Question 1
A 68-year-old patient with a history of chronic heart failure (HFrEF) is admitted with
acute decompensated heart failure. The patient is currently receiving lisinopril,
carvedilol, and furosemide. Which laboratory finding is most critical to assess before
initiating an intravenous infusion of nesiritide?
A. Serum creatinine
B. Serum potassium
C. Serum sodium
D. Serum magnesium
Answer: A. Serum creatinine
Rationale: Nesiritide (recombinant B-type natriuretic peptide) causes vasodilation and
can significantly reduce renal perfusion pressure, potentially worsening renal function.
Before initiating nesiritide, it is essential to assess baseline renal function with serum
creatinine, as patients with pre-existing renal impairment are at higher risk for acute
kidney injury. While potassium, sodium, and magnesium are important to monitor in
heart failure patients, they are not the primary safety parameter required specifically
prior to nesiritide initiation. The package insert and clinical guidelines emphasize renal
function assessment due to the risk of azotemia.
Question 2
,3|Page
A 55-year-old male with type 2 diabetes and hypertension is started on lisinopril. He
returns to the clinic two weeks later with a persistent dry cough and mild
angioedema of the lips. Which medication should the provider switch to as the best
alternative?
A. Amlodipine
B. Losartan
C. Metoprolol
D. Hydrochlorothiazide
Answer: B. Losartan
Rationale: Lisinopril is an ACE inhibitor, and ACE inhibitors are well-known for causing
a dry cough and angioedema due to increased bradykinin levels. Losartan is an
angiotensin II receptor blocker (ARB) that provides similar blood pressure and renal
protective benefits without affecting bradykinin metabolism, making it the preferred
switch. Amlodipine, metoprolol, and HCTZ are antihypertensives but do not offer the
same renoprotective effects as ACE inhibitors or ARBs, especially in diabetic patients.
Question 3
A patient with asthma is prescribed fluticasone/salmeterol (Advair Diskus) for long-
term control. Which instruction is most important for the nurse to include in patient
teaching?
A. Take this medication only during acute asthma attacks
B. Rinse mouth with water after each use
C. Use this medication before exercising to prevent bronchospasm
D. Double the dose if symptoms worsen
Answer: B. Rinse mouth with water after each use
, 4|Page
Rationale: Fluticasone is an inhaled corticosteroid that can cause oral candidiasis
(thrush) and hoarseness. Rinsing the mouth after each use reduces the risk of these side
effects. Advair is a controller medication taken daily, not for acute attacks (that
requires a rescue inhaler like albuterol). It is not a pre-exercise prophylactic agent (that
would be a short-acting beta-agonist or cromolyn). Doubling doses without provider
guidance can increase side effects without providing additional benefit.
Question 4
A 72-year-old patient with heart failure and reduced ejection fraction (HFrEF) is on
digoxin, furosemide, and spironolactone. The patient reports nausea, anorexia, and
seeing yellow halos around lights. What is the nurse's priority action?
A. Administer digoxin immune Fab
B. Administer potassium chloride IV
C. Hold the digoxin and obtain a serum digoxin level
D. Increase the furosemide dose to reduce fluid overload
Answer: C. Hold the digoxin and obtain a serum digoxin level
Rationale: Nausea, anorexia, and yellow-green visual disturbances (xanthopsia) are
classic signs of digoxin toxicity. The priority is to hold the digoxin and obtain a serum
level to confirm toxicity. Digoxin immune Fab is used for severe, life-threatening
toxicity but is not the first step. Potassium supplementation may be needed if
hypokalemia precipitated the toxicity (especially with concurrent furosemide), but the
priority is assessing the level. Increasing furosemide would worsen hypokalemia and
increase toxicity risk.
