Q

Chalzion

A

Oil gland of eyelid becomes block and forms a swollen bump or pustule

30
Q

Hordeolum

A

“Style” red tender bump on eyelid from blocked oil duct

31
Q

Glaucoma

A

Increased intraocular pressure
Excessive pressure can damage optic Nerve
Assessment- loss of vision or blind spot
Eye drops usually prescribed

32
Q

Hyphema

A

Bleeding into anterior portion of eye from trauma that obscures Vision partially or completely
Management- If hyphema is suspected take spinal precautions and elevate head to 40 degrees to decrease IOP
Antiplatelets should be avoided

33
Q

Iritis

A

Inflammation of iris

Assessment- redness of the eye, cloudy vision or unusual shaped eye

34
Q

Papilledema

A

Swelling or inflammation of optic Nerve at the rear of the eye
Patients experience headaches, vomiting, vision loss or fraying vision

35
Q

Retinal Detachement

A

Separation of inner layers of retina from underlying membrane
Often seen in sports injuries, especially boxing

36
Q

Ear

A

Hearing, Balance, and orientation

37
Q

External Ear

A

Pinna, external auditory canal, and exterior portion of tympanic membrane (eardrum)

38
Q

Middle Ear

A

Inner portion of ear drum and ossicles

39
Q

Inner Ear

A

Cochlea and semicircular canals

40
Q

Process of hearing

A

Sound enters through pinna and travel through external auditory canal to the ear drum.
Vibrations against eardrum set up vibrations in the three small bones on inner side of tympanic membrane (malleus, incus, stapes).
Vibrations transmitted to cochlear duct at oval window
Movmenent of oval window causes fluid within cochlea to vibrate
Then hair movements that form nerve impulses that travel to the brain via auditory nerve.
Brain decodes these impulses and converts them to sound

41
Q

Foreign Body of Ear

A

Do not remove, just stabilize

42
Q

Creumen

A

Yellwish oily substance found inside ear canal “ear wax”

43
Q

Labyrinthitis

A

Feeling of vertigo or loss of balance after an ear infection
Irritation and swelling of inner ear affects Nerves of ear causing loss of balance
Management- antihistamine to reduce swelling, Valium for sedative or muscle relaxant

44
Q

Meniere Disease

A

Inner ear disorder when endolymphatic rupture causes increased pressure in cochlear duct.
Patients experience tinnitus and vertigo

45
Q

Oitis

A

Infection from bacterial growth within ear

46
Q

Perforate Tympanic Membrane

A

Ruptured eardrum from blast, foreign Body, infection

Consider pain management
