Final answer:
The nurse should monitor for increased redness, swelling, and pain after enucleation, as it could indicate an infection or complications.
Step-by-step explanation:
After enucleation, which is the surgical removal of an eye, the nurse should closely monitor the client for any signs of infection or complications. One post-surgical observation that requires immediate attention is increased redness, swelling, and pain in the surgical site area. These symptoms could indicate an infection or other complications, and the nurse should notify the healthcare team immediately for further evaluation and treatment.
