The nurse is assessing a client following removal of a cast of the left lower leg. The cast had been in place for six weeks. Which assessment finding(s) of the left leg does the nurse anticipate identifying?

A. intact blister. A Stage 2 pressure injury presents as partial-thickness loss of the dermis or as a serum-filled bulla. The epidermis may be non-intact or appear as a tense, fluid-filled structure without deeper tissue involvement. This stage is characterized by a pink, painful wound bed without evidence of necrotic tissue.

B. undermining. This clinical finding involves the destruction of tissue under the intact skin along the wound margins, typically seen in Stage 3 or 4 injuries. Stage 2 lesions are superficial and do not extend into the subcutaneous fat or deeper fascia. The presence of such cavities indicates a more advanced degree of tissue destruction.

C. presence of slough. The identification of yellow, tan, or green devitalized tissue excludes the diagnosis of a Stage 2 injury by definition. Slough indicates a full-thickness wound where the depth of the injury is obscured by inflammatory exudate. Stage 2 wounds are defined by a clean, red-to-pink viable wound bed.

D. blanchable erythema. Skin that turns pale upon the application of pressure represents a reactive hyperemic response rather than a structural injury. This physiological state indicates intact microcirculation and does not meet the criteria for a pressure injury. Stage 2 involves a break in the skin or a persistent blister.

E. presence of granulation tissue. This beefy red, granular substance appears during the proliferative phase of healing in full-thickness wounds. Since Stage 2 injuries only involve the epidermis and partial dermis, they heal by re-epithelialization rather than the formation of granulation tissue. Its presence suggests a deeper, Stage 3 or 4 ulcer.

A. Arterial ulcer: These ulcers result from inadequate blood supply and are characterized by a lack of drainage and intense pain that is exacerbated by elevation. The "copious amounts of drainage" described in the question is the exact opposite of the dry, necrotic appearance typical of arterial insufficiency. They require gravity-dependent positioning for comfort.

B. Venous ulcer: Chronic venous insufficiency leads to high hydrostatic pressure, which forces fluid into the interstitial space, resulting in heavy exudate or "copious drainage." Elevating the leg reduces this pressure and facilitates venous return, which directly relieves the associated aching pain. These findings are classic diagnostic indicators for venous etiology.

C. Unstageable pressure injury: This classification is reserved for wounds where the base is completely covered by slough or eschar, making depth determination impossible. It does not describe the vascular or exudative characteristics of the wound. The description provided focuses on physiological symptoms rather than the visual obstruction of the wound bed.

D. Stage 3 pressure injury: This stage involves full-thickness skin loss where subcutaneous fat may be visible, but bone or tendon is not. While a Stage 3 injury can have drainage, the specific relief of pain with elevation is a systemic vascular finding rather than a characteristic of localized pressure damage. It lacks the defining features of venous stasis.
