B)  optic nerve. 
C)  vitreous body.

Question 2

Accepted Answer

A)  Cataracts 
B)  Presbyopia 
C)  Glaucoma 
D)  Astigmatism

B)  Presbyopia

Question 3

Sutures used in ophthalmic surgery are very fine and range in size from 4-0 to 10-0.Handling and arming these sutures can be a challenge for the perioperative nurse with uncorrected presbyopia.Eye sutures should be handled as little as possible to avoid:

Accepted Answer

A)  weakening and fraying. 
B)  causing the formation of needle burrs. 
C)  losing sutures among the drapes or on the floor. 
D)  reaction and discomfort for the patient.

B)  causing the formation of needle burrs. 
C)  losing sutures among the drapes or on the floor. 
D)  reaction and discomfort for the patient.

Question 4

The procedure for cataract extraction with implantation of an intraocular lens (IOL)exposes the patient to risks of infection of the anterior chamber and corruption of the implanted device.Appropriate measures for the circulating nurse and scrub person include managing patient safety needs.Efforts are directed at preventing foreign substances from being introduced intraocularly.Select all of the nursing actions that may ensure this outcome.

Accepted Answer

A) The sterile field should be created with lint-free drapes. 
B) Powder-free gloves should be worn. 
C) Instruments should be cleaned with gauze sponges. 
D) Gloved hands should not touch the intraocular tip of the instrument. 
E) Instruments should be soaked in sterile water when not in use.f.The procedure room should be warm,quiet,and peaceful.

Question 5

Patients presenting for ophthalmic surgery may have endured chronic progressive impairment,or recent decrease,in visual acuity.Most patients are admitted through an ambulatory admission area adjacent to the surgical suite.Select an appropriate nursing action(s)when admitting the ophthalmic surgery patient.

Accepted Answer

A)  Fully orient the patient to the physical surroundings. 
B)  Use detailed descriptions and reinforce them. 
C)  Approach the patient from the unaffected side to avoid startling the patient. 
D)  All of these interventions are appropriate for the ophthalmic surgery patient.

Question 6

Select the appropriate procedure performed for a patient with Fuchs' dystrophy,edema after cataract surgery,or keratoconus (abnormal steepening)of the cornea.

Accepted Answer

A)  Keratoplasty 
B)  Keratorefraction 
C)  Laser epithelial keratomileusis 
D)  Laser-assisted in-situ keratomileusis 
A)  Keratoplasty 
B)  Keratorefraction 
C)  Laser epithelial keratomileusis 
D)  Laser-assisted in-situ keratomileusis

Question 7

The nurse must ensure that the microscope used in ophthalmic surgery is specifically intended for safe use in eye surgery.The perioperative nurse must also be familiar with adjusting the pupillary distance (distance between pupils of the user's eyes)and diopter settings on the oculars (eyepieces)for operator vision correction to work without eyeglasses.How should the oculars be set for a user with astigmatism?

Accepted Answer

A)  Set the oculars to the same diopters as the user's corrective lenses. 
B)  Set the oculars to the half setting of the diopters of the user's corrective lenses. 
C)  Set the oculars at zero;users should wear their eyeglasses. 
D)  None of these options are appropriate for a user with astigmatism.
