Which of the following assessments would be suspicious for hyperemesis gravidarum?

A. Vaginal exams are appropriate in this scenario. Assessing cervical dilation, effacement, fetal station, and position is critical at this stage of labor to determine whether the client is ready to begin pushing. Performing the exam helps guide safe labor management and supports maternal and fetal outcomes.

B. Vaginal exams are contraindicated in the presence of unexplained vaginal bleeding during pregnancy, particularly in the third trimester, because the bleeding could indicate placenta previa, vasa previa, or other serious placental issues. Performing a vaginal exam in such cases risks provoking severe hemorrhage, leading to maternal hypovolemic shock and fetal compromise. Before performing any vaginal examination, the cause of bleeding must be evaluated using non-invasive methods such as ultrasound, fetal monitoring, and laboratory studies. Even if the client is asymptomatic for pain, the risk of disrupting placental attachment makes vaginal exams unsafe.

C. Vaginal exams are safe and routine in latent labor. They help monitor cervical progression, effacement, and fetal position. Frequent exams may be limited to reduce infection risk, but there is no absolute contraindication in a low-risk latent labor client.

D. Vaginal exams are generally indicated after rupture of membranes to monitor labor progress. However, precautions must be taken to maintain aseptic technique and reduce the risk of infection (chorioamnionitis). Unless other contraindications exist (such as vaginal bleeding from placenta previa or signs of infection), the exam is considered safe and clinically necessary.

A. Placing the client in a knee-chest position is not necessary for routine assessment of contractions. This position may be used for specific interventions, such as relieving cord compression, but it does not aid in safe palpation of contractions.

B. Pushing down forcefully before each contraction is unsafe. Forceful palpation can increase discomfort, alter contraction patterns, or compromise fetal oxygenation, especially if uterine tone is high or the fetus is compromised.

C. Avoiding palpation entirely would limit the nurse’s ability to assess contraction frequency, duration, and intensity, which are essential parameters for evaluating labor progress and fetal well-being. Complete avoidance is not recommended unless contraindicated for specific reasons.

D. Palpating gently between contractions to assess uterine tone is the safest and most effective method. It allows the nurse to evaluate baseline uterine tone, contraction frequency, and strength without interfering with fetal oxygenation or increasing maternal discomfort. Gentle palpation helps detect hypertonicity or tetanic contractions, which can lead to fetal distress or uterine rupture if unrecognized.
