Which of the following would the nurse emphasize when teaching the client and family about measures to prevent reinfection and the transmission of a parasitic infection to others?

Choice A rationale:

Sulfonamides can increase the risk of crystalluria, which may lead to kidney stones. Adequate fluid intake can help dilute the urine and reduce the risk of crystalluria and kidney stone formation. This is a relevant and appropriate response by the nurse.

Choice B rationale:

Sulfonamides can make the skin more sensitive to sunlight, increasing the risk of sunburn. However, increasing fluid intake is primarily to prevent kidney stone formation, not a reaction to sunlight.

Choice C rationale:

While maintaining adequate hydration does help prevent dehydration, this answer does not directly address the potential side effects or risks associated with sulfonamide use. It is a bit too general and doesn't provide specific information related to the medication.

Choice D rationale:

Sulfonamides can affect blood counts in some cases, but maintaining adequate fluid intake is not primarily related to preventing low blood counts. It's more about mitigating the specific side effects associated with sulfonamide use, such as crystalluria and kidney stones.

Choice A rationale:

Drowsiness is not a common adverse reaction to cephalosporin antibiotics. It is more likely to be associated with medications that have sedative effects.

Choice B rationale:

Headache is a possible adverse reaction to cephalosporins, but it is not a common or specific symptom that the patient needs to report. Headaches are a relatively mild and self-limiting side effect.

Choice C rationale:

Constipation is not a typical adverse reaction to cephalosporin therapy. Gastrointestinal side effects associated with these antibiotics are more commonly diarrhea or nausea. Hypertension (Choice D) is a potential adverse reaction to cephalosporin antibiotics, particularly in patients who are sensitive to changes in blood pressure. It's important for the patient to recognize this symptom and report it promptly, as uncontrolled hypertension can lead to serious health problems. .
