A nurse is caring for a client who has a prescription for NPH insulin 10 units and regular insulin 15 units subcutaneously. After injecting 10 units of air into the NPH insulin vial, which of the following actions should the nurse take next?
Verify the dosage with another nurse.
Inject 15 units of air into the regular insulin vial.
Withdraw 10 units of NPH insulin.
Place the cap over the needle.
The Correct Answer is B
This step is part of the process when mixing NPH and regular insulin in a single syringe. After injecting air into the NPH insulin vial, you should inject an equal amount of air (in this case, 15 units) into the regular insulin vial to maintain pressure balance. This allows for easy withdrawal of the prescribed doses of each insulin type in the same syringe without causing a vacuum in the vials.
After injecting air into the NPH insulin vial (step 1), the nurse should proceed to inject air into the regular insulin vial (step 2) before withdrawing the insulin doses in the subsequent steps.
Verifying the dosage with another nurse is not necessary in this step, as it is done prior to drawing up the insulin. However, it is good practice to have another nurse double-check the dosage before administration.
Injecting air into the regular insulin vial is not required at this stage. It is only necessary when withdrawing the regular insulin dose.
Placing the cap over the needle should be done after withdrawing the desired dose of insulin and before administering it to the client for safety and to prevent needlestick injuries.
The correct sequence when mixing NPH and regular insulin in a single syringe is as follows:
- Inject air into the NPH insulin vial (in this case, 10 units of air).
- Inject air into the regular insulin vial (in this case, 15 units of air).
- Withdraw the prescribed dose of NPH insulin (10 units) from the NPH vial.
- Withdraw the prescribed dose of regular insulin (15 units) from the regular insulin vial.
So, after injecting air into the NPH insulin vial (step 1), the nurse should proceed to inject air into the regular insulin vial (step 2) before withdrawing the insulin doses in the subsequent steps.

Correct Answer is D
Explanation
After a laparoscopic cholecystectomy, steri-strips or adhesive strips are commonly placed over the small incisions. The client should keep the steri-strips in place until they fall off on their own or until they are removed by the healthcare provider during a follow-up visit. Removing the steri-strips prematurely can increase the risk of infection or disrupt the healing process.
"I should eat a high-fat diet for several weeks": After a laparoscopic cholecystectomy, it is important for the client to follow a low-fat diet initially to allow the body time to adjust to the absence of the gallbladder. High-fat foods can be more difficult to digest and may cause digestive discomfort. Gradually introducing small amounts of fat back into the diet is recommended, but a high-fat diet is not appropriate.
"I should expect to have diarrhea until my diet changes": While changes in bowel movements can occur after a cholecystectomy, such as looser stools or changes in frequency, persistent diarrhea is not expected or normal. If the client experiences persistent diarrhea, they should contact their healthcare provider for further evaluation.
"I should expect to have nausea for several days": While some clients may experience mild nausea or discomfort after the surgery, it should generally improve within a few days. If the client experiences persistent or severe nausea, they should contact their healthcare provider.
Correct Answer is B
Explanation
By using short, simple sentences, the nurse can effectively communicate with the client who is exhibiting signs of agitation and anxiety. This communication style can help reduce stress and confusion for the client and promote understanding.
Asking the client if they would like to watch television: While providing options for activities can be beneficial, it is important to address the client's current state of agitation and anxiety before suggesting any specific activities.
Allowing the client to have 1 hour of time alone in their room: While some clients may prefer solitude, in this case, the client's pacing and hand-wringing indicate signs of distress and may require therapeutic interventions rather than isolation.
Moving the client to a table where other clients are playing cards: This option may not address the client's current state of anxiety and pacing. Placing the client in a social setting with other clients might increase their distress and agitation.
