A nurse is caring for a client who is at risk for pressure injury formation due to immobility. The nurse should place the client in which of the following positions to reduce pressure on the client's bony prominences?

Choice A rationale:

During bladder irrigation, the nurse should instill a specific volume of the prescribed irrigation solution into the bladder to facilitate the removal of clots, mucus, or other debris from the urinary catheter and bladder. The recommended volume to instill is usually 400 to 500 mL, which helps to effectively flush out the bladder without overdistending it.

Choice B rationale:

Clamping the drainage tubing distal to the injection port during bladder irrigation is incorrect. The drainage tubing should remain unclamped to allow the irrigation solution to flow into the bladder and facilitate the removal of debris. Clamping the tubing would prevent the solution from entering the bladder and hinder the irrigation process.

Choice C rationale:

Using a syringe with a 19-gauge needle is not relevant to the process of bladder irrigation. Bladder irrigation is typically performed using a specific irrigation kit that includes appropriate tubing and components, not a syringe and needle.

Choice D rationale:

Withdrawing the irrigation solution into the syringe is not a standard procedure during bladder irrigation. The purpose of bladder irrigation is to instill a specific volume of solution into the bladder and then allow it to drain out, flushing the bladder in the process. Drawing the solution back into a syringe after instillation would disrupt the intended irrigation process.

Choice A rationale:

Using a 5-mL syringe to flush the catheter is not the best choice. Central venous access devices typically require a larger syringe for flushing to prevent excessive pressure and potential damage to the catheter. A smaller syringe like the 5-mL syringe can create higher pressure, which could cause complications.

Choice B rationale:

Changing the site dressing and stabilization device every 24 hours is not the recommended practice. The dressing and stabilization device should be changed according to facility policy and as needed, but a rigid 24-hour schedule is not necessary and might increase the risk of infection due to unnecessary exposure.

Choice C rationale:

Expecting blood to appear in the catheter lumen after flushing is incorrect. Blood in the catheter lumen after flushing could indicate complications such as a dislodged catheter or other issues requiring immediate attention. The catheter should ideally remain patent without the presence of blood.

Choice D rationale:

This is the correct choice. Using chlorhexidine solution to clean the catheter is an evidence-based practice to prevent infection at the insertion site. Chlorhexidine has broad-spectrum antimicrobial properties and helps reduce the risk of catheter-related infections.
