Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: The confusion assessment method (CAM-ICU) is used to recognize the presence of delirium in ICU patients. Ordinarily the diagnosis of delirium is made by a psychiatrist. However, because of the difficulty in communicating with ICU patients, the CAM has been modified to apply to this patient population. The CAM-ICU comprises four features: (1) the acute onset of mental status changes, (2) inattention, (3) disorganized thinking, and (4) altered level of consciousness.
D. Incorrect response: See explanation C.

Answer to Question 2

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.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.
