Cardiac Flashcards
(44 cards)
stenosis
narrowing causing obstruction to blood flow
Atresia
Complete blockage of blood flow
heart murmurs
abnormal struture of the heart, making blood travel in an abnormal fashion resulting in noise
Physical indicators of cardiac dysfunction
Tachypnea, tachycardia, diaphoresis, crackles, edema, cyanosis, murmur, sternal lift, clubbing of the fingers
Normal heart rate:
- Newborn
- 3 Years
- 10 years
- 16 years
- 120-160
- 80-125
- 70-120
- 55-90
Cardiac catherization
Invasive routine and diagnostic procedure using radiopaque catheters placed in peripheral blood vessel and then guided into heart with aid of fluoroscopy
Biggest risks of cardiac cath
BLEEDING
Cardiac cath post op care includes:
Check pulses
Monitor coolness, blanching
Vitals taken every 15 minutes, HR for full 60 seconds
Hypotension could indicate hemorrhage
Fluid intake, blood glucose levels
What do you do if bleeding occurs after a cardiac cath?
Direct continuous pressure is applied 1 inch above the site to localized pressure of the vessel puncture
What do you do before giving digoxin?
Check apical pulse for a full 60 seconds prior to administration
What pulse would indicate not to give digoxin?
- Infants?
- Older children
90 -110 bpm in infants
70 beats/min in older children
Signs of toxicity in digoxin
N/V
Anorexia
Bradycardia
Dysrhythmias
Prostaglandins - IMPORTANT TO KNOW!
Metabbolizes rapidly - infusion must be continuous and have it’s own IV line
Side effects of prostaglandins
Reduced glomerular filtration
Impaired Plt function
Decreased GI blood flow
What is the major cause of death in the first year of life?
Congenital Heart Disease
Left to Right Shunting
Involves blood flow from the left side(blood that goes to the body) of heart to the right side(blood that goes to the lungs) resulting in increased pulmonary blood flow
Ventricular septal defect(VSD)
MOST COMMON
- Abnormal opening is present in the septum between the two ventricles
Allows blood to shunt L-R
Blood that should go to aorta and out of the body shunts back into pulmonary circulation
VSD assessment upon child
occurs when 4-8 years old
Fatigue, loud and harsh murmur
- SOB, crackles, feeding difficulty, murmur, FTT. respiratory infections, cardiomegaly
- Fatigue, Harsh murmur(at 4-8 weeks of life) is when shunting starts
Treatment of VSD
Most close spontaneously by age of 1
Cardiac cath: moderate size
Prophylatic abx 6 mos - prevents endo carditis and other infections before/after surgery
When would you perform open heart surgery for a patient with VSD?
Over 3mm
-age of 2
Nursing interventions of VSD:
Monitor feeding - give breaks during
S/S CHF
Monitor WOB
Medication for VSD
-Diuretic or digoxin - prevent fluid accumulation in lungs
Atrial Septal Defect(ASD)
- abnormal opening between the atria that causes an increased flow of oygenated blood into the right side of the heart
- Blood shifts L to R
- Most common in girls
How will a patient present with ASD?
Asymptomatic until infection from recirculating blood occurs
