Correct answer: II only

Drotrecogin alfa (Xigris) was an anticoagulant medication specifically formulated for intravenous administration. It was marketed as a lyophilized powder for injection, available in 5 mg and 20 mg vials, which aligns with option II. It was never available in oral suspension, tablet, or capsule forms, as its therapeutic action required direct intravenous delivery. (Note: Drotrecogin alfa was voluntarily withdrawn from the market in 2011.)

Question 33: Which metabolic pathway is PRIMARILY responsible for phase II conjugation of acetaminophen under normal dosing conditions?

Glucuronidation and sulfation (Correct answer)
Methylation
Glutathione conjugation
Oxidation via CYP2E1

Correct answer: Glucuronidation and sulfation

Under therapeutic doses, acetaminophen is primarily metabolized by glucuronidation (~55%) and sulfation (~30%); CYP2E1-mediated oxidation to NAPQI becomes significant only in overdose when conjugation pathways are saturated.

Question 34: In heart failure with reduced ejection fraction (HFrEF), which compensatory mechanism initially helps maintain cardiac output but ultimately worsens cardiac remodeling?

Decreased renin release
Activation of the renin-angiotensin-aldosterone system (RAAS) (Correct answer)
Decreased antidiuretic hormone secretion
Parasympathetic nervous system activation

Correct answer: Activation of the renin-angiotensin-aldosterone system (RAAS)

Sonata-Zaleplon
Sanctura-Trospium
Accolate-Zafirlukast
Levitra-Venlafaxine (Correct answer)

Correct answer: Levitra-Venlafaxine

Levitra is the brand name for the drug Vardenafil, which is used to treat erectile dysfunction. Venlafaxine, on the other hand, is an antidepressant sold under the brand name Effexor. Therefore, the pairing of Levitra with Venlafaxine is incorrect, while the other brand-generic matches provided are accurate.

Question 67: A patient with chronic kidney disease develops anemia. What is the primary pathophysiological reason?

Decreased erythropoietin production by the diseased kidneys (Correct answer)
Iron deficiency due to poor dietary intake
Vitamin B12 malabsorption secondary to renal tubular damage
Hemolysis caused by uremic toxins primarily

Correct answer: Decreased erythropoietin production by the diseased kidneys

The peritubular interstitial cells of the kidney are the primary source of erythropoietin; CKD destroys these cells, reducing EPO production and thereby red cell production.

Question 68: Which of the following equations accurately describes clearance for the majority of drugs?

Cl = QxE
All of the above (Correct answer)
Cl = Elimination rate/Cp
Cl = .7VD/t1/2

Correct answer: All of the above

All three equations provided are valid ways to describe or calculate drug clearance (Cl). Cl = QxE relates clearance to organ blood flow and extraction ratio. Cl = 0.7VD/t1/2 connects clearance to the volume of distribution and half-life. Cl = Elimination rate/Cp defines clearance as the rate of drug elimination divided by its plasma concentration, representing the volume of plasma cleared of drug per unit time.

Question 69: Which study design provides the strongest evidence for establishing causality between a drug exposure and an outcome?

Systematic review of case-control studies
Prospective cohort study
Randomized controlled trial (Correct answer)

Pharmacokinetic stereoselectivity only
Constitutional isomer activity differences
Pharmacodynamic stereoselectivity (Correct answer)
Tautomeric equilibrium effects

Correct answer: Pharmacodynamic stereoselectivity

When enantiomers differ in pharmacological potency at a receptor, this reflects pharmacodynamic stereoselectivity due to chiral receptor binding sites.

Question 74: Which antiviral agent inhibits the neuraminidase enzyme of influenza A and B viruses?

Ribavirin
Oseltamivir (Correct answer)
Ganciclovir
Acyclovir

Correct answer: Oseltamivir

Oseltamivir (Tamiflu) and zanamivir are neuraminidase inhibitors that prevent new viral particles from being released from infected cells.

Question 75: Digoxin-specific antibody fragments (Fab) work by:

Competitively blocking cardiac Na+/K+-ATPase
Inducing hepatic metabolism of digoxin
Increasing renal clearance of digoxin via active secretion
Binding free digoxin and removing it from receptor sites (Correct answer)

Correct answer: Binding free digoxin and removing it from receptor sites

Digoxin immune Fab fragments bind free digoxin molecules with high affinity, forming complexes that are renally excreted, removing digoxin from its toxic sites of action.

Question 76: Berkson's bias is a specific form of selection bias most commonly associated with which study design?

Hospital-based case-control studies (Correct answer)
Cohort studies
Cross-sectional studies
Randomized controlled trials

Correct answer: Hospital-based case-control studies

Berkson's bias occurs when both cases and controls are drawn from hospitalized patients, distorting the true association because hospitalization rates differ by exposure and disease.
