ATI RN Pharmacology 2023 Questions
Question 1 of 5
The following drugs may be administered transcutaneously to produce their systemic therapeutic effect:
Correct Answer: A
Rationale: GTN patches deliver the drug transdermally, bypassing first-pass metabolism and providing systemic therapeutic action.
Question 2 of 5
A client takes calcium three times a day in the form of supplements. The nurse will advise the client to take the drug
Correct Answer: D
Rationale: Calcium absorbs best with food-fat aids uptake, per pharmacokinetics-unlike empty stomach or tea (tannins bind). Zinc competes-separate dosing. Food optimizes, per guidance.
Question 3 of 5
A client is prescribed an intranasal corticosteroid. What should the nurse include in client education about this drug?
Correct Answer: D
Rationale: Intranasal corticosteroids cause burning and nosebleeds . They're preventive (choice B wrong), dosing is fixed (choice C wrong). D educates on side effects, making it key.
Question 4 of 5
Haloperidol:
Correct Answer: B
Rationale: Haloperidol, a typical antipsychotic, causes hypotension less than phenothiazines, so that's not its hallmark. It's highly prone to extrapyramidal side effects (EPS) like dystonia due to strong D2 receptor blockade, a true statement. Arrhythmias (e.g., QT prolongation) occur but aren't its primary issue. Antimuscarinic effects are minimal compared to other antipsychotics. Confusion is possible but not its defining toxicity. EPS prominence drives the need for adjunctive anticholinergics in treatment, a key consideration in schizophrenia management.
Question 5 of 5
A patient looks up the drug he is taking in a drug guide. The patient asks the nurse why the physician prescribed a medication that has a lethal dose measure. What is the best response by the nurse?
Correct Answer: B
Rationale: Lethal dose (e.g., LD50) from research guides safe dosing by showing toxicity thresholds, reassuring the patient it informs, not dictates, prescription. It's not just research trivia-doctors use it indirectly. Side effect watching doesn't explain it. Deferring to the doctor avoids education. Research value ties to safety, clarifying its relevance.
