Answer to Question 1

ANS: A
When respiratory disease reduces arterial oxygen content, cyanosis (a bluish discoloration of the tissues) may be detected, especially around the lips and in the oral mucosa of the mouth (central cyanosis).

Answer to Question 2

ANS: A
These devices do not require the health care provider to listen for the Korotkoff sounds and eliminate variances in recorded blood pressures based on human perception. They are considered to be very accurate and simply require the clinician to apply the blood pressure cuff correctly and press the start button. Subsequently, the device takes over and inflates and deflates the cuff au-tomatically. The blood pressure and pulse rate are then displayed on a digital screen.
