For clinical purposes, the most accurate definition of preterm and post-term infants is defined as what?
Preterm: Before 38 to 40 weeks of gestation if the infant is SGA post-term, beyond 40 to 42 weeks gestation if the infant is LGA
Preterm: Before 37 weeks of gestation and post-term beyond 42 weeks of gestation; no matter the size for gestational age at birth
Postterm: After 40 weeks of gestation if the infant is large for gestational age (LGA): beyond 42 weeks if the infant is AGA
Preterm: Before 34 weeks of gestation if the infant is appropriate for gestational age (AGA); before 57 weeks if the infant is small for gestational age (SCA)
The Correct Answer is B
The most accurate definition of preterm and post-term infants is based on gestational age at birth. Preterm infants are those born before 37 completed weeks of gestation, and post-term infants are those born after 42 completed weeks of gestation, regardless of their size for gestational age at birth.

Correct Answer is D
Explanation
The most common cause of excessive blood loss after childbirth is the failure of the uterine muscle to contract firmly, which is also known as uterine atony. If the uterus does not contract effectively after delivery, it cannot properly close off the blood vessels that were connected to the placenta, leading to heavy bleeding. Uterine atony can occur due to various factors, such as prolonged labor, multiple births, or the use of certain medications during labor.
Other causes of excessive blood loss after childbirth include retained placental fragments, vaginal or vulvar hematomas, or unrepaired lacerations of the vagina or cervix, but these are less common than uterine atony.
