A nurse is assessing a client who has increased intracranial pressure. The nurse should recognize that which of the following is the first sign of deteriorating neurological status?

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: Moving the client to a double room may not be effective in preventing wandering and could potentially lead to confusion or agitation if the client is not comfortable with the roommate or the new environment.

Choice B reason: Using a bed alarm is a non-invasive way to alert staff if the client attempts to leave the bed. This can help prevent wandering and ensure the safety of the client without restricting their movement unnecessarily.

Choice C reason: Encouraging participation in activities that provide excessive stimulation is not recommended for clients with dementia, as it can lead to increased confusion, agitation, and potentially exacerbate wandering behaviors.

Choice D reason: The use of chemical restraints, such as sedative medications, should be a last resort and only used when necessary to ensure the safety of the client or others. It is important to use the least restrictive measures first and to always consider the ethical implications of using chemical restraints.
