An HIV-positive client who has been started on highly active antiretroviral therapy (HAART) came back for a follow-up checkup. Which of the following will be the most helpful in determining the response to the therapy?

Correct Answer: C

Rationale: The most helpful test in determining the response to highly active antiretroviral therapy (HAART) in an HIV-positive client is a viral load test. A viral load test measures the amount of HIV in the blood by counting the number of copies of the virus present. Monitoring viral load levels over time provides vital information about how well the antiretroviral medications are working in suppressing the replication of the virus. A decrease in viral load indicates a positive response to the therapy, while an increase may suggest treatment failure or the development of drug resistance. Regular monitoring of viral load is a crucial aspect of managing HIV infection and assessing the effectiveness of antiretroviral therapy.

Correct Answer: A

Rationale: Ondansetron, which is commonly used to prevent nausea and vomiting, can be administered via three routes: Orally (PO), Intravenously (IV), and Rectally (Rectal). These routes allow for flexible administration based on the patient's condition and needs. Intramuscular (IM) administration is not a recognized route for ondansetron administration.

Correct Answer: B

Rationale: Cocaine is unique among local anesthetics because it undergoes metabolism by plasma esterases, unlike other local anesthetics which are typically metabolized by the liver. This rapid metabolism by plasma esterases contributes to its short duration of action as a local anesthetic. This property of cocaine also contributes to its potential for systemic toxicity and drug interactions, making it important to consider when using cocaine in a clinical setting.

Correct Answer: B

Rationale: Erythromycin is a suitable alternative for patients allergic to penicillin. Erythromycin belongs to the macrolide class of antibiotics and is effective against a wide range of bacterial infections. It is generally well-tolerated and can be used as an alternative in cases of penicillin allergy.cephalosporins, tetracyclines, sulfonamides, and aminoglycosides like gentamicin should not be prescribed to a patient with a known penicillin allergy as they can potentially cross-react and cause allergic reactions.
