Answer to Question 1

ANS: B
The E chart is used when an individual is unable to read, as would be the case for a preschool-aged child. A Snellen chart and a reading test are too advanced for a preschooler's education level. A penlight is used to check light perception. Shine a penlight into the eye, and then turn it off. If the patient notes when the light is turned on or off, light perception is intact.

Answer to Question 2

ANS: A
Bronchovesicular breath sounds are created by air moving through large airways. Vesicular sounds are created by air moving through smaller airways. Bronchial sounds are created by air moving through the trachea close to the chest wall. Rhonchi are abnormal lung sounds that are loud, low-pitched, rumbling coarse sounds heard during inspiration or expiration that sometimes clear by coughing.
