The nurse is changing the subclavian dressing of a client who is receiving total parenteral nutrition. When assessing the catheter insertion site, the nurse noticed the presence of a yellow drainage from around the sutures that are anchoring the catheter. Which actions should the nurse take first?
Administer a broad-spectrum antibiotic to prevent infection.
Notify the healthcare provider immediately and wait for further instructions.
Obtain a culture specimen of the drainage, apply a sterile dressing over the site, and monitor for any signs of infection.
Remove the sutures immediately to prevent further drainage.
The Correct Answer is C
A. Administering a broad-spectrum antibiotic is not the first action in this case. The first priority is to assess the situation and obtain a culture of the drainage to identify any infection before initiating antibiotics.
B. While notifying the healthcare provider is important, it is more important to take an initial action by obtaining a culture specimen. Waiting without taking action could delay appropriate care.
C. The best first action is to obtain a culture of the drainage to identify any potential infection, apply a sterile dressing, and continue to monitor the site for further signs of infection. Culturing the drainage helps guide the appropriate treatment.
D. Removing the sutures is not the appropriate action. The sutures should not be removed unless there is clear indication, as this could disrupt the integrity of the catheter placement.

Correct Answer is D
Explanation
A. 3% sodium chloride is a hypertonic solution used to treat severe hyponatremia and should not be used as a substitute for TPN.
B. Lactated Ringer's is an isotonic solution typically used for fluid resuscitation, but it lacks the necessary components (glucose, amino acids) that are found in TPN.
C. 0.9% sodium chloride is an isotonic saline solution and can be used for hydration, but it does not provide the calories and nutrients that the client is receiving through TPN.
D. Dextrose 10% in water is the best choice in this scenario. It provides glucose for energy and can help maintain blood sugar levels until the next TPN solution is available. It is commonly used as a temporary substitute for TPN to prevent hypoglycemia.
Correct Answer is A
Explanation
A. The IV tubing for TPN should be changed every 24 hours to prevent infection, as TPN is a high-risk solution for bacterial growth due to its high glucose content. Regular changes help reduce the risk of contamination and complications such as bloodstream infections.
B. The IV site dressing should be changed at least every 48 to 72 hours (or per institutional policy) to maintain aseptic technique and minimize infection risk. Changing the dressing every 4 days may exceed this timeframe and increase the risk of infection.
C. Weighing the client is important to monitor fluid balance, but daily weighing is more typical than every other day for clients receiving TPN. This helps to assess nutritional status and detect potential fluid overload or deficit.
D. Blood glucose levels should be monitored more frequently, typically every 6 hours, because TPN can cause significant fluctuations in blood glucose. Checking every 12 hours would not be adequate for early detection of hyperglycemia or hypoglycemia.
