A patient's baseline arterial blood gas (ABG) reveals a partial pressure of oxygen (PaO2) of 78 mm Hg while receiving 35 supplemental oxygen.
 
  What should the ventilator fractional inspired oxygen (FIO2) be set at to obtain a target PaO2 of 95 mm Hg?
  a. 0.34
  b. 0.43
  c. 0.55
  d. 0.67

Question 2

The mode of ventilation that provides pressure-limited, time-cycled breaths that use a set tidal volume as a feedback control is which of the following?
 
  a. Pressure support ventilation (PSV)
  b. Pressure-regulated volume control (PRVC)
  c. Pressure-controlled continuous mandatory ventilation (PC-CMV)
  d. Bilevel positive airway pressure (Bilevel PAP)

Answer to Question 1

ANS: B

Answer to Question 2

ANS: B
Pressure support ventilation (PSV) is pressure-limited and flow-cycled. Pressure regulated vol-ume control (PRVC) is a dual control mode of ventilation that provides the benefits of pressure breathing along with targeting a set volume. These breaths are pressure-limited, time-cycled, and use tidal volume as a feedback. The pressure is adjusted by the ventilator to meet the set volume. Pressure-controlled continuous mandatory ventilation (PC-CMV) is pressure-limited and time-cycled but does not have a volume feedback system. Bilevel PAP is similar to PC-CMV in that it is pressure-limited and time-cycled with no volume feedback.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
