The client tells the nurse about being diagnosed with 'wet type' macular degeneration. Which finding should the nurse expect to observe when examining the client's eyes using an ophthalmoscope?
- A. Growth of abnormal blood vessels in the macula has occurred.
- B. Structures in the macula have atrophied.
- C. The lens of the eye has become cloudy.
- D. The edge of the cornea has a thin grayish arc.
Correct Answer: A
Rationale: The 'wet type' of macular degeneration results from the growth of abnormal blood vessels in the macula. The blood vessels often leak fluid and blood. Atrophy occurs in dry macular degeneration, cloudy lens indicates cataract, and corneal arcus is a normal finding in older clients.

The client with severe otitis media and mastoiditis is prescribed levofloxacin IV, 250 mg every 12 hours. The medication is diluted in 100 mL of NS. To deliver the antibiotic in 30 minutes, the nurse must infuse the solution at a rate of how many mL per hour?
- A. 200
Correct Answer: A
Rationale: The rate of IV infusion is calculated as follows: 100 mL over 30 minutes equals X mL over 60 minutes. Thus, 100/30 = X/60, so X = (100 × 60) / 30 = 200 mL/hr.
The client diagnosed with glaucoma is prescribed a miotic cholinergic medication. Which data indicate the medication has been effective?
- A. No redness or irritation of the eyes.
- B. A decrease in intraocular pressure.
- C. The pupil reacts briskly to light.
- D. The client denies any type of floaters.
Correct Answer: B
Rationale: Miotic cholinergics (e.g., pilocarpine) reduce intraocular pressure in glaucoma by increasing aqueous outflow. Redness, pupil reaction, and floaters are not primary indicators.
Which statement indicates to the nurse the client is experiencing some hearing loss?
- A. I clean my ears every day after I take a shower.
- B. I keep turning up the sound on my television.
- C. My ears hurt, especially when I yawn.
- D. I get dizzy when I get up from the chair.
Correct Answer: B
Rationale: Turning up the television volume suggests hearing loss. Ear cleaning is unrelated, ear pain suggests infection, and dizziness indicates vestibular issues.
The nurse is concerned that the Caucasian client experiencing a stroke may have impaired hearing. Which observations of the client's behavior prompted this concern? Select all that apply.

- B. Asks for more information about the therapy schedule
- C. Slow to respond verbally but answers questions appropriately
- D. Speaks in an excessively loud tone of voice

The client diagnosed with chronic otitis media is scheduled for a mastoidectomy. Which discharge teaching should the nurse discuss with the client?
- A. Instruct the client to blow the nose with the mouth closed.
- B. Explain the client will never be able to hear from the ear.
- C. Instill ophthalmic drops in both ears and then insert a cotton ball.
- D. Do not allow water to enter the ear for six (6) weeks.
Correct Answer: D
Rationale: Keeping the ear dry for six weeks prevents infection post-mastoidectomy. Blowing the nose closed increases pressure, hearing loss is not guaranteed, and ophthalmic drops are incorrect.
