An agitated, confused female client arrives in the emergency department. Her history includes type 1 diabetes mellitus, hypertension, and angina pectoris. Assessment reveals pallor, diaphoresis, headache, and intense hunger. A stat blood glucose sample measures 42 mg/dl, and the client is treated for an acute hypoglycemic reaction. After recovery, the nurse teaches the client to treat hypoglycemia by ingesting: 
Select and explain. 
A. 2 to 5 g of a simple carbohydrate, B. 10 to 15 g of a simple carbohydrate., C. 18 to 20 g of a simple carbohydrate., D. 25 to 30 g of a simple carbohydrate.
B: 10 to 15 g of a simple carbohydrate.
Answer: B: 10 to 15 g of a simple carbohydrate. 
Explanation: To reverse hypoglycemia, the American Diabetes Association recommends ingesting 10 to 15 g of a simple carbohydrate, such as three to five pieces of hard candy, two to three packets of sugar (4 to 6 tsp), or 4 oz of fruit juice. If necessary, this treatment can be repeated in 15 minutes. 
Ingesting only 2 to 5 g of a simple carbohydrate may not raise the blood glucose level sufficiently. Ingesting more than 15 g may raise it above normal, causing hyperglycemia.
