Answer to Question 1

D
Feedback:
Inhalants can harm the brain, liver, heart, kidneys, and lungs, and abuse of any drug during adolescence may interfere with brain development. Dependence has not been definitively demonstrated, and hyperactivity is not a risk.

Answer to Question 2

D
Feedback:
Potassium channel blockers such as amiodarone prolong duration of the action potential, slow repolarization, and prolong the refractory period in both the atria and ventricles. Amiodarone blocks the effects of the sympathetic nervous system instead of stimulating it. Amiodarone and the other potassium channel blockers do not directly decrease automaticity.
