Answer to Question 1

ANS: B
Most galvanic fuel cells use a gold anode and a lead cathode. Unlike the Clark electrode, current flow across these poles is generated by the chemical reaction itself. Thus, unless accessories such as alarms are included, a galvanic cell needs no external power. Unfortunately, this means that galvanic cells respond more slowly than do Clark electrodes, sometimes taking as long as 60 sec.

Answer to Question 2

ANS: C
Antiarrhythmic medications (such as lidocaine) may offer a temporary solution until the underly-ing cause can be identified and treated.
