When assessing a client's respiratory status, which technique should the practical nurse use to assess the anterior-posterior (AP) chest diameter?

Rationale:

A. Offer the client fluids and a high protein snack: Adequate hydration and nutrition are important for skin integrity and wound prevention, but these measures do not immediately identify whether the reddened area represents a developing pressure injury. They are supportive interventions rather than diagnostic actions.

B. Compare range of motion of the client's legs: Assessing joint mobility is important for overall musculoskeletal health and preventing contractures, but it does not provide direct information about skin perfusion or the severity of a reddened area caused by pressure.

C. Determine the ability of the tissue to blanch: Assessing blanchability is the primary method for evaluating early pressure injuries. If the redness blanches when gentle pressure is applied and returns to normal color, it indicates reactive hyperemia. Non-blanchable redness suggests potential Stage 1 pressure injury, requiring prompt intervention to prevent further tissue damage.

D. Assess elasticity of the surrounding tissue: Tissue turgor or elasticity provides information about hydration status but does not indicate whether the reddened area is a pressure-related injury. While useful for overall assessment, it is not the priority action when identifying early skin breakdown

Rationale:

A. Purulent drainage: The presence of pus or purulent exudate is a hallmark sign of infection. It indicates an active inflammatory response to bacterial invasion and is often accompanied by odor, discoloration, and consistency changes, signaling that the wound is not healing properly.

B. Scar tissue: Scar tissue represents healed or healing tissue and is a normal part of the wound repair process. It does not indicate an active infection and typically develops after the inflammatory and proliferative phases of healing have been completed.

C. Streaking: Red streaks radiating from the wound suggest lymphangitis, which is a sign of systemic spread of infection. This finding, combined with systemic symptoms such as chills or fever, indicates that the infection may be progressing and requires immediate clinical attention.

D. Granulated tissue: Healthy granulation tissue is pink or red, moist, and composed of new capillaries and connective tissue. It is a positive indicator of wound healing and does not signify infection.

E. Increased redness: Erythema around a wound signals localized inflammation and may reflect infection. When accompanied by warmth, swelling, or pain, increased redness is an important clinical finding suggesting an inflammatory or infectious process.
