Question

Quizplus · Accepted Answer

Sulfonylurea antidiabetic drugs can lower blood glucose levels and may potentiate the hypoglycemic effect of TMP-SMX. The nurse should monitor the patient for signs and symptoms of hypoglycemia, such as confusion, diaphoresis, and tremors. There is no indication that this medication combination would cause headaches, hypertension, or superinfection.
