A nurse is preparing an in-service about all the phases of pharmacokinetics.
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.

Explanation
Choice A rationale
Metformin is an oral hypoglycemic agent used to manage type 2 diabetes mellitus, not hypertension.
Choice B rationale
Lisinopril is an ACE inhibitor that relaxes blood vessels, reducing blood pressure.
Choice C rationale
Metoprolol is a beta-blocker that decreases heart rate and cardiac output, lowering blood pressure.
Choice D rationale
Metronidazole is an antibiotic used to treat bacterial infections, not hypertension.
Correct Answer is A
Explanation
Choice A rationale
Rotating injection sites helps prevent lipohypertrophy, which is the thickening of subcutaneous tissue due to repeated insulin injections at the same site.
Choice B rationale
Performing injections at the same location every time increases the risk of lipohypertrophy, leading to poor insulin absorption and erratic glucose control.
Choice C rationale
Administering an additional dose of insulin as needed does not address the issue of lipohypertrophy and can lead to hypoglycemia if not carefully monitored.
Choice D rationale
Insulin is a peptide hormone that must be injected. Taking it orally is ineffective as it would be broken down in the digestive system.
