Answer to Question 1

1,2
Rationale 1: One of the effects of beta1 agonists is to increase the heart rate.
Rationale 2: One of the effects of beta1 agonists is to increase force of cardiac contraction, which would be felt as a stronger pulse.
Rationale 3: Pupil dilation is an effect of alpha1 drugs.
Rationale 4: Beta1 antagonists are given to control dysrhythmias.
Rationale 5: Beta1 antagonists are given to control hypertension.

Global Rationale: The effects of beta1 agonists are to increase the heart rate and the force of cardiac contraction. Pupil dilation is an effect of alpha1 drugs. Beta1 antagonists are given to control dysrhythmias and hypertension.
