Correct Answer is C

Explanation

Choice A rationale

Acetaminophen is not used for preventing osteoporosis.

A. This medication is bactericidal due to inhibition of an enzyme necessary for DNA replication. B. This medication accelerates bacterial growth. C. This medication is a diuretic that works on the distal tubule of the nephron. D. This medication is a beta-blocker that blocks beta-2 receptors, which results in a lower heart rate and blood pressure.

Correct Answer is A

Explanation

Choice A rationale

Ciprofloxacin is a bactericidal antibiotic that works by inhibiting DNA gyrase, an enzyme necessary for DNA replication in bacteria. This prevents bacterial cells from replicating and ultimately leads to their death.

Choice B rationale

Ciprofloxacin does not accelerate bacterial growth; instead, it inhibits growth by preventing DNA replication.

Choice C rationale

Ciprofloxacin is not a diuretic. Diuretics work on the kidneys to increase urine production, but ciprofloxacin targets bacterial DNA replication.

Choice D rationale

Ciprofloxacin is not a beta-blocker and does not lower heart rate or blood pressure. Beta-blockers work by blocking beta-adrenergic receptors in the heart.
