A client with a cold is taking the antitussive medication benzonatate. Which assessment information indicates to the nurse that the medication is effective?

Choice A reason: Flatulence and nausea are common side effects of azithromycin, which is a macrolide antibiotic that inhibits bacterial protein synthesis. These symptoms are usually mild and transient, and do not require reporting to the health care provider unless they are severe or persistent.

Choice B reason: Urinary frequency is not a relevant symptom of azithromycin, which does not affect urinary function or bladder control. Urinary frequency may be caused by other factors, such as infection, diabetes, or pregnancy.

Choice C reason: Yellow sclera is a serious symptom of azithromycin, which indicates liver damage or jaundice. Azithromycin can cause hepatotoxicity, which is a rare but potentially fatal adverse reaction. Yellow sclera should be reported to the health care provider immediately, as it may require discontinuation of the medication and liver function tests.

Choice D reason: Headache is a common side effect of azithromycin, which is a macrolide antibiotic that inhibits bacterial protein synthesis. This symptom is usually mild and transient, and does not require reporting to the health care provider unless it is severe or persistent.

Choice A reason: Eliminating use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, is an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that stabilizes mood and prevents manic episodes. NSAIDs can increase the blood levels of lithium and cause toxicity, which can manifest as nausea, vomiting, tremors, confusion, or seizures.

Choice B reason: Monitoring blood glucose levels daily is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not affect the blood sugar levels or the risk of diabetes. Blood glucose levels may be important for the general health of the client, but they are not related to lithium therapy.

Choice C reason: Notifying healthcare provider prior to dental procedures is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interact with local anesthetics or antibiotics that may be used during dental procedures. However, the client should inform the dentist about their medical history and medications, as a precaution.

Choice D reason: Avoiding consuming all foods that contain iodine is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interfere with the thyroid function or the metabolism of iodine. Iodine is an essential nutrient that is found in many foods, such as seafood, dairy products, eggs, and iodized salt. Avoiding iodine can cause deficiency and lead to goiter or hypothyroidism.
