Final answer:
The one month old Eskimo female who sleeps on her back is at the lowest risk for SIDS, as back sleeping reduces risk, whereas premature birth, exposure to smoke, family history, and male sex increase it.
Step-by-step explanation:
The baby at lowest risk for Sudden Infant Death Syndrome (SIDS) would be A. A one month old Eskimo female whose parents make sure she sleeps on her back. According to research, certain practices like placing an infant on their back during sleep, avoiding exposure to secondhand smoke, and preventing hyperthermia can significantly reduce the risk of SIDS.
Infants at a higher risk are typically those born premature, exposed to secondhand smoke, or have a sibling who died from SIDS. Therefore, options B, C, and D present higher risks due to factors such as the baby’s sex, prematurity, family history of SIDS, and exposure to tobacco smoke.
