, NUR 242 Med-Surg 3 Exam 2026 – 60 Questions with Answers &
Explanations
1. A client with heart failure is prescribed furosemide. Which finding indicates the
medication is effective?
a) 3+ pitting edema in the ankles
b) Weight loss of 2 kg in 3 days
c) Crackles heard in lung bases
d) Serum potassium level of 2.9 mEq/L
Answer: b) Weight loss of 2 kg in 3 days
Explanation: Effective diuretic therapy in heart failure is indicated by reduced fluid retention,
demonstrated by weight loss. Hypokalemia (K+ 2.9) is a complication, not effectiveness.
2. A nurse reviews the ECG strip of a client. What rhythm is shown below?
a) Atrial fibrillation
b) Ventricular tachycardia
c) ST-elevation myocardial infarction (STEMI)
d) First-degree AV block
Answer: c) ST-elevation myocardial infarction (STEMI)
Explanation: ST elevations in leads V1–V4 indicate acute anterior wall MI, requiring
emergency reperfusion.
3. A client with pneumonia is placed on oxygen therapy. The nurse should titrate oxygen to
maintain which target SpO₂ in accordance with 2025 guidelines?
a) 85–88%
b) 88–92%
c) 94–98%
d) 100% continuously
, Answer: c) 94–98%
Explanation: Current guidelines recommend maintaining oxygen saturation between 94–98%
for most acutely ill adults. Higher O₂ can be harmful.
4. A nurse is caring for a diabetic patient with blood glucose of 45 mg/dL. What is the
priority action?
a) Give 50 mL of D50 IV push
b) Recheck blood glucose in 15 minutes
c) Administer long-acting insulin
d) Encourage ambulation
Answer: a) Give 50 mL of D50 IV push
Explanation: Severe hypoglycemia (<50 mg/dL) with risk of seizures or coma requires
immediate IV dextrose if IV access is present.
5. A patient is prescribed warfarin. Which laboratory value is most important to monitor?
a) Hemoglobin
b) INR
c) Platelet count
d) aPTT
Answer: b) INR
Explanation: INR is used to monitor therapeutic effect of warfarin. Target INR usually 2–3.
6. A nurse is administering digoxin. Which finding indicates digoxin toxicity?
a) Heart rate 88 bpm
b) Blurred vision with yellow halos
c) Blood pressure 138/84 mmHg
d) Potassium level 4.2 mEq/L
Answer: b) Blurred vision with yellow halos
Explanation: Classic sign of digoxin toxicity includes visual disturbances (yellow-green halos),
along with bradycardia and arrhythmias.
