Answer to Question 1

Correct Answer: 2
The red-free filter is used to examine the optic disc for hemorrhage. This filter shines a green beam into the eye and if hemorrhage is present, the disc will appear black. The color green is not an expected finding of fundoscopic examination of the eye. The color red is observed as the red reflex; light reflecting off the retina when a bright white light is shined through the pupil. This is a normal finding. Yellow is the color of a normal optic disc. This is elicited using the bright white light of the ophthalmoscope.

Answer to Question 2

Correct Answer: 1, 2

The otoscope can be used to inspect the nose, by inserting a wide speculum into the client's naris. The otoscope funnels light into the ear canal to allow the examiner to inspect the tympanic membrane (eardrum) as well as the ear canal itself. The ophthalmoscope is used to inspect the internal structure of the eye. The Doppler uses ultrasonic waves to detect pulses that are difficult to palpate. A Wood's lamp produces a black light that emits a yellow-green fluorescence on skin in the presence of a fungal infection.
