Question 1 of 5
A nurse is collecting data from a client who states she recently started taking garlic as an herbal supplement. The nurse should advise the client to stop taking garlic due to a potential reaction with which of the following client medications?
Correct Answer: A
Rationale: Garlic increases bleeding risk with warfarin due to antiplatelet effects. No significant interactions exist with the others.
Question 2 of 5
A nurse is reinforcing teaching about phenytoin with a client who had a tonic-clonic seizure. Which of the following information should the nurse include in the teaching?
Correct Answer: B
Rationale: Phenytoin commonly causes gingival hyperplasia, requiring oral hygiene monitoring. It does not lower potassium, ginkgo biloba has no significant interaction, and photosensitivity is less critical than hyperplasia.
Question 3 of 5
A nurse is planning to administer a tuberculin skin test to a client who has had an exposure to tuberculosis. Which of the following actions should the nurse plan to take?
Correct Answer: A
Rationale: A scar-free site ensures accurate TST results. Massaging distorts results, the angle should be 5-15°, and the dose is 0.1 mL, not 0.3-0.5 mL.
Question 4 of 5
A nurse is administering the first dose of ramipril to a client who has hypertension. The client reports feeling dizzy and lightheaded. Which of the following should the nurse administer?
Correct Answer: D
Rationale: Dizziness from ramipril suggests hypotension; an IV fluid bolus raises blood pressure. Carbohydrates treat hypoglycemia, diphenhydramine allergies, and naloxone opioid overdose—none apply here.

A nurse is preparing to administer erythromycin PO to a client who has an infection. The nurse checks the client's medical record and notes that the client has a severe allergy to penicillin. Which of the following actions should the nurse take?
Correct Answer: B
