3.Answer: A.If the newborn’s pulse rate remains below 60 beats/min following 30 seconds of positive-pressure ventilation via a bag-mask device. Rationale: Unlike adults and children, the resuscitation of newborns begins with providing positive-pressure ventilations via a bag-mask device for 30 seconds. If the pulse rate does not increase above 60 beats/min after 30 seconds of positive-pressure ventilations, then chest compressions should be started and positive-pressure ventilations continued. 4.Answer: C.One third the anteroposterior diameter of the chest Rationale: 2010 American Heart Association guidelines for neonatal resuscitation state that the appropriate depth of compressions is one third the diameter of the chest. 5.Answer: C.3:1

Rationale: There should be a 3:1 ratio of compressions to ventilations with 90 compressions and 30 breaths being delivered each minute. This equals 120 events per minute. 6.Answer: B.0.1 to 0.3 mL/kg; 1:10,000 Rationale: The appropriate dose of epinephrine for neonatal resuscitation via the IV route is 0.1 to 0.3 mL/kg of 1:10,000 epinephrine, best administered via the umbilical vein, or 0.01 to 0.03 mg/kg of 1:10,000 epinephrine. The appropriate dose of epinephrine for neonatal resuscitation via the ET route is three times that of IV administration, 0.3 to 1 mL/kg of 1:10,000 epinephrine. 7.Answer: A.ventilatory support. Rationale: Newborns are transitioning to lung breathing; therefore, inflation of the lungs is the most important measure. The most important and effective action in neonatal resuscitation is to ventilate the newborn’s lungs. Lack of ventilation results in sustained constriction of the pulmonary arterioles, preventing systemic arterial blood from becoming oxygenated. When a fetus or newborn first becomes deprived of oxygen, an initial period of attempted rapid breathing is followed by primary apnea and a dropping pulse rate that will improve with tactile stimulation. If oxygen deprivation continues, secondary apnea ensues accompanied by a continued fall in pulse rate and blood pressure. Secondary apnea cannot be reversed with stimulation; assisted ventilation must be provided. Initiation of effective positive-pressure ventilation during secondary apnea usually results in a rapid improvement in heart rate. Additional Questions 8.Rationale: Several things can lead to premature delivery and unfortunately, most of them are beyond the control of the woman. Risk factors include genetic abnormalities, infection, early opening of the cervix (cervical incompetence), placental abruption, multiple gestation, past history of a premature delivery, smoking, and trauma. Assignments A.Review all materials from this lesson and be prepared for a lesson quiz to be administered (date to be determined by instructor). B.Read Chapter 43, Pediatric Emergencies, for the next class session. Unit Assessment Keyed for Instructors 1.What is the difference between a newborn and a neonate?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
