The practical nurse (PN) is reviewing a client's recent ophthalmic screening test results. Findings of optic neuropathy, loss of peripheral vision, and increased intraocular pressure are consistent with which medical condition?
Glaucoma
Macular edema.
Cataract
Diabetic retinopathy
The Correct Answer is A
Glaucoma is a group of eye diseases that damage the optic nerve and cause vision loss. It is often associated with increased intraocular pressure, which can compress the nerve fibers and reduce blood flow to the retina. The most common type of glaucoma, open-angle glaucoma, causes gradual loss of peripheral vision.
The other options are not correct because:
- Macular edema is a condition that causes swelling and fluid accumulation in the macula, the central part of the retina that is responsible for sharp and detailed vision. It can cause blurred or distorted vision, but it does not affect the optic nerve or the peripheral vision.
- Cataract is a condition that causes clouding of the lens, which is the transparent structure that focuses light onto the retina. It can cause blurred, dim, or yellowed vision, but it does not affect the optic nerve or the intraocular pressure.
- Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina and causes bleeding, leakage, or scarring. It can cause blurred, fluctuating, or darkened vision, but it does not affect the optic nerve or the intraocular pressure.

Explanation
This is the best action for the PN to use in assisting this client to deal with his pain because it provides a non-pharmacological method of pain relief that can enhance the effect of the opioid analgesic.

A. Dimming the lights in the room and closing the door may not be enough to help the client deal with his pain and may not address his psychological or emotional needs.
C. Turning the television on to the client's favorite show may not be effective in helping the client deal with his pain and may be distracting or irritating for him.
D. Obtaining a prescription for a higher dose of pain medication may not be necessary or appropriate for this client and may increase the risk of side effects or dependence. The PN should assess the client's pain level and response to the current dose before requesting a change in medication.
