A nurse is performing Leopold's maneuvers on a pregnant client at 38 weeks gestation who is a primigravida. During the third maneuver, the nurse palpates a hard, round, ballotable part in the lower uterine segment. What is the most appropriate nursing assessment to perform next?

A ballotable hard part in the lower segment suggests breech presentation, requiring fetal heart rate assessment and evaluation for ECV contraindications. Other options are inappropriate as they assume normal vertex or emergency without further assessment.

Understanding the Clinical Scenario

When performing Leopold's maneuvers at 38 weeks gestation, the third maneuver is specifically designed to identify the presenting part — the fetal structure occupying the lower uterine segment. In a primigravida at term, you would typically expect to palpate the soft, irregularly shaped buttocks (breech) or the hard, round, smooth head (vertex). The finding described — a hard, round, ballotable part — is the classic description of the fetal head. However, the critical detail here is its location: the lower uterine segment. This confirms the fetal head is not engaged in the pelvis but is instead freely movable above the pelvic inlet, a presentation known as an unengaged vertex or floating head ^[1].

Why Assess for External Cephalic Version (ECV) Contraindications?

The immediate next step is not to document this as a normal finding and continue routine care, because an unengaged presenting part at term in a primigravida warrants further evaluation. The primary concern is to confirm the precise fetal presentation (which may still be a deflexed head, brow, or face presentation) and to determine if the fetus is a candidate for External Cephalic Version (ECV) if a malpresentation is confirmed on ultrasound. Major international guidelines recommend offering ECV at term to eligible women with non-cephalic presentations to reduce cesarean delivery rates ^[1]. Therefore, the most appropriate next nursing assessment is to gather data that will inform this clinical decision.

Specifically, assessing the fetal heart rate (FHR) is the immediate priority to confirm fetal well-being before any further manipulation or intervention is considered. A reassuring FHR tracing is a prerequisite for ECV [1,2]. Simultaneously, the nurse must assess for contraindications to ECV, which include non-reassuring fetal status, placental abruption, severe oligohydramnios, ruptured membranes, and uterine anomalies, among others [1,4]. This assessment directly supports the informed consent process and the development of a safe management plan, which is a core nursing responsibility ^[1].

Analysis of Incorrect Options

- Option 2: Document the finding as normal vertex presentation and continue routine care. This is premature and potentially unsafe. An unengaged presenting part at term in a primigravida is not a routine finding; it requires investigation to rule out malpresentation, placenta previa, or other anomalies that could be causing the high presenting part. Simply documenting without further assessment misses a critical window for intervention.
- Option 3: Immediately notify the healthcare provider about possible cord prolapse. Cord prolapse is a risk when the presenting part is not well-applied to the cervix and membranes rupture. However, with intact membranes and no report of rupture, an immediate emergency notification is an overreaction. The priority is a thorough assessment to gather data, not to escalate based on a potential but unconfirmed complication.
- Option 4: Position the client in Trendelenburg position to promote fetal descent. The Trendelenburg position is sometimes used to relieve cord compression in cases of prolapsed cord or to attempt to disengage an impacted presenting part during ECV ^[1]. It does not promote fetal descent; in fact, it uses gravity to move the fetus away from the pelvis. This intervention is not indicated based solely on the finding of an unengaged head.

Connecting Assessment to Clinical Management

The nurse's assessment of FHR and ECV contraindications is a direct bridge to evidence-based practice. Studies evaluating ECV protocols highlight that patient selection, including a thorough pre-procedure assessment of fetal well-being and maternal-fetal conditions, is a key preparatory measure for a successful and safe version [1,2]. Successful ECV is associated with a lower risk of cesarean delivery, and factors such as a non-engaged presenting part (making the fetus easier to manipulate) are actually favorable for ECV success [2,4]. By performing this targeted assessment, the nurse identifies a potentially modifiable situation (a malpresentation correctable by ECV) and facilitates a timely, guideline-based intervention that can significantly alter the birth outcome.
