A client is scheduled for a thoracentesis that will be done at the bedside. What should the practical nurse (PN) prepare before the healthcare provider arrives on the unit to perform the procedure?

The correct answer is choice D, Pupils reactive to accommodation. Choice A rationale:

"Peripheral vision intact”. refers to the ability to see objects at the outer edges of one's visual field. It is not relevant to the assessment of pupillary response and does not describe the finding of pupils constricting as they change focus from a far object to a near object.

Choice B rationale:

"Nystagmus present with pupillary focus”. suggests involuntary rapid eye movements accompanied by changes in pupillary response. Nystagmus is not an expected finding during pupillary accommodation, and its presence would indicate a neurological issue rather than a normal response.

Choice C rationale:

"Consensual pupillary constriction present”. refers to both pupils constricting when light is shined into one eye. While this finding is normal, it does not specifically describe the pupils' response during accommodation when focusing from a far object to a near object.

Choice D rationale:

"Pupils reactive to accommodation”. accurately describes the normal physiological response of the pupils constricting as they change focus from a distant object to a nearby object. This response ensures that the appropriate amount of light enters the eyes to maintain clear vision during different distances of focus.

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:

1. 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.
2. 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.
3. 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.
4.
