8. Toxicology, Adverse Drug Reactions, and Drug Interactions
1. A 62-year-old male with chronic heart failure and reduced ejection fraction is initiated on
sacubitril/valsartan. Before switching from an ACE inhibitor to this combination drug, what
mandatory washout period must be observed to prevent a life-threatening adverse reaction?
A. 12 hours
B. 36 hours
C. 7 days
D. 14 days
CORRECT ANSWER : B
, Rationale: Sacubitril/valsartan combines an angiotensin receptor blocker (ARB) with a
neprilysin inhibitor. Neprilysin also degrades bradykinin; concurrent use with an ACE inhibitor
significantly increases the risk of angioedema. Therefore, a mandatory 36-hour washout period
is required when transitioning from an ACE inhibitor to sacubitril/valsartan.
2. A 55-year-old male with type 2 diabetes mellitus and stage 3 chronic kidney disease is
prescribed empagliflozin. Which physiological mechanism accounts for the renal protective
effects of Sodium-Glucose Co-transporter 2 (SGLT2) inhibitors?
A. Direct stimulation of proximal tubular cellular proliferation
B. Reduction of intraglomerular pressure via restoration of tubuloglomerular feedback
C. Enhancement of systemic vasodilation through peripheral beta-2 agonism
D. Blockade of mineralocorticoid receptors in the distal convoluted tubule
CORRECT ANSWER : B
Rationale: SGLT2 inhibitors block sodium and glucose reabsorption in the proximal tubule,
delivering more sodium to the macula densa. This restores tubuloglomerular feedback, leading
to afferent arteriolar vasoconstriction, a drop in intraglomerular pressure, and subsequent
slowing of chronic kidney disease progression.
3. A 48-year-old female presents with hyperthyroidism and is prescribed propylthiouracil (PTU)
during her first trimester of pregnancy. What is the primary pharmacological rationale for
selecting PTU over methimazole during early gestation?
A. PTU has a longer half-life, allowing for once-daily dosing regimens
B. Methimazole is associated with rare teratogenic embryopathy such as aplasia cutis
C. PTU completely blocks thyroid hormone release from the colloid gland
D. Methimazole selectively targets peripheral beta receptors to lower heart rate
CORRECT ANSWER : B
Rationale: Methimazole has been linked to specific congenital malformations in the first
trimester, including choanal atresia and aplasia cutis. Propylthiouracil is preferred during the
first trimester because it lacks these specific teratogenic associations, though it carries a higher
risk of severe hepatotoxicity.
4. A nurse practitioner is managing an older adult patient who is prescribed lithium carbonate for
bipolar disorder. Which concurrent medication prescription requires immediate intervention due
to the risk of severe lithium toxicity?
, A. Acetaminophen for mild osteoarthritis pain
B. Hydrochlorothiazide for hypertension
C. Amlodipine for coronary artery disease
D. Levothyroxine for hypothyroidism
CORRECT ANSWER : B
Rationale: Thiazide diuretics like hydrochlorothiazide promote renal sodium excretion, leading
to compensatory proximal tubular reabsorption of sodium and, consequently, increased
reabsorption of lithium. This drug-drug interaction significantly decreases lithium clearance,
precipitating life-threatening toxicity.
5. A 70-year-old male with severe chronic obstructive pulmonary disease (COPD) is prescribed a
long-acting muscarinic antagonist (LAMA). What is the primary pharmacodynamic action of
LAMAs in the airway?
A. Stimulation of beta-2 adrenergic receptors to relax bronchial smooth muscle
B. Competitive blockade of M3 muscarinic receptors preventing bronchoconstriction
C. Inhibition of phosphodiesterase-4 to reduce inflammatory cell infiltration
D. Stabilization of mast cell membranes to block histamine release
CORRECT ANSWER : B
Rationale: Long-acting muscarinic antagonists, such as tiotropium, competitively and reversibly
block M3 muscarinic receptors on airway smooth muscle. This blocks acetylcholine-induced
bronchoconstriction and reduces mucous gland secretion, providing sustained bronchodilation.
6. A patient is prescribed warfarin for stroke prophylaxis secondary to atrial fibrillation. Laboratory
monitoring reveals an International Normalized Ratio (INR) of 5.8 with no active bleeding.
According to clinical guidelines, what is the most appropriate management strategy?
A. Immediately administer high-dose intravenous vitamin K and fresh frozen plasma
B. Hold the next few doses of warfarin, monitor INR, and resume at a lower dose when
therapeutic
C. Double the daily dose of warfarin to accelerate clearance and stabilize clotting factors
D. Switch immediately to full-dose unfractionated heparin without checking baseline labs
, CORRECT ANSWER : B
Rationale: For patients taking warfarin with an INR between 4.5 and 10.0 and no evidence of
bleeding, the guideline recommendation is to withhold one or two doses of warfarin, monitor the
INR closely, and resume therapy at an adjusted, lower dose once the INR returns to the
therapeutic range.
7. A 30-year-old female with major depressive disorder and a history of bulimia nervosa is
evaluated for pharmacotherapy. Which antidepressant medication is strictly contraindicated due
to safety concerns?
A. Sertraline
B. Bupropion
C. Escitalopram
D. Duloxetine
CORRECT ANSWER : B
Rationale: Bupropion lowers the seizure threshold significantly. Because patients with eating
disorders such as bulimia or anorexia nervosa have an elevated baseline risk of electrolyte
imbalances and seizures, bupropion is strictly contraindicated in this population.
8. A patient with hyperlipidemia is initiated on rosuvastatin. Two months later, she reports severe
generalized myalgias and dark-colored urine. Which laboratory assessment should be prioritized
immediately?
A. Serum amylase and lipase levels
B. Serum creatine kinase (CK) and a comprehensive renal function panel
C. Fasting blood glucose and glycated hemoglobin
D. Thyroid-stimulating hormone and free T4 assays
CORRECT ANSWER : B
Rationale: Severe muscle pain accompanied by dark urine in a patient taking a statin suggests
statin-induced rhabdomyolysis. Measuring serum creatine kinase (CK) levels and assessing
renal function (BUN and creatinine) are vital to detect acute kidney injury resulting from
myoglobinuria.
