NUR 2180 / NUR2180: Physical Assessment
Ears, Eyes, Nose, Mouth, and Throat
Study Guide
After completing the reading assignment, write or draw answers in spaces provided and answer
the multiple choice questions.
1. Name the 6 sets of extraocular muscles and the cranial nerve that innervates each one of them.
Cranial nerve three: superior, oblique, superior rectus, inferior oblique, inferior rectus
Cranial nerve four: medial rectus
Cranial nerve six: lateral rectus
Superior oblique - CN IV (trochlear)
Medial Rectus- CN III (oculomoto)
Inferior Rectus- CN VI (Abducens)
Inferior Oblique- CN III (oculomotor)
Lateral Rectus- CN III (oculomotor)
Superior Rectus- CN III (oculomotor)
2. Explain what 20/150 means in terms of visual acuity.
The person is standing about 20 feet away from the eye chart and they would see an average of
150 feet from the eye chart
3. To test for accommodation, the person focuses on a distant object and then shifts the gaze to a
near object about 6 inches away. At near distance, you would expect the pupils to
constrict (dilate/constrict) and the axes of the eyes to
converge .
4. Identify common age-related changes in the eye.
-Decrease tear prod
-Infiltration of degenerative lipid material shows around limbus
-decreased pupil size
-lens loses elasticity, becoming glasslike & hard
, 5. What does it indicate when the examiner records “positive consensual light reflex”?
a. Convergence of the axes of the eyeballs
b. Simultaneous constriction of the other pupil when one eye is exposed to bright light
c. Reflex direction of the eye toward in object attracting a person’s attention
d. Adaptation of the eye for near vision
6. How is visual acuity assessed?
a. Snellen eye chart
b. Ophthalmoscope
c. Hirschberg test
d. Confrontation test
7. What is conjunctivitis associated with?
a. Absent red reflex
b. Reddened conjunctiva
c. Impairment of vision
d. Fever
8. What is the cause of the red reflex?
a. Petechial hemorrhage sin the sclera
b. Diabetic retinopathy
c. Light reflecting from the retina
d. Blood in the vitreous
9. Documentation of an eye examination can include the term PERRLA. What does it mean”
a. P pupils
b. E equal
c. R round
d. R react
e. L light
f. A accommodation
10. What is one cause of visual impairment in aging adults?
a. Strabismus
b. Glaucoma
c. Amblyopia
d. Retinoblastoma

11. Describe the whispered voice test of hearing acuity.
Examiner stands behind patient and tests both ears one at a time
