The nurse determines a teaching session about chloroquine is successful when the client correctly articulates which factor? A) Avoid foods that acidify the urine. B) Take the drug on an empty stomach. C) Increase dosage if dosage missed once. D) Discontinue drug if color of urine changes. Answer: A Rationale: The nurse should educate the client to avoid foods that acidify the urine (cranberries, plums, prunes, meats, cheeses, eggs, fish, and grains), as they may interact with the antimalarial drug and increase excretion and thereby decrease the effectiveness of chloroquine while taking the drug. Taking the drug on an empty stomach is not advisable for antimalarial drugs. The nurse should instruct the client to adhere to the dosage regimen unless instructed otherwise. Yellow or brownish discoloration of the urine during chloroquine treatment is normal; there is no need to discontinue the therapy.
