Answer to Question 1

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.

Answer to Question 2

ANS: B
According to the algorithm for selecting the correct humidity and bland aerosol therapy, a heated humidifier is appropriate for this patient. Both the use of an uncuffed endotracheal tube and the presence of thick, bloody secretions are contraindications for the use of a heat and moisture ex-changer. Heat and moisture exchangers cannot be used with heated humidification. Systemic hydration does not adequately humidify inhaled gas.
