Despite coaching and explaining the benefits of a nonrebreather face mask, a moderately short of breath and hypoxic patient with lung cancer states that she cannot tolerate the mask over her face. The more that she panics, the worse the shortness of breath becomes. Your best course of action is to:

A) remove the nonrebreather mask and apply a simple face mask. B) decrease the oxygen flow rate entering the nonrebreather face mask. C) disconnect the nonrebreather and replace it with a nasal cannula. D) discontinue oxygen therapy and continually monitor breath sounds during transport.

You appropriately size a nasopharyngeal airway by measuring the:

a. distance from the patient's mouth to the angle of the jaw. b. diameter of the patient's larger nostril. c. distance from the patient's nose to the earlobe. d. diameter of the patient's little finger.
