4. Ptosis - ANSWER ANS: 2
Diplopia, or double vision, is the primary symptom of strabismus. Nystagmus is a
disorder that causes involuntarily rhythmic movements in the eye. Aphakic vision
occurs when the lens of the eye is removed. Ptosis is drooping of the eyelid.

any pain. The nurse suspects the client is experiencing:
1. glaucoma.
2. cataracts.
3. macular degeneration.
4. retinal detachment. - ANSWER ANS: 2
Cloudy changes in the opacity of the lens cause cataracts to result in blurred vision. It
occurs in both eyes, one usually worse than the other. Glaucoma, macular
degeneration, or retinal detachment is not accompanied by gradual eye blurring.
3. A client is diagnosed with glaucoma. The nurse should instruct the client that the
purpose of medication is to:
1. help dry up excess secretions.
2. lower the intraocular pressure.
3. strengthen the muscles of the eye.
4. improve the vision of the eye. - ANSWER ANS: 2

reading of 25 mmHg is not low or normal. Medication can be ordered to lower the
pressure.
6. A client has been diagnosed with cataracts. The nurse understands that the only
treatment for this disorder is?

Cataracts cannot be treated by medication. Cryopexy and phototherapy are not forms of
treatments for cataracts.
7.Which of the following should the nurse assess in a client with the diagnosis
open-angle glaucoma?
