B
Feedback:
The nurse should look for cloudiness of the lens in clients suspected to have cataracts. Blepharitis, not cataracts, is usually characterized by red lid margins. Drooping of the eyelid is seen in clients with ptosis and not cataracts. Cataracts are characterized by narrowing of the pupils, not dilation of the pupils.
