Obstetric Emergencies - NREMT AEMT Level

1. Identify the five components scored in the Apgar assessment.

   Appearance, Pulse, Grimace, Activity, Respirations. These components assess the newborn's color, heart rate, reflex irritability, muscle tone, and breathing effort for a total score out of 10.

2. What is the normal duration range for a full-term pregnancy in weeks?

   Approximately 37 to 42 weeks. Full-term gestation is defined as this range to ensure fetal maturity, with pregnancies outside it considered preterm or post-term.

3. What is shoulder dystocia and the first maneuver typically used to relieve it?

   Anterior shoulder trapped; perform McRoberts maneuver. Shoulder dystocia involves impaction behind the pubic symphysis, and McRoberts maneuver flexes hips to widen the pelvic outlet.

4. What is the immediate field management for a breech presentation with a delivered body?

   Support body; allow head to deliver; do not pull. Supporting without pulling allows natural delivery progression while minimizing risk of nerve injury or trauma in breech presentation.

5. What is the definition of preeclampsia relevant to EMS assessment?

   Pregnancy hypertension with signs such as headache or edema. Preeclampsia involves gestational hypertension often with proteinuria, and symptoms like headache or edema signal potential progression to eclampsia.

6. What is the primary intervention for postpartum hemorrhage in the prehospital setting?

   Fundal massage with support; treat for shock. Fundal massage promotes uterine contraction to control bleeding, while shock treatment addresses hypovolemia in postpartum hemorrhage.

7. What is the correct immediate action if meconium-stained fluid is present at delivery?

   Suction only if airway obstruction or inadequate respirations. Guidelines recommend suctioning only when necessary to avoid unnecessary trauma, as most newborns clear meconium without intervention.

8. What is the best immediate positioning for suspected umbilical cord prolapse?

   Knee-chest or Trendelenburg to relieve cord compression. These positions elevate the presenting part off the cord, reducing compression and maintaining fetal blood flow during transport.

9. What is the correct immediate action if the umbilical cord is around the newborn neck?

   Gently slip cord over head; if tight, clamp twice and cut. This action relieves potential cord compression around the neck, ensuring fetal oxygenation without causing cord trauma.

10. What is the correct management of the delivered placenta in the field?

    Inspect for completeness and transport with the patient. Inspection ensures no retained fragments that could cause infection or bleeding, and transport allows hospital evaluation.

11. What is the correct prehospital positioning for a third-trimester pregnant trauma patient?

    Left lateral tilt to reduce supine hypotensive syndrome. Left lateral positioning displaces the gravid uterus off the inferior vena cava, improving venous return and cardiac output in hypotensive patients.

12. What is the correct immediate care for a newborn who is apneic after initial drying and stimulation?

    Start positive-pressure ventilation with room air or oxygen per protocol. Positive-pressure ventilation supports oxygenation and ventilation when the newborn fails to breathe spontaneously after basic stimulation.

13. What is the correct management if the placenta has not delivered and there is bleeding?

    Do not pull cord; manage hemorrhage and transport rapidly. Pulling risks uterine inversion or increased bleeding, so focus on hemorrhage control and urgent transport for hospital intervention.

14. What is the preferred prehospital management for a limb presentation (hand or foot first)?

    Do not attempt delivery; cover with sterile dressing; transport. Limb presentations indicate malposition requiring cesarean delivery, so avoid manipulation to prevent cord prolapse or injury.

15. What is the Apgar score timing schedule after birth?

    Assess at 1 minute and 5 minutes after birth. Apgar scores evaluate newborn adaptation at these intervals to identify need for resuscitation and monitor improvement.

16. What is eclampsia and the most critical immediate EMS priority?

    Preeclampsia with seizures; manage airway and prevent injury. Eclampsia is a severe complication of preeclampsia involving convulsions, requiring immediate airway protection to prevent aspiration and trauma.

17. What is the defining finding of a prolapsed umbilical cord?

    Cord presents before the fetus, often visible at the vagina. Prolapse occurs when the cord descends ahead of the fetus, risking compression and fetal hypoxia if not addressed promptly.

18. Which finding most strongly suggests placenta previa in a pregnant patient?

    Painless bright red vaginal bleeding. Placenta previa involves low placental implantation covering the cervix, resulting in painless bleeding from vessel disruption during dilation.

19. Which option best defines the third stage of labor in an obstetric patient?

    Delivery of the newborn to delivery of the placenta. This placental stage follows the baby's birth and involves uterine contractions that separate and expel the placenta to complete the delivery process.

20. Which option best defines the first stage of labor in an obstetric patient?

    Onset of contractions to complete cervical dilation. This stage encompasses the dilation phase, beginning with true labor contractions and ending when the cervix reaches 10 cm dilation to prepare for fetal expulsion.

21. Which option best defines the second stage of labor in an obstetric patient?

    Complete dilation to delivery of the newborn. This expulsion stage starts once the cervix is fully dilated and involves active pushing until the baby is completely delivered from the birth canal.

22. What is the correct action if breech delivery results in the head not delivering promptly?

    Create airway with two fingers in vagina; rapid transport. Creating a vaginal airway facilitates fetal oxygenation when the head is entrapped, with rapid transport needed for surgical delivery.

23. Which finding most strongly suggests abruptio placentae in a pregnant patient?

    Painful vaginal bleeding with uterine tenderness. Abruptio placentae causes placental separation leading to painful bleeding and tenderness due to blood accumulation and uterine irritation.

24. What is the correct manual action during umbilical cord prolapse while awaiting transport?

    Insert gloved hand and lift presenting part off the cord. Manual elevation relieves pressure on the prolapsed cord, preserving umbilical blood flow until definitive care is available.

25. What is the most important initial action when crowning is observed during delivery?

    Support the perineum and control delivery of the head. Supporting the perineum prevents tearing and controls the head's emergence to minimize trauma during the expulsion phase.
