Final answer:
A nurse should offer reassurance, education on labor preparation and pain management options, and support to a pregnant client who is concerned about labor. Discussing the stages of labor and available medical interventions can help alleviate fears.
Step-by-step explanation:
An appropriate nursing response for a client who is 39 weeks pregnant and has concerns about labor would be to provide reassurance, education, and support. The nurse can discuss labor preparation, pain management options, and the stages of labor to help the client understand what to expect. Offering a childbirth class or resources for additional information could also be beneficial. For example, talking about the body's natural process during labor and the medical interventions available such as epidurals or IV pain medication could help alleviate some fears. The nurse should also encourage the client to express her feelings and ask questions, providing a supportive environment for her to discuss any concerns.
