ATI Practice Exam Pharmacology The Endocrine System Questions
Question 1 of 4
Which of the following drugs is most useful for the treatment of absence seizures?
Correct Answer: D
Rationale: Lamotrigine, a broad-spectrum antiepileptic, treats absence seizures by stabilizing sodium channels and inhibiting glutamate release, though less specific than ethosuximide. Topiramate and levetiracetam manage multiple seizure types but aren't first-line for absence. Tiagabine, a GABA reuptake inhibitor, may worsen absence seizures. Zonisamide has broad efficacy but less absence focus. While ethosuximide is gold standard, lamotrigine's utility in absence, especially in mixed epilepsies, and clinical evidence make it the most useful here among options.
Question 2 of 4
The client takes diphenhydramine (Benadryl) but forgets to tell the physician about this drug when a monoamine oxidase inhibitor (MAOI) drug is prescribed for depression. What will the best assessment by the nurse reveal?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 4
A client with bipolar disorder is prescribed lithium carbonate. Which symptom should the nurse teach the client to report?
Correct Answer: C
Rationale: Lithium stabilizes mood but risks toxicity (e.g., >1.5 mEq/L), causing tremors , a neurologic sign needing reporting to adjust dosing or check levels. Thirst and weight gain are common, manageable. Nausea occurs but is less urgent unless severe. Tremors indicate potential overdose, critical in bipolar disorder where narrow therapeutic range demands vigilance, making C the key symptom to report.
