Question 1

Which of the following best describes the primary antibacterial mechanism of action of beta-lactam antibiotics such as amoxicillin and penicillin G?

Inhibition of bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and blocking peptidoglycan cross-linking Inhibition of the 30S ribosomal subunit preventing bacterial protein translation Inhibition of bacterial DNA gyrase and topoisomerase IV preventing DNA replication Disruption of bacterial cell membrane permeability causing leakage of intracellular ions

Correct Answer:

Inhibition of bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and blocking peptidoglycan cross-linking

Question 2

A 52-year-old hypertensive patient who was started on enalapril 10 mg daily 3 weeks ago presents to the clinic complaining of a persistent, non-productive dry cough. What is the physiological mechanism responsible for this adverse drug reaction?

Direct allergic hypersensitivity causing laryngeal bronchospasm Accumulation of bradykinin and substance P in the respiratory tract due to ACE inhibition Excessive accumulation of angiotensin II causing pulmonary capillary vasoconstriction Inhibition of surfactant production by alveolar type II pneumocytes

Correct Answer:

Accumulation of bradykinin and substance P in the respiratory tract due to ACE inhibition

Question 3

A 58-year-old patient with type 2 diabetes mellitus is prescribed metformin. Which of the following statements correctly describes its primary mechanism of action and major clinical safety precaution?

Stimulates insulin release from pancreatic beta cells; carries a high risk of profound hypoglycemia Decreases hepatic gluconeogenesis and increases peripheral insulin sensitivity; contraindicated in severe renal impairment due to risk of lactic acidosis Inhibits intestinal alpha-glucosidase enzymes; requires dose reduction in chronic liver cirrhosis Inhibits sodium-glucose cotransporter-2 (SGLT2) in proximal renal tubules; carries a risk of urinary tract infections

Correct Answer:

Decreases hepatic gluconeogenesis and increases peripheral insulin sensitivity; contraindicated in severe renal impairment due to risk of lactic acidosis

Question 4

In paracetamol (acetaminophen) toxicity, hepatic necrosis occurs due to the accumulation of a toxic reactive metabolite. Which metabolite is responsible, and which specific antidote is administered to replenish hepatic glutathione stores?

N-acetyl-p-benzoquinone imine (NAPQI); treated with N-acetylcysteine (NAC) Para-aminophenol; treated with flumazenil Glucuronide conjugate; treated with deferoxamine Acetaldehyde; treated with fomepizole

Correct Answer:

N-acetyl-p-benzoquinone imine (NAPQI); treated with N-acetylcysteine (NAC)

Question 5

Co-trimoxazole is a fixed-dose combination of sulfamethoxazole and trimethoprim. Why is this combination therapeutically synergistic and bactericidal rather than bacteriostatic?

Sulfamethoxazole inhibits bacterial cell wall cross-linking while trimethoprim disrupts the cytoplasmic membrane Sulfamethoxazole competitively inhibits dihydropteroate synthase and trimethoprim inhibits dihydrofolate reductase in sequential steps of bacterial folate synthesis Sulfamethoxazole increases bacterial cell permeability allowing higher intracellular accumulation of trimethoprim Trimethoprim inhibits hepatic CYP450 enzymes preventing the metabolic degradation of sulfamethoxazole

Correct Answer:

Sulfamethoxazole competitively inhibits dihydropteroate synthase and trimethoprim inhibits dihydrofolate reductase in sequential steps of bacterial folate synthesis
