Q

Eye med teaching

A

use as prescribed
wait 5-10 min between eye drop meds
don’t tough tip of application bottle to eye
wash hands before/after med admin
put pressure on corner of eye after eye drop instiled

25
Post-op eye teaching
avoid activities that increase IOP lift nothing over 10lb for over 1 week best vision not expected for 4-6 weeks
26
Gerontologic Considerations
tend to special needs of older adults | caution about potential drug interactions that occur with systemic illnesses and their treatments
27
Cataracts
``` opacity in lens that impair vision glare due to light scatter on lens occurs gradually, lower night vision no pain decreases V/A, blurred vision, double vision, absent red reflex, trouble seeing colors ```
28
Cataract causes
age, trauma, toxins
29
Cataract RN teaching
wear sunglasses and protect eyes during hazardous activities and get annual eye exams done
30
Cataract Tx
removal of lens with lens implant
31
Cataract Medications
anticholinergics: atropine | - prevents pupil contraction and has a long duration, fast onset
32
Cataract post op care
prevent increased IOP, prevent infection, eye drop medication, pain relief, self care, prevent falls/injury, cold compress
33
Otitis Media
ear infection | fever, decreased appetite, pulling at ears, sucking aggravates pain
34
Skin health promotion
avoid environmental hazards adequate hygiene and good nutrition skin self exams periodic professional exams of hard to see areas
35
Skin Environmental hazards
``` sun exposure UVA-tanning UVB-burning from sun high altitudes tanning booths allergens radiation nutrition (vitamin deficiency) ```
36
Nonmelanoma Skin Cancers
actinic keratosis: premalignant skin lesions Basal cell carcinoma: most common type of skin cancer, less deadly Squamos cell carcinoma: potential to metastasize, smoking, immunosuppression leads to increase in incidents
37
Dysplastic Nevus Syndrome
individual is at increased risk of developing melanoma | atypical moles larger than 5mm across
38
Malignant Melanoma
majority of skin cancer deaths from environmental and genetic factors
39
Malignant Melanoma Risk factors
``` red/blonde hair light colored eyes fair skin that freckles chronic sun exposure family hx ```
40
ABCDE Rule
``` Typically for diagnosing melanoma Asymmetry Border irregularity Color change Diameter >6mm Evolving appearance ```
41
Allergic Dermatologic Problems
Associated with allergies and hypersensitivity reactions family Hx and exposure patch testing avoid causative agent
42
Diagnostic and surgical therapies for dermatologic issues
``` skin scraping curettage punch biopsy cryosurgery excisions biopsy incisional biopsy ```
43
Control of Pruiritus
``` break the itch/scratch cycle cool environment hydration wet compress moisturizer topical drugs prevent spread ```
44
Skin viral infections
hard to treat, typically a lesion develops | ex: herpes and warts
45
Skin bacterial infections
occurs when a balance between host and microorganisms is altered
46
primary skin infection
occurs after there is a break in the skin | Staphylococcus is a common bacteria
47
secondary skin infection
already damaged skin or as a result to a systemic disease | Staphylococcus is a common bacteria
48
further investigation of mismatched socks
color blindness | problems dressing himself
49
importance of seeing a ophthalmologist
prevention eye changes like potential blindness aging can be a factor in vision change
50
nursing teaching for resistance to see provider
eye damage can impact daily activities Sx can worsen use active listening skills, why would someone be fearful -financial burden -bad experience gather more information about symptoms offer to make an appt for her and coordinate care
51
Hypertension, T2 diabetes, hyperlipidemia in response to Glaucoma
some medications for these diseases can cause increased IOP T2 diabetes can caused blindness Hyperlipidemia: limited blood flow
52
The nurse provides post instructions for an adult patient after cataract surgery. which written statement if provided by the nurse would be most appropriate? 1. to avoid contamination of the eye use aseptic technique when applying eyedrops 2. conjunctivitis may result if the eye is contaminated with wet or dirty eye patches 3. to prevent infection in the eye wash your hands before changing the eye patch of using eyedrops 4. coughing and bending over can cause increased IOP resulting in retinal damage or displacement of the intraocular lens
3. To prevent infection in the eye wash your hands before changing the eye patch or using eyedrops
53
The nurse instructs a patient with primary open angle glaucoma about the disorder. which statement is most appropriate? 1. the retinal nerve is damaged by an abnormal increase in the production of aqueous humor 2. aqueous humor cannot drain from the eye causing pressure damage to the optic nerve 3. as the lens enlarges with aging it pushes the iris forward covering the outflow channel of they eye 4. the lens blocks the pupillary opening preventing the flow of aqueous humor into the anterior chamber
2. aqueous humor cannot drain from the eye causing pressure damage to the optic nerve
54
etiology of blurred vision
etiology of blurred vision: refractive errors, corneal opacity, cataracts, migraines ora, retinal changes/retinal detachment/macular degeneration
55
etiology of diplopia
abnormal extra ocular muscle action related to muscle or cranial nerve pathologic condition
56
etiology of dryness
decreases tear formation or changes in tear composition due to aging or systematic diseases
57
etiology of pain
superficial corneal erosion or abrasion | can result from contact wear or trauma, conjunctival or foreign body
58
etiology of photophobia
inflammation or infection of cornea or anterior uveal track consists of your ciliary and iris body
59
etiology of spots/floaters
most common cause from vitreous liquefaction, benign phenomenon, hemorrage into virtuous humor, retinal holes or tears
