1. A nurse is caring for a patient with heart failure
who is receiving furosemide. Which laboratory value
is most important to monitor?
A. Serum potassium
B. Serum sodium
C. Serum calcium
D. Serum magnesium
A. Serum potassium
Furosemide is a loop diuretic that causes
,significant potassium loss via the urine.
Hypokalemia increases the risk of cardiac
dysrhythmias, especially in patients with heart
failure who may also be on digoxin.
2. A patient with chronic kidney disease has a serum
creatinine of 4.2 mg/dL and a GFR of 18 mL/min.
Which stage of chronic kidney disease does this
represent?
A. Stage 2
B. Stage 3
C. Stage 4
D. Stage 5
C. Stage 4
Stage 4 CKD is defined by a GFR of 15–29 mL/min.
Stage 5 is <15 mL/min or dialysis. Stage 3 is 30–59,
and Stage 2 is 60–89.
3. A patient with COPD is prescribed oxygen at 2
L/min via nasal cannula. What is the primary
rationale for using a low flow rate?
,A. To prevent oxygen toxicity
B. To avoid depressing the hypoxic drive
C. To reduce drying of nasal mucosa
D. To maintain adequate humidification
B. To avoid depressing the hypoxic drive
COPD patients often have chronic hypercapnia, so
their primary respiratory drive is hypoxia. High-
flow oxygen can blunt this drive, leading to CO2
retention and respiratory acidosis.
4. A nurse is assessing a patient with pneumonia.
Which finding indicates a complication requiring
immediate intervention?
A. Productive cough with yellow sputum
B. Fever of 101.2°F
C. Sudden onset of severe pleuritic chest pain and
dyspnea
D. Crackles in the lower lung bases
C. Sudden onset of severe pleuritic chest pain and
dyspnea
This may indicate a pneumothorax or pulmonary
, embolism, both of which are life-threatening
complications of pneumonia. Immediate
intervention is required.
5. A patient with asthma is using a metered-dose
inhaler (MDI) with a spacer. The nurse teaches the
patient to hold the breath for how many seconds
after each puff?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 30 seconds
B. 10 seconds
Holding the breath for 10 seconds allows the
medication to deposit deep in the airways. Less
than 5 seconds is ineffective; more than 15 seconds
is not necessary.
6. A patient with hypertension is prescribed
lisinopril. Which adverse effect should the nurse
teach the patient to report immediately?
