  • 2. 

    If the fetal blood flow pattern continues following birth, oxygenation is difficult for the neonate.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    If the fetal blood flow pattern continues following birth, it means that the blood is still flowing in the same way it did when the baby was in the womb. This can lead to difficulties in oxygenation for the neonate because the blood flow pattern in the womb is designed to provide oxygen to the fetus through the placenta. After birth, the baby needs to transition to breathing air and receiving oxygen through the lungs. If the fetal blood flow pattern continues, it can impede this transition and make it difficult for the neonate to receive adequate oxygenation.

    Placement of an umbilical artery catheter (UAC) should be considered to provide continuous BP monitoring and access for arterial blood gases.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Placement of an umbilical artery catheter (UAC) is recommended because it allows for continuous blood pressure monitoring and access for arterial blood gases. This is important in neonatal care as it helps healthcare professionals to closely monitor the blood pressure levels and assess the oxygenation and acid-base balance of the baby. By having a UAC in place, healthcare providers can quickly and easily obtain arterial blood samples for analysis and make informed decisions regarding the baby's treatment and management.

    Rate this question:

  • 4. 

    The main goal in the management of PpHN is correction of asphyxia and acidosis.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The management of Persistent Pulmonary Hypertension of the Newborn (PPHN) primarily focuses on correcting asphyxia and acidosis. Asphyxia refers to a lack of oxygen, which can lead to respiratory distress in newborns. Acidosis refers to an imbalance in the body's pH levels, which can occur due to the accumulation of acid. By addressing these two issues, healthcare professionals can improve the newborn's oxygenation and restore normal pH levels, thereby managing PPHN effectively.

    Rate this question:

  • 5. 

    Oxygen is a potent vasodilator and should be considered a first line drug in the management of PpHN.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Oxygen is considered a first-line drug in the management of PPHN because it acts as a potent vasodilator. This means that it helps to relax and widen the blood vessels, improving blood flow and oxygen delivery to the body's tissues. In the case of PPHN (Persistent Pulmonary Hypertension of the Newborn), there is increased resistance in the blood vessels of the lungs, leading to inadequate oxygenation. Providing oxygen therapy helps to alleviate this condition and improve the baby's oxygen levels, making it an essential and effective treatment option.

    Rate this question:

  • 6. 

    Air leaks and bronchopulmonary dysplasia (BPD) are possible sequelae to PpHN.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Air leaks and bronchopulmonary dysplasia (BPD) are possible sequelae to PPHN, which stands for Persistent Pulmonary Hypertension of the Newborn. PPHN is a condition where the newborn's blood vessels in the lungs do not expand properly after birth, leading to poor oxygenation. This can result in increased pressure in the pulmonary artery and can cause air leaks, where air escapes from the lungs and enters the chest cavity. BPD, on the other hand, is a chronic lung disease that can develop in premature infants or those with respiratory distress syndrome, including those with PPHN. Therefore, it is true that air leaks and BPD can be potential consequences of PPHN.

    Rate this question:

  • 7. 

    The ________________ is the pathway between the pumonary artery and aorta and allows blood to bypass pulmonary circulation.

    • Ductus venosus

    • Foramen ovale

    • Ductus arteriosus

    • Ductus hepaticus

    Correct Answer
    A. Ductus arteriosus
    Explanation
    The correct answer is Ductus arteriosus. The ductus arteriosus is a blood vessel that connects the pulmonary artery to the aorta in a developing fetus. It allows blood to bypass the lungs, as the fetus obtains oxygen from the mother's blood rather than breathing air. After birth, the ductus arteriosus usually closes within a few days or weeks, redirecting blood flow to the lungs for oxygenation. However, in some cases, the ductus arteriosus may remain open, causing a condition called patent ductus arteriosus (PDA), which requires medical intervention.

    Rate this question:

  • 8. 

    Birth marks the beginning of pulmonary-based blood flow.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Birth marks the beginning of pulmonary-based blood flow because before birth, the fetus receives oxygen from the mother's placenta through the umbilical cord. However, once the baby is born, it takes its first breath, and the lungs expand. This triggers a series of changes in the cardiovascular system, including the closure of fetal shunts and the opening of the pulmonary blood vessels. As a result, the blood flow shifts from being primarily directed to the placenta to being directed to the lungs for oxygenation. Therefore, birth is indeed the beginning of pulmonary-based blood flow.

  • 9. 

    PpHN is most commonly seen in -

    • Post-term infant

    • Term infant

    • Term infant with aspiration syndrome

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    PPHN stands for Persistent Pulmonary Hypertension of the Newborn, which is a life-threatening condition characterized by high blood pressure in the lungs. It occurs when the normal transition of blood circulation in the newborn fails to happen. PPHN can be seen in post-term infants, who are born after 42 weeks of gestation, as well as term infants and term infants with aspiration syndrome. Therefore, the correct answer is "All of the above" because PPHN can occur in all of these scenarios.

    Rate this question:

  • 10. 

    The _______________ is located in the septum between the atria and allows the blood to bypass pulmonary circulation.

    • Ductus venosus

    • Foramen ovale

    • Ductus arteriosus

    • Ductus hepaticus

    Correct Answer
    A. Foramen ovale
    Explanation
    The foramen ovale is located in the septum between the atria and allows the blood to bypass pulmonary circulation. This is a small opening that exists in the fetal heart, allowing oxygenated blood from the placenta to flow directly from the right atrium to the left atrium, bypassing the lungs. This is necessary in the fetal stage as the lungs are not yet fully developed and do not perform their usual function of oxygenating the blood. After birth, the foramen ovale typically closes and becomes a depression known as the fossa ovalis.

    A sedative to consider using for the infant with PpHN is -

    • Fentanyl

    • Morphine sulphate

    • Phenobarbital

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the above medications, Fentanyl, Morphine sulfate, and Phenobarbital, can be considered as sedatives for infants with PPHN (Persistent Pulmonary Hypertension of the Newborn). PPHN is a condition where the newborn's blood vessels in the lungs do not expand properly, leading to low oxygen levels. Sedatives can help relax the infant and reduce their respiratory distress. Fentanyl and Morphine sulfate are opioids that can provide pain relief and sedation, while Phenobarbital is a barbiturate that can induce sedation and decrease neuronal activity. Using all of these medications together or individually can be effective in managing PPHN in infants.

    The following questions are the activity evaluation. Discuss the transition from fetal cardiopulmonary blood flow to adult blood flow pattern.

    • Excellent

    • Good

    • Fair

    • Poor

    Correct Answer
    A. Excellent
    Explanation
    The transition from fetal cardiopulmonary blood flow to adult blood flow pattern refers to the changes that occur in the circulation of blood in the heart and lungs as a fetus develops into an adult. During fetal development, blood flow bypasses the lungs through the ductus arteriosus and foramen ovale. After birth, these structures close and blood flow is redirected to the lungs for oxygenation. The transition from fetal to adult blood flow pattern is a complex process that ensures proper oxygenation of blood and is essential for the survival and development of the individual. The answer "Excellent" indicates a thorough and accurate understanding of this transition.

    Rate this question:

  • 16. 

    The most important transition event that occurs with birth is -

    • Pulmonary vascular resitance increases

    • Systemic vascular resistance decreases

    • The ductus arteriosus closes

    • Effective respirations and ventilation are established

    Correct Answer
    A. Effective respirations and ventilation are established
    Explanation
    Effective respirations and ventilation are established as the most important transition event that occurs with birth. This is because when a baby is born, they transition from receiving oxygen through the placenta to breathing on their own. The establishment of effective respirations and ventilation ensures that the baby can adequately exchange oxygen and carbon dioxide, allowing them to sustain life outside the womb. This transition is crucial for the baby's survival and adaptation to the extrauterine environment.

  • 19. 

    For the following question, check all answer(s) that apply. PpHN may be caused by -

    • Muscularization of the pulmonary blood vessels

    • Congenital heart defects

    • Neonatal sepsis

    • Hypothermia and hypoglycemia

    Correct Answer(s)
    A. Muscularization of the pulmonary blood vessels
    A. Congenital heart defects
    A. Neonatal sepsis
    A. Hypothermia and hypoglycemia
    Explanation
    PPHN, or Persistent Pulmonary Hypertension of the Newborn, is a condition characterized by high blood pressure in the blood vessels of the lungs. It can be caused by various factors, including muscularization of the pulmonary blood vessels, congenital heart defects, neonatal sepsis, and hypothermia and hypoglycemia. Muscularization of the pulmonary blood vessels refers to the abnormal thickening of the blood vessel walls, which can restrict blood flow and increase blood pressure. Congenital heart defects can also lead to PPHN by affecting the normal circulation of blood. Neonatal sepsis, a severe infection in newborns, can cause inflammation and damage to the blood vessels. Additionally, hypothermia (low body temperature) and hypoglycemia (low blood sugar) can contribute to the development of PPHN.
