NUR 209 MEDICAL SURGICAL NURSING
II EXAM 2 V2 QUESTIONS WITH
CORRECT ANSWERS (LATEST 2026 /
2027), (A+ GUARANTEE).
1. A patient with chronic heart failure is receiving digoxin and furosemide. The nurse notes
the patient reports seeing yellow-green halos around lights. Which action should the nurse
take first?
A. Document the finding as a common side effect of diuretic therapy.
B. Administer the next scheduled dose of digoxin.
C. Assess the patient’s serum potassium and digoxin levels.
D. Perform a visual acuity test using a Snellen chart.
Answer: C
Conceptual Explanation: Yellow-green halos are a classic sign of digoxin toxicity, which is
often precipitated by hypokalemia caused by loop diuretics like furosemide. Serum levels
must be checked immediately.
,2. A client is admitted with an exacerbation of COPD. The arterial blood gas (ABG) results are:
pH 7.30, PaCO2 58 mmHg, HCO3 30 mEq/L, and PaO2 60 mmHg. How should the nurse
interpret these results?
A. Compensated metabolic alkalosis
B. Uncompensated respiratory acidosis
C. Partially compensated respiratory acidosis
D. Fully compensated respiratory acidosis
Answer: C
Conceptual Explanation: The pH is low (acidosis), the PaCO2 is high (respiratory cause),
and the HCO3 is high (indicating the kidneys are attempting to compensate), but the pH has
not returned to normal, making it partially compensated.
3. The nurse is caring for a patient who underwent a thyroidectomy 6 hours ago. The patient
reports tingling in the fingers and around the mouth. Which medication should the nurse
have readily available?
A. Calcium gluconate
B. Levothyroxine
C. Potassium chloride
D. Sodium nitroprusside
Answer: A
, Conceptual Explanation: Tingling in the extremities (paresthesia) and circumoral
numbness are signs of hypocalcemia, a potential complication if the parathyroid glands are
accidentally damaged or removed during a thyroidectomy.
4. A patient with a history of atrial fibrillation is prescribed warfarin. Which laboratory result
indicates that the dosage is therapeutic?
A. Hemoglobin of 14 g/dL
B. PTT of 60 to 80 seconds
C. Platelet count of 150,000/mm3
D. INR between 2.0 and 3.0
Answer: D
Conceptual Explanation: For patients with atrial fibrillation, the therapeutic INR range is
typically 2.0 to 3.0. PTT is used to monitor heparin therapy, not warfarin.
5. A nurse is monitoring a patient with a chest tube. The nurse notes continuous bubbling in
the water-seal chamber. What does this finding indicate?
A. The system is functioning correctly.
B. There is an air leak in the system.
C. The patient has a resolving pneumothorax.
D. The suction pressure is too high.
Answer: B
