Final answer:
The fundus should be palpated at the level of the umbilicus 8 hours after delivery to assess uterine contraction and involution.
Step-by-step explanation:
The LVN should palpate the fundus at the level of the umbilicus 8 hours after delivery. Immediately postpartum, the uterus begins to contract and shrink back to its pre-pregnancy size in a process called involution. During this time, healthcare providers will monitor the position of the uterus to ensure it is contracting properly.
The location of the fundus, which is the top of the uterus, is typically at the level of the umbilicus (belly button) immediately after the birth, then it starts to descend eventually. It is important for the LVN to palpate the fundus at the correct location to assess proper involution and to ensure there are no complications such as uterine atony, which can lead to postpartum hemorrhage.
