A nurse is performing Leopold's maneuvers on a pregnant client at 36 weeks gestation. During the third maneuver, the nurse palpates a hard, round, ballotable structure in the lower uterine segment. What is the most appropriate nursing action?
1Document the findings as vertex presentation and continue routine care
2Immediately notify the healthcare provider of possible cord prolapse
3Position the client in Trendelenburg position to prevent complications
4Document the findings as breech presentation and inform the healthcare provider✓ 정답
해설
A hard, round, ballotable structure in the lower uterine segment during the third Leopold's maneuver indicates breech presentation, which increases risks like cord prolapse. The nurse should document this finding and notify the healthcare provider for further evaluation and management planning.
Understanding the Third Leopold Maneuver
The third Leopold maneuver, also known as Pawlik's grip, is performed to determine the presenting part of the fetus. The nurse grasps the lower uterine segment, just above the symphysis pubis, between the thumb and fingers. The goal is to identify whether the presenting part is the head (cephalic/vertex) or the breech (buttocks/feet).
Interpreting the Findings
The question describes palpating a "hard, round, ballotable structure." This is the classic description of the fetal head. The head feels firm, smooth, and globular, and it can be gently displaced (balloted) between the examining fingers. In contrast, the breech feels softer, more irregular, and less defined. The finding of a hard, round, ballotable structure in the lower uterine segment indicates that the head is the presenting part. This is a vertex presentation.
Analyzing the Correct Answer
The correct action is to document the findings as a vertex presentation and continue routine care. A vertex presentation at 36 weeks gestation is a normal, expected finding. It confirms the fetus is in the optimal position for a vaginal delivery. No immediate intervention or provider notification is required for this normal assessment.
Rationale for Incorrect Options
- Option 2 (Immediately notify the healthcare provider of possible cord prolapse): A cord prolapse is a risk when the presenting part is not well-applied to the cervix, such as with a breech or transverse lie, or when the presenting part is high and not engaged. A hard, ballotable head firmly in the lower uterine segment is well-applied, making a cord prolapse unlikely.
- Option 3 (Position the client in Trendelenburg position to prevent complications): The Trendelenburg position is an emergency intervention used to relieve pressure on a prolapsed umbilical cord. Since the assessment reveals a normal vertex presentation, this action is unnecessary and incorrect.
- Option 4 (Document the findings as breech presentation and inform the healthcare provider): This option incorrectly interprets the physical assessment. A breech presentation is characterized by a soft, irregular mass in the lower uterine segment. The hard, round, ballotable structure is the fetal head, confirming a vertex, not a breech, presentation.
Clinical Assessment Guide
When performing Leopold's maneuvers, systematically interpret each step. The third maneuver (Pawlik's grip) is critical for confirming the presenting part. A hard, round, ballotable mass is the fetal head, indicating a vertex presentation. This is the expected normal finding near term. Differentiate this from the soft, irregular breech. Document the vertex presentation and continue routine prenatal care; no urgent intervention is needed for this normal assessment.
Breech (Buttocks): Soft, irregular, less defined, continuous with the back.
Nursing Alert: Do not confuse a normal vertex finding with an emergency. Cord prolapse is associated with a non-engaged presenting part (e.g., breech, transverse lie) and presents with a palpable cord or variable decelerations.
Leopold's Maneuvers — Leopold's maneuvers. A four-step physical examination technique that systematically palpates the pregnant woman's abdomen to assess fetal position, lie, presentation, and engagement.
Breech Presentation — Breech presentation. A fetal position where the baby's buttocks (breech) or feet are the presenting part (the part that comes out first). Compared to cephalic presentation (head-first), it carries a higher risk of delivery complications, requiring careful evaluation and management.
Ballotable — Floating, moving intermittently. In medical palpation, a term describing the sensation of a structure within fluid being pushed away when pressed and then returning when the finger is released. In Leopold's maneuvers, it indicates the fetal head floating in fluid (amniotic fluid).
Vertex Presentation — Vertex presentation. The fetal head (anterior fontanelle) becomes the presenting part in a normal fetal attitude. It is considered the most favorable fetal attitude for delivery.
Lower Uterine Segment — Lower uterine segment. The lower part of the uterus during late pregnancy and labor. It is the anatomical region between the cervix and the uterine body, and is also the site where the incision is made during a cesarean section.
