During a training session, a client suddenly feels pain radiating down the left shoulder and arm, up the neck, and around the back, accompanied by excessive sweating and difficulty in breathing. Which of the following precautions should the ACE certified Personal Trainer take?
- Have the client sit and rest for five minutes, and then take the client's blood pressure.
- initiate CPR because the client is clearly having a heart attack.
- Have the client stop all activity and contact EMS.
- Remove any shoulder and arm exercises to rule out nerve impingement.
