The nurse is assessing the fingernails of a client at the clinic. The nurse observes pitting on the surface of the nail.

What disorder is this finding indicative of?

Choice A rationale

Necrosis is tissue death resulting from prolonged pressure, often a consequence rather than the direct cause of pressure ulcers. The primary cause is sustained pressure impairing blood flow.

Choice B rationale

Low capillary pressure does not directly cause pressure ulcers. They result from sustained external pressure exceeding capillary perfusion pressure, leading to ischemia and tissue damage.

Choice C rationale

Increased mobility actually prevents pressure ulcers by reducing sustained pressure on any one area, enhancing blood flow and tissue health. Immobility is a significant risk factor, not increased mobility.

Choice D rationale

Extrinsic factors like sustained pressure, friction, shear, and moisture contribute directly to pressure ulcer development by compromising skin integrity and blood flow, leading to tissue ischemia and damage.

Choice A rationale

Palpating the client's skin for moisture, temperature, and texture is essential in wound management. This allows the nurse to assess for signs of infection or inflammation, which can affect the wound healing process. Moisture can indicate excessive drainage or sweating that might macerate the skin, while changes in temperature and texture can signify infection or poor blood flow.

Choice B rationale

While asking the client whether the wound bed or surrounding skin itches may provide some information about the client's comfort, it is not a primary intervention for wound management. Itching can be a sign of healing or irritation, but it does not provide direct information on the wound's condition.

Choice C rationale

Measuring and assessing the wound bed, size, edges, and margins are critical steps in wound management. This helps to determine the progression of healing, the presence of necrotic tissue, and any changes in the wound over time. Accurate measurement and documentation are essential for developing an appropriate care plan.

Choice D rationale

Evaluating the client's level of pain using a numeric value pain scale is important in wound management. Pain can indicate underlying issues such as infection, poor perfusion, or neuropathy. Assessing pain helps guide interventions to provide comfort and address any complications that may arise.

Choice E rationale

Reviewing the client's prothrombin time test and international normalized ratio is not a standard intervention for wound management. These tests are more relevant to assessing the client's coagulation status, which may be important for surgical or anticoagulant therapy but not directly for wound care.
