Nokea
A client use a corneal ulcer. What information provided by the client most indicates a potential barrier to home care?
- A. Chronic use of sleeping pills
- B. Impaired near vision
- C. Slightly shaking hands
- D. Use of contact lenses
Correct Answer: A
Rationale: Antibiotic eyedrops are often needed every hour for the first 24 hours for corneal ulceration. The client who uses sleeping pills may not wake up each hour or may awaken unable to perform this task. Impaired near vision and shaking hands can both make administration of eyedrops more difficult but are not the most likely barriers. Contact lenses should be discarded.

- A. Family history of visual problems
- B. Impact on daily activities
- C. History of falls
- D. Access to transportation
Correct Answer: B
Rationale: Cataracts can significantly impair vision, affecting the client's ability to perform daily activities safely.

A client is taking timolol (Timoptic) eyedrops. The nurse assesses the clients pulse at 50 beats/min. What action by the nurse is best?
- A. Administer the eyedrops as ordered.
- B. Assess the client for excessive salivation.
- C. Assess the client for shortness of breath.
- D. Hold the eyedrops and notify the provider.
Correct Answer: D
Rationale: Timolol is a beta blocker that can slow the heart rate. A pulse of 50 beats/min warrants holding the eyedrops and notifying the provider. Excessive salivation and shortness of breath are not typically related to timolol.
A client asks why blindness occurred from glaucoma. What explanation by the nurse is best?
- A. Because eye pressure was too high, the tissue died.
- B. Glaucoma always leads to permanent blindness.
- C. The traumatic damage to your eye was too great.
- D. The infection occurs so quickly, it can be treated.
Correct Answer: A
Rationale: Glaucoma is caused when the intraocular pressure becomes too high and stays high long enough to cause tissue ischemia and death. At that point, vision loss is permanent. Glaucoma does not always cause blindness, trauma is not the most common cause, and glaucoma is not an infection.
A client is seen in the ophthalmology clinic with bacterial conjunctivitis. Which statements by the client indicate correct understanding? (Select all that apply.)
- A. I won't wipe my eyes with the same cloth and share my towel.

- C. I have been prescribed antibiotics for my infection.
- D. I won't touch the tip of the eyedrop bottle to my eye.
- E. When the infection is gone, I can wear my contacts again.
Correct Answer: C,D
Rationale: Bacterial conjunctivitis is very contagious, and re-infection or cross-contamination must be avoided. Not touching the eyedrop bottle tip to the eye and using prescribed antibiotics are correct actions. Sharing towels, improper irrigation, or premature contact lens use can worsen or spread the infection.

- A. Administer a tetanus booster shot.
- B. Ensure a patent airway.
- C. Prepare to irrigate the client's eye.
- D. Turn the client on the unaffected side.

Rationale: Airway always comes first in emergency care. After ensuring a patent airway and providing cervical spine precautions, other care such as administering a tetanus booster shot may be considered. The eye should not be irrigated with a foreign body present.
