Nurses are crucial at any medical institute or hospital. They can offer fundamental medical care to the sick, aid surgeons or doctors in their job, and show the tender, compassionate side of the health field. When they do so, patients feel comfortable in the hospital environment, regardless of the continuous prodding of hurting needles. Also, patients abide by doctors instructions more docilely, in spite of the prospect of further examination and scans to be carried out. Nurses are in great demand all over the world.
