NCLEX Review About The Aging Eye

41. Tonometry is performed on the client with a suspected diagnosis of glaucoma. The nurse analyzes the test results as documented in the client's chart and understands that the normal intraocular pressure is:

a) 2 to 7 mm Hg
b) 10 to 21 mm Hg
c) 22 to 30 mm Hg
d) 31 to 35 mm Hg

42. The nurse is preparing a teaching plan for a client who is undergoing cataract extraction with intraocular implantation. Which home care measures will the nurse include in the plan? Select all that apply

a) avoid activities that require bending over
b) contact the surgeon if eye scratchiness occurs
c) place an eye shield on the surgical eye at bedtime
d) episodes of sudden severe pain in the eye are expected
e) contact the surgeon if a decrease in visual acuity occurs
f) take acetaminophen (Tylenol) for minor eye discomfort



43. The client is receiving an eye drop and eye ointment to the right eye. The nurse should:

a) administer the eye drop first, followed by the eye ointment
b) administer the eye ointment first, followed by the eye drop
c) administer the eye drop, wait 10 minutes, and administer the eye ointment
d) administer the eye ointment, wait 10 minutes, and administer the eye drop

44. The nurse is caring for a client with glaucoma. Which of the following medications, if prescribed for the client, would the nurse question?

a) carbachol (Carboptic)
b) atropine sulfate (Isopto Atropine)
c) pilocarpine (Ocusert Pilo-20, Ocusert Pilo-40)
d) pilocarpine hydrochloride (Isopto Carpine)

45. A miotic medication has been prescribed for the client with glaucoma. The client asks the nurse about the purpose of the medication. The nurse tells the client that:

a) the medication will help dilate the eye to prevent pressure from occurring
b) the medication will relax the muscles of the eyes and prevent blurred vision
c) the medication causes the pupil to constrict and will lower the pressure in the eye
d) the medication will help block the responses that are sent to the muscles in the eye




NCLEX REVIEW ABOUT THE AGING EYE:
ANSWERS AND RATIONALE

41) B

- Tonometry is the method of measuring intraocular fluid pressure using a calibrated instrument that indents or flattens the corneal apex. Pressures between 10 and 21 mm Hg are considered within the normal range.

42) A, C, E, F

- Following eye surgery, some scratchiness and mild eye discomfort may occur in the operative eye and usually is relieved by mild analgesics. If the eye pain becomes severe, the client should notify the surgeon because this may indicate hemorrhage, infection, or increased intraocular pressure. The nurse also would instruct the client to notify the surgeon of increased purulent drainage, increased redness, or any decrease in visual acuity. The client is instructed to place an eye shield over the operative eye at bedtime to protect the eye from injury during sleep and to avoid activities that increase intraocular pressure, such as bending over.

43) A

- When an eye drop and an eye ointment are scheduled to be administered at the same time, the eye drop is administered first. Options B, C, and D are incorrect.

44) B

- Options A, C, and D are miotic agents used to treat glaucoma. Option B is a mydriatic and cycloplegic medication, and its use is contraindicated in clients with glaucoma. Mydriatic medications dilate the pupil and can cause an increase in intraocular pressure in the eye.

45) C

- Miotics cause pupillary constriction and are used to treat glaucoma. They lower the intraocular pressure, thereby increasing blood flow to the retina and decreasing retinal damage and loss of vision. Miotics cause a contraction of the ciliary muscle and a widening of the trabecular meshwork. Options A, B, and D are incorrect.
