When caring for a multisystem trauma patient, what should you expect to assess
after airway, breathing, circulation and disability: - ANSWER- Ocular injuries
commonly occur with head and facial injuries, so carefully evaluate patients with
these injuries for coexisting ocular injuries after evaluating and stabilizing airway,
breathing, circulation, and disability.
When caring for a multisystem trauma patient with a suspected ocular injury, what
step should you take after the primary survey?
A. Instill saline eye drops.
B. Forcibly open the eyelids, if needed, to assess ocular structures.
C. Remove the patient's contact lenses.
D. Apply a topical anesthetic. - ANSWER- if an unconscious or impaired patient,
look for and remove contact lenses as soon as possible.
In a multisystem trauma patient, what do you NOT want to do when it comes to
assessing the eyes? - ANSWER- Do not force open the eyelids because this action
may exacerbate any injury.
Do not instill eye drops before assessing for an ocular injury in a trauma patient.
Minimize severe pain associated with ocular trauma without topical anesthetics, by
- ANSWER- patch both eyes.
,Which eye structure controls the amount of light that enters the eye by dilating or
constricting the pupil?
A. Vitreous body B. Crystalline lens C. Iris D. Retina - ANSWER- The iris has a
round opening, the pupil, through which the light passes.
The iris controls the amount of light that enters the eye by dilating or constricting
the pupil.
Which eye structure controls the bending and refracting of light after light enters
the eye by dilating or constricting the pupil via the iris?
A. Vitreous body B. Crystalline lens C. Iris D. Retina - ANSWER- Then light
reaches the crystalline lens, which focuses light rays onto the retina by bending
(refracting) them.
which structure of the eye does most of the refraction and which structure does
fine-tunes focus - ANSWER- The cornea does most of the refraction, and the
crystalline lens fine-tunes the focus.
which structure in they eye is behind the lens and in front of the retina? -
ANSWER- Behind the lens and in front of the retina is the vitreous body, a
chamber that contains clear, gelatinous fluid called the vitreous humor.
which eye structure does light pass through before light reaches the retina? -
ANSWER- Light rays pass through the vitreous before reaching the retina.
which eye structure is responsible for the wide field of vision that most people
experience? - ANSWER- The retina lines the back two-thirds of the eye and is
responsible for the wide field of vision that most people experience.
,Cleaning the lid margins with mild shampoo is a treatment for which ocular
problem? - ANSWER- Blepharitis
Treatment of blepharitis includes removing the crusts and cleaning the lid margins
twice daily with a mild shampoo, applying warm compresses, and using artificial
tears.
Treatment of a chalazion (internal stye) includes - ANSWER- topical antibiotic
ointment and incision and drainage if vision is affected.
WHY should the nurse triage as most emergent A pt with Central retinal artery
occlusion? - ANSWER- Central retinal artery occlusion produces the sudden onset
of unilateral, painless vision loss and is a true ocular emergency.
Retinal circulation must be restored within 60 to 120 minutes (or less) to prevent
permanent vision loss.
To assess the external eye, the nurse should perform which activity?
A. Have the patient identify letters or objects on a chart or card.
B. Inspect and gently palpate the eyelids, lashes, and surrounding bony structures.
C. Have the patient follow the nurse's fingers with his or her eyes.
D. Visualize the external structures with a slit lamp. - ANSWER- An external eye
assessment consists of the inspection and gentle palpation of the eyelids, lashes,
and surrounding bony structures.
Visual acuity is assessed by having the patient identify letters or objects on a chart
or card.
Cardinal fields of gaze are assessed by having a patient follow the nurse's fingers
with his or her eyes.
, A slit-lamp microscope is used to help visualize the superficial structures and the
anterior chamber.
Retinal detachment requires consultation with an - ANSWER- Retinal detachment
requires consultation with an ophthalmologist to determine a definitive treatment,
such as laser repair or scleral buckling.
Herpes zoster ophthalmicus requires - ANSWER- Herpes zoster ophthalmicus
requires local wound care, administration of analgesics and antivirals, and possibly
topical steroids and antibiotics.
Hyphema requires consultation with an - ANSWER- Hyphema requires
consultation with an ophthalmologist.
In a patient with a globe rupture, which sign or symptom is expected?
A. Altered depth of the posterior chamber
B. Dilated pupil
C. Teardrop-shaped pupil
D. Decreased pain sensation - ANSWER- Signs and symptoms of a globe rupture
include hyphema, a teardrop-shaped pupil, altered depth of the anterior chamber,
altered light perception, vitreous hemorrhage (occasionally), and minimal to severe
pain.
Uveitis and iritis are inflammations of the uveal tract, which includes - ANSWER-
the iris, ciliary body, and choroid.
