Final answer:
The 'fourth stage of labor' commonly refers to the immediate postpartum period. Nurses should check the funds (uterine fundus) every 15 minutes for the first hour after delivery to prevent postpartum hemorrhage, with the frequency of checks decreasing thereafter according to hospital protocols and patient needs.
Step-by-step explanation:
The question asks how often a nurse should check the funds during the fourth stage of labor. However, there are traditionally considered to be three stages of labor, with the third being the delivery of the placenta. This can lead to some confusion as the term 'fourth stage of labor' is not standard, but it is sometimes referred to as the immediate postpartum period. During this time, it's crucial to monitor for postpartum hemorrhage and ensure that the uterus is contracting properly to prevent excessive bleeding.
After the placenta is delivered, the nurse should conduct fundal checks every 15 minutes for the first hour, as this is when the risk for hemorrhage is highest. These checks consist of palpating the uterus through the abdominal wall to ensure that it is firm, and that it is at or below the level of the umbilicus. As the postpartum period progresses, the frequency of fundal checks may be decreased but should still occur regularly for the first few hours and then periodically during the patient’s hospital stay, according to hospital protocols and the patient's condition.
The rationale behind frequent fundal checks is to assess uterine contraction strength, which helps control bleeding by compressing the blood vessels left open after the placenta separates from the uterine wall. Postpartum hemorrhage is a leading cause of maternal mortality, and immediate intervention is paramount.
