NU 674 EXAM 1 questions and answers 2026\2027 A+
Grade
a set of goals and objectives with 10 year targets designed to guide national health promotion and
disease prevention efforts to improve the health of all people in the US
- correct answer healthy people 2020
prevents the onset of disease/condition; e.g. vaccinations/seatbelts
- correct answer primary prevention
identifies and treats asymptomatic people; e.g. screenings and identifying risk factors
- correct answer secondary prevention
care of established disease and preventing complications
- correct answer tertiary prevention
community wide approaches to prevent or reduce several diseases and conditions
- correct answer HI-5
"EEE" sounds like "AHH" on auscultation; sound is distorted due to no O2 perfusion; consider
pneumonia
- correct answer egophony
beats have weaker amplitude with respiratory inspiration, stronger with expiration; think COPD, asthma,
or pericardial disease
- correct answer pulsus paradoxus
typically viral, but can be caused by bacteria such as bordatella pertussis, H. influenza, S. pneumoniae
- correct answer 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
- correct answer bronchitis
characterized by purulent nasal excretion, post-nasal drip, sinus tenderness, cervical lymphadenopathy,
wheezes, rales, rhonchi, tahcypnea, injected pharynx, and tachycardia
- correct answer 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
- correct answer bronchitis
treated with amoxicillin 500mg q8h OR bactrim BID
- correct answer bronchitis
complications include MI, CHF of new onset up to 1 year after pt is hospitalized, arrhythmias, and death
- correct answer 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
- correct answer 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
- correct answer pneumonia
select empiric abx regimen that targets both typical pathogens and atypical pathogens
- correct answer pneumonia
