Chapter 42 : Caring for Clients With Eye Disorders Questions
Question 1 of 5
A client with chronic open-angle glaucoma is now presenting with eye pain and intraocular pressure of 50 mm Hg. An immediate iridotomy is scheduled. Which explanation by the nurse describes the desired effects of this procedure?
Correct Answer: C
Rationale: Laser iridotomy or standard iridotomy is a surgical procedure that provides additional outlet drainage of aqueous humor. This is done to lower the IOP as quickly as possible since permanent vision loss can occur in 1 to 2 days. Once optic nerve damage occurs, it cannot be reversed, and vision is not restored. Pain that occurs with rising IOP will be controlled once pressure is lowered through improved outflow drainage.
Question 2 of 5
A nurse is caring for a client scheduled for general anesthesia. Which assessment finding would contraindicate the use of atropine in this client?
Correct Answer: D
Rationale: Cholinergic blockers (such as atropine) are often used preoperatively to dry up secretions. Use of these drugs results in dilation of pupils, which increases intraocular pressure (IOP). Clients with glaucoma should avoid use of atropine in an effort to maintain normal range of IOP. Detached retina, CVA, and cataracts are insignificant in the use of cholinergic blockers.
Question 3 of 5
A nurse is caring for a client newly diagnosed with glaucoma. Which would be a priority in the nurse's teaching about maintaining normal pressure range in the eye?
Correct Answer: A
Rationale: Adding fiber to the diet will increase ease of bowel movements and prevent constipation and straining, which can inadvertently increase intraocular pressure. Eating small meals is insignificant in maintaining intraocular pressure. Avoid over-the-counter treatment of cold and allergy symptoms if contains cholinergic blockers. Reading is not significant in changing intraocular pressure, but eye strain should be avoided.
Question 4 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 5 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.
