You receive an order to provide wound care to a patient who has an open abdominal wound, cultured positive for pseudomonas, and want to include PLWS as part of the care plan. The patient is in a semiprivate room with more than 6 feet between the beds and a curtain that can be pulled for privacy. Your approach would be

a. To treat the patient with PLWS with all the protective equipment, plastic tent, and splash shields to prevent aerolosization

b. To request that the patient be moved to a private room before initiating treatment with PLWS

c. To transport the patient to the outpatient department for treatment to avoid treating in a room with curtains.

d. To refuse to treat the patient until the other patient has been discharged.

You are treating a patient daily who will be going to surgery for closure of a traumatic injury in 5–6 days. The wound is 10 cm × 4 cm × 1 cm deep, with no sinuses or undermining, on the posterior thigh. About 40% of the wound is covered with fibrous tissue that requires debriding and there is a moderate amount of drainage. The care plan is to treat daily until surgery. Your best choice of a tip would be

a. Single-use splash shield

b. Divertor splash shield

c. Single-use flexible tracking tip

d. Divertor flexible tracking tip

What is the appropriate approach when treating a patient with multiple wounds?
