Answer to Question 1

ANS: B
A constant high-frequency, low-amplitude electrical current is passed between the two elec-trodes, and the return voltage is used to calculate the impedance.

Answer to Question 2

ANS: C
Recent evidence suggests that bradycardia and upper airway obstruction might cause apnea mon-itors to fail to signal apnea.
