Chapter 11: Lungs and Respiratory System


1)

What is the normal respiratory rate for adults at rest?

A. 8-12 breaths per minute
B. 12-20 breaths per minute
C. 20-28 breaths per minute
D. 28-35 breaths per minute

Answer: B. 12-20 breaths per minute



Rationale: The normal respiratory rate for adults at rest is 12-20 breaths per minute. Rates below
12 (bradypnea) or above 20 (tachypnea) may indicate respiratory problems.




2)

Which breath sound is normal over the peripheral lung fields?

A. Bronchial
B. Bronchovesicular
C. Vesicular
D. Adventitious

Answer: C. Vesicular

, Rationale: Vesicular breath sounds are normal over the peripheral lung fields. They are soft, low-
pitched sounds heard during inspiration and early expiration.




3)

What does dullness to percussion over the lungs indicate?

A. Normal air-filled lungs
B. Fluid or consolidation
C. Hyperinflated lungs
D. Pneumothorax

Answer: B. Fluid or consolidation



Rationale: Dullness to percussion indicates the presence of fluid (pleural effusion) or
consolidation (pneumonia) in the lungs, as these dense materials do not resonate like air.




4)

Which adventitious breath sound is described as high-pitched, musical sounds?

A. Crackles
B. Wheezes
C. Rhonchi
D. Pleural friction rub

Answer: B. Wheezes



Rationale: Wheezes are high-pitched, musical sounds caused by air flowing through narrowed
airways, commonly heard in asthma or bronchospasm.
