There are some VERY good looking ICU nurses and I speak from direct knowledge.

Very good acting. However my wife is a nurse and makes 150K/YR working 3 days per week and is Jessica Chastain's age. I'd recommend this movie however the part where she can't afford health insurance is ridiculous. Nurses are well paid and have excellent benefits. I'm a doctor so the whole hospital bashing was so over the top and made the scapegoat for the benefit of hollywood drama.
