ATI Proctored Pharmacology Quizlet Questions
Question 1 of 5
Zanamivir is ordered for a patient with which disorder?
Correct Answer: C
Rationale: Zanamivir is an antiviral medication used to treat influenza, not herpes simplex virus or hepatitis B. Varicella-zoster virus is the cause of chickenpox and shingles, which are treated with other antivirals like acyclovir. This question seems to have an error, as zanamivir is not used for any of the listed conditions.
Question 2 of 5
The nurse is administering oxycodone to a patient. Which common side effect should the nurse teach the patient about?
Correct Answer: D
Rationale: Drowsiness is a common side effect of oxycodone, an opioid analgesic. Patients should be advised to avoid activities requiring alertness, such as driving, while taking this medication. Paresthesia (A), increased intracranial pressure (B), and occipital headache (C) are not typical side effects of oxycodone.
Question 3 of 5
A client with rheumatoid arthritis has been receiving hydroxychloroquine (Plaquenil) in recent months. The nurse tells the client to visit which of the following while on the treatment?
Correct Answer: B
Rationale: Hydroxychloroquine can cause retinal toxicity, leading to vision loss. Regular ophthalmologic examinations are essential to detect early signs of toxicity. While dental, pulmonary, and endocrine health are important, they are not directly related to hydroxychloroquine's side effects. Monitoring for retinal changes is critical to ensure the safe use of this medication.
Question 4 of 5
Which of the following is the antidote of first choice in the treatment of potentially fatal paracetamol overdose?
Correct Answer: B
Rationale: Paracetamol overdose risks fatal hepatotoxicity via NAPQI, a toxic metabolite depleting glutathione. Methionine replenishes glutathione orally, effective if given early, but less preferred due to slower action and GI upset. Acetylcysteine, administered IV or orally, directly supplies glutathione precursors, neutralizing NAPQI within the critical 8-12 hour window, making it the first-choice antidote per global guidelines (e.g., Rumack-Matthew nomogram). It's superior for its rapid efficacy, especially beyond 8 hours, preventing liver failure. Naloxone reverses opioids, irrelevant here. Dicobalt edetate treats cyanide poisoning, not paracetamol. Flumazenil targets benzodiazepines. Acetylcysteine's mechanism and timing flexibility ensure maximal survival, critical in emergency settings where overdose severity varies.
Question 5 of 5
A client is prescribed total parenteral nutrition (TPN). Which education should the nurse provide?
Correct Answer: C
Rationale: Total parenteral nutrition (TPN) for long-term use requires a central line because it delivers high-concentration nutrients directly into large veins, like the subclavian, to avoid peripheral vein damage and ensure effective nutrient distribution. Clients can manage TPN at home with proper training, debunking the idea they must stay hospitalized until it's discontinued. It's also administered continuously or cyclically via an infusion pump for precise control, not on a twice-weekly outpatient schedule, which aligns with parenteral nutrition's complexity. The pump ensures steady delivery, critical for metabolic stability, while TPN's comprehensive nutritional support meets all dietary needs intravenously. This central line approach is standard for prolonged therapy, distinguishing it from short-term peripheral options, and supports home management, enhancing quality of life while addressing nutritional deficits effectively.
