The health care provider prescribes core warming methods for a conscious client with severe hypothermia. What equipment should the nurse obtain?

Rationale: A. This method (bladder or gastric lavage with warmed fluids) is considered a core rewarming technique, but it is invasive and typically reserved for unconscious or severely unstable clients. It is not the first choice for a conscious client who can still regulate airway and tolerate noninvasive warming. B. While warmed, humidified oxygen can help raise body temperature, the bag-valve-mask is primarily for respiratory support in clients who are not breathing adequately. A conscious client with stable breathing usually does not need this equipment. C. This is an invasive, high-risk method used only in extreme hypothermia with cardiac instability or failure. It is not appropriate for a conscious client who can be managed with less invasive methods. D. For a conscious client with severe hypothermia, external warming methods such as warm blankets, heating pads, or forced-air warming devices are the safest and most effective first-line interventions. They allow gradual, controlled warming while maintaining comfort and safety, and they reduce the risk of complications such as arrhythmias that can occur with rapid core warming.
