Correct Answer is C

Explanation

Sublingual and buccal medications are rapidly absorbed because they are placed under the tongue or between the cheek and gum, where they dissolve and are absorbed directly into the bloodstream through the mucous membranes in the mouth. This allows for rapid absorption and bypasses the liver’s first-pass metabolism.

A. Fever B. Pruritus C. Amber urine D. Diarrhea

Correct Answer is B

Explanation

An allergic reaction can occur in response to medication, and oxacillin is known to have the potential for causing allergic reactions. Symptoms of an allergic reaction may include rash, hives, itching, swelling, difficulty breathing, and anaphylaxis. Fever, amber urine, and diarrhoea are not typically associated with an allergic reaction to oxacillin.

Therefore, the nurse should monitor the client for any signs of an allergic reaction, particularly pruritus or itching, and report them to the healthcare provider promptly.
