SECTION 1: GAS PHARYNGITIS DIAGNOSIS & CLINICAL PRESENTATION
Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 7-year-old boy is brought to your clinic by his mother with a 2-day history of
sore throat and fever to 101.8°F. On examination, his tonsils are enlarged and
erythematous with patchy exudates, and his anterior cervical lymph nodes are
tender and enlarged. His mother mentions that 3 of his classmates were
recently diagnosed with strep throat. A rapid strep antigen test is performed
,2
and returns positive. Based on the Centor/McIsaac criteria, which additional
finding would have further increased his pretest probability for GAS
pharyngitis?
A. He is 7 years old, which places him in the intermediate age group for GAS
B. He has a cough that has been present since yesterday
C. He has a history of seasonal allergic rhinitis with clear nasal discharge
D. He has no history of prior GAS infection in the past year
A. ✓ CORRECT
Correct Answer: A
Rationale: The modified Centor/McIsaac criteria award points for age 3-14
years, which increases the pretest probability for GAS pharyngitis in this 7-
year-old patient. A cough argues against GAS, as GAS typically presents with a
sore throat and absence of cough. Allergic rhinitis with clear discharge suggests
a viral upper respiratory process rather than bacterial pharyngitis. Prior GAS
infection history is not a component of the Centor/McIsaac scoring system.
Question 2 of 50
A 5-year-old girl presents with sudden-onset severe sore throat, fever to
103.2°F, and a sandpaper-like rash across her trunk and extremities. Her
mother reports she had a mild runny nose 2 days ago but it resolved. On
physical exam, her pharynx is beefy red with palatal petechiae, and the rash
blanches with pressure. Her rapid strep test is positive. Which clinical
syndrome is she most likely demonstrating?
A. Viral exanthem with secondary bacterial colonization
B. Scarlet fever associated with GAS pharyngitis
,3
C. Kawasaki disease in the acute phase
D. Fifth disease (parvovirus B19) with coincidental pharyngitis
B. ✓ CORRECT
Correct Answer: B
Rationale: The combination of acute pharyngitis with fever, palatal petechiae,
and a sandpaper-textured blanching rash is classic for scarlet fever, which is
caused by erythrogenic toxin-producing strains of Group A Streptococcus. Viral
exanthems typically do not produce this specific sandpaper quality and are not
associated with palatal petechiae. Kawasaki disease requires 5 days of fever
plus additional criteria including conjunctivitis and extremity changes, which
are absent here. Fifth disease presents with a slapped-cheek rash and lacy
reticular pattern, not a sandpaper truncal rash.
Question 3 of 50
A 9-year-old boy is brought to urgent care with sore throat and fever. His
mother is concerned because he has been refusing to eat and complains of
severe throat pain. On exam, you note significant tonsillar swelling with a
unilateral peritonsillar bulge that displaces the uvula to the contralateral side.
His voice is muffled, and he is drooling slightly. Which complication of GAS
pharyngitis has most likely developed?
A. Acute rheumatic fever
B. Retropharyngeal abscess
C. Peritonsillar abscess (quinsy)
D. Acute glomerulonephritis
C. ✓ CORRECT
, 4
Correct Answer: C
Rationale: The triad of unilateral tonsillar bulging, uvular deviation, and
muffled "hot potato" voice with drooling is pathognomonic for peritonsillar
abscess, a complication of untreated or severe GAS pharyngitis.
Retropharyngeal abscess typically presents with neck stiffness and dysphagia
without uvular deviation. Acute rheumatic fever and glomerulonephritis are
post-streptococcal sequelae that do not present with localized suppurative
findings.
Question 4 of 50
A 6-year-old girl presents with sore throat, fever to 100.4°F, and mild anterior
cervical lymphadenopathy. Her mother reports she has had a cough and runny
nose for 3 days. On exam, her tonsils are mildly erythematous without
exudates, and she has conjunctival injection. A rapid strep test is performed
and is negative. Which clinical features most strongly support a viral etiology
rather than GAS?
A. The presence of anterior cervical lymphadenopathy
B. The low-grade fever and absence of tonsillar exudates
C. The concurrent cough, rhinorrhea, and conjunctivitis
D. The negative rapid strep test alone
C. ✓ CORRECT
Correct Answer: C
Rationale: The combination of cough, rhinorrhea, and conjunctivitis constitutes
the classic viral syndrome presentation that argues against GAS pharyngitis, as
GAS typically causes an isolated sore throat without these viral
