  a. 0.02 L/cm H2O
  b. 0.03 L/cm H2O
  c. 0.22 L/cm H2O
  d. 0.34 L/cm H2O

Answer to Question 1

ANS: C
The formula for calculating effective static compliance is Cs = VT/(Pplateau  EEP).

Answer to Question 2

ANS: C
Emphysema causes an increase in pulmonary compliance, whereas ARDS and kyphoscoliosis cause decreases in pulmonary compliance. Asthma attacks cause increase in airway resistance.

Over time, chronic hepatitis B virus and hepatitis C virus infections can progress to advanced liver disease, liver failure, and hepatocellular carcinoma. Unlike other forms, more than 80% of hepatitis C infections become chronic and lead to liver disease.
