Q

What is a hyphema?

A

bleeding into the anterior chamber (behind the cornea)

–is usually visible as a blood level in the eye

30
Q

Trauma to the eye increases the risk of developing all but which one of the following?

a) Strabismus
b) Glaucoma
c) Cataracts
d) Hyphema

A

a) Strabismus

  • -cataracts & glaucoma may develop years after eye trauma
  • -hyphemas, if they occur, develop soon after eye trauma and may reoccur
31
Q

Corneal abrasions can be managed with topical application of what?

A
  • -antibiotics to prevent infection (corneal abrasions are susceptible to infection)
  • -pain control can be obtained with topical or oral NSAIDs
32
Q

What is the greatest risk in a pt with a hyphema?

A

Rebleed! = greatest risk
–> often leads to more eye damage (vision loss) than the initial bleed

Secondary risks:
–> increased risk for development of glaucoma & cataracts following eye trauma (not specific to hyphemas)

33
Q

With hyphemas, where does the bleeding occur?

A

in anterior chamber

–not as susceptible to outside organisms like a corneal abrasion would be –> infection not as imminent a problem

34
Q

Intraocular pressure assesses for which eye condition?

A

glaucoma

35
Q

A 16yo was hit in the eye 1 day ago and now has ecchymoses on the upper and lower lids with 5 out of 10 eye pain. All but which of the following would be appropriate to obtain at this time?

a) Visual acuity
b) Intraocular pressure
c) CT scan
d) Fluorescein stain

A

b) Intraocular pressure
- -> this is used to test for glaucoma, which, if it occurs, would be years later

  • -almost all eye injuries should have a visual acuity done
  • -an eye injury can produce more than 1 injury
    • -> person with “black eye” could also have other injuries such as a corneal abrasion or orbital fracture
  • -CT scan would be appropriate to assess for an orbital fracture
  • -a fluorescein stain could be used to assess for a concurrent corneal abrasion
36
Q

An ear canal that is edematous with exudate describes which condition? What is one of most common organisms? Treatment?

A

otitis externa (OE)

  • -Pseudomonas, which is susceptible to fluoroquinolones
  • -tx w/ topical antibiotics, bc antibiotic needs to be in contact with the canal
    • -> oral antibiotics are not effective!
  • -can combine the topical antibiotics with a topical steroid
37
Q

What is one of the primary causes of OE? Management?

A

overhydration of the ear canal

  • -keep ear canal dry to enhance healing
  • -limit swimming during acute phase (earplugs don’t work!)
  • -equal parts alcohol and white vinegar used at the end of the swimming day can help evaporate remaining water droplets, and prevent swimmer’s ear
    • -> these drops can prevent, but are not effective tx for OE
38
Q

a) 2yo with cleft palate repair at 1 year of age
b) 15 month old w/Down syndrome

A
  • -typically appears as a pearly white opacity in the upper outer quadrant of the TM
  • -chronic serous OM is a risk factor
  • -immediate referral needed d/t risk of continued growth and potential spread into the brain
43
Q

How can you distinguish tympanosclerosis from a cholesteatoma?

A

tympanosclerosis (scar tissue) is also whitish appearing but more cloud-like in appearance and is usually seen in the lower quadrants of the TM
–> whereas cholesteatoma typically appears as a pearly white opacity in the upper outer quadrant of the TM

–pt w/tympanosclerosis usually has a hx of PE tubes or TM perforations

44

  • -pt usually has a hx of PE tubes, TM perforation, or ear injury
  • -topical antibiotics may be used, but also refer to ENT with initial perforation
45
Q

Child may have no sx!

  • -the child may appear to hear well bc the other ear may be compensating
  • -all hearing in the affected ear is not destroyed immediately
46
Q

If epistaxis does have an underlying medical cause, it is most often…? Signs?

d) Nasal neosynephrine ( = OTC nasal spray such as Afrin)

  • -indicated only for short-term use (3 days max) bc extended use leads to rebound chronic nasal congestion
  • -nasal steroid sprays such as beclomethasone, oral cetirizine, and montelukast are recommended tx for allergic rhinitis and can be used long-term
49
Q

What complication of sinusitis are adolescent males more prone to?

a) Intracranial abscess
b) Potts puffy tumor
c) Orbital cellulitis
d) Dental infection

A

a) Swimming/diving
b) Boxing/wrestling
c) Weight lifting
d) Cross-country running

A

a) Swimming/diving

  • -swimming and diving are known contributing factors to the development of sinusitis as well as exacerbating factors during tx
    • -> may be d/t contaminated water entering the nasal cavities and sinuses at an increased pressure
51
Q

All of the following may predispose a pt to thrush except:

a) Age
b) Steroid therapy
c) Antibiotics
d) Poor oral hygiene

A

d) Poor oral hygiene
- -> is risk factor for developing dental caries, not thrush

a) Fever and dehydration
b) Submandibular lymph nodes
c) Vesicular lesions on tonsils
d) Friable and edematous gingiva

A

c) Vesicular lesions on tonsils
- -> if lesions seen on the anterior pillars and/or tonsils, another dx should be considered

  • -with 1st exposure, child is usually quite ill
    • -> intraoral lesions occur in the front of the mouth
    • -> gingiva are typically painful, friable (bleed easily), and edematous (the swelling can be so severe as to nearly cover the teeth)
    • -> the lesions do to extend to the tonsils
    • -> fever is common and be fairly high (104F)
    • -> illness can cause anorexia d/t painful mouth lesions, leading to risk of dehydration
    • -> submandibular nodes drain the mouth and often become enlarged and tender with herpetic infections of the mouth and lips

a) Clindamycin
b) Erythromycin
c) Bactrim
d) Ceftriaxone

A

c) Bactrim

63
Q

Retropharyngeal abscess is typically seen in what age group and includes what mainstay tx?

A
  • -2 to 6 yr olds, with average age of 3
    • -> bc of changes in lymphatics, do not usually occur after age 6

A

cervical adenitis = swollen cervical node or nodes

  • -causes include strep pharyngitis, infectious mononucleosis, and to a lesser extent, TB
    • -> appropriate to test for those conditions if indicated

  • -orbital cellulitis can be life and vision threatening
69
Q

What can cause conductive hearing loss? How?

A
