• inferior vena cava compression
• sciatic nerve stretch injury
• lateral femoral cutaneous injury

Answer 1

• Cerebrovascular injury
• sciatic nerve stretch injury

Question 2

The preferred location of the fresh gas inlet is?

• between the pressure manometer and absorbent
• between the reservoir bag and the inspiratory valve
• between the Y-piece and the expiratory valve
• between the absorbent and the inspiratory valve

Answer 2

• between the absorbent and the inspiratory valve

Question 3

Which is most likely to occur with the degradation of sevoflurane by absorbent?

• Dessicated absorbent decreases degradation
• It is degraded more as the length of the anesthetic increases
• More degradation occurs with lower concentrations
• More degradation occurs at lower temperatures

Answer 3

• It is degraded more as the length of the anesthetic increases

• stretching of the brachial plexus

Answer 6

• stretching of the brachial plexus

Question 7

In the prone position, which pathophysiologic change occurs?
