DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+
1. A nurse is caring for a client with heart failure who is prescribed
furosemide. Which finding requires immediate intervention?
A. Potassium level 3.0 mEq/L
B. Urine output of 400 mL in 8 hours
C. Blood pressure 110/70 mmHg
D. Weight loss of 0.5 kg in 24 hours
Answer: A
Rationale: Furosemide is a loop diuretic that causes potassium loss. A potassium
level of 3.0 mEq/L indicates hypokalemia, which can lead to life-threatening
dysrhythmias.
2. A client with COPD is receiving oxygen at 4 L/min via nasal cannula. The
nurse should prioritize which action?
A. Encourage coughing and deep breathing
B. Monitor for oxygen-induced hypoventilation
C. Switch to a non-rebreather mask
D. Increase oxygen to 6 L/min
Answer: B
Rationale: COPD clients are at risk for CO₂ retention. Oxygen therapy must be
carefully monitored to prevent hypoventilation.
3. A postoperative client suddenly reports chest pain and shortness of breath.
What is the nurse’s first action?
A. Obtain a stat ECG
B. Elevate head of bed and apply oxygen
,C. Administer pain medication
D. Notify the provider
Answer: B
Rationale: Airway and breathing come first. Oxygen and positioning are
immediate priorities before diagnostics.
4. Which lab result should the nurse report immediately in a client taking
warfarin?
A. INR 2.5
B. INR 3.8
C. Platelets 150,000
D. Hemoglobin 13 g/dL
Answer: B
Rationale: INR above therapeutic range increases bleeding risk and requires
intervention.
5. A client with diabetes has a blood glucose of 52 mg/dL. What should the
nurse administer?
A. IV insulin
B. 15 g oral glucose
C. Long-acting insulin
D. Protein snack only
Answer: B
Rationale: Immediate treatment of hypoglycemia involves fast-acting
carbohydrates.
6. A nurse is assessing dehydration in an elderly client. Which finding is most
concerning?
A. Dry mucous membranes
B. Poor skin turgor
, C. Confusion and lethargy
D. Decreased urine output
Answer: C
Rationale: Neurological changes indicate severe dehydration and possible
hypovolemic shock.
7. A client with pneumonia has thick secretions. Which intervention is best?
A. Restrict fluids
B. Encourage incentive spirometry
C. Maintain supine position
D. Limit coughing
Answer: B
Rationale: Incentive spirometry promotes lung expansion and secretion
mobilization.
8. Which symptom indicates digoxin toxicity?
A. Hypertension
B. Bradycardia and nausea
C. Weight gain
D. Hyperactivity
Answer: B
Rationale: Digoxin toxicity commonly presents with bradycardia, nausea, and
visual disturbances.
9. A nurse is caring for a client in labor. Which finding requires immediate
attention?
A. Contractions every 5 minutes
B. Fetal heart rate 90 bpm
C. Cervical dilation 5 cm
D. Rupture of membranes
