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. The client had an allergic reaction to the ordered meperidine. B. The primary health care provider was notified because the client developed a rash after receiving an opioid analgesic. C. The client’s skin was warm and flushed, and a rash was noted on the chest and back. D. Thirty minutes after receiving meperidine, the temperature was 101°F (38.3°C).

Correct Answer is D

Explanation

Choice A rationale

Stating that the client had an allergic reaction to the ordered meperidine is not objective and does not provide specific details about the client’s condition.

Choice B rationale

Notifying the primary health care provider because the client developed a rash after receiving an opioid analgesic is important, but it does not include all the necessary details about the client’s condition.

Choice C rationale

Documenting that the client’s skin was warm and flushed, and a rash was noted on the chest and back is important, but it does not include the timing of the reaction or the client’s temperature.

Choice D rationale

Documenting that thirty minutes after receiving meperidine, the temperature was 101°F (38.3°C), the client’s skin was warm and flushed, and a rash was noted on the chest and back provides a complete and objective account of the client’s condition and the timing of the reaction.
