PN Adult Medical-Surgical Nursing Practice
Questions (200 NCLEX-Style QUESTIONS
AND ANSWERS with Rationales) 2026
UPDATE.
INTRODUCTION
Adult Medical-Surgical Nursing is one of the most critical and challenging areas in PN
licensure exams, requiring strong clinical judgment, prioritization skills, and a deep
understanding of patient care concepts. This comprehensive collection of 200 high-quality PN
Med-Surg practice questions is designed to help you build confidence and master exam-ready
thinking through realistic, NCLEX-style scenarios.
Each question is carefully structured with detailed clinical situations, evidence-based answers,
and clear rationales to strengthen your understanding and improve retention. The questions
cover essential topics such as cardiovascular disorders, respiratory conditions, renal function,
endocrine imbalances, fluid and electrolyte management, and postoperative care.
1.
A nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is
receiving oxygen therapy via nasal cannula at 4 L/min. Which assessment finding requires
immediate intervention by the nurse?
A. Slight increase in respiratory rate from baseline
B. Dry mucous membranes and mild thirst
C. Decreased level of consciousness and drowsiness
D. Occasional productive cough with clear sputum
Rationale: COPD clients rely on hypoxic drive; excessive oxygen can suppress respiratory
drive, causing CO₂ retention and decreased consciousness.
2.
,A client with a history of heart failure reports sudden weight gain of 2.5 kg (5.5 lb) over three
days and increasing shortness of breath when lying flat. What is the nurse’s priority action?
A. Encourage increased oral fluid intake
B. Document findings and reassess in 24 hours
C. Notify the healthcare provider immediately
D. Place the client in a supine position for comfort
Rationale: Rapid weight gain and orthopnea indicate fluid overload and worsening heart
failure requiring urgent medical intervention.
3.
A nurse is reviewing laboratory results for a client with chronic kidney disease. Which finding
should the nurse report to the provider immediately due to risk of life-threatening complications?
A. Hemoglobin level of 10 g/dL
B. Serum sodium level of 136 mEq/L
C. Serum potassium level of 6.4 mEq/L
D. Blood urea nitrogen level of 28 mg/dL
Rationale: Severe hyperkalemia can cause fatal cardiac arrhythmias and requires immediate
treatment.
4.
A client with type 1 diabetes mellitus becomes pale, diaphoretic, and shaky approximately two
hours after receiving insulin. What is the nurse’s priority intervention?
A. Administer additional insulin as prescribed
B. Encourage the client to drink water
C. Check the client’s blood glucose level immediately
D. Notify the healthcare provider before taking action
Rationale: These are classic signs of hypoglycemia; confirmation with blood glucose guides
appropriate treatment.
5.
,A postoperative client suddenly develops shortness of breath, chest pain, and tachycardia. Which
complication should the nurse suspect first based on these findings?
A. Atelectasis
B. Pneumonia
C. Pulmonary embolism
D. Myocardial infarction
Rationale: Sudden onset of these symptoms strongly suggests pulmonary embolism, a life-
threatening emergency.
6.
A nurse is caring for a client receiving warfarin therapy for atrial fibrillation. Which laboratory
value indicates that the medication is within therapeutic range?
A. Platelet count of 150,000/mm³
B. Hemoglobin level of 13 g/dL
C. INR of 2.5
D. White blood cell count of 7,000/mm³
Rationale: Therapeutic INR for most conditions is between 2.0 and 3.0.
7.
A client with pneumonia is admitted to the medical unit. Which assessment finding is most
consistent with this diagnosis and requires ongoing monitoring?
A. Decreased heart rate and cool extremities
B. Crackles heard in the lower lung fields bilaterally
C. Hyperactive bowel sounds and abdominal distention
D. Increased appetite and weight gain
Rationale: Crackles indicate fluid accumulation in alveoli, common in pneumonia.
8.
A nurse is teaching a client newly diagnosed with hypertension about dietary modifications.
Which statement by the client indicates correct understanding of the teaching?
, A. “I will increase my intake of processed foods daily.”
B. “I should avoid foods that contain potassium.”
C. “I will reduce my salt intake and choose fresh foods instead.”
D. “I can continue adding salt to food if I exercise regularly.”
Rationale: Reducing sodium intake helps manage blood pressure effectively.
9.
A client presents to the emergency department with chest pain that is not relieved by rest or
nitroglycerin. What is the nurse’s priority initial intervention?
A. Provide the client with food and fluids
B. Administer supplemental oxygen as prescribed
C. Encourage the client to ambulate
D. Reassure the client and delay further action
Rationale: Oxygen improves myocardial oxygenation and is a priority in suspected cardiac
events.
10.
A nurse is assessing a client with hypokalemia. Which clinical manifestation should the nurse
expect to observe during the assessment?
A. Increased muscle strength and reflexes
B. Muscle weakness and possible cardiac dysrhythmias
C. Hypertension and bounding pulse
D. Severe diarrhea and abdominal cramping
Rationale: Low potassium affects muscle and cardiac function, leading to weakness and
arrhythmias.
11.
A client scheduled for surgery is instructed to remain NPO for at least eight hours prior to the
procedure. What is the primary reason for this instruction?
A. To reduce postoperative pain
B. To improve digestion after surgery
