Answer to Question 1

ANS: D
Excessive mucus in the airways causes crackles that are usually coarse (low pitched) and heard during inspiration and expiration. These crackles often clear when the patient coughs or when the upper airway is suctioned.

Answer to Question 2

ANS: A
It is useful to monitor the pitch and duration of wheezing. Improved expiratory flow is associat-ed with a decrease in the pitch and length of the wheezing. For example, if high-pitched wheez-ing is present during the entire expiratory time before treatment but becomes lower pitched and occurs only late in exhalation after therapy, the pitch and duration of the wheeze have dimin-ished. This suggests that the degree of airway obstruction has decreased.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
