Final answer:
The correct statement that should be reinforced by the nurse is the one about taking extra fiber and drinking water to avoid constipation, which can help manage glaucoma by preventing increases in intraocular pressure.
Step-by-step explanation:
A nurse is speaking to a group of retired people about glaucoma. The comment by one of the retirees that is correct and should be reinforced by the nurse is,
"I take extra fiber and drink lots of water to avoid getting constipated."
Constipation can increase intraocular pressure, which can worsen glaucoma. A high-fiber diet and adequate hydration can help manage constipation, thereby potentially contributing to the management of intraocular pressure in glaucoma patients. It's important for individuals with this condition to maintain a healthy lifestyle and follow any medical advice or treatments recommended by their healthcare providers to manage their glaucoma effectively.
