1. A 68-year-old patient with a history of heart failure and chronic obstructive pulmonary disease
(COPD) is prescribed a non-selective beta-blocker. Which assessment finding requires
immediate intervention by the advanced practice nurse?
A. Heart rate of 62 bpm
B. Wheezing and increased airway resistance
C. Blood pressure of 130/80 mmHg
D. Peripheral edema of 1+
Answer: B
Rationale: Non-selective beta-blockers block both beta-1 and beta-2 receptors; blocking beta-2
receptors in the lungs causes bronchoconstriction, which is contraindicated in patients with
COPD. Option A, C, and D are within acceptable clinical parameters or expected findings for
heart failure management, whereas bronchospasm is a life-threatening adverse effect of non-
selective blockade.
, CORRECT ANSWER : B
2. A patient receiving lisinopril for hypertension develops a dry, persistent cough. Which
mechanism explains this adverse effect?
A. Direct irritation of the bronchial mucosa
B. Increased pulmonary capillary permeability
C. Accumulation of bradykinin in the lungs
D. Inhibition of prostaglandin synthesis
Answer: C
Rationale: ACE inhibitors prevent the degradation of bradykinin, a vasodilator peptide that
accumulates in the respiratory tract and triggers a cough reflex. Option A is incorrect as the
cough is systemic/chemical in nature, not mechanical irritation; B is incorrect as this is not a
primary mechanism of ACEi; and D is related to NSAID mechanisms, not ACE inhibitors.
CORRECT ANSWER : C
3. Which medication is most appropriate for a patient with acute decompensated heart failure who
exhibits fluid overload and significant renal impairment?
A. Hydrochlorothiazide
B. Spironolactone
C. Furosemide
D. Metolazone
Answer: C
Rationale: Furosemide is a loop diuretic capable of maintaining efficacy even when the
glomerular filtration rate (GFR) is significantly reduced, making it the agent of choice for acute
fluid volume overload. Thiazides like hydrochlorothiazide lose effectiveness as renal function
declines; spironolactone is a potassium-sparing agent with weak diuretic properties; and
metolazone is usually used as an adjunct, not as a primary initial treatment.
CORRECT ANSWER : C
4. A patient is prescribed warfarin. Which patient statement indicates a need for further education
regarding drug-drug interactions?
, A. "I will maintain a consistent intake of green leafy vegetables."
B. "I will start taking St. John’s Wort to help with my mood."
C. "I will use an electric razor to shave."
D. "I will report any signs of unusual bruising to my provider."
Answer: B
Rationale: St. John’s Wort is a potent inducer of hepatic cytochrome P450 enzymes, which
significantly increases the metabolism of warfarin and reduces its anticoagulant efficacy, putting
the patient at risk for clots. Maintaining consistent Vitamin K intake (A), practicing safety
precautions (C), and monitoring for bleeding (D) are appropriate patient safety actions.
CORRECT ANSWER : B
5. Which laboratory value must be monitored closely when initiating therapy with an aldosterone
antagonist?
A. Serum sodium
B. Serum glucose
C. Serum potassium
D. Serum calcium
Answer: C
Rationale: Aldosterone antagonists, such as spironolactone, promote sodium excretion but cause
the retention of potassium, creating a significant risk for life-threatening hyperkalemia. While
sodium monitoring is important, the potential for cardiac arrhythmias due to hyperkalemia
makes potassium the priority; glucose and calcium are not directly affected by the mechanism of
action.
CORRECT ANSWER : C
6. A patient is taking digoxin for atrial fibrillation. Which clinical manifestation is most indicative
of digoxin toxicity?
A. Increased appetite
B. Tinnitus
C. Visual disturbances such as yellow-green halos
, D. Hyperactive bowel sounds
Answer: C
Rationale: Visual disturbances, specifically xanthopsia (yellow-green halos) or blurred vision,
are classic signs of digoxin toxicity resulting from its effect on the retina. Increased appetite is
not a sign; tinnitus is associated with salicylate toxicity; and gastrointestinal symptoms usually
involve nausea and vomiting, not hyperactive bowel sounds.
CORRECT ANSWER : C
7. Which drug class is preferred for a patient with essential hypertension and a history of Type 2
Diabetes Mellitus with albuminuria?
A. Beta-blockers
B. Angiotensin-converting enzyme (ACE) inhibitors
C. Calcium channel blockers
D. Thiazide diuretics
Answer: B
Rationale: ACE inhibitors are the preferred class because they provide renoprotection by
reducing intraglomerular pressure and slowing the progression of diabetic nephropathy. While
other antihypertensives control blood pressure, they do not offer the same renal-protective
benefits for patients with albuminuria.
CORRECT ANSWER : B
8. When prescribing an HMG-CoA reductase inhibitor (statin), which instruction should be
emphasized to ensure patient safety?
A. Avoid grapefruit juice entirely
B. Report any unexplained muscle pain or weakness
C. Take the medication only if chest pain occurs
D. Increase intake of Vitamin K-rich foods
Answer: B
Rationale: Unexplained muscle pain or weakness may indicate rhabdomyolysis, a rare but
serious adverse effect of statin therapy that requires immediate discontinuation. While grapefruit
