True regarding the treatment of acute rhinosinusitis
- A.
  
  Azithromycin is recommended as an option for first-line treatment
- B.
  
  Doxycycline or a respiratory fluoroquinolone should be instituted in most uncomplicated cases

  Fidaxomicin is now indicated as a primary treatment option
- D.
  
  Antibiotic use is frequently ineffective, given that most cases are viral
Correct Answer
D. Antibiotic use is frequently ineffective, given that most cases are viral

Explanation
Watchful waiting is encouraged in uncomplicated cases.

Macrolides (eg, azithromycin, fidaxomicin) are not recommended because resistance in Streptococcus pneumoniae.

First-line therapy is typically amoxicillin or amoxicillin/clavulanate. However, 90%-98% of rhinosinusitis cases are viral, meaning that antibiotics are not effective. Even in cases when the causative agent is bacterial, antibiotics may not be helpful.

Correct Answer
C. Suspicion of pneumonia is the primary indication to initiate antibiotic treatment

D. Educate patients that symptoms may last as long as 2 weeks and do not initiate antibiotics

Explanation
Antibiotics are ineffective in treating the common cold.

NSAIDs may be given for symptomatic relief.

Although antihistamines, nasal saline irrigation, opioids, and intranasal steroids have been used, evidence to support their use is lacking.

Change in nasal discharge color is not an indication for antibiotic treatment.

True regarding the treatment of streptococcal pharyngitis
- A.
  
  First-line treatment includes azithromycin and clindamycin
- B.
  
  Initiation of antibiotic treatment prior to the results of a rapid antigen detection test is recommended in symptomatic patients
- C.
  
  Penicillin V remains a first-line therapy due to its reliable antibiotic activity against group A beta-hemolytic streptococcal (GAS) infection
- D.
  
  Severe, persistent sore throat alone is an indication for antibiotic therapy
Correct Answer
C. Penicillin V remains a first-line therapy due to its reliable antibiotic activity against group A beta-hemolytic streptococcal (GAS) infection

Explanation
Do not administer antibiotics until rapid antigen detection test findings confirm diagnosis of GAS infection.

Amoxicillin and penicillin V are first-line treatments thanks to their reliable antibiotic activity against GAS infection.

Resistance to clindamycin and azithromycin has increased.

Antibiotics are usually unnecessary, even in those with sore throats; reassure patients that symptomatic treatment is usually sufficient, and symptoms usually last less than 1 week.
