MED-SURG NURSING TEST BANK EXAM LATEST
2026 UPDATE 100 QUESTIONS AND DETAILED
VERIFIED ANSWERS FROM ACTUAL EXAMS TEST
GRADE A+
1.
A nurse is caring for a patient with heart failure. Which assessment finding
requires immediate intervention?
A. Weight gain of 1 lb in 24 hours
B. Crackles in lung bases
C. Blood pressure 130/80 mmHg
D. Heart rate 88 bpm
Answer: B
Rationale: Crackles indicate pulmonary edema, a sign of worsening heart failure
requiring immediate action.
2.
Which electrolyte imbalance is most associated with cardiac dysrhythmias?
A. Hypercalcemia
B. Hypokalemia
C. Hypernatremia
D. Hypomagnesemia
Answer: B
Rationale: Low potassium levels significantly affect cardiac conduction, leading to
dysrhythmias.
,3.
A patient with COPD is receiving oxygen therapy. Which finding indicates oxygen
toxicity?
A. Restlessness
B. Dyspnea
C. Nonproductive cough
D. Hypertension
Answer: C
Rationale: Oxygen toxicity often presents with a nonproductive cough and chest
discomfort.
4.
Which intervention is priority for a patient with suspected stroke?
A. Administer aspirin
B. Check blood glucose
C. Start IV fluids
D. Elevate head of bed
Answer: B
Rationale: Hypoglycemia can mimic stroke symptoms and must be ruled out first.
5.
A patient develops sudden chest pain and dyspnea. What is the priority action?
A. Obtain ECG
B. Administer morphine
C. Check oxygen saturation
D. Start IV fluids
Answer: C
Rationale: Airway and oxygenation are the first priorities in acute distress.
,6.
Which finding is expected in dehydration?
A. Bounding pulse
B. Moist mucous membranes
C. Increased urine output
D. Tachycardia
Answer: D
Rationale: Tachycardia compensates for decreased circulating volume.
7.
Which lab value indicates kidney dysfunction?
A. Creatinine 2.5 mg/dL
B. Hemoglobin 13 g/dL
C. Sodium 140 mEq/L
D. Potassium 4.0 mEq/L
Answer: A
Rationale: Elevated creatinine reflects impaired renal function.
8.
A patient with diabetes has a blood glucose of 50 mg/dL. What is the priority
intervention?
A. Administer insulin
B. Give 15 g of glucose
C. Start IV fluids
D. Call provider
, Answer: B
Rationale: Immediate treatment of hypoglycemia is oral glucose if patient is
conscious.
9.
Which symptom is most concerning in a patient with pneumonia?
A. Fever
B. Productive cough
C. Confusion
D. Fatigue
Answer: C
Rationale: Confusion indicates hypoxia, especially in older adults.
10.
Which position improves oxygenation in a patient with respiratory distress?
A. Supine
B. Trendelenburg
C. High Fowler’s
D. Side-lying
Answer: C
Rationale: High Fowler’s maximizes lung expansion.
11.
A patient with liver disease is at risk for which complication?
A. Hypercalcemia
B. Bleeding
C. Hypertension
D. Bradycardia
