Question 1 of 5
A nurse is collecting data from a client who has been taking carbamazepine. Which of the following is an adverse effect of carbamazepine and should be reported to the provider?
Correct Answer: A
Rationale: Sore throat may signal agranulocytosis, a serious carbamazepine side effect. Others aren't typical.
Question 2 of 5
A nurse is reviewing a list of current medications for a client who is starting therapy with furosemide. Which of the following medications should the nurse identify as being contraindicated?
Correct Answer: A
Rationale: Furosemide reduces lithium clearance, risking toxicity. It has no significant contraindications with albuterol, levothyroxine, or cetirizine.
Question 3 of 5
A nurse is caring for a client who has chronic hypertension. The client's morning vital signs include BP 140/80 mm Hg, heart rate 54/min, and respiratory rate 18/min. Which of the following medications should the nurse plan to withhold?
Correct Answer: D
Rationale: Atenolol, a beta-blocker, may worsen bradycardia (HR 54/min). BP is controlled, so others can continue.
Question 4 of 5
A nurse is reinforcing teaching with a newly licensed nurse about age-related changes that affect medication administration for older adult clients. Which of the following information should the nurse include?
Correct Answer: A
Rationale: Aging reduces renal function, slowing drug excretion and increasing toxicity risk. Brain receptor sensitivity varies, gastric emptying slows, and hepatic metabolism decreases.
Question 5 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.
