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:
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.

Correct Answer is C
Explanation
This is the best action for the PN to take because it provides reality orientation and helps the client cope with the change in environment. The client may be experiencing acute confusion or delirium due to stress, medication, infection, or other factors. The PN should remind the client of the date, time, and place frequently and use other strategies such as calendars, clocks, and familiar objects to reduce confusion.
A. Documenting the client's loss of memory in the record is not enough and does not address the client's needs.
B. Notifying the family of the change in the client's condition is not a priority and may not be necessary if the confusion is temporary or reversible.
D. Encouraging the client to rest during the day is not appropriate and may worsen the confusion or disrupt the sleep-wake cycle.
Correct Answer is C
Explanation
The correct answer is choice c. Tell the UAP to continue because the unconscious client is positioned safely.
Choice A rationale:
Enrolling the UAP in a hospital education class on conducting safe client care is a proactive measure, but it is not an immediate action required in this scenario. The UAP is already performing the task correctly.
Choice B rationale:
Praising the UAP for doing the oral hygiene and encouraging family participation is positive reinforcement, but it does not address the immediate task at hand. The focus should be on ensuring the client’s safety during the procedure.
Choice C rationale:
Telling the UAP to continue because the unconscious client is positioned safely is the correct action. The side-lying position with an emesis basin under the chin is appropriate for an unconscious client as it helps prevent aspiration by allowing secretions to drain out of the mouth.
Choice D rationale:
Stopping the procedure and telling the UAP to place the client in a Fowler’s position is incorrect. The Fowler’s position is not suitable for oral hygiene in an unconscious client as it increases the risk of aspiration.
