Final answer:
The nurse should advise the client to avoid bending over to put on shoes, continue showering with caution, and keep the eye shield on while sleeping.
Step-by-step explanation:
Following the removal of a cataract, the nurse should provide the client with specific instructions for discharge. In this case, the nurse should tell the client to avoid bending over to put on his shoes to prevent strain or injury to the eye. The nurse should also instruct the client to continue showering as usual, but to be cautious and avoid getting water directly in the eye. Additionally, the nurse should advise the client to keep the eye shield on while sleeping, as it helps protect the eye during the healing process.
