A nurse is educating a client on self-monitoring blood glucose (SMBG) levels. Which statement by the client indicates a need for further education?

Short-acting insulin is administered before meals to cover postprandial glucose spikes, while long-acting insulin is typically administered once daily, often at bedtime.

Incorrect choices:

a. Administering short-acting insulin in the morning and long-acting insulin at bedtime does not coincide with the timing needed to control glucose levels effectively.

c. Short-acting and long-acting insulins should not be mixed in the same syringe to maintain their proper dosing and actions.

d. Administering long-acting insulin right after a meal would not match the onset and duration of action needed for glucose control.

Subcutaneously. Insulin is typically administered through subcutaneous injections, allowing it to be absorbed into the bloodstream from fatty tissue under the skin.

Incorrect choices:

a. Insulin is a protein and would be broken down in the digestive system if taken orally.

b. Intravenous administration is not commonly used for insulin therapy due to the rapid onset of action and risk of hypoglycemia.

d. Intramuscular administration is not common for insulin therapy because absorption may be unpredictable and could lead to variability in blood glucose control.
