What does it mean if the skin is described as "mottled"?

Describing skin as "mottled" refers to the appearance of irregular patches of color on the skin, often resulting from poor circulation. This mottling can occur due to various conditions that affect blood flow, such as shock, hypothermia, or other circulatory issues. It indicates that the skin is not receiving adequate blood supply uniformly, which may lead to significant health concerns. Recognizing mottled skin is crucial for EMTs because it serves as a visual cue that the patient may be experiencing a serious underlying condition that requires immediate medical attention.

The other choices do not accurately describe the condition associated with mottled skin. Normal circulation would not result in a mottled appearance, a healthy glow implies proper blood flow and oxygenation, and while medications can cause changes in skin appearance, mottling specifically signifies impaired circulation rather than a reaction to medication.
