During the skin assessment of a client, the nurse observes a skin lesion that is elevated, round, and filled with serum. Identify the type of lesion.

Choice A rationale

Tachycardia is not a symptom of Cushing's triad; it is often associated with other conditions such as stress or heart problems.

Choice B rationale

Bradypnea is a hallmark of Cushing's triad, indicating decreased respiratory rate due to increased intracranial pressure.

Choice C rationale

Hypertension is a key component of Cushing's triad, caused by increased intracranial pressure leading to elevated blood pressure.

Choice D rationale

Bradycardia, or a slower than normal heart rate, is a symptom of Cushing's triad, resulting from increased pressure in the brain affecting the heart rate.

Choice E rationale

Pupillary constriction is not typically associated with Cushing's triad; it is usually related to other neurological conditions.

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.
