49
What do we want to prevent in ear infections?
Chronic ear infections
50
What is a huge concern in macular degeneration?
Safety
51
Does an ear infection have to be cleared up before surgery?
Yes
52
surgical treatments for otitis media
tympanocentesis, myringotomy
53
Tympanocentesis
drainage of fluid from the middle ear by using a small gauge needle to puncture the tympanic membrane
54
Myringotomy
tubes put in ears
55
what is the purpose of ear tubes
It is placed in the ear drum to allow for air to enter & keep middle ear healthy by preventing fluid from collecting in the middle ear
56
After getting ear tubes, ears should not get...
wet.
57
Sinusitis usually occurs after what?
a URI/flu
58
What causes your sinuses to become infected?
swelling of the sinuses block drainage openings & so the sinuses fill with fluid. Bacteria will start growing in the fluid & the sinuses will become infected and produce a foul smelling mucus.
59
How does bacteria spread to the sinus?
openings in the nasal turbinates
60
Sinusitis risk factors

63
orbital cellulitis/abscess
looks like a big welt on eye
64

what can cause a bloody nose?
picking nose, trauma, during respiratory illness, during strenuous exercise, in conjunctive with a systemic disease(hypertension, coagulation disorders), sinusitis, allergic rhinitis, substance abuse
68
What are some interventions for a bloody nose?
put pressure to anterior nasal septum, alleviate fear, choking sensation, apply ice for vasoconstriction, calm individual to stop crying which will reduce pressure in blood vessels & allow bleed to stop sooner
