The nurse is preparing to administer 1 liter (1000 mL) of 0.9% NS over 2 hours intravenously to a patient experiencing shock. At what rate will the nurse set the infusion pump? Enter the number only.

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.

Choice A reason: Including more cantaloupe in the diet is a good practice for a client on furosemide therapy. Cantaloupe is high in potassium, and furosemide can cause hypokalemia (low potassium levels) as it is a potent diuretic that increases urine production and the excretion of various electrolytes, including potassium. Therefore, consuming foods rich in potassium can help counteract this potential adverse effect.

Choice B reason: Checking the pulse before taking the medication is a general safety measure but does not directly relate to a specific adverse effect of furosemide. While it's important to monitor heart rate, especially in clients with heart failure, this statement does not reflect an understanding of the adverse effects related to furosemide.

Choice C reason: Trying to limit foods that contain salt is an appropriate action for a client with heart failure but is not directly related to an adverse effect of furosemide. Reducing salt intake can help manage heart failure by preventing fluid retention; however, it does not address the specific adverse effects of furosemide therapy.

Choice D reason: Checking blood pressure to ensure it doesn't get too high is important for clients with heart failure but does not indicate an understanding of the adverse effects of furosemide. Furosemide is used to reduce excess fluid in the body, which can lower blood pressure, not increase it. This statement does not reflect an understanding of furosemide's potential to cause electrolyte imbalances.
