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 D
Explanation
The correct answer is Choice D. What are the voices uttering?
Choice A rationale:
While it is essential to assess how the client copes with auditory hallucinations, asking this question alone does not provide specific information about the content of the hallucinations. Knowing what the voices are saying is vital in understanding the nature and potential impact of the hallucinations.
Choice B rationale:
Knowing when the voices are most disturbing can provide some insights into the pattern of the auditory hallucinations. However, this information alone may not fully address the client's current experience or their response to the hallucinations.
Choice C rationale:
Inquiring about which medication works best is important, but it should come after understanding the nature of the hallucinations. Medication management is a crucial aspect of treating schizophrenia, but gathering information about the content of the hallucinations helps in formulating an appropriate treatment plan.
Choice D rationale:
The correct choice. Knowing what the voices are uttering is essential in assessing the severity and potential impact of the auditory hallucinations on the client's well-being. This information will guide the healthcare team in providing targeted interventions and support to manage the symptoms effectively.
Correct Answer is ["40"]
Explanation
The client’s 0730 finger stick glucose is 271 mg/dL. According to the sliding scale parameters, the client should receive:
Step 1: Determine the amount of insulin aspart based on the sliding scale. Since the glucose level is 271 mg/dL, which falls in the range of 270 to 300 mg/dL, the client should receive 15 units of insulin aspart.
Step 2: Add the amount of NPH insulin to the amount of insulin aspart. The client has a prescription for NPH insulin 25 units before breakfast. So, the total amount of insulin this client should receive is 25 units (NPH insulin) + 15 units (insulin aspart) = 40 units.
So, the total amount of insulin this client should receive is40 units.
