Answer to Question 1

ANS: B
Inverted T waves suggest ischemia of the heart muscle, and abnormal configuration of the T wave occurs with electrolyte abnormalities such as hyperkalemia.

Answer to Question 2

ANS: C
Because this represents a potentially life-threatening arrhythmia, abnormal ST segments must be identified as soon as possible.
