ensure accurate readings.
8. What does pneumonia sound like in the lungs?
A) Clear breath sounds
B) Crackles and decreased breath sounds
C) Wheezing only
D) Pleural friction rub
Answer: B
Rationale: Pneumonia typically presents with crackles and
decreased breath sounds due to fluid and inflammation in the

9. What does asthma sound like in the lungs?
A) Clear breath sounds
B) Crackles
C) Wheezing
