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 B
Explanation
The correct answer is Choice B. Report the finding to the charge nurse. Choice A rationale:
Checking for kinks in the drainage tubing is an important troubleshooting step if there is a sudden decrease or absence of urine output. However, in this case, the PN's concern is the presence of thick red fluid with clots in the urine drainage. This finding indicates potential bleeding, which requires immediate attention and reporting.
Choice B rationale:
Reporting the finding to the charge nurse is the correct action. The presence of thick red fluid with clots in the urine suggests significant bleeding after the transurethral resection of the prostate (TURP) surgery. It is crucial to inform the charge nurse or the healthcare provider promptly so that appropriate interventions can be initiated to address the bleeding.
Choice C rationale:
Stopping the irrigation solution immediately may not be within the PN's scope of practice unless explicitly instructed by the healthcare provider. Moreover, abruptly stopping the irrigation may lead to complications, and it is essential to involve the charge nurse or healthcare provider in making this decision.
Choice D rationale:
Observing the drainage again in one hour is not appropriate in this situation. The presence of thick red fluid with clots in the urine drainage is an urgent concern that requires immediate action, not a wait-and-see approach.
Correct Answer is A
Explanation
The correct answer is Choice A:
"Are you planning to obey the voices?.”. Choice A rationale:
The PN should ask the client if he plans to obey the voices because it helps assess the potential risk of harm to himself or others. If the client indicates an intention to follow the voices' commands to harm someone, it indicates a serious concern for safety and may require immediate intervention to protect the client and others.
Choice B rationale:
While asking if the client believes the voices are real is important for understanding the client's perception of the situation, it may not immediately address the risk of harm that the client or others might be facing.
Choice C rationale:
Asking if the client has taken any hallucinogens is relevant to explore possible substance- induced psychosis, but this question should be asked later in the assessment process. The priority is to assess immediate safety concerns related to the client's compliance with the voices' instructions.
Choice D rationale:
Inquiring about when the voices began is important, but it is not the most urgent question in this situation. Although the onset of the symptoms is relevant, addressing the potential for harmful actions should be prioritized.
