Pharmacology Assessment 2 ATI Capstone Questions
Question 1 of 5
Which of the following antipsychotic agents is considered to be the most potent and, thus, have the highest risk of extrapyramidal symptoms?
Correct Answer: B
Rationale: Fluphenazine, a high-potency first-generation antipsychotic, strongly blocks D2 receptors, requiring lower doses for efficacy but increasing EPS risk (e.g., dystonia, parkinsonism) due to intense dopamine antagonism in the nigrostriatal pathway. Thioridazine and chlorpromazine, low-potency first-generation drugs, have weaker D2 affinity, causing more sedation and anticholinergic effects than EPS. Quetiapine, a second-generation antipsychotic, has low D2 potency and minimal EPS. Clozapine avoids EPS with broad receptor activity. Fluphenazine's potency, measured by dose equivalence and clinical data, correlates with its elevated EPS risk, distinguishing it here.
Question 2 of 5
The client tells the nurse that her symptoms have become worse since she has been using oxymetazoline (Afrin) for nasal congestion. What is the best assessment question for the nurse to ask?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A client with chronic obstructive pulmonary disease (COPD) is prescribed theophylline. Which laboratory value should the nurse monitor?
Correct Answer: A
Rationale: Theophylline, a bronchodilator, treats COPD but has a narrow therapeutic range (10-20 mcg/mL). Monitoring theophylline levels prevents toxicity (e.g., seizures, tachycardia) or subtherapeutic dosing, ensuring efficacy. Sodium , glucose , and platelets aren't directly impacted. Blood level checks align with theophylline's pharmacokinetics'hepatic metabolism, variable clearance'critical in COPD where respiratory support hinges on precision. This focus prevents adverse outcomes, making A the key value to monitor for safe, effective therapy.
