Nokea
The nurse is caring for the client with macular degeneration. Which illustration should the nurse associate with the field disturbance seen by the client?
- A. Limited peripheral vision is shown in illustration 1.
- B. Distorted central vision as seen in illustration 2.
- C. Illustration 3 shows a normal visual field.
- D. Illustration 4 shows a blurred visual field.
Correct Answer: B
Rationale: Distorted central vision as seen in illustration 2 is characteristic of macular degeneration. The macula is the area of the fundus responsible for central vision. When the cells in the macula have been damaged, central vision is impaired. Illustration 1 shows glaucoma, 3 shows normal vision, and 4 shows blurred vision from various conditions.

The client comes to the emergency department after splashing chemicals into the eyes. Which intervention should the nurse implement first?
- A. Have the client move the eyes in all directions.
- B. Administer a broad-spectrum antibiotic.
- C. Irrigate the eyes with normal saline solution.
- D. Determine when the client had a tetanus shot.

Which assessment technique should the nurse use to assess the client's optic nerve?
- A. Have the client identify different smells.
- B. Have the client discriminate between sugar and salt.
- C. Have the client read the Snellen chart.
- D. Have the client say 'ah' to assess the rise of the uvula.
Correct Answer: C
Rationale: The optic nerve (cranial nerve II) is assessed by visual acuity tests like the Snellen chart. Smells (olfactory), taste (facial/glossopharyngeal), and uvula movement (vagus) involve other nerves.
The nurse is concerned that the client in a long-term care facility is experiencing retinal detachment. Which intervention should the nurse implement first?
- A. Flush the eye thoroughly with saline solution and apply a pressure bandage.
- B. Apply an eye shield to the affected eye and give a prescribed oral analgesic.
- C. Notify the HCP; prepare for transport to a facility for ophthalmological care.
- D. Patch both eyes and place the client in a prone position until blurring stops.
Correct Answer: C
Rationale: The nurse should contact the HCP and secure an ophthalmological evaluation promptly. Flushing the eye and applying a pressure bandage may cause further injury and delay treatment. Applying an eye shield and analgesic or patching both eyes delays securing treatment.
The client is two (2) hours postoperative right-ear mastoidectomy. Which assessment data should be reported to the health-care provider?
- A. Complaints of aural fullness.
- B. Hearing loss in the affected ear.

Correct Answer: D
Rationale: Facial drooping suggests cranial nerve VII injury, a serious complication post-mastoidectomy, requiring immediate reporting. Fullness and hearing loss are expected, and no vertigo is normal.
