D. A distended bladder can displace the uterus, causing the fundus to deviate from the midline. This deviation is due to the bladder pushing the uterus to one side, which interferes with uterine contraction and can lead to complications like uterine atony and excessive bleeding.A. Frequent uterine contractions are normal in the immediate postpartum period as the uterus contracts to reduce in size (involution). These contractions help control bleeding and aid in returning the uterus to its pre-pregnancy state. While uterine contractions are expected, they do not directly indicate bladder distention.B. Lochia is the vaginal discharge that occurs after childbirth, progressing through stages (rubra, serosa, alba) over several weeks. A small amount of rubra lochia (bright red, indicating recent bleeding) on the perineal pad suggests minimal postpartum bleeding, which is a normal finding. However, it does not directly indicate bladder distention.C. Increased thirst can occur postpartum due to fluid shifts, hormonal changes, and breastfeeding. While hydration status is important, increased thirst alone does not directly indicate bladder distention.
