The Nurse Is Examining a Patient in Her Third Trimester

The nurse is examining a patient in her third trimester of pregnancy. The patient's weight gain has been within normal limits, she has no swelling of her feet, and she states that she feels great. She states that she has been doing yoga 5 days a week ever since she got pregnant. The nurse understands from this that:

A) The patient has continued her regular prepregnant exercise of walking 5 miles a day.
B) The patient has been doing hydrotherapy baths or using a hot tub.
C) The patient has been bicycling on the trails.
D) The patient has been doing a series of gentle stretches and postures coordinated with deep breathing.
