Principles And Clinical Application Of Inhaled Anesthetic Management Practice Tests

Question 1

How does a decrease in cardiac output affect the rate of rise of the alveolar partial pressure (FA/Fi) for a highly soluble inhaled anesthetic?

Accepted Answer

It increases the rate of rise of FA/Fi.

Answer

It decreases the rate of rise of FA/Fi.

Answer

It has no effect on the rate of rise of FA/Fi.

Answer

It causes the FA/Fi to reach equilibrium instantly.

Second Gas Effect

Answer

Concentration Effect

Answer

Diffusion Hypoxia

Answer

Solubility Effect

Question 3

Inhaled anesthetics with low blood-gas solubility coefficients exhibit a slower onset of action compared to those with high blood-gas solubility.

Accepted Answer

Halothane

Answer

Isoflurane
