Rationale: The healthcare professional should withhold the medication and notify the provider of the client's previous reaction to penicillin. This information is crucial for the provider to prescribe an alternative antibiotic. Allergic reactions to penicillin can range from mild to severe anaphylaxis, so prior sensitization should be reported to the provider to avoid potential adverse reactions.

Rationale: Regular insulin, also known as short-acting insulin, typically exhibits a peak effect around 1 to 5 hours following administration. This rapid onset and peak effect make it suitable for managing postprandial glucose levels. In contrast, Insulin glargine is a long-acting insulin with no pronounced peak effect, NPH insulin has an intermediate duration of action, and Insulin lispro is a rapid-acting insulin that peaks within 30 minutes to 2.5 hours after administration.

Correct Answer: D

Rationale: An adverse effect of prochlorperazine is acute dystonia, which is evidenced by spasms of the muscles in the face, neck, and tongue. Diphenhydramine is used to suppress extrapyramidal effects of prochlorperazine, making it the most appropriate choice to address the client's spasms.

Correct Answer: C

Rationale: Sucralfate can interfere with the absorption of phenytoin. To prevent this interaction, the client should allow a 2-hour interval between taking sucralfate and phenytoin. This timing helps to ensure adequate absorption and effectiveness of both medications without compromising therapeutic outcomes.
