Aqueous humor is a clear liquid substance produced by the ciliary body that fills the anterior and posterior chambers of the eye. It helps to cleanse and nourish the cornea and lens as well as maintain intraocular pressure. Lacrimal and meibomian refer to glands that produce tears and a lubricating substance of the eyelids, respectively, and not to types of humor.)

Place an opaque card in between the eyes of the client Explanation: The nurse should place an opaque card in between the eyes of the client when assessing the client for consensual response to avoid inaccurate results. The light should not be focused directly into the eye to be tested; it should be focused obliquely into one eye, and the response should be checked in the other eye. The client should not be instructed to close the other eye not focused with light because the response is checked in the other eye.

Consensual Reaction

The nurse notes that the pupil of a client's left eye constricts when a light is shined into the right eye. How should the nurse document this finding?

Consensual light response present in left eye

While the nurse examines a patient's pupillary response to light in the right eye, the pupil in the left eye is constricted. What does this finding suggest to the nurse?

Consensual reaction

When assessing risk factors for eye and vision problems, the nurse knows that genetics can play a role. What major eye problem are clients most likely at increased risk for if a first-degree relative has it?

Glaucoma

A client reports the appearance of rings around lights. A nurse should perform further assessment to confirm the onset of what disorder? a) Glaucoma b) Cataract c) Diabetes d) Hypertension

Glaucoma Explanation: Seeing rings around lights or halos is associated with narrow angle glaucoma. Diabetes produces change in the retina that can cause blurred vision. Cataracts are caused by clouding of the lens of the eyes. Hypertension affects the blood vessels of the eyes which may not cause any eye symptoms until the damage is severe.

Hyphema Explanation: Hyphema is blood in the anterior chamber of the eye, usually caused by blunt trauma. Blepharitis is inflammation of the margin of the eyelid. Chalazion is a cyst in the eyelid. Iris nevus is a rare condition affecting one eye. The latter 3 conditions are not commonly attributed to blunt force trauma to the head as hyphema is.

She can see at 20 feet what a normal person could see at 100 feet

Which statement demonstrates the safest way to document assessment findings of drainage noted in both eyes of a client? a) Thick, purulent drainage is noted at inner corner of OU. b) Thick, purulent drainage is noted at inner corner of both eyes. c) Thick, purulent drainage is noted at inner corner of OS. d) Thick, purulent drainage is noted at inner corner of OD.

Thick, purulent drainage is noted at inner corner of both eyes Explanation: The abbreviations OD (right eye), OS (left eye), and OU (both eyes) are no longer used due to the potential for order errors. Instead, it is recommended to use "right eye," "left eye," or "both eyes." (less) Reference: Weber, J., and Kelley, J. Health Assessment in Nursing, 5th ed., Philadelphia: Wolters Kluwer Health, 2014, Chapter 16: Assessing Eyes, pg. 328.

A nurse is inspecting a client's eyes to assess for the possibility of detached retinas. The nurse is aware that which of the following is the function of the retina? a) Permits the entrance of light to the eye b) Transforms light rays into nerve impulses that are conducted to the brain c) Controls the amount of light entering the eye d) Refracts light rays onto the posterior surface of the eye

Transforms light rays into nerve impulses that are conducted to the brain Explanation: Visual perception occurs as light rays strike the retina, where they are transformed into nerve impulses, conducted to the brain through the optic nerve, and interpreted. The lens functions to refract (bend) light rays onto the retina. Muscles in the iris adjust to control the pupil's size, which controls the amount of light entering the eye. The cornea permits the entrance of light, which passes through the lens to the retina.

The nurse tests the six cardinal directions to test extraocular movement of the eye.

True

An adult client tells the nurse that he has been experiencing gradual vision loss. The nurse should

check the clients blood pressure

ultraviolet light exposure. Explanation: Exposure to ultraviolet radiation puts the client at risk for the development of cataracts (opacities of the lenses of the eyes). Consistent use of sunglasses during exposure minimizes the client's risk.
