ATI RN Pharmacology 2023 Questions
Question 1 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.
Question 2 of 5
The newly licensed nurse is preparing to administer a high dose of androgen to the female client. The nurse manager asks for the rationale. What is the best response by the new nurse?
Correct Answer: B
Rationale: High-dose androgens in females are used palliatively for certain breast cancers, especially hormone-sensitive ones, to suppress estrogen-driven tumor growth, easing symptoms in advanced disease. Athletic performance enhancement via androgens, while feasible, isn't clinically indicated and is illegal in regulated contexts. Brain cancer lacks evidence for androgen treatment, as it doesn't target neurological tumors. Sexual reassignment uses testosterone for masculinization, but high doses in clinical settings typically tie to cancer care, not transition. Breast cancer aligns with a recognized therapeutic use, leveraging androgens' anti-estrogenic effects, making it the most valid clinical rationale here.
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
A 17-year-old man presents to the emergency department with a persistent cough and nasal congestion. He has been taking various prescription cough and cold medicines but did not know their names. A urine drug screen is positive for amphetamines. When confronted with this information, he vehemently denies amphetamine use. What is the best explanation?
Correct Answer: B
Rationale: Positive amphetamine screen with cough/cold medicine use suggests a false positive from ephedrine . Ephedrine, in decongestants, cross-reacts with amphetamine assays. Codeine and marijuana don't. Lying or sample mix-up (E) are less likely given his denial and context. This common false positive explains the discrepancy.
Question 5 of 5
What serious adverse reaction can occur with the loop diuretic Furosemide?
Correct Answer: A
Rationale: Stevens-Johnson syndrome is a severe and potentially life-threatening adverse reaction associated with the use of Furosemide, a loop diuretic. It is characterized by a severe skin reaction that can cause rashes, blisters, and mucous membrane involvement. Stevens-Johnson syndrome is considered a medical emergency and requires immediate discontinuation of the offending medication. Monitoring and management should be promptly initiated to prevent serious complications. Other side effects of Furosemide include electrolyte imbalances, ototoxicity, and dehydration, but Stevens-Johnson syndrome is a particularly serious adverse reaction that requires immediate attention.
