Which client should the nurse prioritize first in the antenatal unit?

The priority in an antenatal unit often lies in assessing the degree of risk to both the mother and the fetus. In this case, the client experiencing pelvic pressure due to placenta previa requires immediate attention. Placenta previa can lead to serious complications such as heavy bleeding or premature labor, and increased pelvic pressure may signal changes that could prompt these risks.

While hyperemesis gravidarum, preterm labor, and severe pre-eclampsia are also significant conditions that require careful management, the risks associated with placenta previa, particularly in the context of the reported symptoms, elevate the need for immediate evaluation and intervention. Monitoring for potential bleeding and fetal distress in such scenarios is essential because it could affect the safety of both the mother and the child.

Given these factors, prioritizing the client with placenta previa who is experiencing pelvic pressure is crucial for ensuring both maternal and fetal safety.
