Final answer:
The outcomes of the at-risk newborn are influenced by factors such as birth weight, gestational age, the type and length of newborn illness, environmental factors, and maternal factors.
Step-by-step explanation:
Factors that influence the outcomes of the at-risk newborn include:
- Birth weight: Low birth weight is a significant risk factor and is often caused by premature birth or intrauterine growth restriction (IUGR). A newborn weighing less than 2.5 kg (5.5 lb.) is considered to have a low birth weight.
- Gestational age: Preterm infants, born before 37 weeks of gestation, are at higher risk due to underdeveloped organ systems, especially the lungs and brain.
- Type and length of newborn illness: The severity and duration of any illness can significantly impact the newborn's health outcomes.
- Environmental factors: These include the presence of infections, exposure to harmful substances, and general care standards, all of which can affect the newborn's development and health.
- Maternal factors: The health and nutrition of the mother during pregnancy, as well as her access to prenatal care, are critical for the baby's growth and development.
