A nurse is caring for a client who has a prescription for 5 units of regular insulin and 10 units of NPH insulin to be mixed together and administered subcutaneously.
Determine the correct order of steps for this procedure.
Inject 5 units of air into the bottle of regular insulin.
Withdraw the correct dose of NPH insulin from the bottle.
Inject 10 units of air into the bottle of NPH insulin.
Withdraw the correct dose of regular insulin from the bottle.
The Correct Answer is C,A,D,B
Choice A rationale
Injecting 5 units of air into the bottle of regular insulin is the second step in the procedure. This is done after injecting air into the NPH insulin bottle. The purpose of this step is to pressurize the vial, making it easier to withdraw the insulin.
Choice B rationale
Withdrawing the correct dose of NPH insulin from the bottle is the last step in the procedure. This is done after withdrawing the regular insulin to prevent contamination of the regular insulin with the NPH insulin.
Choice C rationale
Injecting 10 units of air into the bottle of NPH insulin is the first step in the procedure. This is done before injecting air into the regular insulin bottle. The purpose of this step is to pressurize the vial, making it easier to withdraw the insulin.
Choice D rationale
Withdrawing the correct dose of regular insulin from the bottle is the third step in the procedure. This is done after injecting air into the regular insulin bottle and before withdrawing the NPH insulin. The purpose of this step is to ensure that the correct dose of regular insulin is administered.

Correct Answer is B
Explanation
Choice A rationale
Carrying a patient’s soiled linens out of the room in a mesh linen bag is not the most effective way to prevent the spread of infection. While it’s important to handle soiled linens properly to avoid contaminating oneself or the environment, this action alone does not have a significant impact on preventing the spread of infection among a group of patients.
Choice B rationale
Placing a patient who has tuberculosis in a room with negative-pressure airflow is a key measure in preventing the spread of this airborne infection. Negative-pressure rooms prevent
contaminated air from escaping the room and spreading to other areas, thereby protecting other patients and healthcare workers.
Choice C rationale
Providing disposable plates and utensils for a patient who is HIV-positive is not necessary for preventing the spread of infection. HIV is not transmitted through casual contact or through sharing food or utensils.
Choice D rationale
Disposing of a patient’s blood-saturated dressing in a trash bag inside a second trash bag is a good practice for handling biohazardous waste, but it is not the most effective measure for preventing the spread of infection among a group of patients.
Correct Answer is C
Explanation
Choice A rationale
Inserting the needle at a 15-degree angle is not recommended for subcutaneous injections like heparin. The needle should be inserted at a 90-degree angle.
Choice B rationale
Aspirating for blood return before administration is not necessary when administering heparin.
Choice C rationale
Heparin should be administered into the abdominal fat layer, above the iliac crest and at least 2 inches away from the umbilicus.
Choice D rationale
Massaging the site after the injection is not recommended as it can cause bruising.
