 When does most cardiovascular development occur? | b. Between the fourth and seventh weeks of gestation |
| The function of a patent opening between the left and right atria in a fetus is that it allows: | a. right-to-left blood shunting. |
| At birth which of the following statements is true? a. Systemic resistance and pulmonary resistance fall. b. There is a shift in gas exchange from the placenta to the lung. c. Systemic resistance falls and pulmonary resistance rises. d. Systemic resistance and pulmonary resistance rise | b. There is a shift in gas exchange from the placenta to the lung. |
| When does systemic vascular resistance in infants begin to rise? | Once the placenta is removed from circulation |
| Congenital heart defects that cause acyanotic congestive heart failure usually involve: | left-to-right shunts |
| Congenital heart defects that cause hypoxemia, and therefore cyanosis, usually involve | left-to-right shunts |
| Which congenital heart defects occur in trisomy 13, trisomy 18, and Down syndrome | d. Ventricular septal defect and patent ductus arteriosus |
| An infant has a continuous-machine type of murmur best heard at the left upper sternal border throughout systole and diastole. The infant has a bounding pulse and a thrill on palpation. These clinical findings are consistent with which congenital heart defect? | Patent ductus arteriosus (PDA) |
| An infant has a crescendo-decrescendo systolic ejection murmur located between the second and third intercostal spaces along the left sternal border. There is also a wide fixed splitting of the second heart sound. These clinical findings are consistent with which congenital heart defect? | atrial septal defect |
| An infant has a loud, harsh, holosystolic murmur and systolic thrill that can be detected at the left lower sternal border that radiates to the neck. These clinical findings are consistent with which congenital heart defect? | ventricular septal defect |
| Coarctation of the aorta (COA) may be located: a. | c. between the origin of the aortic arch and the bifurcation of the aorta in the lower abdomen |
| Classic manifestations of a systolic ejection murmur, cyanosis of the lower extremities, and decreased or absent femoral pulse are indicative of an older child with which of the following congenital defects? | d. Postductal aortic coarctation |
| What is the most important clinical manifestation of aortic coarctation in the neonate | CHF |
| 14. Children with tetralogy of Fallot compensate to relieve hypoxic spells by: | squatting |
| 15. The infant diagnosed with a small patent ductus arteriosus (PDA) is likely to present: | asymptomatically |
| The foramen ovale is covered by a flap that creates a check valve allowing blood to flow unidirectionally from the _____ to the _____. | right atrium; left atrium |
| 17. Which of the following is consistent with the cardiac defect of transposition of the great vessels? | The aorta arises from the right ventricle. |
| 18. Which of the following describes total anomalous pulmonary venous return? | Pulmonary venous return is to the right atrium |
| Which heart defect produces a systolic ejection murmur at the right upper sternal border that transmits to the neck and left lower sternal border with an occasional ejection click? | c. Aortic stenosis |
| 20. Which heart defect produces a systolic ejection click at the upper left sternal border with a thrill palpated at the upper left sternal border | pulomin stenosis |
| Which heart defect results in a single vessel arising from both ventricles providing blood to both the pulmonary and systemic circulations? | d. Truncus arteriosus |
