a) Avoid activities that require bending over.
b) Contact the surgeon if eye scratchiness occurs.
c) Place an eye shield on the surgical eye at bedtime.
d) Episodes of sudden severe pain in the eye are expected.
e) Contact the surgeon if a decrease in visual acuity occurs.
f) Take acetaminophen (Tylenol) for minor eye discomfort.

8. Tonometry is performed on a client with a suspected diagnosis of glaucoma. The nurse looks at the test results documented in the client’s chart, knowing that which is the range for normal intraocular pressure?

a) 2 to 7 mm Hg
b) 10 to 21 mm Hg
c) 22 to 30 mm Hg
d) 31 to 35 mm Hg

9. The nurse is caring for a client following craniotomy for removal of an acoustic neuroma. Assessment of which cranial nerve would identify a complication specifically associated with this surgery?

a) Cranial nerve I, olfactory
b) Cranial nerve IV, trochlear
c) Cranial nerve III, oculomotor
d) Cranial nerve VII, facial nerve

10. The nurse notes that the health care provider has documented a diagnosis of presbycusis on a client’s chart. The nurse understands that which describes this condition?

a) Tinnitus that occurs with aging
b) Nystagmus that occurs with aging
c) A conductive hearing loss that occurs with aging
d) A sensorineural hearing loss that occurs with aging

NCLEX Question on Ophthalmology
Answers and Rationale

6) A
- Rationale: In this type of accident, the client is instructed to irrigate the eyes immediately with running water for at least 20 minutes, or until the emergency medical service personnel arrive. In the emergency department, the cleansing agent of choice is usually normal saline. Calling the HCP and going to the emergency department delays necessary intervention. Hydrogen peroxide is never placed in the eyes.

- Test-Taking Strategy: Note the strategic word immediate. Focus on the type of injury and eliminate options B and C because they delay necessary intervention. Next, eliminate option D because hydrogen peroxide is never placed in the eyes.

7) A, C, E, F
- Rationale: Following eye surgery, some scratchiness and mild eye discomfort may occur in the operative eye and usually is relieved by mild analgesics. If the eye pain becomes severe, the client should notify the surgeon because this may indicate hemorrhage, infection, or increased intraocular pressure. The nurse also would instruct the client to notify the surgeon of increased purulent drainage, increased redness, or any decrease in visual acuity. The client is instructed to place an eye shield over the operative eye at bedtime to protect the eye from injury during sleep and to avoid activities that increase intraocular pressure, such as bending over.

- NCLEX Question on Ophthalmology Test-Taking Strategy: Focus on the subject, postoperative care following eye surgery. Recalling that the eye needs to be protected and that increased intraocular pressure is a concern will assist in determining the home care measures to be included in the plan.

8) B
- Rationale: Tonometry is a method of measuring intraocular fluid pressure, using a calibrated instrument that indents or flattens the corneal apex. Pressures between 10 and 21 mm Hg are considered within the normal range.

- Test-Taking Strategy: Focus on the subject, normal intraocular pressure. Remember that normal intraocular pressure is between 10 and 21 mm Hg.

9) D
- Rationale: An acoustic neuroma (or vestibular schwannoma) is a unilateral benign tumor that occurs where the vestibulocochlear or acoustic nerve (cranial nerve VIII) enters the internal auditory canal. It is important that an early diagnosis be made because the tumor can compress the trigeminal and facial nerves and arteries within the internal auditory canal. Treatment for acoustic neuroma is surgical removal via a craniotomy. Assessment of the trigeminal and facial nerves is important. Extreme care is taken to preserve remaining hearing and preserve the function of the facial nerve. Acoustic neuromas rarely recur following surgical removal.

- Test-Taking Strategy: Focus on the subject, a complication following surgery. Think about the anatomical location of an acoustic neuroma and the nerves that the neuroma can compress to direct you to the correct option.

10) D
- Rationale: Presbycusis is a type of hearing loss that occurs with aging. Presbycusis is a gradual sensorineural loss caused by nerve degeneration in the inner ear or auditory nerve. Options A, B and C are incorrect.

- Test-Taking Strategy: Focusing on the subject, the description of presbycusis. Remember that presbycusis is a gradual sensorineural loss.
