NLN NEX EXAM 2026/2027 | PRACTICE QUESTIONS, VERIFIED ANSWERS &
DETAILED RATIONALES | COMPLETE STUDY GUIDE
OVERVIEW
• This comprehensive study guide contains 200+ verified practice questions with
detailed rationales designed to simulate the actual NLN NEX exam format and
difficulty level, helping you identify knowledge gaps and build test-taking
confidence.
• Study strategically by working through questions in timed blocks, reviewing
rationales for both correct and incorrect answers, and tracking your performance
across all tested domains to prioritize areas needing reinforcement.
QUESTIONS
1. A patient with chronic kidney disease has a potassium level of 6.8 mEq/L.
Which action should the nurse take FIRST?
A) Administer a diuretic
B) Insert an indwelling catheter
C) Notify the healthcare provider
D) Place the patient on a cardiac monitor
E) Restrict fluid intake
✓ CORRECT ANSWER: D) Place the patient on a cardiac monitor
,RATIONALE: Elevated potassium (hyperkalemia) at 6.8 mEq/L (normal: 3.5–5.0
mEq/L) poses an immediate cardiac risk due to its effect on myocardial
repolarization, potentially causing life-threatening dysrhythmias. Cardiac
monitoring is the priority intervention to detect changes. While notifying the
provider is important, monitoring is the immediate nursing action. Diuretics and
fluid restriction require provider orders and are secondary interventions.
2. Which assessment finding indicates the greatest risk for pressure ulcer
development in a bedridden patient?
A) Intact skin over bony prominences
B) Serum albumin level of 2.8 g/dL
C) Ability to reposition self every 2 hours
D) Adequate nutritional intake
E) Capillary refill time of 3 seconds
✓ CORRECT ANSWER: B) Serum albumin level of 2.8 g/dL
RATIONALE: Low serum albumin (normal: 3.5–5.0 g/dL) indicates protein
malnutrition, which directly impacts skin integrity and the body's ability to repair
damaged tissues. This is a major risk factor for pressure ulcer development. While
intact skin and adequate nutrition are protective factors, ability to reposition, and
normal capillary refill indicate good circulation, low albumin demonstrates a
systemic nutritional deficiency that increases vulnerability to pressure ulcers.
3. A pregnant client at 28 weeks gestation presents with a blood pressure of
160/110 mmHg, proteinuria of 3+, and severe headache. What is the priority
nursing diagnosis?
A) Deficient fluid volume
B) Risk for maternal injury
C) Ineffective health maintenance
,D) Anxiety
E) Pain
✓ CORRECT ANSWER: B) Risk for maternal injury
RATIONALE: The clinical presentation of severe hypertension (160/110 mmHg),
proteinuria (3+), and severe headache are classic signs of severe
preeclampsia/eclampsia, which can progress to eclamptic seizures or cerebral
hemorrhage. Maternal safety is the priority. While fluid volume status may need
monitoring, pain management is needed, and anxiety may be present, the
immediate threat is maternal seizure or stroke, making prevention of injury the top
priority.
4. A client receiving chemotherapy for breast cancer reports severe nausea
and vomiting. Which antiemetic medication is MOST effective when given
before chemotherapy?
A) Ondansetron (Zofran)
B) Promethazine (Phenergan)
C) Metoclopramide (Reglan)
D) Diphenhydramine (Benadryl)
E) Ginger supplements
✓ CORRECT ANSWER: A) Ondansetron (Zofran)
RATIONALE: Ondansetron is a 5-HT3 receptor antagonist specifically approved for
chemotherapy-induced nausea and vomiting (CINV) and is most effective when
given as premedication before chemotherapy administration. It has superior
efficacy compared to older antiemetics. While other medications may provide some
relief, ondansetron is the gold standard for CINV prevention and is recommended
by NCCN guidelines. Ginger supplements lack sufficient evidence for CINV.
, 5. A client with acute myocardial infarction is prescribed aspirin, metoprolol,
lisinopril, and atorvastatin. What is the primary action of metoprolol in this
situation?
A) Reduces cholesterol levels
B) Lowers blood pressure and decreases myocardial oxygen demand
C) Prevents blood clots
D) Reduces inflammation
E) Increases heart contractility
✓ CORRECT ANSWER: B) Lowers blood pressure and decreases myocardial
oxygen demand
RATIONALE: Metoprolol is a beta-blocker that decreases heart rate, contractility,
and blood pressure, thereby reducing myocardial oxygen demand—critical after MI
to limit infarct size and reduce mortality risk. Atorvastatin (statin) reduces
cholesterol, aspirin prevents clots, lisinopril (ACE inhibitor) lowers BP and protects
the heart post-MI. Metoprolol's specific cardioprotective benefit is reducing
workload on the damaged myocardium.
6. A nurse is assessing a client 24 hours post-appendectomy. Which finding
requires immediate intervention?
A) Hypoactive bowel sounds
B) Slight purulent drainage from the incision
C) Abdominal distension with severe pain and rigid abdomen
D) Decreased urine output
E) Pain at incision site
✓ CORRECT ANSWER: C) Abdominal distension with severe pain and rigid
abdomen
