Answer to Question 1

ANS: B
The PaO2/FIO2 for answer A is 317, which shows no ALI or ARDS. The PaO2/FIO2 for answer B is 125; this is an indication for PEEP therapy (PaO2/FIO2 < 200 for ARDS). The compliance for answers C and D is 50 mL/cm H2O and 53 mL/cm H2O, respectively. These compliances are normal for intubated patients.

Answer to Question 2

ANS: B
Approximately 15 minutes after an increase in PEEP, all ventilatory and available hemodynamic parameters are measured and calculated.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
