Nokea
An 80-year-old patient with a history of renal insufficiency was recently started on cimetidine. Which assessment finding indicates that the patient may be experiencing an adverse effect of the medication?
Correct Answer: B
Rationale: The correct answer is B: New onset disorientation to time and place. Cimetidine can cause adverse effects on the CNS system, especially in elderly patients with renal or hepatic impairment. This may manifest as confusion, hallucinations, lethargy, restlessness, or seizures. Pain with urination (choice A) is not typically associated with cimetidine use, and HR changes (choice C) are more likely related to other factors. Choice D is not a valid option.
