A nurse is completing discharge teaching with a client who has a new diagnosis of AIDS. Which of the following statements by the client indicates an understanding of the teaching?

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: Papilledema, which is the swelling of the optic disc due to increased ICP, is not typically an early sign. It is usually a later manifestation because it takes time for the pressure to build up and affect the optic nerve.

Choice B reason: Restlessness can be an early sign of increased ICP. As ICP begins to rise, it can cause subtle changes in a person's level of consciousness, leading to agitation or restlessness. This is often one of the first signs that healthcare providers notice when monitoring for changes in neurological status.

Choice C reason: Projectile vomiting may occur with increased ICP, but it is not usually an early sign. It tends to occur after other symptoms such as headache and altered consciousness and is more indicative of significant pressure increases that affect the brainstem.

Choice D reason: Decorticate posturing is a severe sign of brain injury associated with increased ICP but is not an early sign. It indicates significant damage to the brain and is a late and ominous sign in the progression of increased ICP.
