Respiratory Assessment
Breath Sounds
1. Vesicular breath sounds are characterized by:
A) Loud, high-pitched sounds over the trachea
B) Soft, low-pitched sounds over lung periphery
C) Harsh sounds between the scapulae
D) Absent sounds in emphysema
Answer: B)
Rationale: Vesicular sounds are normal, soft sounds heard over most lung fields during
inspiration.
2. Bronchovesicular sounds are normally heard:
A) Over the trachea
B) Between the scapulae and 1st-2nd intercostal spaces
C) At the lung bases
D) Only in pneumothorax
Answer: B)
Rationale: These medium-pitched sounds occur where bronchi bifurcate near major airways.
3. Bronchial breath sounds indicate pathology when heard:
A) Over the manubrium
B) Over peripheral lung tissue
C) In the 5th intercostal space
D) During expiration only
Answer: B)
Rationale: Bronchial sounds in peripheral areas suggest consolidation (e.g., pneumonia).
Voice Sounds & Fremitus
4. Increased tactile fremitus suggests:
A) Pneumothorax
B) Pulmonary consolidation
C) Emphysema
D) Pleural effusion
,ESTUDYR
Answer: B)
Rationale: Dense tissue transmits vibrations better (e.g., pneumonia).
5. A patient says "99" during assessment. The sound is clearly heard through the stethoscope.
This is:
A) Normal bronchophony
B) Abnormal bronchophony
C) Egophony
D) Whispered pectoriloquy
Answer: B)
Rationale: Clear "99" indicates consolidation (should be muffled normally).
6. "Eeee" heard as "Aaaa" through the stethoscope is:
A) Bronchophony
B) Egophony
C) Normal fremitus
D) Pleural rub
Answer: B)
Rationale: Egophony suggests pleural effusion or consolidation.
Pathological Respiratory Patterns
7. Cheyne-Stokes respirations are characterized by:
A) Crescendo-decrescendo breathing with apnea
B) Rapid, shallow breaths
C) Irregular gasps with pauses
D) Prolonged expiration
Answer: A)
Rationale: Cyclic pattern seen in heart failure or brain injury.
8. Kussmaul respirations occur with:
A) Asthma
B) Metabolic acidosis (e.g., DKA)
C) Pulmonary embolism
D) Pneumothorax
Answer: B)
Rationale: Deep, rapid breathing compensates for acidosis.
9. Biot's respirations suggest:
A) Increased intracranial pressure
B) COPD exacerbation
C) Anxiety attack
, ESTUDYR
D) Pulmonary edema
Answer: A)
Rationale: Irregular clusters of breaths with apnea indicate brainstem damage.
Adventitious Lung Sounds
10. Coarse crackles are caused by:
A) Fluid in larger airways
B) Narrowed bronchioles
C) Pleural inflammation
D) Lung hyperinflation
Answer: A)
Rationale: Loud, bubbly sounds from secretions (e.g., pulmonary edema).
11. Wheezing indicates:
A) Airway narrowing (e.g., asthma, COPD)
B) Pleural friction
C) Lung consolidation
D) Pneumothorax
Answer: A)
Rationale: High-pitched whistling from bronchoconstriction or obstruction.
12. A pleural friction rub is:
A) Musical sounds on expiration
B) Grating sound synchronous with breathing
C) Absent breath sounds
D) Crackles that clear with coughing
Answer: B)
Rationale: Inflamed pleural surfaces rubbing together (e.g., pleurisy).
Clinical Application
13. Barrel chest (1:1 AP-to-lateral ratio) suggests:
A) Chronic hyperinflation (COPD)
B) Pneumothorax
C) Pulmonary fibrosis
D) Atelectasis
Answer: A)
Rationale: Increased AP diameter from air trapping.
