A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Administer the insulin within 20 min of preparing it.
Ensure the NPH insulin is drawn into the syringe first.
Inject air into the vial to withdraw the short-acting insulin.
Use two separate syringes to mix the insulin.
The Correct Answer is A
A. Administer the insulin within 20 min of preparing it: When short-acting insulin is mixed with NPH insulin, it should be administered promptly—within 15 to 20 minutes—to ensure the short-acting insulin’s onset is not delayed and the mixture maintains stability.
B. Ensure the NPH insulin is drawn into the syringe first: The short-acting (clear) insulin should be drawn up first, followed by the NPH (cloudy) insulin. Drawing NPH first risks contaminating the short-acting vial with intermediate insulin.
C. Inject air into the vial to withdraw the short-acting insulin: Air should be injected into both vials before withdrawing insulin, but it is essential to inject air into the NPH vial first, then into the short-acting vial, to maintain correct mixing technique.
D. Use two separate syringes to mix the insulin: Separate syringes are not required when mixing compatible insulins. Using one syringe ensures accurate dosing and reduces the number of injections for the client.

Correct Answer is A
Explanation
A. Return the medications to the pharmacy: Expired medications should be returned to the pharmacy or designated medication disposal area to ensure proper handling and prevent accidental administration. Pharmacies follow regulatory guidelines for safe disposal or destruction.
B. Place the medications back in the medication cart: Returning expired medications to the medication cart is unsafe because it risks administration to clients and violates medication safety protocols.
C. Notify the provider about the expired medications: Providers do not need to be notified about expired medications unless it affects a specific prescription; the responsibility for proper disposal lies with the nurse and pharmacy.
D. Flush the medications down the toilet: Flushing medications is generally discouraged due to environmental contamination risks unless specifically recommended for certain drugs. Safe disposal should follow pharmacy or institutional protocols.
Correct Answer is D
Explanation
A. Warmth of the face: Facial flushing or warmth can occur as a common side effect of calcitonin, but alternating nares does not prevent or reduce this reaction. It is typically transient and related to the medication’s vasodilatory effect.
B. Esophagitis: Esophagitis is primarily a concern with oral or injectable forms of certain medications, not intranasal calcitonin. Alternating nares has no impact on esophageal irritation.
C. Dyspnea on exertion: Shortness of breath may indicate an underlying cardiopulmonary issue rather than an intranasal medication effect. Alternating nares does not influence respiratory function.
D. Rhinitis: Rhinitis, or nasal irritation, is a common adverse effect of intranasal calcitonin. Alternating nares daily helps reduce localized irritation and promotes better mucosal recovery, improving comfort and adherence to therapy.
