The nurse in the trauma unit has received a report on a client who has multiple injuries following a motor vehicle crash. Which of the following actions should the nurse plan to take first?

Choice A rationale:

This choice is not correct because verifying the oxygen flow rate every other day is not part of the discharge teaching for a client on home oxygen therapy. The flow rate should be checked regularly, not just every other day, to ensure the client's safety and well-being.

Choice B rationale:

This choice is correct. Checking the tops of the ears for skin breakdown is important in a client using a nasal cannula for oxygen therapy. Prolonged use of the cannula can lead to irritation and pressure-related skin breakdown behind the ears.

Choice C rationale:

This choice is correct. Posting "no smoking signs in a prominent location in the home" is an important safety measure for a client on oxygen therapy. Oxygen supports combustion, and smoking in the presence of oxygen can lead to fire hazards.

Choice D rationale:

This choice is correct. Checking the cannula position on a regular basis is essential to ensure that the oxygen is being delivered effectively and that the client is not experiencing discomfort or skin breakdown due to improper positioning.

Choice E rationale:

This choice is correct. Applying petroleum ointment to the nares if they become dry and irritated is a suitable intervention to maintain the client's comfort and prevent skin irritation from the cannula.

The correct answer is choice B. Necrotic subcutaneous tissue.

Choice A rationale:

Partial-thickness skin loss (Choice A) is characteristic of a stage II pressure ulcer, not a stage III ulcer. A stage II pressure ulcer involves the loss of the epidermis and possibly the dermis, resulting in a shallow open ulcer with a red-pink wound bed.

Choice B rationale:

Necrotic subcutaneous tissue is a manifestation of a stage III pressure ulcer. A stage III ulcer involves full-thickness skin loss where subcutaneous fat may be visible, but exposed bone or muscle is not yet present. Necrotic tissue in the wound bed indicates a more advanced level of tissue damage and the need for appropriate wound care to promote healing.

Choice C rationale:

Blood-filled blisters (Choice C) are not specific to pressure ulcers and are more commonly associated with friction or shear forces. These blisters are not indicative of a stage III pressure ulcer, which involves visible full-thickness tissue loss.

Choice D rationale:

Exposed bone (Choice D) is a characteristic of a stage IV pressure ulcer, not a stage III ulcer. A stage IV ulcer involves extensive tissue loss with exposure of muscle, tendon, or bone. This represents a severe level of tissue damage and requires intensive wound care and management.
