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 choice B. Attach the drainage bag to the bed frame.
Choice A rationale:
Measuring the urinary output in the bag is a routine task but does not address the improper placement of the drainage bag. The immediate concern is to ensure the drainage bag is correctly positioned to prevent complications.
Choice B rationale:
Attaching the drainage bag to the bed frame is the correct action. The drainage bag should be kept below the level of the bladder and attached to a non-movable part of the bed to prevent backflow and reduce the risk of infection.
Choice C rationale:
Applying gloves and emptying the drainage bag is not the immediate priority. The drainage bag should not be allowed to overfill, but in this scenario, it is only half-full, so this action is not urgent.
Choice D rationale:
Removing the looped tubing from the bed is important to ensure proper drainage and prevent backflow, but it does not address the incorrect placement of the drainage bag, which is the primary concern in this situation.
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.
