Which of the following is NOT a phase of pharmacokinetics?
Excretion.
Phlebitis.
Distribution.
Absorption.
The Correct Answer is B
Choice A rationale
Excretion is a phase of pharmacokinetics where the drug or its metabolites are eliminated from the body, primarily via the kidneys.
Choice B rationale
Phlebitis is inflammation of a vein and is not a phase of pharmacokinetics. It is a medical condition rather than a pharmacokinetic process.
Choice C rationale
Distribution is a phase of pharmacokinetics where the drug is dispersed throughout the body’s tissues and fluids after absorption.
Choice D rationale
Absorption is a phase of pharmacokinetics where the drug is absorbed into the bloodstream from the site of administration.

Correct Answer is A
Explanation

Acetaminophen is a pain reliever and fever reducer, which does not treat digoxin toxicity.

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.
