ATI Pharmacology Assessment 2 Questions
Question 1 of 5
The nurse is giving instructions to a client receiving phenytoin (Dilantin). The nurse concludes that the client has a sufficient knowledge if the client states that:
Correct Answer: D
Rationale: Monitoring serum phenytoin levels is essential to ensure therapeutic efficacy and avoid toxicity. Wearing a medical alert tag is recommended for clients on phenytoin. Alcohol should be avoided, and taking the medication with milk can interfere with absorption. Therefore, the correct statement indicating sufficient knowledge is about monitoring serum levels.
Question 2 of 5
Toxicity of nicotine containing products:
Correct Answer: D
Rationale: Nicotine toxicity can cause neuromuscular blockade (late phase), but atropine treats muscarinic effects, not paralysis, so that's false. It causes hypertension initially via catecholamine release, not hypotension, making that false. It harms the fetus (e.g., growth restriction), so that's incorrect. Benzodiazepines control agitation and seizures symptomatically, a true statement, useful in acute poisoning. Nausea/vomiting resolve faster than days. Benzodiazepines' symptomatic relief is a practical approach, addressing CNS overstimulation in nicotine overdose.
Question 3 of 5
The client says to the nurse, 'My wife and I take the same drug, but we have different side effects. Are we doing something wrong?' What is the best response by the nurse?
Correct Answer: A
Rationale: Sex differences affect drug metabolism (e.g., liver enzymes, body fat), leading to varied side effects, a normal pharmacodynamic variation, reassuring the client they're not at fault. Checking the drug delays a clear answer. Generic vs. brand typically doesn't alter side effects-bioequivalence is required. Uncertainty muddies education. Sex-based differences offer a concise, accurate explanation, normalizing their experience and enhancing understanding.
Question 4 of 5
A drug has been prescribed to decrease the effects of an endogenous chemical. The nurse would place this drug in which category?
Correct Answer: C
Rationale: Antagonists block endogenous chemicals' effects (e.g., beta-blockers vs. adrenaline), reducing activity. Agonists mimic, partial agonists partially activate, and agonist-antagonists mix effects. Decreasing an endogenous effect fits antagonists, a pharmacodynamic classification.
Question 5 of 5
The patient has been depressed, and the physician plans to begin treatment with an antidepressant medication. In performing the initial assessment, what is the most important question for the nurse to ask?
Correct Answer: D
Rationale: Suicide risk is critical in depression-antidepressants may increase it early (e.g., energy before mood lifts), per black box warnings. Alcohol use, allergies, and duration matter but aren't immediate life threats. Suicidal thoughts guide urgent intervention, per psychiatric priority.
