Which of the following is a common side effect of diabetes medications that the nurse should monitor?

Hypoglycemia is a common side effect of several diabetes medications, particularly insulin and certain oral hypoglycemic agents like sulfonylureas. When these medications work to decrease blood glucose levels, there is a risk that they may lower them too much, leading to hypoglycemia. Symptoms of hypoglycemia can include shakiness, sweating, confusion, irritability, and even loss of consciousness if blood sugar levels drop dangerously low.

Monitoring for hypoglycemia is crucial for patients on these medications, as timely intervention can prevent more severe complications. The nurse must educate patients on recognizing the symptoms of hypoglycemia and the importance of regular blood sugar monitoring, especially when starting new medications or adjusting doses.

Although other options like weight gain and gastrointestinal issues can be concerns with specific medications, hypoglycemia is particularly critical due to its immediate and potentially life-threatening consequences.
