The nurse notes that a patient has a black pressure ulcer on the left hip. Which event will the nurse anticipate when planning care for this patient?

Step 1 is: To find out how many mL/hr the nurse should set the infusion pump to deliver, we need to divide the total volume of enteral nutrition (840 mL) by the total time (24 hours).

So, the calculation is: 840 mL ÷ 24 hours = 35 mL/hr Therefore, the nurse should set the infusion pump to deliver 35 mL/hr.

Choice A rationale: Wet-to-dry dressings are a form of mechanical debridement. This method involves applying a wet dressing to the wound and allowing it to dry. When the dressing is removed, it also removes some of the dead or damaged tissue from the wound, helping to clean the wound and promote healing. This method can be painful and is not selective, meaning it can also remove healthy tissue. However, it is often used for wounds with a large amount of debris or necrotic tissue.

Choice B rationale: Surgical debridement is another method of wound debridement, but it is not a form of mechanical debridement. This method involves using surgical instruments to remove dead or damaged tissue. It is the fastest method of debridement and is often used for wounds that are infected or have a large amount of necrotic tissue. However, it requires a skilled practitioner and can be painful.

Choice C rationale: Enzymatic debridement involves applying a topical ointment that contains enzymes to the wound. These enzymes help to break down dead or damaged tissue. This method is selective and only removes necrotic tissue, leaving healthy tissue intact. However, it is not a form of mechanical debridement.

Choice D rationale: Autolytic debridement is a method that uses the body’s own enzymes and moisture to break down dead or damaged tissue. This is the slowest method of debridement but is also the least painful and is selective for necrotic tissue. Like enzymatic debridement, autolytic debridement is not a form of mechanical debridement.
