Question: Which symptom is most commonly associated with cataracts?
A. Sudden eye pain
B. Halos around lights
C. Gradual loss of peripheral vision
D. Floaters in the visual field
Answer: B
Rationale: Cataracts cause clouding of the lens, leading to blurred vision and halos around lights.

D. Teach lip-reading skills
Answer: C
Rationale: Antibiotics treat the infection that can lead to conductive hearing loss.
Question: What is the primary treatment goal for conductive hearing loss?
A. Improve sound transmission to the inner ear.
B. Strengthen the auditory nerve.
C. Remove damaged cochlear hair cells.
D. Block excess sound vibrations
Answer: A
Rationale: Conductive hearing loss treatment focuses on restoring sound conduction.
Question: What is a priority nursing intervention for a patient with macular degeneration?
A. Encourage sunglasses outdoors
B. Educate about using central vision aids
C. Emphasize a diet low in cholesterol
D. Teach methods to reduce intraocular pressure
Answer: B
Rationale: Central vision aids, like magnifiers, are essential for patients with macular degeneration.
Question: A patient with macular degeneration complains of worsening central vision. Which action is most appropriate?
A. Advise the patient to wear corrective lenses.
B. Refer the patient for low-vision aids.
C. Schedule the patient for cataract surgery.
D. Perform an otoscopic exam.
Answer: B
Rationale: Low-vision aids help patients manage the loss of central vision caused by macular degeneration
Question: A patient with glaucoma reports blurry vision and eye pain. What should the nurse do first?
A. Check intraocular pressure
B. Administer eye drops as prescribed
C. Notify the healthcare provider immediately
D. Educate about avoiding bright lights
Answer: A
Rationale: Elevated intraocular pressure needs immediate assessment.
Question: Which statement indicates effective teaching for a patient with glaucoma?
A. “Glaucoma can be cured with surgery.”
B. “I should take my eye drops even if my vision improves.”
C. “I should stop taking my eye drops if I experience eye redness.”
D. “Glaucoma only affects one eye at a time.”
Answer: B
Rationale: Glaucoma management requires consistent use of prescribed medications to control intraocular pressure.
Question: A diabetic patient complains of tingling and numbness in their feet. What is the priority intervention?
A. Advise wearing open-toed shoes.
B. Inspect feet for injuries daily.
C. Apply heating pads to improve circulation.
D. Reduce physical activity to avoid pain.
Answer: B
Rationale: Daily foot inspection prevents unnoticed injuries that can lead to serious complications.
Question: What is a common treatment for managing peripheral neuropathy?
A. Steroid therapy
B. Anticonvulsant medications
C. Intravenous antibiotics
D. High-protein diet
Answer: B
Rationale: Anticonvulsants like gabapentin help relieve nerve pain associated with peripheral neuropathy.
Question: What is the most common cause of sensorineural hearing loss in adults?
A. Aging
B. Ear infections
C. Wax buildup
D. Trauma to the outer ear
Answer: A
Rationale: Presbycusis, or age-related hearing loss, is the most common type of sensorineural hearing loss.
Question: What is the primary intervention for severe sensorineural hearing loss in children?
A. Cochlear implant placement
B. Earwax removal
C. Use of antiviral medications
D. Tympanoplasty surgery
Answer: A
Rationale: Cochlear implants bypass damaged hair cells and directly stimulate the auditory nerve.
Question: What is the nurse’s priority action for a patient with a penetrating eye injury?
A. Flush the eye with sterile saline.
B. Cover both eyes to prevent movement.
C. Remove the foreign object immediately.
D. Apply pressure to stop bleeding.
Answer: B
Rationale: Covering both eyes prevents further movement that could worsen the injury.
Question: Which symptom should the nurse expect in a patient with a corneal abrasion?
A. Gradual loss of central vision
B. Severe eye pain and tearing
C. Cloudy vision with halos
D. Complete loss of vision
Answer: B
Rationale: A corneal abrasion typically causes severe pain, tearing, and sensitivity to light.
Question: A patient with cataracts states, “I’m afraid I will lose all my vision.” How should the nurse respond?
A. “Cataracts can cause complete blindness if untreated.”
B. “The surgery has a high success rate and often restores vision.”
C. “You should start preparing for vision loss now.”
D. “Cataracts only cause temporary vision changes.”
Answer: B
Rationale: Cataract surgery is a highly effective treatment that restores vision for most patients.
Question: Which of the following would the nurse include in teaching for a patient with recurrent cerumen impaction?
A. “Use a cotton swab to clean your ears regularly.”
B. “Avoid using ear drops to prevent wax buildup.”
C. “Schedule regular ear irrigation with your healthcare provider.”
D. “Only clean your ears if they feel full or blocked.”
Answer: C
Rationale: Regular ear irrigation by a professional can prevent recurrent wax buildup and related hearing issues.
Question: What is an expected finding in the assessment of a patient with cataracts?
A. Cloudy appearance of the eye lens
B. Red and inflamed sclera
C. Severe pain in the affected eye
D. Loss of peripheral vision
Answer: A
Rationale: Cataracts cause a cloudy or opaque lens, affecting the patient’s vision.
Question: During an assessment, the nurse suspects conductive hearing loss. Which finding supports this suspicion?
A. Tinnitus in both ears
B. Difficulty hearing in noisy environments
C. Bone conduction better than air conduction on the Rinne test
D. Difficulty understanding high-frequency sounds
Answer: C
Rationale: Bone conduction exceeding air conduction suggests conductive hearing loss.
Question: Which dietary recommendation is appropriate for a patient with macular degeneration?
A. “Avoid foods high in protein.”
B. “Increase intake of leafy green vegetables and fish.”
C. “Focus on foods low in fiber and fat.”
D. “Reduce consumption of foods containing vitamin C.”
Answer: B
Rationale: Leafy greens and fish are rich in antioxidants and omega-3s, which can slow the progression of macular degeneration.
Question: Which statement by the patient indicates understanding of their macular degeneration diagnosis?
A. “I will likely lose my peripheral vision.”
B. “I need to prepare for complete blindness.”
C. “I should use bright lighting to help me see better.”
D. “This condition is caused by an infection in my eye.
Answer: C

Question: Which type of glaucoma is considered a medical emergency?
A. Primary open-angle glaucoma
B. Secondary glaucoma
C. Acute angle-closure glaucoma

Question: A patient with glaucoma is prescribed timolol eye drops. What is the primary purpose of this medication?
A. To decrease eye inflammation
B. To prevent cataract formation
C. To lower intraocular pressure
D. To dilate the pupil
Answer: C
Rationale: Timolol is a beta-blocker used to reduce intraocular pressure in glaucoma patients.
