Select one:
a. a yellow or orange tint to the white portion of the eyes.
b. spontaneous bleeding due to blood-clotting abnormalities.
c. an inability to shiver due to an immature immune system.
d. hardening of the skin associated with reddening and edema.
d. hardening of the skin associated with reddening and edema.
The quickest way to prevent newborn hypothermia involves:
Select one:
a. administering warmed IV fluids.
b. thoroughly drying the newborn after birth.
c. applying a hot water bottle to the groin area.
d. administering warmed, humidified oxygen.
b. thoroughly drying the newborn after birth.
An untreated patent ductus arteriosus may cause subsequent development of:
Select one:
a. congestive heart failure.
b. ventricular septal defect.
c. pulmonary stenosis. Incorrect
d. a patent foramen ovale.
a. congestive heart failure.
When an atrial septal defect is present:
Select one:
a. blood flow to the lungs is significantly decreased, which leads to severe hypoxemia.
b. the heart must push harder to force blood flow past a narrowed aorta, resulting in increased afterload.
c. deoxygenated blood is able to shift from one atrium to the other and mix with oxygen-rich blood.
d. blood is allowed to bypass the right ventricle and lungs due to the fetus’s lungs being filled with fluid.
c. deoxygenated blood is able to shift from one atrium to the other and mix with oxygen-rich blood.
Tetralogy of Fallot is a combination of four heart defects, including:
Select one:
a. atrial septal defect.
b. coarctation of the aorta.
c. tricuspid atresia.
d. right ventricular hypertrophy.
d. right ventricular hypertrophy.
Which of the following congenital defects results in an undersized or absent right ventricle?
Select one:
a. Tricuspid atresia
b. Pulmonary stenosis
c. Tetralogy of Fallot
d. Atrial septal defect
a. Triscupid atresia
Total anomalous pulmonary venous return is a rare congenital defect in which:
Select one:
a. pressure in the lungs causes pulmonary hypertension.
b. the four pulmonary veins connect to the right atrium.
c. venous blood mixes with arterial blood in the heart.
d. blood returns to the lungs after being reoxygenated.
b. the four pulmonary veins connect to the right atrium.
Clinical Presentation: includes increasing respiratory rate and effort; increasing heart rate, bounding pulses in the upper extremities with thready or absent pulses in the lower extremities and fatigue at feedings. Which congenital heart disease is being described?
