A nurse is assisting with preparing a client who is to have a central venous catheter inserted for the administration of total parenteral nutrition (TPN). Which of the following actions should the nurse take?
Verify the amount of TPN solution the client is receiving every 4 hr.
Prepare the client for a chest x-ray to verify catheter placement.
Use clean technique when changing the catheter dressing.
Place the client in Sims' position for catheter insertion.
The Correct Answer is B
When a central venous catheter (CVC) is inserted, it is essential to confirm proper catheter placement to ensure safe and effective administration of TPN and other medications. A chest x-ray is the gold standard method to verify the correct positioning of the CVC tip. It helps determine if the catheter is appropriately positioned in the superior vena cava or another desired location, which minimizes the risk of complications such as pneumothorax or improper medication delivery.

The other options listed are not appropriate actions for the nurse to take in this situation:
- Verifying the amount of TPN solution the client is receiving every 4 hours is a task related to ongoing monitoring of TPN administration, but it is not directly related to the preparation of the client for CVC insertion.
- Using clean technique when changing the catheter dressing is not appropriate for CVC insertion. Sterile technique is required during the insertion of a CVC to minimize the risk of infection.
- Placing the client in Sims' position is not the appropriate position for CVC insertion. The client is typically placed in a supine or Trendelenburg position during the procedure to facilitate access to the central venous system.

Correct Answer is D
Explanation
Explanation
D, Wash hands with soap and water for 20 seconds
Hand hygiene is a critical practice in preventing the transmission of infections in healthcare settings. Here's why the other options are incorrect:
Wearing sterile gloves when in contact with body fluids in (option A) is incorrect because it is important for preventing the transmission of pathogens, but it is not directly related to hand hygiene. Hand hygiene refers to the cleaning of hands to remove pathogens, and sterile gloves provide a barrier to protect the healthcare worker and the patient.
B. Using an alcohol-based cleanser when hands are visibly soiled in (option B) is not recommended. Alcohol-based cleansers are effective in killing many types of germs, but they are not as effective in removing visible dirt, blood, or body fluids. In such cases, it is important to wash hands with soap and water to thoroughly clean them.
Artificial nails should not be worn when performing direct client care in (option C). They can harbor and transmit pathogens and make it more difficult to effectively clean hands. The Centres for Disease Control and Prevention (CDC) recommends that healthcare workers maintain short, clean, and natural nails without the use of artificial nails or nail extensions.
Correct Answer is B
Explanation
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.
