Chapter 42 : Caring for Clients With Eye Disorders Questions
Question 1 of 5
An older adult client is scheduled for cataract surgery and asks the nurse, 'Will I need to wear thick lenses after surgery?' Which is an appropriate response from the nurse?
Correct Answer: A
Rationale: Vision is usually restored after cataract surgery with an intraocular lens implant. Contact lenses can be used but can be burdensome for older adults. Corrective glass lenses can cause a distortion of peripheral vision and only one lens is required (over operative eye).
To restore vision after cataract surgery, a lens is required.
Question 2 of 5
A nurse is caring for a client immediately following cataract removal. Which symptom would be most alarming to the nurse?
Correct Answer: C
Rationale: Coughing can rise the intraocular pressure and should be avoided. A cough suppressant can be prescribed. The pupil was intentionally dilated during the surgical approach and will resolve. The client may complain of mild eye irritation in the immediate postoperative period. Fever can be a complication of cataract surgery but not expected in the immediate period postoperatively.
Question 3 of 5
Following cataract removal, the client receives discharge instructions from the nurse. Which of the following instructions is most important?
Correct Answer: D
Rationale: For at least 1 week, the client should avoid strenuous activity and heavy lifting; bending, stooping, or other exercises that potentially increase intraocular pressure; immersing the eyes in water (clients may use a clean damp cloth to remove any eye discharge); and any activity that could cause dust or other particles to lodge in the eye. Clients may sleep on the back or unaffected side. The client should wear a protective eye shield for 24 hours after the procedure and then at night and during naps for about a week.
Therefore, it is insufficient for the nurse to instruct the client to wear a protective shield at bedtime.
Question 4 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 5 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.
