A nurse cares for a client with diabetes mellitus who is visually impaired. The client asks, "Can I ask my niece to prefill my syringes and then store them for later use when I need them?" How should the nurse respond?
a. "Yes. Prefilled syringes can be stored for 3 weeks in the refrigerator in a vertical position with the needle pointing up."
b. "Yes. Syringes can be filled with insulin and stored for a month in a location that is protected from light."
c. "Insulin reacts with plastic, so prefilled syringes are okay, but you will need to use glass syringes."
d. "No. Insulin syringes cannot be prefilled and stored for any length of time outside of the container."
ANS: A
Insulin is relatively stable when stored in a cool, dry place away from light. When refrigerated, prefilled plastic syringes are stable for up to 3 weeks. They should be stored in the refrigerator in the vertical position with the needle pointing up to prevent suspended insulin particles from clogging the needle.
