Immediately after birth and expulsion of the placenta, where is the fundus located? Select the correct letter on the diagram that represents this exact fundal position.

Rationale: A. A is correct because immediately after birth and expulsion of the placenta, the uterine fundus is typically at the level of the umbilicus, which corresponds to a 20-week gestational height on standard pregnancy diagrams. This position reflects the normal size of the uterus at the time of delivery before it begins the process of involution. Monitoring the fundal height at this time helps ensure that the uterus is contracting properly and that postpartum hemorrhage is not occurring. B. B is incorrect because the 15-week level is too low for the immediate postpartum period. At this height, the fundus would have already involuted several days after birth, so using it as a reference immediately after delivery could mask complications. C. C is incorrect because the 19-week level is slightly below the expected position for the uterus immediately after birth. Using this measurement could lead to inaccurate assessment of uterine tone and potentially delay recognition of hemorrhage or subinvolution. D. D is incorrect because the 12-week level represents a much lower fundal height that occurs only after several days of uterine involution. Measuring the fundus at this level immediately postpartum would indicate abnormal uterine contraction or significant atony, which requires prompt intervention
