FINAL Flashcards
(52 cards)
Nursing Diagnoses for Vision Deficits
- Risk for injury
- Self-care deficits
- Acute Pain
- Noncompliance (with meds)
- Anxiety (regarding surgery)
Cataract definition
Opacity within the lens of one or both eyes
Cataract etiology
usually age related. May be related to trauma, congenital factors, UV light, or DM
Cataract diagnosis
- decreased vision
- abnormal color perception
- glare
- symptoms may be worse at night
Cataract diagnosis
-decreased visual acuity and visual observations by eye exam
Cataract treatment
- No cure
- surgical removal
- first try palliative measures: visual aids, adjust lifestyle, don’t drive at night
Care
Assess good eye before surgery to see how they will function after surgery
- teach about surgery
- help with anxiety
- make sure someone can drive them home
- no food 6-8 hrs before surgery
- Eye drops to decrease swelling
- wear sunglasses after using eyedrops
- minimal pain: manage with tylenol
Interventions
- side effects for drugs
- instill eye drops
- safety issues (modify env)
Elderly concerns
- dexterity to put in eye drops
- memory
- falls
- polypharmacy
Glaucoma definition
- Characterized by increase in IOP
- consequence of elevated pressure
- optic nerve atrophy
- peripheral visual field loss
- increases with age
- NORMAL IOP: 18-22 mmHg
2 types of glaucoma
open angle (POAG) Closed angle (PACG)
Diagnosis of Glaucoma
- IOP elevation over 22 mmHg
- Optic disc cupping in open angle glaucoma
- decreased peripheral vision and visual acuity
Glaucoma Care
Primary focus is to keep pressure low and to manage the symptoms
Interventions for glaucoma
- teach risks
- screen
- meds
- home safety
- assess self care and need for help
Primary open angle glaucoma definition
- most common type
- outflow of aqueous humor is decreased in the trabecular meshwork
- drainage channels become clogged and damage to optic nerve can result
- presents slowly with no symptoms, pain or pressure
- gradual visual field loss
- Tunnel vision with peripheral vision absent
Treatment: open angle glaucoma
- drug therapy
- drugs help decrease pressure
- Laser therapy: lower IOP, stimulates constriction of trabecular meshwork which opens outflow channels
Primary angle closure glaucoma definition
- reduction in the outflow of aqueous humor that results from angle closure
- usually caused from lens bulging forward as a result of aging
- sudden, excruciating pain in or around eye
- N & V
- Seeing halos around lights
- blurred vision
- ocular redness
- frosted cornea
- ocular emergency: use drugs first but surgery is necessary
Secondary glaucoma
- increased IOP due to other ocular or systemic condition (inflammation/trauma/tumors)
- treat underlying problem first and use antiglaucoma drugs
- Failure of treatment can progress to full glaucoma
Osteoarthritis
- most common form of joint disease
- not a normal part of aging
- slowly progressive NON-INFLAMMATORY disorder of synovial joints
- Cartilage and and other joint structures deteriorate causing bones to pull together and rub against each other
Primary osteoarthritis
occurs idiopathic
Secondary osteoarthritis
-Caused by known event (trauma) that damages cartilage or joint
Osteoarthritis symptoms
- no systemic manifestations like RA
- pain, local to one joint, loss of ROM
- Pain worsens with joint use or when barometric pressure changes
- Joint stiffness after rest
- Deformity: nodules on joints from osteophyte formation
Osteoarthritis diagnosis
- based on patient symptoms and complains
- Xrays are sometimes useful but may not show changes until they are major
Osteoarthritis treatment goal
- decrease pain
- treat with rest, joint protection, heat/cold, nutritional therapy, exercise, drug therapy
