Which of the following indicates that a patient may be experiencing Hypothermia?

Vasoconstriction is a physiological response that occurs when the body is exposed to cold temperatures. In an effort to conserve heat, the blood vessels constrict, reducing blood flow to the extremities and peripheral tissues, which helps to maintain the core body temperature. This response is typically accompanied by other symptoms of hypothermia such as shivering, cold skin, and, in some cases, confusion.

Other options do not align with the clinical indicators of hypothermia. For example, high blood pressure is usually not a direct sign of hypothermia; rather, it can occur in other states of physiological stress. Deep breathing tends to occur as a response to various conditions but is not specific to hypothermia. Excessive sweating usually indicates overheating rather than a body trying to conserve warmth, making it more characteristic of hyperthermia rather than hypothermia. Therefore, vasoconstriction serves as a clear indicator that a patient is likely experiencing hypothermia.
