The nurse is caring for a 24-year-old woman who is G1P0 at 40 weeks, 1 day gestation and in active labor. She has just received an epidural and now complains of “an itchy feeling all over.” Her vitals are as follows: HR 120, RR 12, BP 130/74, T 98.8, and O2 sat 98%. Which action should the nurse take first?
