Med-Surg NCLEX Practice Questions: 10 High-Yield Scenarios
Share
Medical-surgical nursing is not one chapter. It is where airway, perfusion, medications, labs and priority collide.
Work these ten med-surg NCLEX practice questions before reading the rationale. The goal is not to recognize a fact. It is to make the safest next decision.
Respiratory and cardiac
1. Post-thyroidectomy stridor
A client two hours after thyroidectomy develops inspiratory stridor. Which finding has priority?
Answer: The stridor itself. It signals upper-airway obstruction. Stay with the client, activate emergency support and prepare for airway intervention.
2. Heart failure with pink frothy sputum
A client with heart failure suddenly becomes severely dyspnoeic and coughs pink, frothy sputum. What should the nurse do first?
Answer: Position upright and support oxygenation while escalating care. The pattern suggests acute pulmonary oedema and impaired gas exchange.
3. Chest tube bubbling
Continuous bubbling appears in the water-seal chamber of a chest-drainage system. What does the nurse suspect?
Answer: An air leak. Check the client and trace the tubing and connections according to policy. Intermittent bubbling can be expected early with air removal; continuous bubbling requires investigation.

Endocrine and electrolytes
4. DKA with low potassium
A client with diabetic ketoacidosis has a potassium of 3.2 mEq/L and an insulin infusion is prescribed. What should the nurse question first?
Answer: Starting insulin before the potassium plan is addressed. Insulin moves potassium into cells and can worsen hypokalaemia.
5. Hyperkalaemia with peaked T waves
A client has potassium 6.4 mEq/L and peaked T waves. Which problem has priority?
Answer: Cardiac instability. Place the client on continuous monitoring and prepare to carry out urgent prescribed treatment.
6. SIADH and confusion
A client with SIADH develops headache and increasing confusion. Which complication is most concerning?
Answer: Worsening hyponatraemia with cerebral effects. Institute seizure precautions and report the neurologic change promptly.
Neurologic, renal and gastrointestinal
7. Stroke and swallowing
A client admitted with an acute stroke asks for water. What is the safest response?
Answer: Keep the client NPO until swallowing has been screened according to protocol. Dysphagia creates aspiration risk.
8. Acute kidney injury medication
Which medication order should the nurse question for a client with acute kidney injury and rising potassium?
Answer: A potassium supplement. The kidneys may not clear potassium effectively, increasing dysrhythmia risk.
9. Suspected upper GI bleed
A client has coffee-ground emesis, heart rate 122/min and blood pressure 86/52 mmHg. What is the priority?
Answer: Circulation and rapid response to possible shock. Protect the airway as needed, establish or maintain large-bore access and initiate ordered resuscitation while escalating care.
Post-operative care
10. Sudden restlessness after surgery
An older adult becomes newly restless and confused after surgery. What should the nurse assess first?
Answer: Oxygenation and vital signs. Restlessness can be an early sign of hypoxia, bleeding or another acute deterioration; do not assume it is age or medication.
The pattern behind all ten answers
- New and unexpected beats chronic and expected.
- Airway, breathing, circulation and immediate safety narrow the field.
- Trends and symptoms matter more than an isolated label.
- Assess when the problem is unclear; act when the emergency is already established.
- Never let a routine task delay a deteriorating client.
How to review a missed med-surg question
Do not copy the whole rationale into a notebook. First label the miss: content gap, priority error, safety error or careless reading. Then write one rule you can reuse, such as “new stridor after neck surgery is an airway emergency” or “symptomatic potassium changes outrank a routine task.”
Redo the question without notes the next day and explain why every wrong option is less safe. That second pass turns one scenario into a decision pattern you can recognize when the diagnosis, age or setting changes.

Review the complete content system →Frequently asked questions
Is med-surg a large part of the NCLEX?
Med-surg concepts appear across several Client Needs categories, especially physiological adaptation, reduction of risk and pharmacological therapies.
How should I study med-surg for the NCLEX?
Study by patterns: expected versus unexpected, stable versus unstable, body-system priorities and medication safety. Then practise mixed questions.
Are NCLEX med-surg questions mostly memorization?
No. The official test plan emphasizes application and clinical judgment. You need enough content to recognize the problem and enough practice to choose the next safe action.
You've got this. Ten questions are a start; the pattern is what you carry into the exam.
