A nurse suspects an older adult is experiencing heat stroke based on which of the assessment findings? (SATA)

Correct Answer:

Lack of sweating

Temperature 105°F

Lowered level of consciousness

Heat stroke is a medical emergency caused by prolonged exposure to high temperatures, resulting in the body's inability to regulate its temperature. The key symptoms include:

Lack of sweating: In heat stroke, the body is unable to sweat effectively, which impairs its ability to cool itself.

Temperature of 105°F: A core body temperature of 105°F (40.6°C) or higher is a hallmark sign of heat stroke.

Lowered level of consciousness: Heat stroke can affect the brain, leading to confusion, delirium, or loss of consciousness.

Why the other options are incorrect:

Increased thirst: Although thirst can occur in heat-related illnesses, it is not a primary sign of heat stroke. In fact, in severe heat stroke, the body may no longer be able to respond appropriately with thirst due to impaired thermoregulation.

Bradypnea: Heat stroke is more likely to cause tachypnea (rapid breathing) rather than bradypnea (slow breathing). The body increases respiratory rate in an attempt to cool down.

Summary:

For an older adult suspected of experiencing heat stroke, the key signs to watch for include lack of sweating, a temperature of 105°F or higher, and a lowered level of consciousness. These findings are indicative of the body’s failure to regulate temperature, requiring immediate medical intervention.
