Question 1 of 5
The client is receiving a very expensive medication. The client asks the nurse why the medicine is so expensive. What is the best response by the nurse?
Correct Answer: C
Rationale: High drug costs stem from research, development, and production expenses-years of trials and manufacturing-requiring companies to recover investments, a factual explanation. Insurance coverage sidesteps the question. Advertising adds cost but isn't primary. Accountability is opinion, not answer. Development costs provide a clear, neutral reason, educating the client on pharmaceutical economics.

Question 3 of 5
A mother brings her 4-year-old son to the emergency department after discovering him eating her iron supplement. Which of the following should be administered to chelate the excess iron in his body?
Correct Answer: B
Rationale: Iron overdose in a child requires a specific chelator. Deferoxamine binds ferric iron, forming ferrioxamine, excreted renally. EDTA chelates calcium and lead, not iron-specific. Dimercaprol treats heavy metals like arsenic, not iron. Penicillamine is for copper (Wilson's disease). Succimer (E) targets lead. Deferoxamine's high affinity for iron makes it standard for acute toxicity, preventing organ damage (e.g., liver, heart), critical in this pediatric emergency.

A 44-year-old man with acute lymphocytic leukemia is undergoing a multiagent chemotherapy protocol. Agents used include methotrexate. The cycle of medication will last 6 weeks. Which of the following tissues is most likely to experience toxic effects as a result of this therapy?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A 42-year-old woman with a 1-year history of rheumatoid arthritis comes to see you complaining of worsening symptoms. She has been taking leflunomide.
