D444 OA EXAM
1. A client with glaucoma is preparing for discharge. Which instruction should the
nurse prioritize?
A. Avoid bending at the waist, coughing, or straining
B. Use miotic eye drops only when vision is blurry
C. Resume weightlifting gradually over 2 weeks
D. Sleep with the head of bed flat to reduce eye strain
Correct Answer: A
Rationale: Glaucoma is characterized by increased intraocular pressure (IOP). Bending,
coughing, and straining significantly elevate IOP, which can worsen optic nerve damage
and lead to vision loss. Option B is incorrect because miotics like pilocarpine must be
used as prescribed, not PRN. Option C is incorrect because lifting increases IOP and is
contraindicated. Option D is incorrect because elevating the HOB actually helps reduce
IOP; lying flat increases venous pressure in the eye.
,2. A client returns from cataract surgery. Which discharge instruction is most
appropriate? (Select all that apply.)
A. Avoid bending at the waist
B. Lift objects no heavier than 10 pounds
C. Use stool softeners to prevent straining
D. Resume driving the day after surgery
E. Sleep on the operative side to promote drainage
Correct Answers: A, B, C
Rationale: Post-cataract surgery, the priority is preventing increased IOP. Bending at the
waist (A), lifting >10 lbs (B), and straining during bowel movements (C) all raise IOP and
threaten surgical outcomes. Option D is incorrect because vision is often blurry post-op,
and driving is unsafe. Option E is incorrect because sleeping on the operative side
increases pressure on the healing eye; clients should sleep on the non-operative side or
with an eye shield.
3. A client presents with intense eye pain, photophobia, and reports a sensation of
something in the eye after gardening. Which intervention should the nurse anticipate?
A. Prescribing topical anesthetic drops for home use
B. Applying an antibiotic ointment and possibly an eye patch
C. Administering corticosteroid drops immediately
D. Irrigating the eye with normal saline for 20 minutes
Correct Answer: B
Rationale: This presentation is consistent with a corneal abrasion. Treatment includes
antibiotic ointment to prevent infection and patching to promote healing. Option A is a
critical contraindication—topical anesthetics for home use mask worsening pain and can
cause "corneal melting" (permanent damage). Option C is generally contraindicated
initially because steroids suppress immune response and may cause fungal overgrowth
or corneal melting. Option D describes treatment for a chemical burn, not an abrasion.
,4. A client reports sudden onset of flashing lights, floaters, and a "curtain" over part of
their vision. What is the nurse's priority action?
A. Schedule a routine ophthalmology appointment within 48 hours
B. Instruct the client to rest the eyes and avoid bright lights
C. Recognize this as an ocular emergency and facilitate immediate treatment
D. Administer miotic eye drops to constrict the pupil
Correct Answer: C
Rationale: Flashing lights, floaters, and a "curtain" over vision are hallmark signs of
retinal detachment—an ocular emergency requiring immediate surgical intervention to
prevent permanent vision loss. Delaying care (A, B) risks irreversible damage. Option D is
incorrect; miotics are used for glaucoma, not retinal detachment.
5. A nurse is caring for a client with Ménière's disease. Which dietary modification
should be included in the teaching plan?
A. Increase sodium intake to maintain fluid balance
B. Follow a low-sodium diet
C. Eliminate all carbohydrates
D. Increase caffeine intake to improve alertness during vertigo episodes
Correct Answer: B
Rationale: Ménière's disease is an inner ear disorder characterized by vertigo, tinnitus,
and hearing loss caused by endolymphatic hydrops (fluid accumulation). A low-sodium
diet reduces fluid retention in the inner ear. Diuretics are also commonly prescribed.
Option A is opposite of correct management. Option C is unrelated. Option D is incorrect
because caffeine is a stimulant that can worsen tinnitus and vertigo.
6. A client with multiple sclerosis (MS) is admitted during a summer heat wave. Which
nursing intervention is the priority?
A. Encourage the client to take hot baths to relax muscles
B. Keep the room cool and avoid overheating
,C. Administer high-dose corticosteroids prophylactically
D. Increase fluid intake to prevent dehydration only
Correct Answer: B
Rationale: MS is an autoimmune demyelinating disease where heat stress worsens
symptoms (Uhthoff's phenomenon). Keeping the environment cool prevents flare-ups.
Option A is dangerous—hot baths exacerbate symptoms. Option C is not a prophylactic
measure; steroids treat acute exacerbations, not prevent heat-related symptoms. Option
D is partially correct but incomplete; cooling the environment is the priority.
7. A nurse is assessing a client with myasthenia gravis. Which finding is most consistent
with the disease?
A. Muscle weakness that improves with activity and worsens with rest
B. Ptosis and dysphagia that worsen as the day progresses
C. Resting tremor and rigidity in the extremities
D. Bilateral hearing loss and tinnitus
Correct Answer: B
Rationale: Myasthenia gravis is characterized by muscle weakness that worsens with
activity and improves with rest, with ptosis (drooping eyelids) and dysphagia being
hallmark signs. Option A reverses the correct pattern. Option C describes Parkinson's
disease. Option D describes Ménière's disease.
8. A client with myasthenia gravis is scheduled for meals. Which medication timing is
most appropriate?
A. Give pyridostigmine immediately after meals
B. Give pyridostigmine 30 minutes before meals
C. Hold pyridostigmine if the client is NPO
D. Administer pyridostigmine at bedtime only
Correct Answer: B
Rationale: Pyridostigmine (an acetylcholinesterase inhibitor) should be given 30–60
, D444 OA Study Guide & Clinical Prioritization
1. Glaucoma priority: Avoid anything that increases intraocular pressure; no bending,
coughing, or straining.
2. Cataracts post-op priority: Avoid bending, lifting, or straining to prevent increased eye
pressure.
3. Corneal Abrasions: Scratches on the cornea causing intense pain and photophobia;
treated with antibiotic ointment and sometimes patching.
4. Retinal Detachment: Separation of the retina from the epithelium; characterized by
flashing lights, floaters, and a "curtain" over the vision; an ocular emergency.
5. Meniere's Disease: Inner ear disorder characterized by vertigo, tinnitus, and hearing
loss; managed with low-sodium diet and diuretics.
6. Vertigo: Sensation of spinning or dizziness; nursing priority is safety and fall prevention.
7. Multiple sclerosis key features: Autoimmune demyelination causing fatigue, weakness,
vision problems, and heat sensitivity.
8. Myasthenia gravis key features: Muscle weakness that worsens with activity, improves
with rest, with ptosis and dysphagia.
9. Myasthenia gravis priority: Maintain airway and give pyridostigmine before meals.
10. Parkinson's Disease key features: Resting tremor, rigidity, slow movement, and shuffling
gait.
11. Parkinson's priority: Give levodopa on time and prevent falls.
12. Seizure Disorders Priority: Protect airway, turn patient on side, do not restrain.
13. Pulmonary embolism priority: Oxygen first, then anticoagulants.
14. Melanoma: Most aggressive skin cancer; identified by the ABCDE rule (Asymmetry,
Border, Color, Diameter, Evolving).
15. Herpes Zoster (Shingles): Reactivation of varicella-virus; presents as painful vesicles
along a dermatome; requires airborne/contact precautions if disseminated.
