MULTIPLE CHOICE

 

1. A client is diagnosed with strabismus. Which of the following will the client most likely experience with this disorder?

1.	Nystagmus
2.	Diplopia
3.	Aphakic vision
4.	Ptosis

 

 

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.

2. A client is experiencing a gradual blurring of vision in both eyes not associated with any pain. The nurse suspects the client is experiencing:

1.	glaucoma.
2.	cataracts.
3.	macular degeneration.
4.	retinal detachment.

 

 

ANS:  2

Cataracts occur as the opacity of the lens becomes cloudy, blurring the vision. It occurs in both eyes but is usually worse in one eye. Gradual eye blurring is not associated with glaucoma, macular degeneration, or retinal detachment.

3. The nurse should instruct a client, diagnosed with glaucoma, 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 in the eye.

 

 

ANS:  2

Glaucoma is a disease that relates to the increase of intraocular pressure. The medication given will decrease this intraocular pressure. Medication for glaucoma is not used to help dry up excess secretions, strengthen the eye muscles, or improve vision.

4. After surgery to remove a cataract, which of the following should the nurse instruct the client?

1.	“Be sure to follow the schedule for the prescribed eyedrop medication.”
2.	“Sleep on the right side to promote drainage.”
3.	“It is okay to rub the eye because the surgery was on the inside.”
4.	This is an outpatient procedure, and there are no instructions for the patient.

 

 

ANS:  1

Client education is extremely important in the aftercare of cataract surgery. There is a need to emphasize the postoperative care of eyedrop instillation. The client should not place any pressure near or on the eye. Postoperative instructions are highly important for the client having an outpatient surgical procedure.

5. A tonometry test has been performed with a client and the results are 25 mmHg. The nurse know that:

1.	the reading is low and there is no problem.
2.	the reading is normal and nothing needs to be done at this time.
3.	the results are high and follow-up readings and tests are needed.
4.	the results are high and there is no cure to bring the pressure down.

 

 

ANS:  3

Several reading need to be taken throughout the day to establish the highest reading to be the treated pressure. Normal intraocular pressure ranges from 12 to 16 mmHg. The reading of 25 mmHg is not low or normal. Medication can be prescribed to reduce the pressure.
