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?

This is the best initial intervention for the PN to implement because it promotes comfort, relaxation, and circulation for the client. A back rub can also reduce anxiety and muscle tension, which can interfere with sleep. The PN should use non-pharmacological methods to facilitate sleep before resorting to medication.

A. Offering the client a prescribed sleep medication is not the best initial intervention because it may have side effects or interactions with other drugs. The PN should assess the client's need for medication and use it as a last resort.

C. Administering an as-needed (PRN) prescription for pain is not the best initial intervention because it may not address the cause of the client's difficulty in sleeping. The PN should assess the client's pain level and use other methods to relieve pain before giving medication.

D. Providing a cup of hot chocolate at bedtime is not the best initial intervention because it may contain caffeine, which can stimulate the central nervous system and keep the client awake. The PN should avoid giving caffeinated beverages to the client before bedtime.

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:

A. 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.

B. 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.

C. 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.
