Answer to Question 1

ANS: A
A. Correct response: A number of studies have revealed that manual ventilation with a self-inflating bag during patient transport can lead to unintentional respiratory alkalosis. In these studies episodic hypotension and cardiac dysrhythmias were associated with a rapid decrease in Paco2 and the corresponding respiratory alkalosis. Overventilation of the patient would induce a respiratory alkalosis. Therefore the therapist must be concerned with not hyperventilating the patient.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A

Answer to Question 2

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Transport ventilators are typically simple devices having one or two controls, providing only one mode, no PEEP, and strictly an Fio2 of 1.0. The AHA has suggested that automatic transport ventilators meet the criteria for class I devices. These criteria are listed in the text on page 350.
