| Verified Examination Questions and
Answers with Correct Answers
• primary prevention -✓✓prevents the onset of disease/condition; e.g.
vaccinations/seatbelts
• secondary prevention -✓✓identifies and treats asymptomatic people; e.g.
screenings and identifying risk factors
• tertiary prevention -✓✓care of established disease and preventing complications
• HI-5 -✓✓community wide approaches to prevent or reduce several diseases and
conditions
• egophony -✓✓"EEE" sounds like "AHH" on auscultation; sound is distorted due
to no O2 perfusion; consider pneumonia
• pulsus paradoxus -✓✓beats have weaker amplitude with respiratory inspiration,
stronger with expiration; think COPD, asthma, or pericardial disease
• bronchitis -✓✓typically viral, but can be caused by bacteria such as bordatella
pertussis, H. influenza, S. pneumoniae
• bronchitis -✓✓sudden onset in 12-24 hours without evidence of COPD,
pneumonia, or asthma; cough is initially dry but then turns productive and is worse
at night; afebrile or low grade temp; malaise, HA, chest burning/tightness,
dyspnea, wheezing
, • bronchitis -✓✓characterized by purulent nasal excretion, post-nasal drip, sinus
tenderness, cervical lymphadenopathy, wheezes, rales, rhonchi, tahcypnea, injected
pharynx, and tachycardia
• bronchitis -✓✓treatment methods include rest, fluids, room humidification,
inhaler if bronchospasms present, abx if specific organism identified, NOT
mucolytics or antihistamines b/c they dry out airways and exacerbate symptoms
• bronchitis -✓✓treated with amoxicillin 500mg q8h OR bactrim BID
• pneumonia -✓✓complications include MI, CHF of new onset up to 1 year after pt
is hospitalized, arrhythmias, and death
• pneumonia -✓✓CXR is most definitive diagnosis; sputum culture and sensitivity
with gram stain tells you exactly what abx to prescribe; begin abx presumptively to
decrease morbidity and can change regimen if needed
• pneumonia -✓✓urine tested to detect pneumococcal or legionella antigen;
elevated PCT level indicates likely bacterial etiology; CRP elevation while treating
can indicate worsening or tx failure; PSI and CURB65 used to identify who needs
hospitalization
• pneumonia -✓✓select empiric abx regimen that targets both typical pathogens
and atypical pathogens
• pneumonia -✓✓for patients without comorbidities and abx use, treat with
azithromycin, clarithromycin, doxycycline, amoxicillin-clavulonate, or
cefpodoxime PLUS macrolide, or fluoroquinolone monotherapy for 5-7 days
