Nurse

It is known that triage nurses frequently treat patients who seek medical attention first, making them the ones who are most likely to notice the early signs of a potential biological attack.

The mind provides assistance for this in the form of strong core education. Each nurse will have distinct talents, passions, and expertise because of the wide variety of specializations and complicated abilities required in the nursing practice.

Here's another question with an answer related to nurses:
