Peds Test 3

Chapters 30, 33, 34, 35

TermDefinition
Ventricular Septal Defect (VSD): A hole in the septum between the right and left ventricle that results in INCREASED pulmonary blood flow (left-to-right shunt) Manifestations: loud, harsh murmur that is not usually audible until pulmonary pressures drop at about 4-8 weeks of age -HF -Failure to thrive -small, possibly asymptomatic defects
Ventricular Septal Defect (VSD): A hole in the septum between the right and left ventricle that results in INCREASED pulmonary blood flow (left-to-right shunt) Manifestations: loud, harsh murmur that is not usually audible until pulmonary pressures drop at about 4-8 weeks of age -HF -Failure to thrive -small, possibly asymptomatic defects
Atrial Septal Defect (ASD)- a hole in the septum b/t the right and left atria that results in INCREASED pulmonary blood flow (left-to-right shunt) Manifestations: loud harsh murmur -mild HF -possible enlarged RA -increased O2 Sats in RA -asymptomatic (possibly)
Patent Ductus Arteriosus (PDA)- a condition in which the normal fetal circulation conduit b/t the pulmonary artery and the aorta fails to close and results in INCREASED pulmonary blood flow (left-to-right shunt) Manifestations: murmur (machine hum) -wide pulse pressure -bounding pulses -asymptomatic (possibly)
Pulmonary Stenosis- a narrowing of the pulmonary valve or pulmonary artery that results in obstruction of blood flow from the ventricles Manifestions: systolic ejection murmur -RV enlargement -exercise intolerance -cyanosis w/severe narrowing
Aortic Stenosis- a narrowing at, above, or below the aortic valve Manifestions: murmur -LV enlargement -Chest pain; exercise intolerance; weak, thready pulses; hypotension; dizziness, and syncope
Coarction of the Aorta- a narrowing of the lumen of the aorta, usually at or near the ductus arteriosus, that results in obstruction of blood flow from the ventricles Manifestations: increased blood pressure and O2 sat in the upper extremities compared to the lower extremities -nosebleeds -H/A, vertigo, leg pain, weak or absent lower extremity pulses (indicate decreased CO)
Transposition of the great arteries- a condition in which the aorta is connected to the right ventricle instead of the left, and the pulmonary artery is connected to the left ventricle instead of the right Manifestations: murmur -severe cyanosis appearing hours to days after birth (as the PDA closes) -cardiomegaly -HF
Tricuspid Atresia- a complete closure of the tricuspid valve that results in mixed blood flow Manifestations: no bloodflow from the RA to the RV -severe cyanosis w/in hours of birth (increased as PDA closes) -HF -chronic hypoxemia -failure to thrive and growth retardation
Tetralogy of Fallot- Four defects that result in MIXED blood flow -pulmonary stenosis -ventricular septal defect -overriding aorta -RV hypertrophy Manifestations: murmur -cyanosis, severe dyspnea, clubbing of the fingers, hypercyanotic spells, and acidosis -polycythemia, clot formation -child frequently assuming squatting position (decrease venous return) -failure to thrive and growth retardatio
Right sided HF Right side usually unable to pump blood and increased pressure in RA increasing systemic venous circulation (s&sx= edema, hepatosplenomegaly)
Left sided HF Left side is unable to pump causing increased pressure in Left atrium and pulmonary vein and lungs become edematous and congested increasing pressure
what is the number 1 earliest sign of CHF in children? Tachycardia
when do you hold Digoxin for babies and kids? pulse <90 on babies pulse <70 on kids
What are the 4 classifications of hemodynamic characteristics of CHD? -increased pulmonary blood flow -decreased pulmonary blood flow -obstruction of blood flow from heart -mixed blood flow
All defects with INCREASED pulmonary blood flow? -atrial septal -ventricular septal -atrioventricular canal -patent ductus arteriosus (PDA)
All defects with OBSTRUCTION of blood flow from heart? -coarction of the aorta -aortic stenosis -Pulmonic stenosis
All defects with DECREASED pulmonary blood flow? -tetralogy of fallout - tricuspid atresia
All defects with MIXED blood flow? -transposition of great vessels -total anomalous pulmonary venous connection -Hypoplastic heart syndrome (left, right)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
