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 C
Explanation
Fluid overload refers to an excess volume of fluid in the body, which can occur as a result of various factors, including excessive fluid intake or inadequate fluid removal. Crackles heard in the lungs, also known as rales, can indicate fluid accumulation in the lungs, a condition known as pulmonary edema. It is a common manifestation of fluid overload and can be detected through auscultation of the lungs.
Weight loss is typically associated with inadequate calorie or nutrient intake, rather than fluid overload.

Correct Answer is C

Explanation
C. Position the client on their left side
The symptoms of feeling dizzy, racing heart, and becoming pale while lying on their back are consistent with supine hypotensive syndrome or vena cava syndrome. This condition occurs when the pregnant uterus compresses the vena cava, reducing blood flow back to the heart and causing a drop-in blood pressure.
Positioning the client on their left side helps alleviate the pressure on the vena cava, allowing for improved blood flow and preventing further symptoms. This position optimizes blood circulation and reduces the risk of complications. The nurse should assist the client in turning onto their left side and ensure they are comfortable.
Providing the client with a glass of orange juice (option A) is not recommended as it may be helpful in cases of low blood sugar or hypoglycemia, but it is not the most appropriate action in this scenario.
Instructing the client to take a brisk walk (option B) is not recommended since physical exertion can further worsen the symptoms and increase the risk of complications.
Checking the client's temperature (option D) is not necessary as the reported symptoms are not indicative of a fever or infection.
Therefore, the most appropriate action for the nurse to take in this situation is to position the client on their left side (option C).
