A nurse is caring for a client who is in the fourth stage of labor and received an epidural during labor. Which of the following actions should the nurse take before ambulating the client to the bathroom?

A. Catheterization may be necessary if the client cannot void but is not the first step before ambulation. B. Evaluating deep tendon reflexes is more relevant for clients receiving magnesium sulfate, not primarily for epidural assessment. C. Assessing motor function of the lower extremities ensures the client has adequate strength and sensation to safely ambulate after an epidural. D. Administering meperidine is for pain management and does not relate to safety before ambulation.
