Test #4 Flashcards
What is the pathophysiology of cataracts?
Clouding of the lens due to protein clumping, blocking light passage.
List the clinical symptoms of cataracts.
- Blurred or foggy vision
- Increased glare sensitivity (especially at night)
- Dulled color perception
- Difficulty reading or driving
What nursing considerations should be taken for patients with cataracts?
- Assess safety risks: Ensure the patient has adequate lighting and avoids fall hazards.
- Reinforce preoperative teaching if surgery is scheduled.
- Postoperative care: Avoid straining (coughing, lifting heavy objects).
What should be administered for prescribed eye care?
Antibiotics and anti-inflammatory drops
Administer prescribed eye drops as directed.
What are the signs and symptoms of complications to educate on?
Infection, increased pain, vision loss
Educate patients to recognize these symptoms early.
What is the pathophysiology of Open-Angle Glaucoma?
Increased intraocular pressure (IOP) due to reduced aqueous humor drainage, leading to optic nerve damage
Understanding the underlying mechanism is crucial for management.
What is a clinical symptom of Open-Angle Glaucoma?
Gradual loss of peripheral vision (‘tunnel vision’)
This symptom is often painless and progressive.
What are nursing considerations for medication management in Open-Angle Glaucoma?
Reinforce adherence to lifelong treatment with pilocarpine or beta-blockers
Consistent medication use is essential to manage the condition.
What systemic effects should be monitored when using Pilocarpine?
Blurred vision, headache, diarrhea
These effects can impact patient quality of life.
What systemic effects should be monitored when using Beta-blockers?
Heart rate, blood pressure
Beta-blockers like timolol can have significant cardiovascular effects.
What post-laser trabeculoplasty care instructions should be given?
Monitor for pain and pressure changes; advise no heavy lifting or bending over
These precautions help prevent complications post-procedure.
What is the pathophysiology of Retinal Detachment?
The retina separates from its blood supply, leading to vision loss
Understanding this helps in recognizing the urgency of the condition.
What is a clinical symptom of Retinal Detachment? I
Flashes of light (‘photopsia’), floaters or cobweb-like shadows
These symptoms indicate that immediate medical attention may be necessary. Iii
