A 14-year-old adolescent with type 1 diabetes checks his blood glucose level at 9:00 p.m. (2100) before going to bed. It has been 4 hours since his dinner and his regular insulin dose. His blood glucose level is 60 mg/dl (3.3 mmol/L), and he states that he feels a little shaky. What should the nurse suggest?
A. Doing nothing because the glucose level is unreliable because the adolescent measured it himself
B. A bedtime snack of an 8-oz (240 mL) glass of milk and graham crackers with peanut butter
C. Going to sleep to decrease the metabolic demands on the body
D. Taking a dose of glucagon
