CEN OCULAR QUESTIONS WITH COMPLETESOLUTIONS
A blowout fracture is characterized by Correct Answers
subconjunctival hemorrhage,
enophthalmos (sunken eye),
limited upward gaze,
periorbital ecchymosis,
periorbital edema, and diplopia.
The fracture itself does not cause pupil constriction.
A common mechanism of a globe rupture is Correct Answers
penetrating trauma from an object, such as a stick, pencil,
scissors, or knife. Globe rupture also may result from blunt
trauma that abruptly increases intraocular pressure.
A funduscopic examination is used to evaluate which structure?
Correct Answers Posterior chamber
A funduscopic examination allows visualization of the posterior
chamber of the eye.
a patient with a corneal abrasion, REQUIRES WHICH
discharge instructionS if appropriate? Correct Answers Avoid
wearing contact lenses until follow-up is completed.
Patching is no longer recommended.
A corneal abrasion does not need irrigation
A patient with a corneal infection may develop a Correct
Answers hypopyon (collection of pus due to white blood cells
in the anterior chamber of the eye).
,A patient with an orbital blowout fracture is likely to have which
finding?
A. Pupil constriction B. Exophthalmos C. Limited downward
gaze Correct Answers Subconjunctival hemorrhage
A patient with an orbital blowout fracture is likely to have which
finding? Correct Answers Subconjunctival hemorrhage
An orbital blowout fracture occurs when an orbital floor fracture
increases the intraocular pressure, causing the orbital contents to
herniate into the maxillary or ethmoid sinuses and trap the
inferior rectus muscle.
A patient with which disorder would benefit most from an eye
shield?
A. Hyphema B. Corneal abrasion C. Eye infection D. Globe
rupture Correct Answers An eye shield (patch) minimizes
ocular stimulation by reducing movement and limiting light
exposure, which is indicated for a patient with a globe rupture.
A patient with hyphema (a collection of blood in the anterior
chamber) would not benefit from minimizing ocular stimulation.
Patching a simple corneal abrasion does not shorten healing time
or decrease pain, so it is no longer routinely recommended. An
eye infection contraindicates patching.
A patient with which intraocular pressure measurement requires
further treatment?
A. 5 mm Hg
,B. 10 mm Hg
C. 20 mm Hg
D. 30 mm Hg Correct Answers Intraocular pressure normally
ranges from 10 to 20 mm Hg. Consultation with an
ophthalmologist is recommended when the pressure exceeds 20
mm Hg, although treatment may not be indicated until the
pressure reaches 30 mm Hg or higher.
A PT WITH Orbital cellulitis WHEREIN A NURSE NEEDS
TO EVALUATE THEIR EXTRAOCULAR MOVEMENTS IS
TEST HOW? Correct Answers in Orbital cellulitis, the nurse
evaluates extraocular movements by testing the six cardinal
fields of gaze.
A severe chemical burn may require how many hours of
irrigation: and how often do you check pH Correct Answers 2
to 4 hours of irrigation
Measure the pH periodically during and after the initial
irrigation.
Allergic conjunctivitis typically results from Correct Answers
An allergen that causes the eyes to tear and the lids to itch.
Although vomiting does not cause globe rupture, it frequently
results from penetrating trauma from an object and increases
intraocular pressure and the risk of Correct Answers expulsion
of intraocular contents.
An external eye examination allows the nurse to assess Correct
Answers the cornea, conjunctiva, and iris
, An orbital blowout fracture occurs when an orbital floor fracture
increases the Correct Answers intraocular pressure, causing the
orbital contents to herniate into the maxillary or ethmoid sinuses
and trap the inferior rectus muscle.
appropriate for treatment of a hyphema Correct Answers
Application of an eye shield and elevation of the head of the bed
bacterial and viral conjunctivitis discharge instructions for these
infections ARE DIFFERENT FROM WHICH conjunctivitis
Correct Answers Allergic conjunctivitis does not require these
measures. Topical antibiotic application is typically prescribed
for a patient with bacterial conjunctivitis but not allergic
conjunctivitis.
bacterial and viral conjunctivitis discharge instructions for these
infections include Correct Answers thorough hand washing,
discarding eye makeup, and avoiding cross-contamination
through towels and pillows.
Because bacterial and viral conjunctivitis are highly contagious,
because of the risk of Pseudomonas infection, DO NOT APPLY
? TO A PATIENT WITH HYPOPYN Correct Answers Do not
patch the eye because of the risk of Pseudomonas infection,
which is a particular concern with contact lens wearers.
Irrigation with copious fluids is an intervention for a chemical
burn, not a hypopyon.
bleeding between the conjunctiva and sclera Correct Answers
A subconjunctival hemorrhage is a common benign condition. A
