AEMCA - Advanced Emergency Medical Care Assistant Obstetrics and Neonatology Questions and Answers — Questions and Answers
Question 1: You are called to a 34-year-old female, G3P2 at 38 weeks gestation, whose membranes have just ruptured. During assessment, you visualize the umbilical cord protruding from the vagina. The patient is anxious and states she feels contractions. What is the most critical immediate intervention?
- Administer high-flow oxygen and initiate rapid transport.
- Attempt to gently push the cord back into the vaginal canal.
- Place the patient in a knee-chest position and manually elevate the presenting fetal part. (Correct answer)
- Encourage the patient to push forcefully with her next contraction to expedite delivery.
Correct answer: Place the patient in a knee-chest position and manually elevate the presenting fetal part.
Umbilical cord prolapse is a true obstetrical emergency where the cord is compressed between the presenting part and the maternal pelvis, cutting off oxygen to the fetus. The single most important intervention is to relieve this pressure. This is achieved by placing the mother in a knee-chest or exaggerated Sims' position and inserting a sterile gloved hand into the vagina to manually lift the presenting part off the cord. Pushing the cord back in is not recommended and can cause vasospasm. While oxygen and transport are necessary, they are not the first critical action to relieve the life-threatening compression.
Question 2: A 29-year-old in her third trimester of pregnancy presents with sudden, painless, bright red vaginal bleeding. Her abdomen is soft and non-tender on palpation. Which of the following conditions is most likely?
- Placental abruption
- Uterine rupture
- Placenta previa (Correct answer)
- Braxton Hicks contractions
Correct answer: Placenta previa
The classic presentation of placenta previa is painless, bright red vaginal bleeding in the second or third trimester. The uterus is typically soft and non-tender. In contrast, placental abruption usually presents with dark red bleeding, significant abdominal pain, and a rigid, tender uterus. Uterine rupture involves excruciating pain and signs of shock, while Braxton Hicks contractions do not cause significant bleeding.
Question 3: Following a field delivery of a vigorous, crying newborn at term, what are the appropriate initial steps of neonatal care?
- Immediately clamp and cut the umbilical cord, then begin chest compressions.
- Provide positive pressure ventilation, check a blood glucose level, and apply a pulse oximeter.
- Administer blow-by oxygen, perform deep suctioning of the oropharynx, and wrap the infant in a dry blanket.
- Dry the infant, provide warmth with skin-to-skin contact, clear the airway only if necessary, and stimulate breathing. (Correct answer)
Correct answer: Dry the infant, provide warmth with skin-to-skin contact, clear the airway only if necessary, and stimulate breathing.
For a vigorous newborn (good muscle tone, strong cry, term gestation), the initial steps focus on routine care to support the transition. This includes providing warmth (placing skin-to-skin with the mother is ideal), drying the infant to prevent heat loss, which also provides stimulation, and positioning the head to ensure an open airway. Suctioning is only indicated if there are signs of airway obstruction. Immediate cord clamping, PPV, and chest compressions are reserved for non-vigorous infants requiring resuscitation.
Question 4: When assessing a newborn's APGAR score, how is respiratory effort evaluated and scored?
- A score of 2 is given for a heart rate over 100 bpm.
- A score of 1 is given for a slow or irregular cry; a score of 2 is for a vigorous cry. (Correct answer)
- A score of 0 is for acrocyanosis; a score of 2 is for a completely pink body.
- A score of 1 is for no response to stimulation; a score of 2 is for a grimace.
Correct answer: A score of 1 is given for a slow or irregular cry; a score of 2 is for a vigorous cry.
The 'Respiration' component of the APGAR score is assessed based on the infant's breathing effort. A score of 0 is given for absent respirations (apnea). A score of 1 is for slow, weak, or irregular respirations. A score of 2 is awarded for a strong, vigorous cry. The other options describe the scoring for Heart Rate, Appearance (Color), and Reflex Irritability (Grimace), respectively.
Question 5: You have just assisted with a delivery in the patient's home. The placenta has delivered, but the mother is now experiencing heavy vaginal bleeding and the uterine fundus feels soft and 'boggy'. What is the primary and most important prehospital intervention for this condition?
- Administer high-flow oxygen.
- Initiate IV access and administer a 500 mL fluid bolus.
- Firmly massage the uterine fundus. (Correct answer)
- Place the patient in the Trendelenburg position.
Correct answer: Firmly massage the uterine fundus.
The patient's signs and symptoms are classic for uterine atony, the most common cause of postpartum hemorrhage (PPH). The primary, most effective, and immediate prehospital intervention is to perform a firm fundal massage. This action mechanically stimulates the uterus to contract, which constricts the blood vessels at the placental site and controls the bleeding. While oxygen, IV fluids, and positioning are important supportive measures, they do not address the underlying cause as directly as fundal massage.
Question 6: Which of the following is an absolute contraindication for administering oxytocin in the management of postpartum hemorrhage?
- The mother is breastfeeding.
- The placenta has not yet been delivered. (Correct answer)
- The patient has a history of Cesarean section.
- The patient received an epidural during labor.
Correct answer: The placenta has not yet been delivered.
Oxytocin is a uterotonic agent used to cause uterine contraction to control postpartum hemorrhage. It should only be administered AFTER the delivery of the placenta. Administering it before the placenta delivers can cause the cervix to contract and close, leading to a retained placenta, which can worsen bleeding and cause other complications. None of the other options are contraindications for the use of oxytocin in the management of PPH.
