SECTION 1: RESPIRATORY EMERGENCIES (Questions 1-40)
1. Which of the following best describes the primary mechanism producing wheezing
during an acute asthma exacerbation?
A) Loss of alveolar surfactant
B) Bronchospasm of the smooth muscle
C) Pulmonary embolism obstructing vessels
, D) Pleural friction rub
Answer: B) Bronchospasm of the smooth muscle
Rationale: Asthma wheezing results from reversible bronchoconstriction
(bronchospasm) of the airway smooth muscle, which narrows the lumen and creates
turbulent airflow.
2. In a patient with chronic obstructive pulmonary disease (COPD), which
component is most responsible for the increased residual volume?
A) Decreased airway resistance
B) Loss of elastic recoil of the lungs
C) Hyperinflation of the diaphragm
D) Increased surfactant production
Answer: B) Loss of elastic recoil of the lungs
Rationale: Emphysema, a form of COPD, destroys alveolar walls, reducing elastic
recoil and causing air trapping, which raises residual volume.
3. Which auscultatory finding is most characteristic of pulmonary edema due to
left-sided heart failure?
A) High-pitched inspiratory wheezes
B) Fine crackles (rales) at the lung bases
C) Bronchial breath sounds over the periphery
D) Expiratory stridor
Answer: B) Fine crackles (rales) at the lung bases
Rationale: Fluid transudation into alveolar spaces produces fine crackles
(rales) that are most prominent at the bases in left-sided failure.
,4. A 4-year-old child presents with a barking cough and inspiratory stridor that
worsens at night. Which viral infection is most likely?
A) Respiratory syncytial virus (RSV)
B) Influenza A
C) Parainfluenza virus
D) Adenovirus
Answer: C) Parainfluenza virus
Rationale: Parainfluenza virus is the classic cause of croup, which presents
with a "barking" cough and inspiratory stridor.
5. Which of the following is the most sensitive early sign of a spontaneous
pneumothorax on physical exam?
A) Tracheal deviation away from the affected side
B) Hyperresonance to percussion
C) Dullness to percussion
D) Jugular venous distention
Answer: B) Hyperresonance to percussion
Rationale: Hyperresonance over the affected hemithorax reflects air in the
pleural space and is an early, sensitive sign of pneumothorax.
6. A 45-year-old male with a history of COPD presents with severe respiratory
distress, audible stridor, and nasal flaring. He is sitting upright in the
tripod position and is unable to speak in full sentences. What is the
MOST appropriate initial action?
A) Administer a nebulized bronchodilator
, B) Apply a non-rebreather mask at 15 L/min
C) Prepare for immediate advanced airway management
D) Obtain a 12-lead ECG
Answer: C) Prepare for immediate advanced airway management
Rationale: Stridor indicates upper airway obstruction. The patient's inability
to speak in full sentences and tripod positioning suggest impending respiratory
failure. Immediate advanced airway management (e.g., RSI) is indicated.
7. Which of the following is the most common bacterial cause of community-
acquired pneumonia in adults?
A) Mycoplasma pneumoniae
B) Streptococcus pneumoniae
C) Haemophilus influenzae
D) Legionella pneumophila
Answer: B) Streptococcus pneumoniae
Rationale: Streptococcus pneumoniae is the most common bacterial cause of
community-acquired pneumonia in adults.
8. A patient with pneumonia presents with fever, productive cough, and pleuritic
chest pain. On auscultation, you hear bronchial breath sounds and crackles
over the right lower lobe. What is the most likely diagnosis?
A) Pulmonary embolism
B) Lobar pneumonia
C) Bronchitis
D) Asthma exacerbation
