A nurse is assessing a client who is 8 hr postpartum and multiparous. Which of the following findings should alert the nurse to the client's need to urinate?

Choice A reason: Amniotic fluid in the vaginal vault indicates that the membranes have ruptured, but this does not necessarily mean that the client is in labor. Some women may have a slow leak of amniotic fluid for hours or days before labor begins. Rupture of membranes also increases the risk of infection, so the nurse should monitor the client's temperature and fetal heart rate.

Choice B reason: Contractions every 3 to 4 minutes are a sign of labor, but they are not enough to confirm it. The nurse should also assess the duration and intensity of the contractions, as well as the client's response to them. Some women may have false labor contractions, also known as Braxton Hicks contractions, which are irregular, mild, and do not cause cervical changes.

Choice C reason: Pain just above the navel is not a typical sign of labor. It may indicate other problems, such as placental abruption, uterine rupture, or fetal distress. The nurse should report this finding to the nurse midwife and check for other signs of bleeding, shock, or fetal compromise.

Choice D reason: Cervical dilation is the most reliable indicator of labor. It means that the cervix is opening and thinning out to allow the passage of the fetus. The nurse should measure the cervical dilation in centimeters and document it along with the station and effacement of the cervix.

Choice A reason: "You will experience urinary retention." is incorrect, as this statement does not describe a sign preceding the onset of labor. Urinary retention can occur during labor due to pressure from the fetal head or epidural anesthesia, but it is not a sign that labor is imminent. The nurse should encourage the client to void frequently and monitor their bladder status.

Choice B reason: "You will have a decrease in vaginal discharge." is incorrect, as this statement does not describe a sign preceding the onset of labor. Vaginal discharge can increase before labor due to cervical ripening and dilation, which can cause bloody show or mucus plug loss. The nurse should educate the client about normal and abnormal vaginal discharge and when to report it.

Choice C reason: "You will experience a surge of energy." is correct, as this statement describes a sign preceding the onset of labor. A surge of energy, also known as nesting instinct, can occur before labor due to hormonal changes or psychological factors. The nurse should advise the client to conserve their energy and rest as much as possible before labor.

Choice D reason: "You will have a weight gain of 0.5 to 1.5 kilograms." is incorrect, as this statement does not describe a sign preceding the onset of labor. Weight gain can occur during pregnancy due to fetal growth, fluid retention, or increased caloric intake, but it is not a sign that labor is imminent. The nurse should monitor the client's weight and fluid balance and report any sudden or excessive weight gain that may indicate preeclampsia or other complications.
