Chapter 51: Eye and Vision Disorders MULTIPLE CHOICE 1. The 60-year-old patient who has had an enucleation asks when he can get his prosthesis fit-ted. The nurse responds that the prosthesis will be fitted by an optician in approximately: 1. 2 weeks. 2. 4 weeks. 3. 8 weeks. 4. 12 weeks. ANS: 2 After an enucleation, the patient is fitted with a prosthesis in 1 month.

The patient who has been taking opioid medication for postoperative pain exhibits pinpoint pupils. The anatomic portion of the eye that has been affected by the medication is the: 1. sclera. 2. retina. 3. choroid. 4. bulbar conjunctiva. ANS: 3 The choroid of the eye contains the pupil and iris.

The nurse explains that the portion of your eye that will make it possible for you to see in a darkened environment is the: 1. macula. 2. rods. 3. cones. 4. optic nerve. ANS: 2 The eye uses rods to accommodate to dim light. Cones are the color receptors. The optic nerve transmits to the brain all sensory input from the eye.

When being interviewed, a 50-year-old patient says that he cannot see the newspaper as well as he used to. You know that vision changes from near to far because:
1. the ciliary muscle changes the pupil size. 2. the lens of the eye changes shape as a muscle contracts and relaxes. 3. of nearsightedness. 4. of clouding of the vitreous humor. ANS: 2 Accommodation or adjustment of the lens by contraction and expansion of the ciliary muscle allows us to see far or near.

During the initial assessment of a very thin patient at the eye clinic, the nurse notes that the patient has very prominent eyes. The nurse should inquire about a history of: 1. diabetes. 2. glomerulonephritis. 3. Graves’ disease. 4. hypertension. ANS: 3 The appearance of the patient and the prominence of the eye (exophthalmos) would lead the nurse to inquire about a thyroid disorder, most likely Graves’ disease or hyperthyroidism.

When you ask your patient about his vision, he says that the last time he had it tested, it was recorded as 20/50.
