The classification of "term newborn infants" specifically refers to infants who are born between 37 and 42 weeks of gestation and are typically defined as being within the first 28 days of life after birth. This time frame is critical in neonatal care as it encompasses the period where infants are most vulnerable and require careful monitoring and support.

According to the provided guidelines, the correct age range for term newborn infants is 0 to 27 days. This definition aligns with health standards that stipulate that the first month of life should be observed, particularly the first 28 days post-birth, which is a crucial time for assessing an infant's health and development. The distinction of being up to 27 days rather than including the full 28 days is important for precise categorization in medical settings.

The other age ranges presented do not apply to the classification of term newborn infants. The range of 28 days to 23 months pertains more to infants and toddlers, while the 2 to 11 years range includes children who are not newborns at all. Therefore, selecting the age range of 0 to 27 days accurately reflects the established medical practice and guidelines regarding term newborn infants.
