Correct Answer is C

Explanation

Choice A rationale

Applying a non-pressure patch to the affected eye can help protect the eye from further irritation or injury. However, it does not address the underlying issue of purulent drainage, which could indicate an infection that requires immediate medical attention.

Choice B rationale

Cleaning the eye from inner to outer canthus is a standard practice to prevent the spread of infection. However, in this case, the presence of purulent drainage suggests a possible infection that needs to be evaluated by a surgeon.

Choice C rationale

Notifying the surgeon is the priority action because purulent drainage from the eye can indicate a serious infection or complication following surgery. Immediate medical evaluation and intervention are necessary to prevent further complications and ensure proper treatment.

Choice D rationale

Instilling an antibiotic solution in both eyes may be part of the treatment plan for an infection. However, the nurse should first notify the surgeon to get appropriate orders and ensure that the correct antibiotic and treatment plan are followed.

A. Speak loudly and into the client’s good ear. B. Use sign language when communicating with the client. C. Sit by the client’s side and speak very slowly. D. Speak directly to the client in a normal, clear voice.

Correct Answer is D

Explanation

Choice A rationale

Speaking loudly and into the client’s good ear is not recommended. Loud speech can be distorted and uncomfortable for individuals with presbycusis.

Choice B rationale

Using sign language is not necessary unless the client is proficient in it. Most clients with presbycusis benefit more from clear verbal communication.

Choice C rationale

Sitting by the client’s side and speaking very slowly is not as effective as speaking directly to the client in a normal, clear voice.

Choice D rationale

Speaking directly to the client in a normal, clear voice is recommended. This ensures that the client can read lips and understand the conversation better.
