,Q1. A patient with a history of chronic kidney disease (eGFR 25 mL/min/1.73m²) requires treatment for a
urinary tract infection caused by a multidrug-resistant organism. Which of the following antibiotics requires
the most significant dose adjustment and careful monitoring due to its pharmacokinetic profile in renal
impairment?
A. Nitrofurantoin
B. Ciprofloxacin
C. Amoxicillin-clavulanate
D. Trimethoprim-sulfamethoxazole
Correct Answer: D. Trimethoprim-sulfamethoxazole
Rationale: Trimethoprim-sulfamethoxazole (TMP-SMX) is primarily renally excreted and accumulates in renal
impairment, increasing risk of hyperkalemia (due to trimethoprim's amiloride-like effect) and crystalluria.
Nitrofurantoin is contraindicated in eGFR <30 mL/min due to lack of efficacy and increased toxicity. Ciprofloxacin
requires dose adjustment but is less nephrotoxic. Amoxicillin-clavulanate is relatively safe but may need
adjustment; TMP-SMX poses the greatest risk.
Why Wrong:
A - Nitrofurantoin is contraindicated in eGFR <30, but the primary concern is lack of efficacy and peripheral
neuropathy, not dose adjustment per se.
B - Ciprofloxacin requires dose adjustment but does not carry the same risk of hyperkalemia and crystalluria
as TMP-SMX.
C - Amoxicillin-clavulanate is generally safe with minor adjustment; it does not have the same level of renal
toxicity as TMP-SMX.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 46, 48.
Q2. A patient on warfarin for atrial fibrillation develops acute deep vein thrombosis. The decision is made to
bridge with a parenteral anticoagulant. Which of the following agents, when used concomitantly with
warfarin, requires monitoring of anti-Xa levels to ensure therapeutic effect and minimize bleeding risk?
A. Unfractionated heparin (UFH)
B. Enoxaparin
C. Fondaparinux
D. Bivalirudin
Correct Answer: B. Enoxaparin
Rationale: Enoxaparin (a low-molecular-weight heparin) requires anti-Xa monitoring in certain populations (e.g.,
renal impairment, obesity, pregnancy) to ensure adequate dosing and avoid accumulation. UFH is monitored via
aPTT, not anti-Xa. Fondaparinux is monitored via anti-Xa but is rarely used for bridging. Bivalirudin is monitored
via aPTT or ACT.
Why Wrong:
A - Unfractionated heparin is monitored using aPTT, not anti-Xa.
C - Fondaparinux can be monitored with anti-Xa, but it is not the standard for bridging; enoxaparin is more
common.
D - Bivalirudin is monitored via aPTT or ACT, not anti-Xa.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 35, 36.
Q3. A patient with type 2 diabetes mellitus and established atherosclerotic cardiovascular disease (ASCVD) is
currently on metformin and insulin glargine. Despite optimal insulin titration, HbA1c remains 9.2%.
According to the latest ADA guidelines, which of the following agents should be added to reduce
cardiovascular mortality?
A. Liraglutide
B. Sitagliptin
C. Glipizide
Page 3
, D. Pioglitazone
Correct Answer: A. Liraglutide
Rationale: Liraglutide, a GLP-1 receptor agonist, has demonstrated cardiovascular benefit in patients with type 2 diabetes and
ASCVD (LEADER trial), reducing major adverse cardiovascular events. Sitagliptin (DPP-4 inhibitor) is neutral for CV
outcomes. Glipizide (sulfonylurea) has no CV benefit and may increase risk. Pioglitazone (TZD) is associated with heart
failure risk and lacks CV mortality reduction.
Why Wrong:
B - Sitagliptin has a neutral effect on cardiovascular outcomes, not reduction in mortality.
C - Glipizide does not reduce cardiovascular mortality and may increase risk of hypoglycemia.
D - Pioglitazone is associated with increased risk of heart failure and does not reduce cardiovascular mortality.
Reference: American Diabetes Association. (2026). Standards of Medical Care in Diabetes. Diabetes Care, 49(Suppl 1).
Q4. A patient with major depressive disorder has failed to respond to adequate trials of two different SSRIs
and one SNRI. The decision is made to initiate a monoamine oxidase inhibitor (MAOI). Which of the
following dietary restrictions is most critical to prevent a hypertensive crisis?
A. Avoidance of all dairy products
B. Avoidance of foods containing tyramine
C. Restriction of sodium intake to <2 g/day
D. Avoidance of caffeine-containing beverages
Correct Answer: B. Avoidance of foods containing tyramine
Rationale: MAOIs inhibit the breakdown of tyramine, a vasoactive amine found in aged cheeses, cured meats,
fermented foods, and certain alcoholic beverages. Accumulation of tyramine can lead to severe hypertension and
potential stroke. Dairy products are generally safe unless aged. Sodium restriction is not directly related. Caffeine
may cause mild blood pressure elevation but not hypertensive crisis.
Why Wrong:
A - Most dairy products are low in tyramine; only aged cheeses are problematic.
C - Sodium restriction is not required; tyramine avoidance is critical.
D - Caffeine can increase blood pressure but does not cause hypertensive crisis with MAOIs.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 30.
Q5. A patient with severe, refractory hypertension is started on a combination of hydralazine and isosorbide
dinitrate. Which of the following best describes the synergistic mechanism of this combination in reducing
afterload and improving outcomes in heart failure with reduced ejection fraction?
A. Hydralazine increases cGMP and isosorbide dinitrate increases cAMP, leading to vasodilation
B. Hydralazine is a direct arteriolar vasodilator and isosorbide dinitrate is a venodilator, together reducing
preload and afterload
C. Hydralazine inhibits ACE and isosorbide dinitrate blocks beta-receptors, reducing cardiac workload
D. Hydralazine stimulates nitric oxide production and isosorbide dinitrate inhibits phosphodiesterase-5
Correct Answer: B. Hydralazine is a direct arteriolar vasodilator and isosorbide dinitrate is a venodilator,
together reducing preload and afterload
Rationale: Hydralazine directly relaxes arteriolar smooth muscle, reducing systemic vascular resistance
(afterload). Isosorbide dinitrate dilates venous capacitance vessels, reducing preload. The combination decreases
myocardial oxygen demand and improves cardiac output. This synergy is particularly beneficial in African
American patients with HFrEF. Option A is incorrect because hydralazine does not increase cGMP; nitrates do.
Option C is false; neither drug affects ACE or beta-receptors. Option D is incorrect; hydralazine does not stimulate
NO production significantly.
Why Wrong:
A - Hydralazine does not increase cGMP; nitrates increase cGMP via NO, not cAMP.
C - Hydralazine is not an ACE inhibitor; isosorbide dinitrate is not a beta-blocker.
