Therefore, when a person is at rest, no effort is needed to breathe out. During vigorous exercise, however, a number of muscles participate in exhalation. The abdominal muscles are the most important of these. Abdominal muscles contract, raise abdominal pressure, and push a relaxed diaphragm against the lungs, causing air to be pushed out.
Another difference to consider when looking at a nurse practitioner vs physicians assistant career is the areas of specialization that are available. NPs can work in many different and diverse areas, such as geriatrics, mental health, pediatrics and womenâs health.
The difference between being a physician and being an advanced practice nurse is the approach. The medical model is more interested in fixing the medical problem. The nursing model is interested in helping the patient live the best life they can live. It's subtle, but important.
