Correct Answer is D

Explanation

A. Ask the client to identify scented aromas: This assesses cranial nerve I (olfactory), not cranial nerve II.
B. Listen to the client's speech: This assesses cranial nerve IX and X (glossopharyngeal and vagus), not cranial nerve II.
C. Ask the client to clench his teeth: This assesses cranial nerve V (trigeminal), not cranial nerve II.

A. The cone of light at 7 o'clock in the right ear and 5 o'clock in the left ear with a pink and moist tympanic membrane. B. The cone of light at 7 o'clock in the right ear and 5 o'clock in the left ear with a pearly gray tympanic membrane. C. The cone of light at 5 o'clock in the right ear and 7 o'clock in the left ear with a pink and moist tympanic membrane. D. The cone of light at 5 o'clock in the right ear and 7 o'clock in the left ear with a pearly gray tympanic membrane.

Correct Answer is B

Explanation

A. The cone of light at 7 o'clock in the right ear and 5 o'clock in the left ear with a pink and moist tympanic membrane is not a typical finding, as the tympanic membrane should be pearly gray.
B. The cone of light at 7 o'clock in the right ear and 5 o'clock in the left ear with a pearly gray tympanic membrane is the expected finding for a normal ear exam, showing the healthy tympanic membrane and the proper positioning of the cone of light.
C. The cone of light at 5 o'clock in the right ear and 7 o'clock in the left ear with a pink and moist tympanic membrane is incorrect, as the tympanic membrane should be pearly gray, not pink and moist.
D. The cone of light at 5 o'clock in the right ear and 7 o'clock in the left ear with a pearly gray tympanic membrane is an incorrect positioning of the cone of light (should be at 7 o'clock for the right ear and 5 o'clock for the left).
