A nurse is caring for a client in the labor and delivery unit. Which of the following findings indicate that the client is in labor Select all that apply.

A. Urinalysis: The urinalysis shows leukocyte esterase positivity, which suggests a possible urinary tract infection rather than an indication of labor. While infections can contribute to discomfort and complications, urinalysis findings do not confirm the onset of labor and therefore are not considered indicators of labor progress. B. Contraction intensity: The client reports contractions that are becoming stronger over the last few hours, with pain rising to 8 out of 10 during contractions. Increasing contraction intensity is a typical sign that labor is progressing, as contractions become more forceful and effective in promoting cervical change. C. Cervical dilation: The last cervical exam was performed five days ago and showed no dilation, and the current scenario provides no evidence of updated cervical assessment. Without current cervical findings, dilation cannot be used as an indicator of labor at this time, even though it is a defining feature when assessed directly. D. Vaginal discharge: The client has been wearing a perineal pad for discharge for three days, but this chronic discharge does not necessarily represent labor onset. Vaginal discharge can increase during pregnancy for many benign reasons and requires nitrazine testing or other characteristics to confirm rupture of membranes. E. Nitrazine results: The nitrazine test is positive, which suggests that the fluid may be amniotic rather than standard vaginal secretions. Rupture of membranes, whether spontaneous or premature, is an important sign associated with labor or imminent labor progression and requires follow-up assessment. F. Maternal temperature: The temperature of 38.7°C (101.7°F) indicates a fever and raises concern for infection, such as chorioamnionitis or a urinary infection. A fever does not indicate labor directly; instead, it signals a need for medical evaluation to determine the cause and potential fetal implications. G. Contraction frequency: Contractions occurring every five minutes for at least one hour suggest a rhythmic pattern typical of early labor. When contractions become regular and progressively closer together, this pattern is consistent with true labor rather than Braxton Hicks contractions. H. Fetal heart rate: The fetal heart rate of 140 beats per minute is within normal limits for a term fetus and does not indicate labor progression. FHR trends help evaluate fetal well-being but do not provide specific information confirming the presence or advancement of labor.
