MED-SURG TEST BANK EXAM LATEST 2026 UPDATE
100 QUESTIONS AND DETAILED VERIFIED ANSWERS
FROM ACTUAL EXAMS TEST GRADE A+
1. A patient with COPD is receiving oxygen therapy. Which is the best oxygen
delivery method?
A. Non-rebreather mask at 15 L/min
B. Nasal cannula at 1–2 L/min
C. Simple face mask at 10 L/min
D. Venturi mask at 12 L/min
ANSWER: B
Rationale: COPD patients require low-flow oxygen to prevent CO₂ retention and
hypoventilation.
2. A postoperative patient suddenly develops chest pain and dyspnea. What is
the priority action?
A. Administer pain medication
B. Encourage deep breathing
C. Assess oxygen saturation
D. Check surgical dressing
ANSWER: C
Rationale: Airway and oxygenation are priority using ABCs.
3. Which finding indicates hypoglycemia?
,A. Fruity breath odor
B. Sweating and tremors
C. Deep rapid respirations
D. Polyuria
ANSWER: B
Rationale: Adrenergic symptoms like sweating and tremors indicate hypoglycemia.
4. A patient with heart failure should be positioned:
A. Supine
B. Trendelenburg
C. High Fowler’s
D. Prone
ANSWER: C
Rationale: High Fowler’s reduces preload and improves breathing.
5. Which electrolyte imbalance causes tall peaked T waves?
A. Hypokalemia
B. Hyperkalemia
C. Hypocalcemia
D. Hypernatremia
ANSWER: B
Rationale: Hyperkalemia affects cardiac conduction producing peaked T waves.
6. Priority intervention for active seizure is:
A. Restrain patient
B. Insert oral airway
,C. Protect airway and prevent injury
D. Give oral fluids
ANSWER: C
Rationale: Safety and airway protection are priorities during seizures.
7. A sign of increased intracranial pressure (ICP) is:
A. Bradycardia
B. Hypotension
C. Tachycardia
D. Fever only
ANSWER: A
Rationale: Cushing’s triad includes bradycardia in increased ICP.
8. Which lab indicates renal failure?
A. Low creatinine
B. Increased BUN
C. Low potassium
D. Low sodium
ANSWER: B
Rationale: BUN increases when renal function declines.
9. First sign of shock is usually:
A. Hypotension
B. Tachycardia
C. Bradycardia
D. Cyanosis
, ANSWER: B
Rationale: Tachycardia compensates early in shock.
10. Priority nursing action for GI bleeding is:
A. Give antacids
B. Prepare for endoscopy
C. Monitor vital signs
D. Offer oral fluids
ANSWER: C
Rationale: Hemodynamic stability is priority.
11. Which is a classic sign of appendicitis?
A. Left lower quadrant pain
B. Right lower quadrant pain
C. Epigastric pain only
D. Flank pain
ANSWER: B
Rationale: Appendicitis localizes to RLQ (McBurney’s point).
12. Insulin should NOT be given if:
A. Blood glucose is 180 mg/dL
B. Patient is eating
C. Patient is NPO without dextrose plan
D. Blood pressure is high
ANSWER: C
Rationale: Risk of hypoglycemia if no glucose intake.
