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: Instructing the client to expect tingling in their extremities is not a standard post-lumbar puncture care instruction. Tingling may be a sign of nerve irritation or damage, which is not an expected outcome and should be reported if it occurs.

Choice B reason: Measuring blood glucose every 2 hours is not related to post-lumbar puncture care unless the client has a specific condition that requires such monitoring. Post-lumbar puncture care focuses on preventing complications such as headaches and monitoring for signs of infection or bleeding.

Choice C reason: Limiting the client's fluid intake is not advised following a lumbar puncture. In fact, increasing fluid intake can help prevent the occurrence of post-lumbar puncture headaches, which are a common complication. Adequate hydration helps replenish cerebrospinal fluid and reduce headache severity.

Choice D reason: Instructing the client to lie flat is the correct action. After a lumbar puncture, it is recommended that the client lies flat for several hours to prevent the leakage of cerebrospinal fluid from the puncture site, which can lead to a spinal headache. Lying flat helps maintain normal cerebrospinal fluid pressure and reduces the risk of headache.

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.
