working as a nurse, there are many times when i have been worried about my patients. sometimes when a patient is just starting to get seriously ill, there are not any obvious signs, but my intuition is almost always correct.
those are very beneficial tools as well but sometimes experience plays a large part in patient outcomes.
i suppose, but research and concrete knowledge is more beneficial as it is a very hands on and physical occupation, especially when the health of others are in their hands.
