    (this multiple choice question has been scrambled)
  4. As the head of a neonate contaminated with meconium emerges at birth, the heart rate monitor indicates 120 beats/minute, and the physician notices that the infant has good muscle tone and a strong respiratory effort. What should the physician do at this time to provide airway care?

  5. A preterm neonate with a heart rate of 55 beats/minute is receiving positive-pressure ventilation immediately after delivery. What should the therapist do at this time?
    A. Increase the respiratory rate on the ventilator.
    B. Administer medication to increase myocardial contractility and maintain positive ventilation.
    C. Apply cardiac compressions and maintain positive-pressure ventilation.
    D. Defibrillate the infant.
    C. Apply cardiac compressions and maintain positive-pressure ventilation.
    (this multiple choice question has been scrambled)
  6. A term infant is born displaying acrocyanosis. What should the therapist do at this time?
    A. Administer oxygen to the newborn.
    B. Begin resuscitative measures.
    C. Institute positive-pressure mechanical ventilation.
    D. Do nothing, as this condition is often transient.
    D. Do nothing, as this condition is often transient.
    (this multiple choice question has been scrambled)
  7. The therapist has completed a 1-minute Apgar score. The following evaluations were obtained: the infant is pale.
    The heart rate is 90 beats/minute.
    The respiratory effort is irregular.
    Some muscle tone is noted.
    No response to nasal suctioning is found.
    On the basis of these findings, what Apgar score should be assigned to this neonate?
    A.3
    B.1
    C. 2
    D.5
    A.3
    (this multiple choice question has been scrambled)
  8. The therapist, working with a neonate, observes that the newborn has adequate ventilatory efforts and a heart rate of 120 beats/minute. However, at the same time, the infant demonstrates cyanosis of the lips and mucous membranes. What should the therapist do at this time?
    A. Initiate positive-pressure mechanical ventilation.
    B. Perform pharyngeal and tracheal suctioning.
    C. Direct 100% oxygen at a flow of 8 L/minute about one-half inch above the infant’s nose and mouth.
    D. Begin resuscitative efforts.
    C. Direct 100% oxygen at a flow of 8 L/minute about one-half inch above the infant’s nose and mouth.
    (this multiple choice question has been scrambled)
  9. A respiratory therapy supervisor is observing a staff member perform bag—mask ventilation on an infant who is being resuscitated. The supervisor notices that the therapist places his fingers on the anterior margin of the infant’s mandible, and lifts the infant’s face into the mask. What should the supervisor do at this time?
    A. Recommend that the therapist perform endotracheal suctioning.
    B. Recommend that the infant immediately receive endotracheal intubation.
    C. Correct the therapist and have him place his fingers onto the soft tissue under the mandible.
    D. Take no action because the therapist is correctly performing valve—mask ventilation.
    D. Take no action because the therapist is correctly performing valve—mask ventilation.

  10. While performing positive-pressure mechanical ventilation on a neonate, the therapist notices that the infant’s thorax is not displaying bilateral expansion during each inspiration. Auscultation of the chest reveals diminished bilateral breath sounds. The infant’s heart rate is 85 beats/minute and observation demonstrates central cyanosis. Which of the following events may have caused this clinical situation?
    I. Pneumothorax
    II. Poorly positioned or leaking mask
    III. Inappropriately sized endotracheal tube

  11. What appears to be the reason for the infrequent need to administer chest compressions and cardiopulmonary resuscitative drugs to neonates in the delivery rooms?
    A. Manipulation and stimulation of the neonate at birth excite the heart, obviating the need for these interventions.
    B. Labor and delivery room personnel are highly trained and qualified with excellent assessment skills, thus avoiding the need for such actions.
    C. The administration of oxygen to the infant’s airway stimulates the heart.
    D. The delivery of adequate ventilation is the primary factor in effective resuscitation of a neonate.
    D. The delivery of adequate ventilation is the primary factor in effective resuscitation of a neonate.

    D. Three compressions for every 15 breaths
    A. Three compressions for every one breath
    (this multiple choice question has been scrambled)
  13. The therapist has been performing cardiopulmonary resuscitation on a neonate for about 90 seconds, applying ventilation with 100% oxygen and chest compressions. The infant has maintained a spontaneous heat rate of 40 beats/minute. What should the therapist recommend at this time?
    A. Administering epinephrine
    B. Initiating high-frequency ventilation
