Chapter 16 On completion of this chapter, the reader will be able to: • Review the factors included in the initial assessment of the woman in labor. • Describe the ongoing assessment of maternal progress during the first, second, third, and fourth stages of labor. • Recognize the physical and psychosocial findings indicative of maternal progress during labor. • Describe fetal assessment during labor. • Identify signs of developing complications during labor and birth. • Incorporate evidence-based nursing interventions into a comprehensive plan of care relevant to each stage of labor. • Recognize the importance of support (family, partner, doula, nurse) in fostering maternal confidence and facilitating the progress of labor and birth. • Analyze the influence of cultural and religious beliefs and practices on the process of labor and birth. • Evaluate research findings on the importance of support from family, partner, doula, and nurse in facilitating maternal progress during labor and birth. • Describe the role and responsibilities of the nurse during emergency childbirth. • Evaluate the impact of perineal trauma on the woman’s reproductive and sexual health. Most hospitals have specific forms, whether paper or electronic, that are used to obtain important assessment information when a woman in labor is being evaluated or admitted (Fig. 16-2, A and B). More and more hospitals now use an electronic medical record; almost all charting is done on computer. Sources of data include the prenatal record, initial interview, physical examination to determine baseline physiologic parameters (e.g., vital signs), laboratory and diagnostic test results, expressed psychosocial and cultural factors, and clinical evaluation of labor status. The nurse should review the woman’s prenatal records carefully, taking note of her obstetric and pregnancy history, including gravidity; parity; and problems such as history of vaginal bleeding, gestational hypertension, anemia, pregestational or gestational diabetes, infections (e.g., bacterial, viral, sexually transmitted), and immunodeficiency status. In addition, the expected date of birth (EDB) should be confirmed. Other important data found in the prenatal record include patterns of maternal weight gain; physiologic measurements such as maternal vital signs (blood pressure, temperature, pulse, respirations); fundal height; baseline fetal heart rate (FHR); and laboratory and diagnostic test results. See Table 8-1 for a list of common prenatal laboratory tests. Common diagnostic and fetal assessment tests performed prenatally include amniocentesis, nonstress test (NST), biophysical profile (BPP), and ultrasound examination. See Chapter 10 for more information. • Time and onset of contractions and progress in terms of frequency, duration, and intensity • Location and character of discomfort from contractions (e.g., back pain, abdominal or suprapubic discomfort) • Persistence of contractions despite changes in maternal position and activity (e.g., walking or lying down) • Presence and character of vaginal discharge or “show” • The status of amniotic membranes such as a gush or seepage of fluid (spontaneous rupture of membranes [SROM]). If there has been a discharge that may be amniotic fluid, she is asked the date and time the fluid was first noted and its characteristics (e.g., amount, color, unusual odor). In many instances a sterile speculum examination and a Nitrazine (pH) and fern test can confirm that the membranes are ruptured (Box 16-1). These descriptions help the nurse assess the degree of progress in the process of labor. Bloody show is distinguished from bleeding by the fact that it is pink and feels sticky because of its mucoid nature. There is very little bloody show in the beginning, but the amount increases with effacement and dilation of the cervix. A woman may report a small amount of brownish-to-bloody discharge that may be attributed to cervical trauma resulting from vaginal examination or coitus (intercourse) within the last 48 hours. The woman’s general appearance and behavior (and that of her partner) provide valuable clues to the type of supportive care she will need. However, keep in mind that general appearance and behavior may vary, depending on the stage and phase of labor (Table 16-1 and Box 16-3). TABLE 16-1 EXPECTED MATERNAL PROGRESS DURING FIRST STAGE OF LABOR *In the nullipara effacement is often complete before dilation begins; in the multipara it occurs simultaneously with dilation. †Duration of each phase is influenced by such factors as parity; maternal emotions; position; level of activity; and fetal size, presentation, and position. For example, the labor of a nullipara tends to last longer, on average, than the labor of a multipara. Women who ambulate and assume upright positions or change positions frequently during labor tend to experience a shorter first stage. Descent is often prolonged in breech presentations and occiput posterior positions. ‡Women who have epidural analgesia for pain relief may not demonstrate some of these behaviors. As the population in the United States and Canada becomes more diverse, it is increasingly important to note the woman’s ethnic or cultural and religious values, beliefs, and practices to anticipate nursing interventions to add or eliminate from an individualized, mutually acceptable plan of care that provides a feeling of safety and control (Fig. 16-3). Nurses should be committed to providing culturally sensitive care and developing an appreciation and respect for cultural diversity (Callister, 2008). Encourage the woman to request specific caregiving behaviors and practices that are important to her. If a special request contradicts usual practices in that setting, the woman or the nurse can ask the woman’s primary health care provider to write an order to accommodate the special request. For example, in many cultures it is unacceptable to have a male caregiver examine a pregnant woman. In some cultures it is traditional to take the placenta home; in others the woman has only certain nourishments during labor. Some women believe that cutting her body, as with an episiotomy, allows her spirit to leave her body and that rupturing the membranes prolongs, not shortens, labor. It is important to explain the rationale for required care measures carefully (see Cultural Competence box). The initial physical examination includes a general systems assessment and an assessment of fetal status. During the examination uterine contractions are assessed, and a vaginal examination is performed. The findings of the admission physical examination serve as a baseline for assessing the woman’s progress from that point. The information obtained from a complete and accurate assessment during the initial examination serves as the basis for determining whether the woman should be admitted and what her ongoing care should be. Expected maternal progress and minimal assessment guidelines during the first stage of labor are presented in Table 16-1 and Box 16-4.
