Question

Quizplus · Accepted Answer

Sulfonamides can increase the hypoglycemic effects of oral antidiabetic drugs and insulin, leading to low blood glucose levels. The patient should therefore monitor for symptoms of hypoglycemia, such as shakiness, dizziness, confusion, and increased heart rate. Option B is incorrect because restricting fluids would worsen the patient's urinary tract infection and could lead to dehydration, especially considering the patient has diabetes. Option C is incorrect because sulfonamides should generally be taken with food to decrease gastrointestinal distress. Option D is incorrect because sulfonamides can actually cause hyperkalemia, not sodium loss.
