10.A newborn is considered to be "term" if it is born after ____ weeks and before ____ weeks. A.34; 37 B.37; 42 C.38; 44 D.39; 43

B.37; 42 Rationale: A term gestation ranges between 37 and 42 weeks. An infant who is born before 37 weeks' gestation (or weighs less than 5 lb, regardless of gestational age) is considered premature. An infant born after 42 weeks is considered past due.

5.Upon delivery of the baby's head, you note that the umbilical cord is wrapped around its neck. You should: A.immediately clamp and cut the cord. B.make one attempt to slide the cord over the head. C.keep the cord moist and transport as soon as possible. D.give the mother high-flow oxygen and transport rapidly.

B.make one attempt to slide the cord over the head. Rationale: If the umbilical cord is wrapped around the baby's neck (nuchal cord), you should make one attempt to gently remove the cord from around the baby's neck. If this is not possible, the cord should be clamped and cut. Keep the cord moist, administer high-flow oxygen to the mother, and transport at once.

2.A 23-year-old woman, who is 24 weeks pregnant with her first baby, complains of edema to her hands, a headache, and visual disturbances. When you assess her vital signs, you note that her blood pressure is 160/94 mm Hg. She is MOST likely experiencing: A.eclampsia. B.preeclampsia. C.a hypertensive crisis. D.chronic water retention.

B.preeclampsia. Rationale: Preeclampsia—also called pregnancy-induced hypertension—usually develops after the 20th week of gestation and most commonly affects primigravida (first pregnancy) patients. It is characterized by a headache, visual disturbances, edema of the hands and feet, anxiety, and high blood pressure. Preeclampsia can lead to eclampsia, a life-threatening condition that is characterized by seizures.

If a newborn's heart rate is 75 beats/min, what should you do? Keep the newborn warm and assess him or her continuously. Begin assisted ventilation with a bag-mask device and room air. Begin assisted ventilation with a bag-mask device and 100% oxygen. Begin chest compressions.

Begin assisted ventilation with a bag-mask device and room air.

8.The MOST effective way to prevent cardiopulmonary arrest in a newborn is to: A.rapidly increase its body temperature. B.allow it to remain slightly hypothermic. C.ensure adequate oxygenation and ventilation. D.start CPR if the heart rate is less than 100 beats/min.

C.ensure adequate oxygenation and ventilation. Rationale: Cardiopulmonary arrest in infants and children (including newborns) is most often the result of respiratory arrest. Therefore, ensuring adequate oxygenation and ventilation at all times is critical. It is also important to maintain the infant's body temperature and to prevent hypothermia.

4.Immediately after delivery of the infant's head, you should: A.suction the baby's mouth and then nose. B.suction the baby's nose and then mouth. C.assess the baby's breathing effort and skin color. D.check the position of the umbilical cord.

D.check the position of the umbilical cord. Rationale: Immediately following delivery of the infant's head, you should check the position of the umbilical cord to make sure it is not wrapped around the baby's neck (nuchal cord). If a nuchal cord is not present, suction the infant's mouth and nose.

6.The need for and extent of newborn resuscitation is based on: A.the 1-minute Apgar score. B.the gestational age of the newborn. C.the newborn's response to oxygen. D.respiratory effort, heart rate, and color.

D.respiratory effort, heart rate, and color. Rationale: The need for and extent of newborn resuscitation is based on respiratory effort, heart rate, and skin color. The Apgar score is not used to determine if resuscitation is needed; the first score is not assigned until the newborn is 1 minute of age. Resuscitation, if needed, should commence immediately.

Labor is usually longer in a multigravida and shorter in a primigravida. True/False

False

9.While assisting a woman in labor, you visualize her vaginal area and see an arm protruding from her vagina. She tells you that she feels the urge to push. You should: A.cover the arm with a sterile towel and transport immediately. B.encourage her to keep pushing as you prepare for rapid transport. C.insert your gloved fingers into the vagina and try to turn the baby. D.instruct the mother to keep pushing and give her high-flow oxygen.

A.cover the arm with a sterile towel and transport immediately. Rationale: Limb presentations do not deliver in the field—period! If the mother feels the urge to push, instruct her to stop; she should pant instead. Cover the protruding limb with a sterile towel, administer high-flow oxygen to the mother, and transport immediately. Delivery must take place in the hospital.

1.The first stage of labor ends when: A.the presenting part of the baby is visible. B.contractions are less than 10 minutes apart. C.the mother experiences her first contraction. D.the amniotic sac ruptures and labor pains begin.

A.the presenting part of the baby is visible.
