I think Florence would have been greatly disheartened in the pandemic. In this day and age, statistics and evidence didn't make a whole lot of difference. Mixed messages and conflicting data coming from so many different 'experts' made it impossible to know exactly what was correct. Add in greed of those in the upper echelons, and I still believe some of the nonsense would have happened, like lack/shortages of PPE. Sadly, Florence wouldn't have stood a chance.
Also, in Florence's day, nurses were unmarried, no other obligations, and dedicated their time to the patients without much in the way of breaks, time off, or compensation. Nurses wore many hats as well, like housekeeping, cooking and serving, all of which she felt was in the nurses scope of duties.
