Which of the following treatments would provide sufficient humidity to a conscious patient with a core temperature less than 36° C who had nearly drowned?
a. Heat and moisture exchanger c. Heated aerosol with humidifier
b. Heated aerosol or humidifier d. Systemic hydration
ANS: B
Because the patient is hypothermic, a heated aerosol or heated humidifier needs to be used. Hy-pothermia is a contraindication for the use of a heat and moisture exchanger. Heated aerosol generators are not used in conjunction with humidifiers, and systemic hydration will not help warm the patient's core temperature.
