1. A patient presents with a persistent cough, night sweats, and a low-grade fever.
Which diagnostic test is the priority to confirm a suspected diagnosis of pulmonary
tuberculosis?
,A. Chest X-ray
B. Sputum culture for acid-fast bacilli
C. Tuberculin skin test
D. Bronchoscopy
🟢 B. Sputum culture for acid-fast bacilli
🔴 Explanation: While a chest X-ray and skin test provide supportive evidence, the
sputum culture is the gold standard for confirming an active Mycobacterium tuberculosis
infection.
2. A nurse is caring for a patient in the early stages of hypovolemic shock. Which
clinical manifestation should the nurse expect to observe first?
A. Hypotension
B. Decreased urine output
C. Tachycardia
D. Lethargy
🟢 C. Tachycardia
🔴 Explanation: Tachycardia is an early compensatory mechanism triggered by the
sympathetic nervous system to maintain cardiac output when blood volume decreases.
, 3. Which dietary instruction is most appropriate for a patient newly diagnosed with
chronic kidney disease (CKD)?
A. Increase intake of potassium-rich foods
B. Limit protein intake to reduce nitrogenous waste
C. Use salt substitutes to manage sodium levels
D. Increase fluid intake to 3 liters per day
🟢 B. Limit protein intake to reduce nitrogenous waste
🔴 Explanation: Restricting dietary protein helps slow the progression of CKD by reducing
the accumulation of urea and other nitrogenous wastes that the kidneys cannot effectively
clear.
4. A patient with type 1 diabetes is found unconscious with a blood glucose level of 45
mg/dL. Which action should the nurse take immediately?
A. Administer 15g of simple carbohydrates orally
B. Administer 1 mg of glucagon subcutaneously
C. Start an insulin drip at 0.1 units/kg/hr
D. Re-check the blood glucose level in 15 minutes
🟢 B. Administer 1 mg of glucagon subcutaneously
🔴 Explanation: Because the patient is unconscious and cannot safely swallow, glucagon
, or intravenous dextrose is required to rapidly elevate blood glucose.
5. When assessing a patient with a suspected deep vein thrombosis (DVT) in the right
leg, which finding is most characteristic?
A. Bilateral pedal edema
B. Cool, pale skin on the affected extremity
C. Unilateral calf swelling and tenderness
D. Absence of a dorsalis pedis pulse
🟢 C. Unilateral calf swelling and tenderness
🔴 Explanation: DVT typically presents as unilateral localized pain, edema, and warmth
due to venous obstruction and inflammation.
6. Which nursing intervention is a priority for a patient during the immediate
postoperative period following a total thyroidectomy?
A. Assessing for Chvostek's sign
B. Encouraging vigorous coughing and deep breathing
C. Monitoring for signs of airway obstruction
D. Administering oral thyroid hormone replacement
