3. A client does not understand why vision loss due to glaucoma is irreversible. What is the nurse's best explanation?

A. Once retinal detachment occurs, it does not return to its normal state
B. Once the tissue has necrosed from high-pressure, it does not regenerate
C. Glaucoma always leads to permanent blindness
D. Once bacterial infection has caused damage, the tissue does not regenerate

Correct answer: B

Rationale: The correct explanation for irreversible vision loss in glaucoma is that once the tissue has necrosed from high pressure, it does not regenerate. This necrosis occurs due to the damage caused by increased intraocular pressure, which leads to irreversible damage to the optic nerve and retinal tissue. Choices A, C, and D are incorrect because they do not directly address the specific mechanism of irreversible vision loss in glaucoma, which is necrosis due to high pressure.
