Chapter 42 : Caring for Clients With Eye Disorders Questions
Question 1 of 5
A client asks the nurse why miotic eye solutions were prescribed in the treatment of the client's glaucoma. Which is the best nursing rationale for the use of this medication?
Correct Answer: C
Rationale: A miotic agent works by constricting the pupil and pulling the iris away from the drainage channels so that the aqueous fluid can escape. These medications increase outflow and decrease intraocular pressure. Cycloplegics paralyze the ciliary muscles of the eye. Mydriatics drugs are used to dilate the pupil and are contraindicated in glaucoma.
Question 2 of 5
The nurse is caring for a client with open-angle glaucoma. What does the nurse know that this disease causes? Select all that apply.
Correct Answer: C,D,E
Rationale: Open-angle glaucoma occurs when structures in the drainage system (i.e., trabecular meshwork and canal of Schlemm) degenerate, and the exit channels for aqueous fluid become blocked. As the intraocular pressure (IOP) rises, it causes edema of the cornea, atrophy of nerve fibers in the peripheral areas of the retina, and degeneration of the optic nerve. This makes the other options incorrect.
Question 3 of 5
An older adult client is admitted with the diagnosis of retinal detachment and is scheduled for laser surgery and scleral buckling procedure. The nurse anticipates which symptom(s) to be exhibited in this client? Select all that apply.
Correct Answer: A,B
Rationale: Many clients with detached retina experience a sensation of a curtain or veil lowering over vision field, flashing of lights, floaters, cobwebs, or spots. Complete vision loss can occur in the affected eye. Loss of central vision, eye pain, and arcus senilis are not indicated in this disorder.
Question 4 of 5
A client is diagnosed with blepharitis. What symptoms should a nurse monitor in this client?
Correct Answer: A
Rationale: Blepharitis is an inflammation of the lid margins. The nurse monitors visible patchy flakes clinging to the eyelashes and about the lids. The condition does not cause redness or a halo around the pupil. In case of a sty, the nurse would observe a red pustule in the internal tissue of the eyelid.
Question 5 of 5
A nurse is assessing a client for a fracture to the bony orbit. What would the nurse document if the assessment for fracture was positive?
Correct Answer: D
Rationale: If the bony orbit is fractured, the eyes may appear asymmetric, and the client has diplopia or double vision. Excessive tearing, presence of rust rings, or blurry vision do not indicate a fractured bony orbit.
