When using two insulin pens, the nurse labels them to differentiate which insulin type each contains. This labeling helps ensure which of the following?

• A. Correct timing and action of long-acting versus rapid-acting insulin
• B. That insulin is taken with food only
• C. That insulin is used only in the morning
• D. That insulin is refrigerated at all times

Answer: (A)

Labeling two insulin pens to differentiate their contents helps ensure you administer the right type at the right time. Rapid-acting insulin works quickly to cover meals, while long-acting insulin provides a steady baseline between meals and overnight. If the pens aren’t clearly labeled, there’s a real risk of giving the wrong insulin at the wrong time, which can cause hypoglycemia after a rapid-acting dose or hyperglycemia if a basal dose is missed. Storage considerations (like refrigeration) are important, but labeling specifically supports correct timing and action rather than storage.
