Before surgery, the surgical procedure and postoperative care were discussed with Mr. Peterson and his wife. As part of this teaching, the Petersons were taught that coronary artery bypass graft (CABG) surgery was being done to:

a. cure coronary artery disease
b. reopen blocked coronary arteries
c. improve myocardial blood flow

c.improve myocardial blood flow

Explanation

The surgery improves myocardial blood flow bypassing coronary vessels that is blocked or narrowed, during surgery a part is cut or grafted from the internal mammary artery or radial artery and then attached to aorta and use to create a new connection tissues and pathway tissue perfusion is then established through this which is the ability of fluid or blood to flow again.

The surgery help to create passage of flow for blood in the myocardial

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

a chair, a bed, and a toothbrush
