Final answer:
The most appropriate change for a client with diabetes on a sulfonylurea and metformin experiencing episodes of low blood sugar (hypoglycemia) with a glycated hemoglobin (HbA1c) of 6.5% would be decreasing the dosage of the sulfonylurea.
Step-by-step explanation:
The most appropriate change for a client with diabetes on a sulfonylurea and metformin experiencing episodes of low blood sugar (hypoglycemia) with a glycated hemoglobin (HbA1c) of 6.5% would be d. Decreasing the dosage of the sulfonylurea.
Hypoglycemia can occur as a side effect of sulfonylurea medications, which stimulate the release of insulin from the pancreas. By reducing the dosage of the sulfonylurea, the risk of experiencing low blood sugar episodes can be reduced while maintaining the effectiveness of the treatment.
