A nurse is caring for a client who has a peripherally inserted central catheter (PICC) for the administration of total parenteral nutrition (TPN). The transparent dressing over the insertion site requires replacement. Which of the following actions should the nurse take?
Aspirate the catheter to check for a brisk blood return.
Use sterile technique for the procedure.
Cleanse the insertion site with hydrogen peroxide.
Flush the TPN port with 20 mL of 0.9% sodium chloride.
The Correct Answer is B
Choice A reason: Aspirating the catheter to check for a brisk blood return is not typically recommended as a routine action when replacing the dressing of a PICC line used for TPN. This action is performed to verify patency and placement of the catheter, but it is not directly related to the dressing change procedure.
Choice B reason: Using sterile technique for the procedure is essential when replacing the dressing of a PICC line. Maintaining sterility is crucial to prevent infection, as the PICC line provides direct access to the central venous system. The nurse should use sterile gloves and follow aseptic protocols to minimize the risk of introducing pathogens at the catheter insertion site.
Choice C reason: Cleansing the insertion site with hydrogen peroxide is not recommended for PICC line care. Hydrogen peroxide can be damaging to the tissue and may delay healing. Instead, a chlorhexidine-based antiseptic is typically used to clean the skin around the insertion site during dressing changes to reduce microbial flora and prevent infection.
Choice D reason: Flushing the TPN port with 20 mL of 0.9% sodium chloride is a practice used to maintain catheter patency, but it is not part of the dressing change procedure. Flushing is usually done before and after administering medication or nutrition, not specifically during a dressing change.

Correct Answer is C
Explanation
Choice A reason: Injecting the medication into the abdomen above the level of the iliac crest is not recommended. The preferred sites for subcutaneous injections are the fatty tissue over the triceps, the abdomen from below the costal margin to the iliac crests, and the anterior aspects of the thighs. The area above the iliac crest may not have sufficient subcutaneous tissue, which could affect the absorption of the medication.
Choice B reason: Using a 1-inch needle can be appropriate depending on the client's body mass. For most adults, a 5/8-inch to 1-inch needle is recommended for subcutaneous injections to ensure the medication is delivered to the subcutaneous tissue and not into the muscle.
Choice C reason: Using a 25-gauge needle is the appropriate action when administering heparin subcutaneously. A smaller gauge needle, such as 25-gauge, is typically used for subcutaneous injections to minimize discomfort and tissue trauma.
Choice D reason: Massaging the injection site after administration of the medication is not recommended when administering heparin subcutaneously. Massaging the site can cause the medication to be absorbed more quickly than intended and may increase the risk of bleeding.
Correct Answer is A
Explanation
Choice A reason: White rice is considered a low-potassium food, making it a suitable option for someone with chronic kidney disease who needs to limit their potassium intake. One cup of cooked white rice contains approximately 54 mg of potassium, which is significantly lower than the other options listed.
Choice B reason: Nonfat yogurt can vary in potassium content, but on average, a 1/2 cup serving may contain around 200 to 300 mg of potassium. While it is a nutritious choice, it contains more potassium than white rice and should be consumed in moderation by individuals with potassium restrictions.
Choice C reason: A medium baked potato with skin is high in potassium, with one potato containing over 900 mg of potassium. This makes it an unsuitable choice for someone who needs to limit their potassium intake due to chronic kidney disease.
Choice D reason: Peanut butter contains a moderate amount of potassium. Two tablespoons of peanut butter can have around 150 to 200 mg of potassium. Although it's not as high in potassium as a baked potato, it still contains more potassium than white rice.
