Q
  1. You have just delivered a little girl who was born 4 weeks premature. There is no evidence of meconium in the amniotic fluid. After drying, warming, suctioning, positioning, and stimulating the infant, she remains acrocyanotic and is not crying. You should:
    A) determine the newborn’s Apgar score.
    B) begin assisting her ventilations at once.
    C) resuction her mouth for up to 10 seconds.
    D) open her airway and assess respirations.
A

Ans: D

A before B

Q
  1. During your rapid assessment of a newborn’s cardiopulmonary status, you note that its respirations are adequate, you feel 8 pulsations in a 6-second time frame, and the newborn is centrally pink but peripherally cyanotic. The MOST appropriate next action should be to:
    A) provide 30 seconds of tactile stimulation.
    B) administer positive-pressure ventilations.
    C) assess the newborn’s blood glucose level.
    D) give free-flow oxygen by mask at 5 L/min.
A

Ans: B

8 X 10 = 80

0-60 = CPR only after clearing airway, stimulating and 30 seconds of BVM

60-100=BVM only clearing airway, inadequate respiratory effort is seen, and stimulation does not hlep

65
Q
  1. After performing the initial steps of resuscitation, you assess a newborn and note that its respirations are poor and its pulse rate is 50 beats/min. You should:
    A) immediately begin positive-pressure ventilations and chest compressions and then reassess the newborn’s pulse rate in 30 seconds.
    B) begin chest compressions if the heart rate remains below 60 beats/min after 30 seconds of effective positive-pressure ventilation.
    C) begin chest compressions, insert an endotracheal tube, and administer 0.1 to 0.3 mL/kg of epinephrine 1:10,000 down the endotracheal tube.
    D) perform tactile stimulation for 30 seconds, reassess the infant’s respirations and pulse rate, and begin positive-pressure ventilations if there is no improvement.
A

Ans: B

0-60 = 30 seconds of BVM with cleared airway, then Chest compressions for 30 seconds, then epi

60-100=BVM only clearing airway, inadequate respiratory effort is seen, and stimulation does not hlep

66
Q
  1. You are transporting a newborn who requires ongoing ventilatory support and chest compressions for severe bradycardia. Your estimated time of arrival at the hospital is 45 minutes. Air medical transport was unavailable due to severe weather in the vicinity. A peripheral IV line has been established in the antecubital vein and you are in the process of attempting intubation. Approximately 10 seconds into your intubation attempt, the newborn’s heart rate suddenly drops more. You should:
    A) abort the intubation attempt and continue ventilations.
    B) continue the intubation attempt and administer atropine.
    C) administer 0.1 to 0.3 mL/kg of epinephrine rapid IV push.
    D) ensure that chest compressions are of adequate rate and depth.
A

Ans: A

Dont continue intubating if youre the only one in the back of the ambulance and have to BVM to prevent resp faillure

67
Q 
67.  You have been providing bag-mask ventilation to a newborn with a sustained heart rate of 75 beats/min for approximately 5 minutes. The infant's abdomen is markedly distended. Although you are properly trained, your protocols do not allow you to intubate newborns. The MOST appropriate intervention involves:
A)  intubating immediately.
B)  suctioning the oropharynx.
C)  inserting an orogastric tube.
D)  manual gastric decompression.
A

Ans: C

Q
  1. You and your partner are caring for a 5-pound distressed newborn. After providing 30 seconds of effective bag-mask ventilations, the newborn’s heart rate remains below 60 beats/min. You should:
    A) cannulate the umbilical vein and give 0.5 mL of epinephrine.
    B) try tactile stimulation as you continue bag-mask ventilations.
    C) start a peripheral IV line and give 4 mEq of sodium bicarbonate.
    D) continue bag-mask ventilations and initiate chest compressions.

69
Q
  1. During the delivery of a post-term baby, you note the presence of particulate meconium in the amniotic fluid. Your post-delivery assessment of the newborn reveals that it is active, has a strong cry, and has a heart rate of 110 beats/min. You should:
    A) deliver free-flow oxygen at 5 L/min while performing deep oropharyngeal suctioning with a bulb syringe aspirator.
    B) avoid any form of tactile stimulation, perform laryngoscopy, and suction meconium from the trachea with an ET tube.
    C) preoxygenate the newborn with bag-mask ventilations for 30 seconds and then perform endotracheal intubation.
    D) ensure that the infant is warm and dry, administer free-flow oxygen if needed, and provide continuous monitoring.

Q 
70.  Your assessment of a depressed 7-pound newborn reveals tachypnea, pallor, weak peripheral pulses, a heart rate of 120 beats/min, and a blood glucose level of 58 mg/dL. Which of the following interventions will MOST likely cause improvement in this newborn's condition?
A)  0.3 mg of naloxone
B)  32 mL of normal saline
C)  6.5 mL of 10% dextrose
D)  0.06 mg of epinephrine

Q 
71.  An untreated patent ductus arteriosus may cause subsequent development of:
A)  congestive heart failure.
B)  ventricular septal defect.
C)  pulmonary stenosis.
D)  a patent foramen ovale.
A

Ans: A

patent ductus arteriosus = hole in heart

72
Q
  1. When an atrial septal defect is present:
    A) blood flow to the lungs is significantly decreased, which leads to severe hypoxemia.
    B) the heart must push harder to force blood flow past a narrowed aorta, resulting in increased afterload.
    C) deoxygenated blood is able to shift from one atrium to the other and mix with oxygen-rich blood.
    D) blood is allowed to bypass the right ventricle and lungs due to the fetus’s lungs being filled with fluid.
A

Ans: C

atrial septal defect = hole between atrias

73
Q 
73.  Tetralogy of Fallot is a combination of four heart defects, including:
A)  atrial septal defect.
B)  coarctation of the aorta.
C)  tricuspid atresia.
D)  right ventricular hypertrophy.
A

Ans: D

tetralogy of Fallout =
1 Vent septal defect = opening in septum between vents
2 pulmonary stenosis = pulmonic valve near right vent is damaged
3 right vent hypertrophy = results from having to pump harder to achieve same result due to all the excess openings
4 overriding aorta = Aorta connects inbetween right and left vent and onto the vent septal defect

74
Q 
74.  Which of the following congenital defects results in an undersized or absent right ventricle?
A)  Tricuspid atresia
B)  Pulmonary stenosis
C)  Tetralogy of Fallot
D)  Atrial septal defect
A

Ans: A

Tricuspid atresia = no tricuspid valve = no separation from right atria and right ventricle = effectively turns the right atria into the new ventricle since it has the only working valve to prevent back flow

Pulmonary stenosis = no pulmonary valve that the right vent has to push through/keeps in blood in lungs and prevents it from backing into heart.

75
Q
  1. Total anomalous pulmonary venous return is a rare congenital defect in which:
    A) pressure in the lungs causes pulmonary hypertension.
    B) the four pulmonary veins connect to the right atrium.
    C) venous blood mixes with arterial blood in the heart.
    D) blood returns to the lungs after being reoxygenated.
A

Ans: B
