Test 2 (Mod 3 and 4) Flashcards
Four Heart Valves are
Tricuspid, Pulmonic, Mitral, Aortic
Tricuspid Valve links
Right atrium to right ventricle
Pulmonic Valve links
Right ventricle to pulmonary artery
Mitral Valve links
Left atrium to left ventricle
Aortic Valve links
Left ventricle to aorta
Umbilical Vein carries oxygenated blood from
Placenta to infant
In fetal circulation, blood bypasses the liver through the
Ductus Venosus
In fetal circulation, oxygenated blood flows from right to left atria through the
Foramen Ovale
Closes after birth with change in pressure in cardiac chambers
Foramen Ovale
Causes fetal circulation blood to bypass the lungs, which are nonfunctional at this time
Foramen Ovale
A fistula between aorta and pulmonary artery that allows for mixing of blood
Ductus Arteriosus
Closes after birth, sometimes with first few breaths but may take up to three days
Ductus Arteriosus
Bound to hemoglobin on red blood cells
Oxygen
Facilitate Oxygen
Hematocrit and hemoglobin
Heart rate is sensitive to
Oxygen level
Cardiac output is dependent on ________ until child is 5 years old
Heart rate
A child has an increased risk of heart failure because of
Immature heart that is sensitive to volume or pressure overload, and muscle fibers that are less developed
Reveals size and contour of heart
X-ray
Visualizes characteristics of pulmonary vascular markings
X-ray
Identifies heart structure
Ultrasound (Echocardiography)
Identifies pattern of movement, hemodynamics
Ultrasound (Echocardiography)
Records quality of major electrical activity of heart
Electrocardiogram (ECG)
Identifies dysrhythmias
Electrocardiogram (ECG)
Encourage increased fluid intake to maintain hydration to offset diuretic effect of contrast dye after
Cardiac Catheterization
