now i see what you mean about your experience with american nursing. doing a full head to toe assessment on a person with a sore finger does seem greatly excessive. in the u.s. each state has its own nurse practice acts, but they are all quite similar. all american nurses are expected to use a carefully spelled out nursing process & are required to show competency by delivering the same quality nursing care as any other nurse would usually & ordinarily provide in similar settings. failer to do so, can result in a nurse becoming unemployable, losing her license, & even being sued for negligence or malpractice. there is an underlying current of stress that may make some nurses overzealous, but hopefully, that is not all bad.
your suggested reading materials are excellent. i agree that anyone leaving the safety of their own homeland, needs to make a study of the area & the people where they intent to go. the u.s. government issues travel advisories intended to keep its citizens as safe as possible when they travel abroad.
