Extraneous variables add error to an experiment and influence the outcome of an experiment due to external influences (Kaya, 2015). Therefore, one of the research goal is to decrease and control the influence of extraneous variables. The extraneous variable are Advanced Registered Nurse Practitioners Cardiology-ARNPs and Physicians Cardiologist tiredness, employee motivation, and job satisfaction which could affect the outcome. Both ARNPs and Physicians will be using a standardizing method of interview to obtain information and review medical history information.

Eligible participants will be divided in two groups of 75 participants, which will be assigned as group A and B. A computer randomization program will generate Group A, which will be identified as patient currently on pharmacological intervention for cardiovascular diseases and Group B will be participant status post MI. A standardized one-on-one interview will be scheduled seven days after patient was discharged from the hospital. The potential research study participants must understand English fluently, pass initial interview, pass a psychiatric evaluation, and able to give a written informed consent. The computer will generate a report data, which will be analyzed by ARNP-cardiology leader as probability-based sampling; therefore, bias won’t be arising in sample
