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.

Correct Answer is B
Explanation
The correct answer is **b. Oral feeding of a two-year-old child after application of a hip spica cast.**
Choice A rationale:
Participation in staff rounds to record notes regarding client goals is not an appropriate task to delegate to a UAP. This task requires clinical assessment, judgment, and documentation skills that are within the scope of practice of a licensed practical nurse (PN), but not a UAP.
Choice B rationale:
Oral feeding of a two-year-old child after application of a hip spica cast is an appropriate task that the PN can delegate to a UAP. Feeding a stable patient is a routine task that does not require advanced nursing skills or clinical judgment. As long as the child is not at high risk for complications, this task can be safely delegated to a UAP with proper training and supervision.
Choice C rationale:
Evaluation of a client's incisional pain following narcotic administration is not an appropriate task to delegate to a UAP. This task requires clinical assessment, evaluation of medication effects, and critical thinking skills that are within the scope of practice of a PN, but not a UAP.
Choice D rationale:
Assessment of the placement and patency of a nasogastric feeding tube is not an appropriate task to delegate to a UAP. This task requires specialized nursing skills and clinical judgment to ensure the safety and effectiveness of the feeding tube. It is within the scope of practice of a PN, but not a UAP.
Correct Answer is C
Explanation
The correct answer is choice C: Leave the room after offering to return to the client's room at a later time.
Choice A rationale:
Consulting with the charge nurse about implementing suicide precautions is not appropriate in this situation. The client has not expressed suicidal ideation or intent, and such an action could be invasive and distressing for the client.
Choice B rationale:
Sitting quietly in the client's room until the client is ready to verbalize his feelings might seem supportive, but it disregards the client's request for alone time. It's essential to respect the client's wishes and provide an opportunity for self-reflection and privacy.
Choice C rationale:
Leaving the room after offering to return to the client's room at a later time is the most appropriate action. The client has requested solitude, and respecting his autonomy is crucial in building trust and rapport.
Choice D rationale:
Notifying a member of the client's family of the need to come stay with the client is not necessary at this point. The client's desire for alone time does not indicate an immediate need for family support. The practical nurse should first respect the client's request and give him space to process the news. If the client later expresses a need for family support, appropriate actions can be taken accordingly.
