Study Notes

Nursing Care and Patient Considerations

Legally blind patients require adaptations in care to ensure safety and effective communication.
Chemical splashes in the eyes necessitate immediate irrigation to prevent damage.
Tympanoplasty corrects issues related to the eardrum or middle ear function.
Symptoms like grittiness, blurred vision, and stringy mucus post-eye surgery may indicate an infection or irritation.
Post-stapedectomy hearing improvements may not be immediate and require reassurance and monitoring.
Common communication barriers with hearing-impaired individuals include speaking too quickly or not facing them.
Lens curvature adjustment for focusing on the retina is called accommodation.
Resources such as local blind associations can assist newly blind individuals in gaining support.
LASIK differs from PRK in that LASIK involves creating a flap in the cornea.
Phacoemulsification is a cataract removal procedure that uses ultrasound to break up the lens.
Blurred vision and halos around lights may signal cataracts in older patients.
Post-cataract repair patients should avoid heavy lifting and eye strain.
Diabetic retinopathy stems from prolonged high blood sugar levels affecting the retina.
Flashing lights and curtain-like vision loss may signal retinal detachment.
Assess for headaches and chewing difficulties in older adults; potential temporomandibular joint issues can arise.
Weber test results indicating conductive hearing loss show the tone heard better in the affected ear.
Hearing aid whistling may require checking for fit or obstruction.
Advise patients on appropriate hydration when treated for otitis media to prevent dehydration.
Encourage patients with labyrinthitis to rest and limit movements.
Miotic eye drops help reduce intraocular pressure in glaucoma patients.
Care for tympanoplasty should include monitoring for signs of infection and maintaining ear hygiene.
Amsler grid testing helps monitor central vision; report any changes in squares or lines.
Post-enucleation care includes emotional support and prosthetic eye discussions.
After vitrectomy, patients should avoid activities that might induce eye strain.
Photocoagulation treats diabetic retinopathy by sealing blood vessels.
The first indication of macular degeneration is usually blurred or distorted central vision.
Signs of acute angle closure glaucoma include severe ocular pain and headache.
The structure of children’s Eustachian tubes makes them more prone to otitis media.
Protecting eyes during UV lamp use prevents retinal damage and cataract formation.
High-volume music can lead to noise-induced hearing loss, particularly in adolescents.
The eye's most interior part is the retina.
Immediate care for penetrating eye injuries prioritizes protecting the eye and preventing further damage.
Conditions causing conductive hearing loss include earwax buildup, fluid in the ear, and ear infections.
Contributing factors to otitis media include allergies and respiratory infections.
Consider individual learning styles and readiness when educating patients with sensory impairments.
Common cataract causes include aging, diabetes, and prolonged steroid use.
In the PACU after stapedectomy, the nurse should assess vital signs and hearing function.
When assisting a blind person in unfamiliar settings, offer a guide arm and describe surroundings.

Symptoms and Diagnosis

Tearing and redness indicate possible entropion or ectropion in eye assessments.
Pneumatic retinopexy uses gas bubbles to apply pressure for retinal detachment repairs.
Total eye removal is termed enucleation.
A tympanostomy means creating an incision in the eardrum for pressure relief.
Progressive deafness from stapes ankylosis is termed otosclerosis.

Neurological Assessments

The nervous system divides into the central and peripheral systems.
The vagus nerve controls many thoracic and abdominal organs, regulating vital functions.
Patients with head injuries and signs of deterioration should be positioned to maintain airway patency.
Open-ended questions improve the validity of patient responses regarding neurological issues.
A key indicator of increased intracranial pressure is a change in consciousness.
The FOUR score coma scale evaluates eye response, brainstem reflexes, motor response, and respiration.
Spatial awareness deficits after a stroke relate to body schema perception.
Myelogram preparation should involve hydration and assessing allergy history regarding contrast media.
Stroke patients with dysphagia may benefit from thickened liquids to prevent aspiration.
Surgical navigational systems assist in precise positioning during operations.

The first sign of Bell's palsy is typically facial droop or weakness.
Myelogram post-care involves monitoring for headache and neurologic symptoms.

Foods high in tyramine can trigger migraine headaches and should be avoided.
Cushing response signs include hypertension, bradycardia, and irregular respirations.
Feeding techniques for hemiplegic patients include positioning and portion control for safety.
The reticular activating system (RAS) is vital for consciousness and wakefulness regulation.
