Correct Answer is D

Explanation

Choice A rationale

Itching is a common symptom after cataract surgery, and the client should be reminded not to rub or place pressure on the eyes. This comment does not indicate a serious complication.

Choice B rationale

Sensitivity to bright light is also common after cataract surgery. The client can be advised to wear sunglasses to reduce discomfort. This comment does not indicate a serious complication.

Choice C rationale

Fear of falling is a valid concern, especially if the client has impaired vision or depth perception due to the eye patch. However, this comment does not indicate a serious complication that needs immediate reporting.

Choice D rationale

Severe pain in the eye after cataract surgery can indicate a complication such as increased intraocular pressure, infection, or hemorrhage. This comment should be reported to the provider immediately for further evaluation and intervention.

A. I need to drink room temperature beverages. B. I can take a prescribed analgesic to help manage the pain. C. I need to be careful not to spread this to my family. D. The chemotherapy affected my immune system.

Correct Answer is C

Explanation

Drinking room temperature beverages can help minimize irritation in the mouth and throat, which is beneficial for clients with stomatitis. Cold or hot beverages can exacerbate the condition by causing discomfort and pain.

Choice B rationale

Taking a prescribed analgesic can help manage the pain associated with stomatitis. Pain management is crucial for maintaining the client’s comfort and ability to eat and drink.

Choice C rationale

Stomatitis is not contagious and cannot be spread to family members. This statement indicates a need for further teaching as it reflects a misunderstanding of the condition.

Choice D rationale

Chemotherapy can affect the immune system, making the client more susceptible to infections and conditions like stomatitis. This statement is accurate and does not indicate a need for further teaching.
