Q

Which is not a causative organism of acute otitis media (OM)?

a) S. aureus
b) S. pneumoniae
c) H. influenzae
d) M. catarrhalis

A

Answer: a) S. aureus

The other three organisms are common causes of OM (they are also common causes of sinusitis so this bacteria can come from the pharynx and invade the tissue of the middle ear thus producing OM)

Q

Which of the following are consistent with otitis media (choose all that apply):

a) bulging tympanic membrane
b) decreased movement of eardrum
c) fever
d) more visible landmarks
e) pain worsens with auricle manipulation

A

Answer: a,b,c

In OM: there is fever, ear pain, bulging tympanic membrane, decreased movement of the eardrum, less visible landmarks on the tympanic membrane, and dilated vessels within the ear

Note: auricle manipulation lessens the pain in OM but will worsen pain in acute otitis externa

Q

A patient presents with facial pressure, purulent nasal discharge, and ear pressure. The patient states they were sick with a cold for approximately 7-10 days, but have started feeling even worse than before. What is a likely diagnosis?

A

Acute bacterial rhinosinusitis

Viral rhinosinusitis (a cold) typically precedes ABRS. ABRS symptoms which differ include (purulent nasal discharge, fever, maxillary tenderness/pain, etc). Additionally the symptoms lasting beyond the 7-10 day period are suggestive of ABRS.

39
Q

Which organism is not a common cause of bacterial sinusitis?

a) S. pneumoniae
b) H. influenzae
c) M. catarrhalis
d) S. pyogenes

A

Answer: d) S. pyogenes

S. pyogenes is more responsible for pharyngitis & strep throat

The other organisms listed are commonly seen in bacterial sinusitis as well as acute otitis media

40
Q

True or false, sinusitis is typically diagnosed with clinical symptoms?

A

True.

CT scans are only done before surgery due to the inability to differentiate between bacterial and virus sinusitis. Transillumination has limited use. Culture and sensitivity should be done for resistant infections.

41
Q

Treatment for viral sinusitis is typically:

a) supportive
b) antibiotics
c) oral steroids
d) intranasal steroids and topical decongestants

A

Answer: a) supportive

42
Q

First line treatment for bacterial sinusitis is typically:

a) amoxicillin-clavulanate
b) levofloxacin
c) cefixime
d) azithromycin

A

Answer: a) amoxicillin-clavulanate

43
Q

If your patient has bacterial sinusitis, but has a PCN allergy, you could prescribe which antibiotic (choose all that apply)?

a) doxycycline
b) levofloxacin
c) cefixime
d) azithromycin

A

Answer: a & b

Appropriate alternatives are doxycyline, levofloxacin, moxifloxacin

Cefixime (3rd gen Cephalosporin) should be avoided due to concerns of cross-reactivity in patients with a PCN allergy

Macrolides (azithromycin) should be avoided due to high rates of resistance

44
Q

True or false, montelukast (Singular) is a leuktriene modifier with a risk of mental health side effects in children.

A

True. These SE can include: agitation, depression, sleeping problems, and suicidal thoughts and actions.

45
Q

True or false, nasal and oral corticosteroids are NOT helpful in acute bacterial rhinosinusitis?

A

True.

46
Q

True or false, HPI is better in diagnosing acute bacterial rhinosinusitis (ABRS) than physical exam?

A

True. History paints a better picture especially if the patient complains of symptoms persisting beyond 7-10 days, or of the patient is likely experiencing double sickening.

Symptoms of ABRS can be consistent with several diagnoses, again this reiterates the value in HPI.

47
Q

True or false, the most common causative organism for both ABRS and AOM is S. pneumoniae?

A

True.

48
Q

52
Q

Treatment for posterior epistaxis includes:

a) pressure for 5-20 minutes
b) ice
c) tilting the head forward
d) referral

A

Answer: d) referral

Posterior epistaxis patients need to be referred.

53
Q

True or false, most episodes of pharyngitis are viral.

A

True

54
Q

The most common causative organism for bacterial pharyngitis is:

a) Strep pyogenes
b) Strep pneumoniae
c) Haemophilus
d) Moraxella

A

Answer: a) Strep pyogenes

Strep pyogenes is a Group A beta-hemolytic streptococcus

Note: GABHS does not produce beta-lactamase which is why they are susceptible (can be treated with) penicillin

55
Q

True or false, common causative organisms for acute otitis media and bacterial sinusitis such as moraxella catarrhalis and haemophilus influenzae produce beta-lactamase which is why they are resistant to PCN treatment?

A

True.

Note that the organism responsible for strep throat (strep pyogenes) does not produce beta-lactamase which is why penicillin is a treatment option for the diagnosis of strep throat.

In order to use amoxicillin-clavulanate as the primary treatment for AOM and bacterial sinusitis it requires the addition of the “clavulanate.”

56
Q

What is the “CENTOR” criteria?

A

It is the criteria used to guide strep treatment and testing.

Cough (-1 point if cough present; +1 point if cough absent)
Exudates +1 point
Nodes +1 point
Temperature 100.4+ (38 Celsius) +1 point
OR age <15=+1 point and age >45=-1 point

1 point total= strep unlikely so don’t treat
2=test for strep (if negative rapid in kids, do a culture)
3-4=treat for strep empirically

57
Q

True or false, GABHS pharyngitis always requires treatment.

A

False. It is self-limited usually.

Treatment is done to avoid complications (rheumatic fever ,glomerular nephritis, abscesses), to shorten duration, reduce communicability, provide acute relief

58
Q

Children can return to school within how many hours after treatment has been initiated for strep throat (GABHS)?

A

24 hours

59
Q

First line treatment for GABHS pharyngitis includes:

a) PenVeeK orally for 10 days
b) amoxicillin orally for 10 days
c) amoxicillin-clavulanate orally for 10 days
d) Penicillin G benzathine IM once

A

Answer: a & b

Primary treatment choices are oral PenVeeK and amoxicillin.

Amoxicilin-clavulanate is not needed because GABHS doesn’t produce beta-lactamase (so it doesn’t render PCN ineffective)

While Penicillin G IM is appropriate as first line (it should be reserved for patients where noncompliance is a concern)

60
Q

Second-line treatment options for GABHS pharyngitis include:

a) cephalexin
b) cefadroxil
c) TMP-SMZ
d) doxycycline

A

Answer: a& b
