Intrapartum Assessment and Labor Comfort Measures

Distinguishing between true and false labor is an essential intrapartum nursing skill. True labor is characterized by contractions that become progressively stronger, closer together, and regular over time. Most importantly, true labor produces progressive cervical dilation and effacement. In contrast, contractions associated with false labor typically decrease in intensity or frequency when the client walks or changes position. Think of true labor as an established physiological sequence that gains momentum regardless of maternal movement, whereas false labor contractions ease with activity adjustments.

Maternal anatomical changes signal approaching labor. Lightening describes the descent of the fetal head into the pelvic cavity. While this downward movement relieves maternal dyspnea by reducing pressure against the diaphragm, it commonly increases urinary frequency due to direct compression on the bladder. Additionally, clients may observe bloody show, which consists of pink or blood-tinged mucus expelled from the vagina as the cervix softens and dilates.

When rupture of membranes occurs, the immediate nursing priority is to assess the fetal heart rate to detect potential umbilical cord compression or prolapse. Amniotic fluid is normally clear and pale yellow without a foul odor. If the amniotic fluid is green or brownish, it is meconium-stained; this finding warrants close fetal heart rate monitoring, although it does not necessarily indicate fetal hypoxia. To confirm whether membranes have ruptured, nurses may use Nitrazine paper, which turns blue at an alkaline pH (typically 6.5 or higher). However, clinicians must remember that blood, semen, and infection can cause false-positive Nitrazine results. Under microscopy, dried vaginal fluid displaying a ferning pattern also supports the presence of amniotic fluid, though false-positive results can likewise occur.

Nonpharmacologic comfort measures provide significant relief during active labor. When a fetus presents in an occiput posterior position, persistent lower back discomfort often results; applying firm counterpressure to the maternal sacrum effectively counteracts this back pain. For general labor discomfort, effleurage, a technique involving light, rhythmic abdominal stroking, serves as a beneficial tactile distraction during contractions. Pregnant clients are screened for Group B Streptococcus colonization at 36 0/7 through 37 6/7 weeks; those with a positive result generally receive intrapartum antibiotic prophylaxis, with the drug selected according to allergy history, but prophylaxis is not indicated for a planned cesarean birth before labor with intact membranes.
