Final answer:
Shaun will likely notice emerging adults with a variety of injuries in the emergency room, as this age group engages in activities that may lead to such emergencies.
Step-by-step explanation:
As Shaun takes on the role of an emergency room nurse, he is likely to notice emerging adults with a variety of injuries. The term 'emerging adults' refers to individuals in a newly defined period of lifespan development from 18 years old to the mid-20s. This is a demographic that tends to engage in a range of activities that may lead to injuries requiring emergency care. While the baby boomer population is more associated with chronic conditions such as heart disease, cancer, and stroke, emerging adults are less likely to be afflicted by these conditions and do not frequently require medication dosages that deviate from typical ranges due to chronic illness treatment.
