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 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:

1. 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.
2. 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.
3. 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.
4. 

The correct answer isChoice B.

Choice B rationale:

The practical nurse (PN) should instruct the unlicensed assistive personnel (UAP) to keep the client's skin clean and dry. Proper skin care is essential for a client with urinary and fecal incontinence to prevent the development of pressure ulcers. Keeping the skin clean and dry helps reduce moisture-related skin breakdown.

Choice A rationale:

Encouraging the client to rest quietly in bed is not directly related to preventing pressure ulcers. While adequate rest is essential for overall health, it does not specifically address the risk of pressure ulcers in an incontinent client.

Choice C rationale:

Obtaining supplies for contact precautions is unrelated to the client's risk of developing a sacral pressure ulcer. Contact precautions are used to prevent the spread of infectious diseases and do not address skin integrity.

Choice D rationale:

Documenting any changes in skin integrity is important, but it is the responsibility of the healthcare team, including the PN. However, this response does not provide proactive measures to prevent the pressure ulcer from occurring in the first place, which is the primary concern in this situation.
