The nurse is planning to administer a tuberculin test to a client with a 27-gauge, 5/8-inch needle. What angle will the nurse insert the needle?

A. Capillary refill is less than 2 seconds: A rapid capillary refill indicates good peripheral perfusion, which reduces the risk of tissue ischemia and pressure injury. This finding reflects normal circulatory function and is not a risk factor for PI formation.

B. Fecal incontinence: Fecal incontinence increases the risk of pressure injury because moisture, enzymes, and bacteria from stool can macerate the skin, impairing its integrity. Combined with immobility or pressure over bony prominences, incontinence significantly contributes to skin breakdown and PI development.

C. A raised red rash on the right shin: While a rash may indicate irritation or dermatitis, it is a localized skin condition and does not automatically reflect a generalized risk for pressure injuries. Pressure injuries are primarily associated with sustained pressure, friction, shear, and moisture over bony prominences.

D. Ate two thirds of breakfast: Nutritional intake is important for skin integrity, but consuming most of a meal indicates adequate intake rather than a risk factor. Malnutrition or insufficient caloric/protein intake would increase PI risk, but this observation alone does not.

A. Full thickness skin loss of the subcutaneous tissue: Stage 3 pressure injuries involve full-thickness loss of the skin extending through the dermis into the subcutaneous tissue. The subcutaneous fat may be visible, and the depth of the wound varies by anatomical location, making this a defining characteristic of Stage 3 injuries.

B. A deep purplish area is noted: A deep purplish or maroon area is more characteristic of a suspected deep tissue injury rather than a Stage 3 pressure injury. These injuries involve underlying tissue damage beneath intact or minimally broken skin and may not involve full-thickness loss of subcutaneous tissue at this stage.

C. A shallow wound bed is present: Shallow wounds are typical of Stage 2 pressure injuries, which involve partial-thickness loss of dermis and present as open, superficial ulcers. Stage 3 wounds are deeper and extend through the full thickness of the skin into subcutaneous tissue.

D. No visible bone, tendon, and ligaments are noted: In Stage 3 pressure injuries, the bone, tendon, or muscle is not exposed. The injury extends into subcutaneous tissue but stops short of deeper structures, distinguishing it from Stage 4 pressure injuries.

E. Visible bone, tendon, and ligaments are noted: Exposure of bone, tendon, or ligaments indicates a Stage 4 pressure injury, which involves full-thickness tissue loss with damage extending into underlying structures. This finding exceeds the depth seen in Stage 3 injuries.
