Exam 1 Flashcards
Rhino sinusitis most often caused by…
VIRUS
Think bacterial rhino sinusitis when..
- Symptoms >10 days w/o improvement
- Severe symptoms (fever >102, facial pain lasting longer than 3 days, purulent nasal drainage)
- Symptoms got better and then worse again
Rhinosinusitis treatment VIRAL
OTC analgesics, intranasal steroids (budesonide, flucticasone (flonase, nasacort, nasonex), decongestants sometimes (no longer than 3 days)
Rhinosinusitis treatment Bacterial
- amoxicillin or amoxicillin-clavulante (Augmentin is better, generally for pts with risk factors for resistance, give if pt looks sick – region with resistance, antibiotic use in past month, hospitalization in last 5 days, immunocompromise, comorbidities, severe infection-temp >102)
- (Penicillin allergic) Doxycycline (not in pregnancy) OR 3rd generation cephalosporin (cefixime, cefpodoxime) with or without clindamycin. OR respiratory fluoroquinolone (last line d/t side effects-prolonged QT, not in pregnancy) (levofloxacin, moxifloxacin)
Pharyngitis/tonsillitis most often caused by….
VIRAL
pharyngitis/tonsillitis when caused by bacteria think…
group A streptococcus
pharyngitis/tonsillitis can also be caused by….
Group C&G Strep, STI, diptheriae, EBV, Cytomegalovirus, Herpes simplex
Center scoring for rapid strep test…
Criteria Absence of cough: +1 Swollen, tender anterior lymph nodes: +1 Temp> 100.4 +1 Age 3-14 +1 15-44 0 45 or older -1
Score
1-2 no further testing or antibiotics
3-4 rapid strep test and treat
5 consider empiric treatment
Other diagnostics to order for pharyngitis/tonsillitis
throat culture (for high risk, DO NOT empirically treat before results are obtained), Monospot (false negative if tested within 7 days of symptom onset)-could do CMP (liver enzyme elevation with mono), CBC (lymphocytosis and atypical lymphocytes), cytomegalovirus will not show up on monospot, EBV & CMV serology testing may be used if repeat monospot is negative

Acute bronchitis cause
Most often caused by VIRUS, rarely bacteria, usually fall and winter.
Influenza A & B, parainfluenza, and RSV most common, less common coronavirus, adenovirus, rhinovirus, and metapneumovirus
H. influenza and strep pneumoniae
Chronic bronchitis should be considered when…
Chronic bronchitis should be considered only for pts who have had cough and sputum production on most days of the month for at least 3 months of the year during 2 consecutive years.
Acute bronchitis treatment
Smoking cessation. Humidification, rest, fluids
Bronchodilators x 7 days, Beta-adrenergic bronchodilators could be used in patients with acute bronchitis and wheezing associated with cough
Cough suppressants (dextromethorphan cough preparation every 4 hours, benzonatate, codeine, or hydrocodone if cough is severe)
Oral steroids x 5 days
Acute bronchitis treatment for influenza
Influenza is most common pathogen in acute bronchitis therefore if influenza is suspected or confirmed, antivirals medications such as oseltamivir, zanamivir may be effective within 48 hours of illness onset
Acute bronchitis treatment if pertussis is suspected
Antibiotic therapy if pertussis is suspected, pertussis is gram-negative bacterium. Suspicion of pertussis should be limited to individuals with a high probability of exposure, such as in community outbreaks. Pts w/ confirmed or probable pertussis should receive antibiotic therapy and be isolated for 5 days from the start of treatment. Macrolides are first line-azithromycin, erythromycin, clarithromycin. Second line therapy is trimethoprim sulfamethoxazole (Bactrim). Erythromycin has been the drug of choice. Azithromycin can cause QT prolongation and shouldn’t be used in those with CVD.
Asthma S/S
symptoms are variable and intermittent, wheezing, dyspnea, coughing, prolonged expiration due to air trapping (they won’t sound like they are exhaling, you won’t hear anything, you’ll hear a big breath in, a short breath out and nothing else), may be worse at night and cause pt to awaken
Asthma Diagnosis
FEV1/FVC <80% AND reversal of obstruction after bronchodilator administration
FVC
Forced Vital Capacity (FVC) shows the amount of air a person can forcefully and quickly exhale after taking a deep breath
FEV1
Forced expiratory volume is measured during the forced vital capacity test, the forced expiratory volume (FEV1) in one second measurement shows the amount of air a person can fully exhale in one second of the FVC test.
