A nurse is preparing to mix short-acting and intermediate-acting insulin in one syringe to administer to a client who has type 1 diabetes mellitus. Identify the sequence the nurse should follow. (Move the steps into the box on the right, placing them in the selected order of performance. Use all the steps.)

Draw up a volume of air equal to the volume of insulin from the intermediate-acting insulin vial.

Inject the volume of air equal to the amount of insulin to withdraw from the intermediate-acting insulin vial.

Inject the volume of air equal to the insulin dose from the short- acting insulin vial.

Withdraw the prescribed amount of insulin from the short-acting insulin vial.

Withdraw the prescribed amount of insulin from the intermediate-acting insulin vial.

Answer and Explanation

The Correct Answer is A,C,D,B,E

A. Draw up a volume of air equal to the volume of insulin from the intermediate-acting insulin vial. Air is first drawn into the syringe for the intermediate-acting insulin to prevent creating a vacuum when withdrawing it later.

C. Inject the volume of air equal to the insulin dose from the short-acting insulin vial. Injecting air into the short-acting vial prevents vacuum formation and makes withdrawal easier.

D. Withdraw the prescribed amount of insulin from the short-acting insulin vial. The short-acting insulin is withdrawn first to avoid contaminating it with intermediate-acting insulin.

B. Inject the volume of air equal to the amount of insulin to withdraw from the intermediate-acting insulin vial. Air is injected into the intermediate-acting vial before withdrawal to facilitate drawing up the insulin.

E. Withdraw the prescribed amount of insulin from the intermediate-acting insulin vial. Finally, the intermediate-acting insulin is withdrawn, completing the mixture in the syringe.

Correct Answer is C

Explanation

A. Change the secondary IV infusion set twice weekly: Secondary IV sets, such as piggyback infusions, should generally be changed every 24 hours to reduce the risk of contamination and infection. Changing them twice weekly would not maintain proper asepsis.

B. Change a continuously infusing IV bag after 48 hr: Continuous IV bags should be replaced at least every 24 hours to prevent bacterial growth. Waiting 48 hours increases the risk of microbial contamination and bloodstream infections.

C. Change the primary IV infusion set every 96 hr: Changing the primary IV infusion set every 96 hours (4 days) aligns with standard infection-control guidelines. This interval helps maintain asepsis while minimizing the risk of IV-related infections.

D. Change the extension tubing once per week: Extension tubing connected to the IV line should be changed more frequently, typically every 72 to 96 hours, to prevent contamination. Once per week is too infrequent and increases infection risk.

A. Wear an N95 mask when caring for the client. B. Place the client in a private room. C. Place the client on droplet isolation precautions. D. Assign client to a negative air pressure room. E. Ensure the client wears a mask when outside their room.

Correct Answer is ["B","C","E"]

Explanation

A. Wear an N95 mask when caring for the client: An N95 mask is necessary for airborne infections such as tuberculosis or measles. Pneumonia caused by typical bacteria or viruses is spread by droplets, so a surgical mask is sufficient, not an N95.

B. Place the client in a private room: Clients with pneumonia should be placed in a private room to prevent transmission of infectious droplets to others, especially those who are immunocompromised or at higher risk for respiratory infections.

C. Place the client on droplet isolation precautions: Pneumonia spreads through large respiratory droplets from coughing or sneezing. Droplet precautions include wearing a surgical mask within 3 feet of the client and limiting close contact exposure.

D. Assign client to a negative air pressure room: A negative air pressure room is required for airborne precautions, not droplet infections like pneumonia. It is unnecessary and would reserve specialized rooms for conditions requiring them.

E. Ensure the client wears a mask when outside their room: Having the client wear a surgical mask while leaving the room helps contain respiratory secretions and prevents droplet transmission to others in hallways or procedure areas.
