia: "bones, groans, moans, stones" β cancer, hyperparathyroidism |
| pH (arterial) | 7.35β7.45 | Acidosis: <7.35 β respiratory or metabolic causes | Alkalosis: >7.45 β hyperventilation or HCOββ» excess |

| Creatinine | 0.6β1.2 mg/dL | Low muscle mass; not clinically significant | Renal failure; rises more slowly than BUN |
Clinical Scenario Q&A
These scenarios test application-level thinking β the level the NCLEX targets. Try reasoning through each before reading the answer.
Patient Assessment
1. A patient's SpOβ is 91% on room air. What is the nurse's priority action?
Reposition the patient to improve ventilation (e.g., high Fowler's position), then apply supplemental oxygen as ordered. Normal SpOβ is 95β100%. Below 90% is a clinical emergency. After initial intervention, notify the provider and reassess.
2. A post-op patient's blood pressure drops from 130/80 to 88/54 mmHg over two hours. What does the nurse assess first?
Assess for bleeding β check the surgical site, drains, and urine output. Then assess mental status and skin (pallor, diaphoresis). This presentation suggests hemorrhagic shock. Notify the provider immediately while establishing IV access for fluid resuscitation.
Pharmacology
3. The nurse is about to administer digoxin. What must be assessed before giving the medication?
Apical pulse for one full minute. Digoxin is held if the pulse is below 60 bpm in adults (parameters vary by order). Also check the most recent potassium level β hypokalemia increases digoxin toxicity risk significantly.
4. A patient on warfarin has an INR of 5.2 (therapeutic range 2β3). What is the nurse's priority concern?
Bleeding risk. An INR of 5.2 means the patient's blood takes more than twice the therapeutic time to clot. Assess for active bleeding (gums, urine, stool, bruising). The antidote for warfarin is vitamin K. Notify the provider β dose adjustment or reversal may be indicated.
Infection Control
5. A patient is admitted with suspected tuberculosis. What precautions does the nurse implement?
Airborne precautions immediately: negative-pressure private room, N95 respirator for all staff entering the room (not just a surgical mask), door kept closed. TB is transmitted by airborne nuclei that remain suspended in the air.
6. In what order should a nurse remove PPE after leaving an isolation room?
Gloves first (most contaminated), then gown, then eye protection/face shield, then mask/respirator. Hand hygiene between each step and again after removing all PPE. The goal is never to contaminate your face or clothes with the outer surfaces of the PPE.
Fluid & Electrolytes
7. A patient with heart failure has an order for 0.9% NS at 125 mL/hr. Should the nurse question this order?
Yes. 0.9% NS (isotonic normal saline) expands intravascular volume. In heart failure, the heart is already volume-overloaded. This order warrants clarification β the provider may have intended a fluid restriction or a different fluid type.
8. A patient's potassium is 2.8 mEq/L. What ECG changes would the nurse expect?
Flattened or inverted T waves, presence of U waves, prolonged QT interval. Hypokalemia increases the risk of life-threatening arrhythmias including ventricular fibrillation, especially in patients on digoxin or those with existing cardiac disease.
Nursing Process
9. Which of the following can the RN delegate to unlicensed assistive personnel (UAP)?
Vital sign measurement, feeding a stable patient, ambulating a stable patient, and oral hygiene for a patient without aspiration risk. The RN cannot delegate assessment, teaching, evaluation, or administration of medications β these require nursing judgment.
10. A nurse using SBAR to report a deteriorating patient should include which elements?
Situation (what is happening now), Background (relevant history and medications), Assessment (what the nurse thinks is going on), Recommendation (what the nurse is requesting β e.g., "I need an order for supplemental oxygen and a provider to assess the patient").
Why Active Learning Works for NCLEX Preparation
The NCLEX pass rate for first-time U.S.-educated test-takers is approximately 86%, but the exam is deliberately designed to test at the edge of competence β a student who barely passes nursing school will barely pass the NCLEX. The exam's adaptive algorithm means there's no "safe" topic to rely on: it finds weaknesses and tests them repeatedly.
Retrieval practice addresses the NCLEX challenge directly. Nursing students who study by re-reading notes build recognition memory β they can identify the correct answer when it's presented. Retrieval practice builds recall memory β the ability to generate the correct action in a clinical scenario without cues. The latter is what the NCLEX (and clinical practice) actually requires.
Use this quiz as a recurring self-assessment, not a one-time event. Play it weekly throughout your program. The questions you found easy six weeks ago may reveal surprising gaps now that you've learned more β and those gaps are exactly what to address before the licensing exam.
