Question 1

What medication prior cardiac catheterization can be given to prevent arrhythmia?

Answer 1

Digoxin

Question 2

r/t List the diseases related to INCREASED PULMONARY BLOOD FLOW.

Acyanotic (L to R shunt), 4

Answer 2

• ASD
• VSD
• PDA
• Atrioventricular Canal

Question 3

Classification of CHD

r/t OBSTRUCTION TO BLOOD FLOW FROM VENTRICLES

Acyanotic, 3

Answer 3

• Coartication of Aorta
• Aortic Stenosis
• Pulmonic Stenosis

Question 4

Classification of CHD

r/t DECREASED PULMONARY BLOOD FLOW

Cyanotic (R to L shunt), 2

Answer 4

• Tetralogy of Fallot
• Tricuspid Atresia

Question 5

Classification of CHD

r/t MIXED BLOOD FLOW

Cyanotic, 4

Answer 5

• Transpotion of Great Arteries
• Total Anamolous Venous Return
• Truncus Arteriosus
• Hypoplastic Left Heart Syndrome

Question 6

What are the clinical manifestation of increased pulmary blood flow?

THink about ASD, VSD, PDA, and atrioventricular canal.

Answer 6

• Tachycardia
• Tachypnea
• Increased Caloric needs
• FTT
• Poor suck/ poor feeding
• Na and fluid retention

Question 7

What is Circumoral Cyanosis? And where are you likely to see this?

Answer 7

Blueness appears in the mouth and lips. Occurs with feeding and crying

Question 8

Pathophysiology of Decreased Pulmoary Blood Flow (Cyanotic)

Answer 8

Blood tends to send from right side to left side because pressure of the right side must increase to get blood to the lungs. Since lungs is not getting enough blood will have a decrease in oxygenated blood circulatinf the body. Right to left shunt.

*TOF and TA

Question 9

Clinical Manidestations of Decreased Pulmonary Blood Flow

Answer 9

• Mild to severe desaturation
• PaO2 50-90%
• Increase in erthropoeiten
• Polycythemaia to compensate for the low O2 levels in the body

Question 10

What causes the overriding aorta in TOF?

Answer 10

VSD is what causes the to aorta to sit between the ventricles instead of only coming out of the left ventricle.

Question 11

Ductal Dependant Pathophysiology of TOF

Answer 11

PDA is to remain open to allow for mixing of blood and ocygenation of the blood to occur especially with sever pulmonic stenosis becaise that makes it hard for blood to get to the lings

Question 12

Pink TET is indiciative to the severity of TOF

Answer 12

Minor

but not under stress

Question 13

CMx of TOF

Describe TET spells - knee to chest squatting

Answer 13

happens when the child has hypoxia and is caused by stress

knee to chest chest squating helps increase cardiac output since lower extremity veins decreases heart rate

Question 14

Tricuspid Atresia

What is Glenn Procedure

Step2 of Treatment

Answer 14

SVC is detached from the heart, then connected to the pulmonary artery

Question 15

Tachycardia, easily fatiqued, mottled skin, gallop rhythm, exercise intolerance, irritable, poor perfusion/ slow cap refill, weak pulses, low BP, extream pallor/duskiness is which clinical manifestation of CHF?

Answer 15

Impaired Myocardial Function

Question 16

Inability to feed, poor weight gain, increased kcal needs, increased metabolic, diaphoresis, hypoxemia/ mild cyanosis, intercostal rtractions, wheezing, dry hacking cough, gasping/grunting describes which clinical manifestations of CHF?

Answer 16

Pulmnary Congestion

Question 17

Heptalomegaly, wt gain (from edema), sodium retention, distended neck veins describes which clinical manifesations of CHF?

Answer 17

Systemic Venous Congestion
