Explanation

An amniotomy, or artificial rupture of membranes (ARM), is a procedure to induce or augment labor. Its most critical and immediate risk is umbilical cord prolapse.
Cord prolapse is an obstetric emergency where the umbilical cord descends ahead of the fetus. This can lead to cord compression, cutting off the oxygen and blood supply to the baby.
The most immediate and sensitive indicator of umbilical cord compression is a sudden change in the Fetal Heart Rate (FHR), most commonly bradycardia (a rate below 110 bpm) or severe variable decelerations.
Therefore, assessing the FHR immediately before and after the procedure is the highest priority nursing action to confirm fetal well-being and rule out this life-threatening complication.

Option B: While assessing the amniotic fluid for meconium is important, it is not the first priority. A stable FHR confirms immediate fetal viability, which is a more urgent concern than the characteristics of the fluid.
Option C: Encouraging ambulation is unsafe immediately after an amniotomy because it increases the risk of the umbilical cord prolapsing, especially if the fetal head is not firmly engaged in the pelvis.
Option D: Assessing maternal vital signs is a routine part of labor care, but it is not the immediate priority after an amniotomy. The most acute, life-threatening risk is to the fetus, not the mother.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Priority nursing interventions following an amniotomy in the correct sequence, documenting the action clearly, and monitoring for the expected response.
A nurse must always prioritize fetal safety after an amniotomy. The FHR should be auscultated for a full minute immediately following the procedure.
Any significant drop in the FHR is an emergency. The nurse's immediate actions should be to reposition the mother (e.g., knee-chest or Trendelenburg position) to relieve pressure on the cord, administer oxygen, and call for immediate assistance.
What if? If the amniotomy is performed and the FHR drops to 85 bpm and stays there, the priority is no longer just assessment. The nurse must intervene immediately by manually lifting the presenting part off the cord, repositioning the mother, and preparing for an emergency cesarean section. Assessment has identified a life-threatening problem that now requires immediate action.

How to Approach the Question

First, identify the core of the question: it asks for the 'first priority' action.
Next, understand the procedure mentioned: amniotomy (artificial rupture of membranes).
Recall or deduce the most critical, life-threatening complication associated with this procedure. For amniotomy, this is umbilical cord prolapse.
Analyze the options to see which one directly assesses for or prevents this primary complication.
Option A (assess FHR) is the most direct way to check for cord compression, the immediate effect of a prolapse.
Evaluate the other options: Assessing fluid is important but secondary. Ambulation is dangerous. Assessing maternal vitals is routine but not the immediate priority. Therefore, assessing FHR is the correct first action.
