A nurse is caring for a primigravida client who is experiencing precipitous labor. The cervix is fully dilated, and the fetal head is crowning. Which nursing intervention should the nurse implement first?

A 24-year-old primigravida client arrives at the emergency department in active labor. Her contractions began 3 hours ago and are now occurring every 2-3 minutes, lasting 45-60 seconds. Upon examination, the cervix is completely dilated at 10 cm, and the fetal head is visible at the perineum with crowning occurring.
해설
In precipitous labor with crowning, the priority is to control delivery to prevent maternal perineal trauma and fetal injury. Applying gentle pressure to the fetal head (Ritgen maneuver) slows expulsion, while other options are less immediate or inappropriate.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention during an imminent, uncontrolled delivery in a setting of Precipitous labor (labor lasting less than 3 hours from onset to delivery). The core theme is Emergency Management of Delivery to prevent injury to both mother and fetus. The pathophysiological rationale is that rapid, uncontrolled expulsion of the fetal head can cause severe maternal Perineal lacerations (including third- or fourth-degree tears) and fetal trauma (like intracranial hemorrhage or shoulder dystocia).

Answer Rationale: Key Point! The correct answer is to Apply gentle pressure to the fetal head to control the delivery. This action, often referred to as a modified Ritgen maneuver, involves using a sterile towel to apply gentle pressure against the advancing fetal head during a contraction. This slows the delivery, allowing the perineum to stretch gradually, which is the most immediate action to prevent trauma. In an emergency delivery situation where birth is imminent, controlling the speed of delivery takes precedence over all other preparatory or positioning steps.

Distractor Analysis:
Watch out for confusion! Option ①, "Encourage the client to push," is incorrect because with precipitous labor and crowning, the natural expulsive forces are often overwhelmingly strong. Encouraging more forceful pushing increases the risk of rapid, traumatic delivery. The nurse's role is to coach the client to pant or blow to avoid pushing, thereby helping to control the birth.
Option ②, "Prepare for immediate transfer," is incorrect because when the fetal head is crowning, delivery is seconds to minutes away. Attempting to move the client at this point is unsafe and could result in an unattended delivery during transfer, increasing risks for both.
Option ④, "Position the client in lithotomy," is incorrect. While the lithotomy position is standard for a controlled delivery in a delivery room, it is not the first action in an emergency. The priority is to control the delivery in whatever position the client is currently in (often semi-Fowler's or side-lying). Repositioning can delay the critical intervention of controlling the head and may not be feasible.

Related Concepts: This scenario highlights the ABCs of Emergency Childbirth: A (Airway - clear the infant's airway after birth), B (Breathing - dry and stimulate), C (Circulation - keep warm, clamp cord). However, before the infant is born, the priority is a safe, controlled delivery. Understanding the stages of labor is crucial: the second stage (from full dilation to birth) in precipitous labor requires immediate, hands-on nursing intervention to substitute for the controlled environment of a delivery room.
Concept Summary
ConceptDescriptionNursing Implication
Precipitous LaborLabor lasting < 3 hours from onset to delivery.High risk for trauma, postpartum hemorrhage (PPH), and unprepared birth. Requires constant attendance and readiness to deliver.
CrowningThe fetal head is visible at the vaginal opening and does not recede between contractions.Signifies imminent delivery. Do not leave the client. Begin hands-on delivery techniques.
Ritgen ManeuverTechnique to control delivery of the head and protect the perineum.Apply gentle upward pressure on the fetal chin through the perineum while using the other hand to control the head's extension.
Emergency Delivery Priorities1. Control delivery 2. Support perineum 3. Receive infant 4. Manage cord & placentaSafety over protocol. Deliver in current position if necessary.

Side-by-Side Comparison!
ScenarioPriority Nursing InterventionRationale
Precipitous Labor with Crowning (This case)Apply gentle pressure to control delivery of the head.Prevents maternal perineal trauma and fetal injury from rapid expulsion.
Normal Second Stage Labor in Delivery RoomCoach mother in effective pushing; prepare sterile field; position in lithotomy.Delivery is controlled and expected; focus is on maternal effort and preparation for assisted delivery if needed.
Prolapsed Umbilical CordPosition mother in Trendelenburg or knee-chest; apply upward pressure on presenting part; prepare for emergency C-section.Relieves pressure on the cord to maintain fetal oxygenation (priority is fetal circulation).

Anatomy, Physiology & Pharmacology Points
  • Perineal Body: The muscular tissue between the vagina and anus. Rapid stretching during delivery can cause lacerations extending into the rectum.
  • Fetal Head Molding: The overlapping of the skull bones during passage through the birth canal. Controlled delivery allows for gradual molding, reducing the risk of cephalohematoma or intracranial hemorrhage.
  • Ferguson Reflex: The urge to push triggered by pressure of the presenting part on the pelvic floor. In precipitous labor, this reflex is extremely strong, so the nurse must instruct the client to pant to override it.

Memory Tips
  • Acronym: S.L.O.W. for emergency delivery: Support the head, Let it deliver slowly, Observe for nuchal cord, Wipe mouth & nose.
  • Key Phrase: "When you see crowning, control before you coach, call, or change position."

High-Frequency NCLEX Topics The NCLEX-RN frequently tests priority-setting in obstetric emergencies. Precipitous labor, prolapsed cord, placental abruption, and postpartum hemorrhage are classic scenarios. Remember: Key Point! For imminent delivery, the safe, hands-on delivery of the infant is almost always the priority over calling for help, transferring, or extensive preparation.
Watch Out for Question Variations! The same concept can be tested differently:
  • Symptom Identification: "Which finding indicates a client is experiencing precipitous labor?" (Answer: Rapid progression of dilation, e.g., 8 cm to delivery in 30 minutes).
  • Post-Delivery Priority: "After delivering the infant in a precipitous labor, what should the nurse do next?" (Answer: Dry and stimulate the infant to breathe while keeping warm—focus shifts to newborn ABCs).
  • Maternal Complication: "The nurse is monitoring a client after a precipitous delivery. Which finding is a priority to report?" (Answer: Signs of Postpartum hemorrhage (PPH), such as boggy uterus or heavy bleeding).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in a busy Emergency Department. A young woman, supported by her partner, walks in stating, "The baby is coming now!" She is visibly distressed, bearing down with contractions. A quick visual assessment reveals the fetal head crowning at the perineum.

Nursing Intervention Strategy:
  1. Immediate Action (Do Not Leave): Call for help ("I need OB stat to triage bay 3!") but remain with the client. Use the call light or shout, but do not leave to get supplies.
  2. Control the Delivery: Don gloves if available (improvised barrier if not). Place a clean towel under the client's buttocks. As the head advances with a contraction, place your palm with a towel against it, applying gentle, steady pressure to slow the birth. Instruct the client: "Pant like a dog, don't push! Blow out!"
  3. Deliver the Infant: As the head delivers, check for a nuchal cord (umbilical cord around the neck). If loose, slip it over the head. If tight, clamp and cut it in two places before delivering the body. Support the head as it rotates, then gently guide the delivery of the anterior shoulder, then the posterior shoulder, and the rest of the body.
  4. Newborn Care: Immediately dry the infant vigorously with a towel, clear the mouth and nose with a bulb syringe, and place the infant skin-to-skin on the mother's abdomen, covering both with a warm blanket. Assess breathing and heart rate.
  5. Post-Delivery & Evaluation: Await placental delivery (usually within 30 min). Do not pull on the cord. Fundal massage the uterus to promote contraction and prevent hemorrhage. Continue to monitor mother for signs of shock and infant for transition to extrauterine life.

Patient Safety and Precautions:
  • Infection Control: Use standard precautions. The goal is a clean delivery, not a sterile one, in this emergency setting.
  • Never hold the legs together or attempt to delay birth by pushing the head back in.
  • Documentation: Accurately document the time of birth, Apgar scores, condition of mother and infant, and all interventions performed. This is a legal record of an unexpected event.

Nursing Procedure & Medication Flow In this scenario, medication is not the immediate focus. The procedure is the intervention:
Emergency Delivery Procedure: 1. Call for help. 2. Provide perineal support and control head delivery. 3. Receive infant, clear airway, dry, stimulate. 4. Clamp and cut cord (after 1-3 minutes if infant is stable). 5. Deliver placenta passively. 6. Administer Oxytocin (Pitocin) as ordered post-delivery to prevent PPH.
A Word from Your Senior Nurse "Precipitous deliveries are adrenaline-pumping but also one of the most primal and rewarding experiences in nursing. Your calm presence and decisive action make all the difference. Remember, in any emergency birth, your two main jobs are: 1. Get the baby out safely, and 2. Keep the mother from bleeding. Everything else—the paperwork, the perfect positioning, the full sterile setup—comes after those two priorities are secured. Trust your training, use your hands and your voice to guide the mother, and you'll handle it beautifully."
