QUESTIONS AND DETAILED VERIFIED ANSWERS
FROM ACTUAL EXAMS TEST GRADE A+
1.
A client with heart failure is prescribed furosemide. Which lab value is most
important to monitor?
A. Sodium
B. Potassium
C. Calcium
D. Magnesium
Answer: B. Potassium
Furosemide is a loop diuretic that causes potassium loss, increasing risk for
hypokalemia and cardiac dysrhythmias.
2.
Which assessment finding indicates worsening respiratory distress?
A. Respiratory rate of 18
B. Use of accessory muscles
C. Oxygen saturation of 96%
D. Clear breath sounds
Answer: B. Use of accessory muscles
Accessory muscle use indicates increased work of breathing and respiratory
compromise.
3.
,A client with diabetes has a blood glucose of 55 mg/dL. What is the priority
action?
A. Administer insulin
B. Give 15 g of glucose
C. Start IV fluids
D. Notify provider
Answer: B. Give 15 g of glucose
Hypoglycemia requires immediate treatment with fast-acting carbohydrates.
4.
Which symptom is most consistent with hyperkalemia?
A. Muscle weakness
B. Constipation
C. Hypotension
D. Bradycardia
Answer: A. Muscle weakness
Hyperkalemia disrupts neuromuscular function, leading to weakness and potential
paralysis.
5.
Which intervention is appropriate for a client with increased intracranial pressure
(ICP)?
A. Elevate HOB 30 degrees
B. Flex hips
C. Increase stimuli
D. Encourage coughing
Answer: A. Elevate HOB 30 degrees
Elevating the head promotes venous drainage and reduces ICP.
,6.
Which sign suggests fluid overload?
A. Dry mucous membranes
B. Hypotension
C. Crackles in lungs
D. Decreased weight
Answer: C. Crackles in lungs
Fluid overload leads to pulmonary congestion, causing crackles.
7.
Which diet is appropriate for a client with chronic kidney disease?
A. High protein
B. Low sodium and potassium
C. High potassium
D. High calcium
Answer: B. Low sodium and potassium
CKD clients retain sodium and potassium, requiring restriction.
8.
What is the priority nursing action for a client with chest pain?
A. Administer oxygen
B. Obtain ECG
C. Assess pain
D. Give aspirin
Answer: B. Obtain ECG
An ECG identifies myocardial ischemia or infarction immediately.
, 9.
Which finding indicates effective treatment of pneumonia?
A. Increased WBC
B. Clear breath sounds
C. Fever persists
D. Productive cough increases
Answer: B. Clear breath sounds
Resolution of infection improves lung sounds.
10.
Which electrolyte imbalance causes peaked T waves?
A. Hypokalemia
B. Hyperkalemia
C. Hyponatremia
D. Hypercalcemia
Answer: B. Hyperkalemia
Peaked T waves are a classic ECG sign of elevated potassium.
11.
Which position improves oxygenation in ARDS?
A. Supine
B. Prone
C. Fowler’s
D. Lateral
Answer: B. Prone
Prone positioning improves ventilation-perfusion matching.
