Question

How does physics relate to nursing?

Answer 1

Hint: In nursing, physics plays a very important role. The knowledge of pressure (blood pressure in veins), viscosity, surface tension (capillary action), fluids in motion (blood circulation), diffusion (internal energy), vision (optics), sound (hearing) and many more physical phenomena is necessary in nursing.

Complete answer:
Nursing is a profession which requires the use of latest technology for the care and betterment of patients and individuals of all ages for prevention of diseases and illness.
The following are a few uses of physics in nursing:

The most common use of physics in nursing is to measure blood pressure of patients. The control of high blood pressure is mainly responsible for heart attacks and strokes.
The medical instrument for measurement of blood pressure is called a sphygmomanometer, it has three parts, a cuff that inflates when air is pumped, a pressure meter also called a manometer for measuring air pressure in the cuff and a stethoscope for hearing heart beats.

Another basic tool for monitoring and nursing a patient is related to X-ray. Without the help of X-ray, it would not be possible to inside the patient without surgery. X-ray is high energy electromagnetic radiation, which penetrates and gives the image of an object's insides.

The use of hypodermic needles in health care and nursing are available today because of the advancement of physics and science which enables nurses and doctors to administer medicine directly into the bloodstream.

Digital monitoring devices in all types of medical instruments use digital electronics.
The use of artificial respiration devices like ventilators (i.e. mechanical ventilation) or oxygen masks are necessary for patients with difficulties in breathing.

Thus, we see that without physics nursing and healthcare in the modern world would be a lot more difficult and inefficient.

Note:
Nursing uses the laws of physics and knowledge of physical phenomenon to deal with modern technology, electrical devices, digital life support systems, etc to give care to not only patients in hospitals but also in the military, nursing homes, and many more.
