Final answer:
The nurse should prioritize assessing vital signs, followed by massaging the uterine fundus and administering uterotonic medications. Notifying the healthcare provider should occur if the previous actions do not improve the client's condition.
Step-by-step explanation:
- Assess vital signs: Since uterine atony can lead to excessive bleeding, it is crucial to monitor the client's vital signs, such as blood pressure and heart rate, to detect any signs of hemorrhage.
- Massage the uterine fundus: This helps stimulate uterine contractions and prevents hemorrhage by promoting the expulsion of any retained clots or fragments from the uterus.
- Administer uterotonic medications: Uterotonic medications, such as oxytocin, can be given to enhance uterine contractions and reduce the risk of postpartum hemorrhage.
- Notify the healthcare provider: If the above measures do not improve the client's condition, it is essential to inform the healthcare provider for further evaluation and intervention.
