Q

what side of the heart has more pressure

A

left side
if there is a hole then more blood will flow into the right side which just receives blood and sends it into the lungs causing less oxygenated blood going to the body & lots of blood to the lungs

Q

nursing considerations for CHF: prevention of infection

A

-avoid crowded public places
-good hand washing
-screen visitors

24
Q

nursing considerations for CHF: fluid volume excess

A

-I&Os
-daily wts w/ everything the same
-assess for edema
-maintain fluid restriction if ordered
-provide skin care
-change position frequently

25
Q

family education & support for a child w/ CHF or

A

-vaccines
-promote G&D
-make sure they know how to give meds

26
Q

increased pulmonary blood flow: arterial septal defect

A

know there is a hole between the atrium & more blood on right side
-may be asym, hear a murmur, CHF & increased risk for dysrhythmias
-usually resolves on own or surgery

27
Q

increased pulmonary blood flow: ventricular septal defect

A

More series than ASD
the septum fails to completely form between the right & left ventricles

28
Q

increased pulmonary blood flow: patent ductus arteriosus

A

the fetal structure fails to close, blood is shunted from the aorta to the pulmonary artery blood is going to lungs not body

29
Q

PDA treatments

A

-indomethacin (prostaglandin E inhibitor)
-interventional heart cath w/ coil
-left thoracotomy or VATS (3 small incisions on left side of chest to place a clip on the ductus)

29
Q

with a coarctation of the aorta, what exterminates will been more effect and symptoms

A

the lower exterminates bc the structure is past the branches of the aorta that go to your head
may be increased blood flow to upper causing headaches, nose bleeds, bounding pulses

30
Q

obstruction of blood flow: coarctation of the aorta

A

a narrowing of the aortic arch, usually distal to the ductus arteriosus and beyond the right subclavian artery

31
Q

obstruction of blood flow: aortic stenosis

A

narrowing or fusion of aortic valves which interfers with left ventricle outflow. blood backs up into right side of heart and right side of heart enlarges
results in decreased cardiac output, LVH & pulmonary vascular congestion

32
Q

obstruction of blood flow: pulmonic stenosis

A

defect involves narrowing or constriction of valves of the pulmonary artery interfering w/ right outflow

33
Q

cyanotic defects & symptoms

A

caused by defects result in decreased pulmonary blood flow causing cyanosis, polycythemia (thick blood), digital clubbing & altered ABGs
pressure greater on pulmonic side so blood shunts from right to left

34
Q

nursing considerations for cyanotic defects

A

-prevent polycythemia to avoid clots & assess for clots
-do not let child get dehydrated
-good skin care
-oxygen
-prep for procedures

35
Q

decreased pulmonary blood flow: tetralogy of fallot

A

4 parts
1) palmonic stenosis
2) overriding aortic arch (aorta is over the middle of heart & not over the left ventricle)
3) VSD
4) right ventricular hypertrophy (ventricle becomes smaller bc muscle thickens)

36
Q

what position do we usually see children in who have tetralogy of fallot and why

A

squatting position

37
Q

guidelines for hypercyanotic spell

A

employ calm, comforting approach
-knee to chest position
-100% oxygen by face mask
-give morphine
-IV fluid replacement & volume expansion if needed
-repeat morphine if needed
be able to list, do this one at a time and only continue if needed

38
Q

decreased pulmonary blood flow: tricuspid atresia

A

failure of the tricuspid valve to develop resulting in no communication between right atrium and ventricle resulting in severe right hypoplasia or absense of the right ventricle

39
Q

how do you keep the foramen ovale open

A

give prostaglandin E to maintain foreman ovale need open for mixing of blood, will result in death if not then digoxin, diuretics & palliative surgery will help

40
Q

mixed blood flow: transposition of the great arteries

A

pulmonary artery arises from left ventricle and the aorta arises from the right ventricle. No communication between the systemic & pulmonary circulations
the artery & aorta are switched

41
Q

mixed blood flow: truncus arteriosus

A

pulmonary artery and aorta fail to divide during embryonic development. one single large vessel empties both ventricles

42
Q

truncus arteriosus clinical manifestations

A

-cyanosis
-CHF
-heart murmur

43
Q

mixed blood flow: hypoplastic left heart syndrome

A

aortic valve atresia, mitral atresia or stenosis, small or absent left ventricle, severe hypoplasia of the ascending aorta and aortic arch
very sick & usually ends in death

44
Q

discharge planning post cardiac cath

A

-pressure dressing x24 hr
-no tub baths for 48hrs
-rest 1 night then can resume activities
-teach S/s of infections

45
Q

how do the fetal shunts close at or shortly after birth

A

-decreased maternal hormone prostaglandin E
-increased O2 sat
-pressure changes within the heart

46
Q

clinical manifestations of VSD

A

-CHF & cyanosis
-murmur
-right vent hypertrophy
-FTT
-fatigue
-res infections

47
Q

treatment of VSD

A

able to patch it or more intense surgery

48
Q

therapeutic mgt of VSD

A

-pulmonary artery banding
-may close on own by 3yr
-interventional heart cath w/ septal occluder or
-surgical correct w/ patch

49
Q

therapeutic mgt of coarctation of the aorta

A

-prostaglandin E to maintain PDA
-balloon angioplasty
-surgery within the first 2 years

50
Q

aortic stenosis serious side effect

A

-obstruction tends to be progressive
-sudden episodes of MI or low cardiac output, can result in sudden death
activity is limited but not bed rest

51
Q

how to treat aortic stenosis

A

try to fix the valve w/ surgery

52
Q

clinical manifestations of tetralogy of fallot

A

the kids are very sick
-murmur w/ thrill
-polycythemia
-hypoxic episodes
-metabolic acidosis
-poor growth
-clubbing
-exercise intolerance

53
Q

treatment for tetralogy of fallot

A

multiple rounds of surgery

54
Q

treatment for transposition of great vessels

A

once we discover d/t cyanotic spell, we will give prostaglandin E to keep the foramen ovale open until they can have surgery to switch the artery and the aorta

55
Q

treatment of truncus arteriosus

A

-surgical repair during the first few months of life
-digoxin & diuretics

56
Q

treatment of hypoplastic left heart syndrome

A

multiple surgeries that usually do not go well
-> most end up on the transplant list
