RES 204 Final Exam Study Guide Questions With Complete Solutions.

A baby is born at term with a bilateral cleft lip and palate and a very small mandible. She requires positive-pressure ventilation because she is not breathing. You are unable to achieve a seal with bag and mask. Which intervention is indicated? correct answer: Insert a laryngeal mask You are at the resuscitation of a newborn who is gasping and has a heart rate of 60 beats per minute. What is the most important action you can take? correct answer: Provide PPV What size (internal diameter) endotracheal tube should be used to intubate a newborn with an estimated gestational age of 26 weeks (estimated birth weight of 800 g)? correct answer: 2.5 mm Your team attends an emergency cesarean delivery of a term baby because of chorioamnionitis, meconium-stained amniotic fluid, and fetal heart rate decelerations. At delivery, the newborn is term as expected, with very poor tone and he is not breathing (apneic). You quickly perform initial steps, but the newborn is still not breathing. What is the most appropriate next step of resuscitation? correct answer: Start PPV and check HR after 15 seconds During the resuscitation of a newborn, you auscultate the apical pulse and count 10 beats over a 6 second period. What heart rate do you report to your team? correct answer: 100 bpm You are part of a team preparing for the birth of a baby who has meconium-stained fluid and a category III fetal heart rate tracing. A person skilled in endotracheal intubation should be correct answer: present at birth You are at a delivery of a baby born through meconium-stained amniotic fluid, and the baby is not vigorous. What steps should be taken immediately after birth? correct answer: bring baby to radiant warmer for initial steps of newborn care. What is the most effective maneuver to establish spontaneous breathing in a baby that is apneic after initial steps? correct answer: PPV that inflates the lungs A newborn of 34 weeks' gestation is not breathing (apneic) at birth, does not respond to initial steps and requires positive-pressure ventilation. What concentration of oxygen should be used as you begin positive-pressure ventilation? correct answer: 21-30% You have started positive-pressure ventilation for a newborn because her heart rate is low (bradycardia). What is the most important indicator of successful positive-pressure ventilation? correct answer: a rising heart rate A baby requires positive-pressure ventilation because she is not breathing (apneic), but she soon establishes spontaneous respirations and a heart rate over 100 beats per minute. Her oxygen saturation is lower than the target level when in room air, so you provide free-flow oxygen. Which of the following devices cannot reliably deliver free-flow oxygen? correct answer: Mask of self-inflating bag
