Mari,

although I'm not sure about the Klonopin, i think it makes more sense to take it, and skip the others. here is my reasoning on the Klonopin:

1. in normal doses, it should not affect cardiorespiratory parameters.
2. anxiety due to missed Klonopin could affect your heart rate.

Verapamil and Aspirin both directly affect the cardiovascular system, so if they told you to skip them, then skip them.

good luck with the test! hope all is well!
