aggressive cleaning, Allergies/skin conditions
Causative organisms for otitis externa: - ANS-Psuedomonas aeruginosa (20-60%);
Staphylococcus Aureus (10-70%); 10% fungal infection
Symptoms of otitis externa: - ANS-Discharge from ear, recent history of swimming or
placing something in the ear, low-grade fever, pain with movement of tragus, decreased
hearing, redness around ear
Objective findings of otitis externa: - ANS-Otalgia ( inner or outer ear pain), discharge,
fullness, itching, pain with movement of tragus, redness around ear, decreased hearing.
Treatment of pain and therapeutic management of otitis externa: - ANS-Warm
compresses, Auralgan, prednisone, Tylenol/ibuprofen, Wick (abx applied to wick )
When to wick with otitis externa: - ANS-If lumen is reduced to >50%, wicks can help
ensure delivery of topical abx to medial canal.
Treatment of otitis externa: - ANS-Topical fluroquinolones (Ciprofloxacin, Ofloxacin),
ibuprofen and apap for pain, neomycin/polymixin b/hydrocortison otic (antibiotic/steroid)
Hallmark sign of otitis externa: - ANS-Traction of pinna elicits pain
,When do we begin hearing tests in clinic for children - ANS-4 years old
What is a normal audiology test result and how are results read - ANS-Normal -10 to
+15 The higher the number, the greater the loss, Severe loss 71-90 (learning disability,
limited vocabulary), Profound loss 90
Risk factors related to elevated cholesterol - ANS-Obesity, Diabetes, Hypertension,
Family history: Coronary heart disease prior to age 55, Hyperlipidemia, Diabetes
Clinical findings for tetralogy of Fallot: - ANS-Cyanosis: caused by blood low in oxygen,
Shortness of breath and rapid breathing, especially during feeding or exercise, Loss of
consciousness, Clubbing of fingers and toes, Poor weight gain, delayed growth,
Polycythemia, metabolic acidosis, Systolic murmur at 2nd left ICS & holosystolic
murmur at LLSB
What criteria would you have to consider inpatient admission in a patient with
pneumonia - ANS-Infants less than 4 months old, Infant with poor feeding, grunting, O2
saturation <92%, respiratory rate >70 , Older child with grunting, inability to tolerate oral
intake, oxygen saturation ≤ 92 percent, respiratory rate > 50 breaths per minute, Any
age: Comorbidities (e.g., chronic lung disease, asthma, unrepaired or incompletely
repaired congenital heart disease, diabetes mellitus, neuromuscular disease)
Visual acuity of a 2-month-old - ANS-• Vision is 20/400 • Fix and follow objects
Viral conjunctivitis etiology (causative agent): - ANS-Adenovirus is the most common
cause. Other causes: HSV, herpes zoster, and varicella
Viral conjunctivitis symptoms: - ANS-o Watery discharge (profuse and clear), foreign
body sensation, redness o URI symptoms are common including sore throat and fever o
Itchy conjunctiva and swollen eye lids o Often bilateral
Viral conjunctivitis Clinical findings - ANS-o Normal visual acuity, PERRLA, EOMI,
Fundus normal o Mucoid-profuse watery discharge o Mild, diffuse injection and itching o
*Preauricular lymphadenopathy
Viral conjunctivitis Treatment: - ANS-Symptomatic Only - Warm or cool compresses,
Strict hand hygiene
Pharyngitis - ANS-Typically viral
Causative organism for bacterial pharyngitis - ANS-Group A Beta Hemolytic strep
Subjective findings for strep pharyngitis: - ANS-Rapid onset of sore throat, abdominal
pain, headache, dysphasiay
, Objective findings for strep pharyngitis: - ANS-Fever >103, Swollen glands, anorexia,
lack of uri s/sx, irritability, Exudative tonsils, scarlatina rash, strawberry tongue, anterior
cervical lymphadenopathy
Treatment for strep pharyngitis - ANS-Amoxicillin 5mg/kg/day x10 days
If allergy to first line tx for strep pharyngitis, what do you prescribe? - ANS-
Cephalosporin or macrolide (azithromycin)
Therapeutic tx for strep pharyngitis (in addition to abx) - ANS-Warm water
gargle/apap/ibu
Education re strep pharyngitis: - ANS-Discard toothbrush after 24hs on an abx and after
treatment completion
When may pt return to school with strep pharyngitis: - ANS-This is contagious. May
return to school after 24 hours on abx
Scarlet fever: - ANS-Occurs secondary to strep throat and progresses to acute
rheumatic fever if no intervention
Is scarlet fever common or rare? - ANS-Rare
Subjective/Objective findings of scarlet fever: - ANS-Scarlatina begins on face and
spreads down and out/strawberry tongue/Fever/pharyngitis
Treatment of scarlet fever: - ANS-amoxicillin 50-80 mg/kg/day x7 days
Classic triad of mononucleosis Pharyngitis: - ANS-Fever, equative pharyngitis
POSTERIOR cervical lymphadenopathy
Subjective sx of mononucleosis: - ANS-malaise, fatigue, headache, anorexia,
