Which of the following are beta1 effects of the epinephrine released during shock compensation?
  1. Increase in chronotropy (heart rate)
  2. Increase in inotropy (strength of muscular contractions)
  3. Increase in dromotropic rate (electrical pulses in the heart).
  4. Increase in peripheral vascular resistance
  5. A, B, and C
Explanation
Answer: A, B, and C- Epinephrine causes a variety of effects in the body, but the beta1 effects are primarily cardiac and include an increase in heart rate, strengthening of muscle contractions, and conduction speed of electrical impulses in the heart. 

Though epinephrine causes peripheral vascular resistance to increase and GI tract smooth muscle relaxation, these are beta 2 effects.
