Answer to Question 1

ANS: A
The Jaeger card is used to assess near vision problems and presbyopia in persons over 40 years of age. The card should be held 14 inches away from eyes while the patient reads words in various print sizes. Using a penlight to determine pupil change is testing pupil response. A short burst of air may be used to test intraocular pressure but is not used for testing presbyopia. Covering one eye at a time while reading a wall chart at 20 feet describes the Snellen test.

Answer to Question 2

ANS: B
Fluorescein angiography involves injecting IV dye. If extravasation occurs, fluorescein is toxic to the tissues. The patient should be instructed to report any signs of extravasation such as pain or burning. The nurse should closely monitor the IV site as well. The cornea is anesthetized during ultrasonography. Refractometry involves measuring visual acuity and asking the patient to choose lenses that are the sharpest; it is a painless test. The Amsler grid test involves using a hand held card with grid lines. The patient fixates on the center dot and records any abnormalities of the grid lines.
