A) have her create an anxiety hierarchy.
B) consult her family doctor to obtain a prescription for antianxiety medications.
C) clearly identify her specific behavioral problem and determine its baseline rate.
D) confront her irrational beliefs about bridges and push her toward the realization that her way of thinking is unhealthy and must be replaced with more constructive, rational thoughts.
