Exam Preview for 2058: Understanding Neonatal Cardiac Defects: Insi

Understanding Neonatal Cardiac Defects: Insights from a Respiratory Therapy Perspective

Please note: exam questions are subject to change.

1. In normal anatomy, which of the following statements about systemic vascular resistance (SVR) is true? SVR is low SVR is high SVR is equal to pulmonary vascular resistance SVR varies depending on the age
2. Why does the patent ductus arteriosus (PDA) predominantly shunt left to right? Pulmonary vascular resistance (PVR) is greater than systemic vascular resistance (SVR) PVR and SVR are equal PVR and SVR do not affect the direction of shunting PVR is less than SVR
3. How might a patient with coarctation of the aorta present in terms of heart-related symptoms? Palpitations and fatigue Chest pain and dizziness Murmurs and congestive heart failure High blood pressure and warmth in the lower extremities
4. What complication can arise from an interrupted aortic arch with the presence of a ventricular septal defect (VSD)? Left heart failure Right heart failure Pulmonary hypertension Congestive right heart failure
5. During a hemi-Fontan procedure, what change is made in the circulatory pathway? Superior vena cava (SVC) connected directly to the pulmonary artery Pulmonary artery connected directly to the aorta Inferior vena cava (IVC) connected directly to the aorta Pulmonary artery connected directly to the superior vena cava
