A client who is primigravida at term comes to the prenatal clinic and tells the practical nurse (PN) that she is having contractions every 5 minutes. The PN monitors the client for one hour using an external fetal monitor, and determines that the client's contractions are 7 to 15 minutes apart, lasting 20 to 30 seconds, with mild intensity by palpation. Which action should the PN take?

A. The client's contractions are not regular or intense enough to indicate active labor, so immediate hospital admission is not necessary. B. Instructing the client to call the clinic when her contractions occur 5 minutes apart for one hour ensures she is monitored for the progression of labor and can seek timely assistance when labor becomes more active. C. While a urinary tract infection could cause contractions, the primary focus should be on monitoring labor progression, not diagnosing a UTI at this stage. D. Hydration is important, but the primary instruction should relate to monitoring contraction patterns for signs of active labor.
