A nurse is assessing a client who has hypoxia. Which of the following findings should the nurse expect?

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.

Choice A rationale:

Washing hands for 5 to 10 seconds prior to administering medication is indeed an important safety measure, but it is not specifically related to changing or applying a transdermal patch. Hand hygiene is crucial to prevent the spread of infection, but it doesn't directly address the process of applying a patch.

Choice B rationale:

Applying the patch over a non-hairy area within the patient's skin is the correct answer. This is crucial because hair can interfere with the adhesion of the patch, leading to inadequate drug absorption. The rationale behind this is to ensure that the medication is effectively delivered through the skin into the bloodstream without any barriers such as hair. It's also important to choose a site that is clean, dry, and free from cuts or irritation.

Choice C rationale:

Leaving the previous medication patch in place is not recommended. It's essential to remove the old patch before applying a new one to prevent accumulation of the medication and to ensure accurate dosing. Failing to remove the previous patch could lead to an overdose or altered drug effects.

Choice D rationale:

Ensuring that the patient is lying down is not a specific safety measure for changing or applying a transdermal patch. The patient's position doesn't directly impact the effectiveness of the patch or the safety of the application process.
