anna is an 18-year-old american indian who gave birth to her son thomas three months ago (he was premature). she has been a heavy smoker and drinker for the past 4 years and didn't stop during her pregnancy. last month thomas had an uri, but recovered completely. even though the doctor recommended that the baby sleep on his back, he seems so peaceful when he lays on his stomach that anna doesn't bother him. one morning anna went in to get thomas up for breakfast, but he was dead. based on the most probable diagnosis, what could anna have done to reduce the baby's risk factors? choose all that apply.
