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.

a.Artificial flowers are generally considered safer than fresh flowers because they do not harbor water, which can be a source of bacterial growth. However, they can collect dust, which might carry pathogens, though this is typically a lesser concern compared to fresh flowers.
b. Being assigned to a room with negative airflow is actually beneficial for a client with an immunocompromised condition, as it helps prevent the spread of airborne pathogens.
c.Hard boiled eggs do not inherently increase the risk of infection. However, it is important to ensure that all food items are properly prepared, handled, and stored to minimize the risk of foodborne illnesses.
d. Fresh fruit can harbor bacteria and other pathogens on their surfaces, which can pose a significant risk to a neutropenic patient. Even with thorough washing, there is a higher risk compared to cooked or pasteurized foods.
Correct Answer is D
Explanation
Potassium is an essential electrolyte that plays a crucial role in various bodily functions. However, for individuals with an electrolyte imbalance, it is often necessary to limit their potassium intake. Among the options provided, baked chicken breast is the lowest in potassium. Cantaloupe is relatively high in potassium. A cup of diced cantaloupe contains about 430 mg of potassium.
Sweet potatoes are known for their high potassium content. A medium-sized sweet potato with skin contains about 542 mg of potassium.
Orange juice also contains a moderate amount of potassium. An 8-ounce serving of orange juice typically contains around 450 mg of potassium.
Chicken breast is naturally low in potassium compared to fruits and vegetables. It contains about 260 mg of potassium per 4-ounce serving.
Therefore, among the given options, the baked chicken breast is the lowest in potassium and would be the most suitable choice for a client with an electrolyte imbalance requiring a low-potassium diet.
