A. The patient's O2 delivery may become compromised.
B. The patient may develop intrapulmonary shunting.
C. The patient's respiratory drive may become compromised.

?ANS: A
A. Correct response: Sedation must be considered for patients who become agitated.
Patients who are agitated have excessive O2 requirements, which may be detrimental in the setting of respiratory failure and shock (hypotension). In these patients, sedation may be important for favorable O2 delivery/O2 consumption balance (DO2/ O2), and improved cardiopulmonary stability. ?B. Incorrect response: See explanation A.
