A nurse receives a new prescription from the provider that reads "Give regular insulin 14 units and NPH insulin 28 units subcutaneously at breakfast." How many syringes should the nurse prepare?
__________syringe
The Correct Answer is ["1"]
Both regular insulin and NPH insulin can be mixed in one syringe, as they are compatible. The nurse should draw up regular insulin first (14 units) and then NPH insulin (28 units) to ensure accuracy. Only 1 syringe is required.

Correct Answer is D
Explanation
A. Serum potassium 4.8 mEq/L (3.5 to 5.0 mEq/L): A normal potassium level suggests effective treatment of hyperkalemia.
B. Serum sodium 138 mEq/L (136 to 145 mEq/L): This is within the normal sodium range and unrelated to the adverse effects of insulin therapy.
C. Calcium level of 10.0 mg/dL (9.0 to 10.5 mg/dL): This is within the normal calcium range, unaffected by insulin therapy for hyperkalemia.
D. Serum glucose 58 mg/dL (74 to 106 mg/dL): Hypoglycemia is a potential adverse effect of insulin therapy because insulin drives glucose into cells, lowering blood sugar.
Correct Answer is C
Explanation
A. "I should inject my insulin detemir 30 min before a meal to lower my blood sugar.": Insulin detemir is a long-acting insulin that provides basal glucose control and is not meal-dependent.
B. "If my blood sugar is high, I can mix a dose of regular insulin with my insulin detemir.": Insulin detemir should not be mixed with any other insulin in the same syringe.
C. "I can inject my insulin detemir in the evening before bedtime.": Insulin detemir is commonly administered once daily, and evening administration helps maintain stable glucose levels overnight.
D. "I don't have to worry about hypoglycemia while taking insulin detemir.": While the risk of hypoglycemia is lower with detemir than with some other insulins, it is still possible, particularly if meals are missed or doses are mismanaged.
