Answer to Question 1

Ans:
B

Feedback:

The typical onset of pneumococcal pneumonia involves production of clear sputum, along with faint breath sounds and fine crackles. The patient is less likely to be hypotensive, have copious bloody sputum, or have chest pain. A lack of lung consolidation or sputum production is more closely associated with atypical pneumonias.

Answer to Question 2

Ans:
D

Feedback:

Negative intrapleural pressure holds the lungs in place against the chest wall and prevents their natural elastic properties from causing them to collapse. Intrapleural pressure is negative in relation to the inflated lung, and the chest wall exerts negative pressure on the lungs that keeps them from contracting and contributes to inspiration. Intrapulmonary pressure oscillates between positive and negative relative to atmospheric pressure with expiration and inspiration.
