NURS 190 QUIZ 2: EYES, EARS, NOSE,
MOUTH, AND THROAT EXAM WITH
COMPLETE SOLUTIONS
Macula -ANSis responsible for central vision. It's yellow, pit like center called the fovea
central is, appears as a hyper-pigmented spot on the temporal aspect of the retina
pterygium -ANSthin tissue growing into the cornea from the conjunctiva, usually caused
from sun exposure
-UV induced temporary loss of vision
what equipment is used to assess objective data for the eye ? -ANS-visual acuity charts
-opaque card or eye cover
-penlight
-cotton tipped applicator
-ophthalmoscope
Cranial Nerve II: Optic -ANS-Function: sensory - carries impulse for vision
-Testing procedure: eye chart testing, visual field testing
Testing distance vision -ANSSnellen Chart
Snellen eye chart -ANSeye chart used by eye care professionals and others to measure
visual acuity.
-position patient exactly 20 ft away
-patient can be standing or seat
-chat must be eye level
-read lines from top to bottom
-read lines from left to right
-cover one eye at a time
-if patient wears glasses have them take the test with and without glasses
Findings of Snellen Chart -ANS-any findings other than 20/20 are considered abnormal.
ex: 20/40 means that the line the patient can read at 20 feet away can be read by a
person with normal vision at 40 feet away
Testing Peripheral Vision -ANS1. position patient (patient and examiner sit in front of
each other 2-3 ft away)
2. Explain to the patient that they will alternatively cover an eye and must look directly
into your open eye. A pen or penlight will be moved into the patients field of vision from
, four directions. The patient is to indicate by saying now or yes when the object is first
seen
extraocular movements -ANSeye movements controlled by several pairs of eye muscles
-stand about 2 ft in front of the patient
-hold pen 18 inches from patients face
-Letter H method:
-Wagon wheel method:
nystagmus -ANSInvoluntary rapid eye movements
-weakness in cranial nerve 3
Hirschberg test -ANSCorneal light reflex examination checking for ocular alignment
Ptosis -ANSeyelid drooping
-dysfunction of cranial nerve 3
PERLLA deals with which nerves ? -ANS3,4, and 6
consensual constriction -ANSThe simultaneous response of one pupil to the stimuli
applied to the other
Testing Eye Accommodation -ANS1. hold finger about 10cm or 4-5 inches from pt's
nose
2. ask them to alternate looking into distance and at your finger
3. observe the pupillary response in each eye
convergence of eyes -ANSMedial rotation of the eyes
-turning eye inward
-lack of convergence and failure of the pupils to construct indicates dysfunction of
cranial nerves 3,4, and 6
periorbital edema -ANSswelling of the tissues surrounding the eye or eyes; occurs with
crying, infection, trauma, and systemic problems including kidney failure, heart failure,
and allergy
exophthalmos -ANSabnormal protrusion of one or both eyeballs
-usually occurs secondary to Graves' disease (hyperthyroidism); causes also may
include infectious disease, certain forms of cancer and other disorders
Conjunctivitis -ANSinflammation of the conjunctiva
-infection of the conjunctiva usually because of bacteria or virus but which may result
from chemical exposure.
-commonly called pink eye
Cataract -ANSAn opacity of the lens of the eye; usually develops later in life
