This examination is designed to strengthen clinical reasoning, prioritization, patient safety
awareness, and evidence-based management of complex medical-surgical conditions
encountered in acute care settings.
, PRACTICE QUESTIONS
Question One
A medical-surgical nurse is caring for a patient admitted with acute heart failure. Which
assessment finding requires immediate intervention?
A. Oxygen saturation of 86% on room air
B. Mild ankle edema
C. Heart rate of 88 beats/minute
D. Blood pressure of 138/84 mmHg
Correct Answer: A. Oxygen saturation of 86% on room air
Rationale: An oxygen saturation of 86% indicates significant hypoxemia and impaired
oxygen delivery to tissues. Airway and breathing are priority considerations according to
nursing prioritization principles. Prompt intervention can prevent respiratory failure and
further deterioration.
Question Two
A nurse is assessing a patient with suspected deep vein thrombosis. Which finding is most
consistent with this condition?
A. Unilateral calf swelling and tenderness
B. Bilateral hearing loss
C. Epigastric pain
D. Productive cough
Correct Answer: A. Unilateral calf swelling and tenderness
Rationale: Deep vein thrombosis commonly presents with unilateral swelling, warmth,
redness, and tenderness of the affected extremity. Early identification is critical because
pulmonary embolism is a potentially life-threatening complication.
, Question Three
A nurse is caring for a patient with type 2 diabetes mellitus. Which laboratory value best
evaluates long-term glycemic control?
A. Hemoglobin A1c
B. White Blood Cell Count
C. Serum Potassium
D. Troponin Level
Correct Answer: A. Hemoglobin A1c
Rationale: Hemoglobin A1c reflects average blood glucose levels over approximately two to
three months and is a key indicator of diabetes management effectiveness. It assists
clinicians in evaluating treatment success and modifying care plans.
Question Four
A nurse is caring for a postoperative patient. Which assessment finding may indicate a
developing pulmonary embolism?
A. Sudden shortness of breath and chest pain
B. Mild incisional discomfort
C. Decreased appetite
D. Constipation
Correct Answer: A. Sudden shortness of breath and chest pain
Rationale: Pulmonary embolism frequently presents with sudden dyspnea, chest pain,
tachycardia, and hypoxemia. Immediate recognition and intervention are necessary
because pulmonary embolism can rapidly become fatal.
Question Five
A nurse is assessing a patient with chronic obstructive pulmonary disease. Which
intervention is most effective in slowing disease progression?
A. Smoking cessation
