A primigravida client at 38 weeks gestation arrives at the emergency department with strong, continuous contractions occurring every 1-2 minutes. The cervix is 8 cm dilated and 100% effaced. What is the nurse's priority action?

해설
In precipitous labor with 8 cm dilation and contractions every 1-2 minutes, delivery is imminent. The nurse's priority is to prepare for emergency delivery and immediately notify the physician. Other options (cesarean, IV fluids/meds, transfer) are not appropriate as they delay immediate delivery.

Core Nursing Explanation Key Concept Analysis: This question tests the nurse's ability to recognize and respond to precipitous labor, which is defined as labor lasting less than 3 hours from onset of contractions to delivery. The client is a primigravida (first pregnancy) at term (38 weeks) with advanced cervical dilation (8 cm) and very frequent, strong contractions. This indicates that birth is imminent and will likely occur within minutes, not hours. The priority shifts from standard labor management to preparing for an unplanned, rapid delivery in the current location (the ED).

Answer Rationale: Key Point! When a client presents in active labor with advanced dilation and a rapid contraction pattern, the nurse's first responsibility is to ensure a safe delivery for both mother and baby. Option ③ is correct because it combines the two critical, immediate actions: preparing for emergency delivery (gathering supplies, positioning the client, preparing to receive the newborn) and calling the physician immediately to alert them to the emergency and request their presence or remote guidance. Delaying to transfer or administer medications could result in an unattended delivery.

Distractor Analysis:
  • Watch out for confusion! Option ① (Prepare for cesarean): Cesarean delivery is a major surgical procedure requiring time for preparation, consent, and anesthesia. It is not indicated simply for rapid labor if there are no signs of fetal distress or maternal complications like placenta previa or cord prolapse.
  • Option ② (Administer IV fluids and pain medication): In imminent delivery, administering systemic pain medication (like opioids) is contraindicated because it can cause respiratory depression in the newborn. IV fluids are supportive but are not the priority when the baby is about to be born.
  • Option ④ (Transfer to L&D): While the labor and delivery unit is the ideal location, transferring a client who is 8 cm dilated with contractions every 1-2 minutes is unsafe. The baby could be delivered during transfer, in an elevator, or hallway, without necessary equipment or support, posing significant risk.
Related Concepts: This scenario highlights the principles of triage and emergency obstetric care. The nurse must perform a rapid assessment, recognize the stage of labor, and act to prevent an unattended birth. Knowledge of the phases of the first stage of labor (latent, active, transition) is crucial for making this judgment.

Side-by-Side Comparison!
SituationNursing Priority ActionRationale
Precipitous Labor (e.g., 8 cm in ED)Prepare for emergency delivery in current location & call physician.Birth is imminent. Transfer is unsafe. Focus is on supporting a vaginal delivery.
Prolapsed Umbilical CordPosition client in Trendelenburg or knee-chest, apply sterile gloved hand to lift presenting part off cord, call for immediate cesarean.Goal is to relieve pressure on the cord to prevent fetal hypoxia. This is a true obstetric emergency requiring rapid surgical intervention.
Normal Active Labor (e.g., 4 cm on L&D unit)Continue monitoring, provide comfort measures, support birth plan.There is time for standard labor management, pain control options, and gradual progression.

Anatomy, Physiology & Pharmacology Points
  • Physiology: Cervical dilation from 8 to 10 cm is the transition phase, often the most intense and shortest phase of the first stage of labor. Contractions are strong, frequent (every 2-3 minutes), and long (60-90 seconds).
  • Pharmacology Caution: Administering opioid analgesics during the transition phase or when delivery is imminent can lead to neonatal respiratory depression. The drug crosses the placenta and has its peak effect when the baby is born.

Memory Tips
  • Acronym: D.I.R.T. for imminent delivery: Don't leave, Inform MD/team, Ready the delivery kit, Time to deliver!
  • Rule of Thumb: If a pregnant client is having contractions and feels the urge to bear down or you see the baby's head (crowning), the baby is coming NOW. Your job is to "catch," not to "transfer."

High-Frequency NCLEX Topics NCLEX frequently tests the nurse's ability to prioritize actions in obstetric emergencies. Precipitous labor is a classic scenario. Remember: Safety first. When birth is imminent, you provide supportive care for a vaginal delivery where the client is. NCLEX wants you to choose the action that prevents harm (e.g., unattended birth) over routine procedures (e.g., transfer).

Watch Out for Question Variations!
  • Symptom Focus: "The nurse observes crowning. What is the priority action?" (Answer: Instruct client to pant/blow, support perineum, deliver head slowly).
  • Intervention Focus: "Which equipment is most important for the nurse to obtain immediately?" (Answer: Sterile delivery kit, bulb syringe, dry blankets).
  • Post-Delivery Focus: "After an emergency delivery, the nurse notes the placenta has not delivered. What is the priority?" (Answer: Monitor for signs of hemorrhage; do not pull on cord).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in a busy Emergency Department. A 24-year-old patient, G1P0, is wheeled in by her partner. She is crying out with pain, clutching her abdomen. She states her "water broke" an hour ago and contractions started suddenly and became very strong very quickly. Your rapid assessment reveals contractions every 90 seconds, lasting 70 seconds, of strong intensity. A sterile speculum exam shows the cervix is 8 cm dilated, 100% effaced, and the fetal head is at +1 station.

Nursing Intervention Strategy:
  1. Immediate Action & Communication: Stay with the patient. Use the call bell or shout for another nurse/tech to: a) Immediately page the OB physician and ED physician STAT to the bedside. b) Bring the emergency delivery ("crash") cart to the room.
  2. Preparation & Environment: Help the patient onto the ED stretcher in a semi-Fowler's or side-lying position. Unlock the bottom of the stretcher. While waiting for the cart, gather any available clean supplies: towels, blankets, a bulb syringe. Once the cart arrives, open the sterile delivery pack.
  3. Delivery Support: If the physician is not yet present and delivery is progressing (crowning), you must be prepared to assist. Don sterile gloves. Instruct the patient to pant or blow during contractions to slow the delivery of the head. Support the perineum with a sterile towel. As the head delivers, check for a nuchal cord. Suction the mouth then nose with the bulb syringe. Guide the delivery of the shoulders, supporting the body as it is born.
  4. Newborn Care: Dry the newborn vigorously with warm blankets, stimulate by rubbing the back, and place skin-to-skin on the mother's abdomen. Assess respirations, heart rate, color, and tone. Clamp and cut the cord once pulsations stop (if sterile clamps are available). Keep the newborn warm.
Patient Safety and Precautions:
  • DO NOT attempt to hold the baby in or push the head back in.
  • DO NOT leave the patient alone.
  • DO NOT transfer the patient to L&D or for imaging.
  • Contraindication: Do not administer pain medication if delivery is imminent due to risk to the newborn.
  • Key Monitoring: Monitor maternal vital signs for signs of shock (postpartum hemorrhage risk). Monitor newborn for effective transition (Apgar scores).

Nursing Procedure & Medication Flow Emergency Vaginal Delivery Procedure (When Provider is Not Present): 1. Call for help. 2. Position mother. 3. Control delivery of head ("hands off" until crowning, then support). 4. Check for cord around neck. 5. Suction airway. 6. Deliver shoulders (anterior first, then posterior). 7. Receive baby. 8. Dry, stimulate, warm. 9. Place on mother. 10. Deliver placenta (do not force).
Medication Note: In this scenario, the priority is delivery, not medication administration. After delivery, medications like Oxytocin (Pitocin) may be ordered to promote uterine contraction and prevent hemorrhage, but this is after the emergency phase.

A Word from Your Senior Nurse "Labor doesn't always follow the textbook timeline, and babies have a habit of arriving on their own schedule! This scenario is about thinking on your feet and trusting your assessment. Your eyes and hands are your best tools—if you see advanced dilation and the patient can't talk through contractions, assume delivery is minutes away. Your calm presence and clear actions can turn a chaotic, scary moment for the family into a safe and supported birth. In the NCLEX and in real life, the mantra is: Assess, Act for safety, then Alert. You've got this!"
