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 C
Explanation
The correct answer is Choice C:
Gather the procedure tray and equipment. Choice A rationale:
Placing the client in an orthopneic position (sitting upright and leaning forward) is not necessary for a thoracentesis procedure. The position may be uncomfortable for the client and does not facilitate the procedure.
Choice B rationale:
Keeping the client NPO (nothing by mouth) and encouraging them to void before the procedure is not directly relevant to a thoracentesis. NPO status might be indicated for other procedures requiring anesthesia but not for a bedside thoracentesis.
Choice C rationale:
This is the correct choice. The PN should prepare by gathering the procedure tray and equipment before the healthcare provider arrives to perform the thoracentesis. This ensures that all necessary items are readily available for the procedure.
Choice D rationale:
Cleansing the site and covering it with a sterile towel is a task usually performed by the healthcare provider who will be performing the thoracentesis. The PN's role is to prepare the necessary equipment and assist the provider during the procedure.
Correct Answer is B
Explanation
The correct answer is choiceB. Culture for sensitive organisms.
Choice A rationale:
C-reactive protein (CRP) levels are indicative of inflammation in the body and can help identify the presence of an infection. However, CRP levels do not provide specific information about the type of organism causing the infection, which is crucial for targeted treatment.
Choice B rationale:
A culture for sensitive organisms is essential in this scenario because it identifies the specific bacteria or other pathogens present in the wound. This information is critical for selecting the appropriate antibiotic therapy to treat the infection effectively.
Choice C rationale:
Serum albumin levels are important for assessing nutritional status and overall health, which can impact wound healing. Low albumin levels can indicate poor nutritional status and delayed wound healing, but they do not provide immediate information about the infection itself.
Choice D rationale:
Serum blood glucose (BG) levels are crucial for managing diabetes and can affect wound healing. High blood glucose levels can impair the immune response and slow down the healing process. However, like CRP, BG levels do not provide specific information about the type of infection present in the wound.
