,A 59-year-old male with a history of emphysema complains of an acute worsening of his
dyspnea and pleuritic chest pain following a forceful cough. Your assessment reveals that
he has a barrel-shaped chest, unilaterally diminished breath sounds, and tachycardia.

Select one:
A. Spontaneous pneumothorax
B. Exacerbation of his COPD
C. Acute pulmonary embolism

A. Generalized weakness
B. A rapid heart rate
C. Syncope or dizziness
D. Heart rate less than 60 beats/min

How does CPAP improve oxygenation and ventilation in patients with certain respiratory
problems?
, Select one:
A. It pushes thick, infected pulmonary secretions into isolated areas of the lung.
B. It prevents alveolar collapse by pushing air into the lungs during inhalation.
C. It forces the alveoli open and pushes oxygen across the alveolar membrane.
D. It decreases intrathoracic pressure, which allows more room for lung expansion.
C. It forces the alveoli open and pushes oxygen across the alveolar
membrane.
You and your partner arrive at the scene of a middle-aged man who collapsed about 5

C. immediately apply the AED pads and analyze his cardiac rhythm.
D. begin high-quality CPR and apply the AED as soon as possible.
