All kidding aside those girls got a very advanced education for females in that era.
If one disregards all the household busy work, there is quite allot that is contained in many modern nursing programs. The "probation nurse" got her sciences (A&P, Chem, Bact, general Physics), nutrition,time management skills, Med Dose Calc, pharma, and so forth. The advice about observation is priceless and right on the money.
The emphasis on training of private duty practice was critical as hospitals made very tidy sums hiring out their nurses for "home care". If at all possible the very wealthy and or anyone else whom could afford it remained at home and had their care brought to them. One British king even had an entire surgery suite done up at one of the palaces so he could have his gall blader (or was it appendix?) removed and recover in the comfort of his own "home" as it were. Of course any one who is a fan of those BBC/PBS dramas knows an illness was serious when a "trained nurse" was engaged and arrived at the door steps of a town house or country estate. *LOL*
Now about that cracked ice and champange!
