What would be an appropriate nursing action when assessing a client with severe hypothermia?

Determining the level of consciousness is an appropriate nursing action when assessing a client with severe hypothermia because hypothermia can lead to altered mental status. As the body temperature drops, the central nervous system becomes impaired, which can affect cognitive function and responsiveness. Assessing the level of consciousness helps the nurse evaluate the severity of the hypothermia and guides further interventions, such as the need for rewarming.

In contrast, monitoring for increased heart rate would generally not be relevant, as heart rate may actually decrease in severe hypothermia. Similarly, elevated blood pressure is not typically associated with severe hypothermia; blood pressure may also be low or unstable in such cases. Providing warm fluids orally is not advisable in severe hypothermia because the risk of aspiration and further complications increases when a patient's level of consciousness is impaired, making it unsafe to administer fluids orally.
