Sudden gush of blood or lengthening of the umbilical cord after the delivery of the infant indicates?

Appeared in: DSSSB Public Health Nurse - 2015

Explanation

  • The question describes the two classic signs of placental separation, which occurs during the third stage of labor.
  • After the baby is born, the uterus contracts significantly, reducing the surface area of the placental attachment site.
  • This size mismatch causes the placenta to buckle and shear off from the uterine wall (decidua).
  • As the placenta detaches, trapped blood is released, causing a sudden gush of blood.
  • The descent of the separated placenta into the lower uterine segment and vagina causes the external portion of the umbilical cord to lengthen.

Why Other Options Were Wrong

  • Option A: Placenta accreta is a condition where the placenta attaches too deeply into the uterine wall, which prevents normal separation. This would lead to a retained placenta and potential for massive hemorrhage, not the classic signs of successful separation.
  • Option B: A retained placenta is the failure of the placenta to be expelled within a set time (e.g., 30 minutes) after the baby's birth. The signs in the question indicate that separation has occurred, which is a prerequisite for expulsion, not retention.
  • Option C: Abruptio placenta is the premature separation of the placenta before the delivery of the infant. The question explicitly states the signs occur after the infant's delivery.

Clinical Relevance
  • Nursing practice connection: Safe nursing care depends on performing Signs of Placental Separation in the Third Stage of Labor in the correct sequence, documenting the action clearly, and monitoring for the expected response.
  • A nurse's primary role during the third stage of labor is to monitor for signs of placental separation and assess for excessive bleeding.
  • Prompt recognition allows for timely intervention and active management, which significantly reduces the risk of postpartum hemorrhage (PPH).
  • The nurse should prepare for placental delivery by having a basin ready and ensuring uterotonic medications (like oxytocin) are available for administration after the placenta is delivered to ensure the uterus remains contracted.
How to Approach the Question
  • First, identify the key timing in the question stem: 'after the delivery of the infant'. This places the event in the third stage of labor.
  • Next, analyze the specific clinical signs described: 'sudden gush of blood' and 'lengthening of the umbilical cord'.
  • Recall the physiological events of the third stage of labor. These are the cardinal signs that the placenta has detached from the uterine wall.
  • Evaluate the options based on this understanding. 'Placental separation' directly matches the event described.
  • Differentiate from the other options by their definitions: Abruptio placenta is premature (before birth), placenta accreta is abnormal adherence (failure to separate), and retained placenta is failure of expulsion after separation.
Concept Tested & Keywords
  • Concept Tested: Signs of Placental Separation in the Third Stage of Labor
  • Stem keywords: Sudden gush of blood, lengthening of the umbilical cord, after the delivery, infant
  • Lead-in keywords: indicates
  • Clinical cues: Timing of event is post-delivery of the infant, which points to the third stage of labor.
