PrepU: Chapter 16-Eyes

The functional reflex that allows the eyes to focus on near objects is termed

Accomodation.

A light is pointed at a client's pupil, which then contracts. It is also noted that the other pupil contracts as well, though it is not exposed to bright light. Which of the following terms describes this latter phenomenon?

Consensual reaction.

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.

A left temporal hemianopsia.

What technique by the nurse demonstrates proper use of the ophthalmoscope?

Asks the client to fix the gaze upon an object and look straight ahead.

An adult client tells the nurse that his eyes are painful because he left his contact lenses in too long the day before yesterday. The nurse should instruct the client that prolonged wearing of contact lenses can lead to

Corneal damage.

A client has been diagnosed with astigmatism. The nurse should be prepared to teach the client about which treatment for this condition?

Corrective lens.

A client frequently experiences dry, irritated eyes. These findings are consistent with a problem in what part of the eye?

Lacrimal apparatus.

A patient complains of feeling like he is slowly losing his central vision. The nurse knows this symptom could represent

Which statement demonstrates the safest way to document assessment findings of drainage noted in both eyes of a client?

Thick, purulent drainage is noted at inner corner of both eyes.

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

True.

How can a nurse accurately assess the distant visual acuity of a client who is non-English speaking?

Use a Snellen E chart to perform the examination.

A client is concerned because the sclera of the right eye has been pink in color for several days and tearing. What should the nurse suspect is occurring with this client?

Conjunctivitis.

A client visits the health care clinic with reports of itchy and watery eyes for three days. The nurse observes a generalized redness to the conjunctiva. The nurse recognizes this as what condition?

Conjunctivitis.

Up.

White-colored.

Which of the following statements most accurately describes the maintenance of normal intraocular pressure?

Aqueous humor is continuously circulating through the eye with production equalling drainage.

A client performs the test for distant visual acuity and scores 20/50. How should the nurse more accurately interpret this finding?

At 20 feet form the chart, the client sees what a person with good vision can see at 50 feet.
