What is the first action a nurse should take if a postpartum client with an epidural morphine has a respiratory rate of 10/min?

In the case of a postpartum client who has an epidural morphine and presents with a respiratory rate of 10/min, the most appropriate first action is to administer oxygen by nonrebreather face mask. This is crucial because a respiratory rate of 10/min indicates significant respiratory depression, which can lead to hypoxia.

Administering oxygen helps to ensure that the client receives adequate oxygenation to prevent complications related to low oxygen levels, such as brain injury or cardiac distress. As the nurse recognizes the potential urgency of this situation, supplemental oxygen is a critical intervention to stabilize the patient while further assessments or treatments are considered.

Once the immediate oxygenation needs are addressed, the nurse can then proceed to carry out further assessments, notify the physician, or consider administering naloxone. However, establishing and maintaining adequate oxygenation is the primary concern in this scenario, as it directly impacts the client's immediate safety and wellbeing.
