Cardiovascular Dysfunction Flashcards
How the does the ductus arteriosus close
from oxygen cause vasoconstriction
When is the functional closure of the ductus arteriosus suppose to happen
48-72 hours
About when will the anatomical closure of ductus arteriosus happen
10-21 days
What is an conplication of a ductus arteriosus that stays open too long and why
pulmonary edema resulting in tachypnea and lung crackles
bec too much blood is going to the lungs
Nursing care for pulmonary edema from patent ductus arteriosus
NSAID bec they stop prostaglandins
O2
fluid restriction - might order diuretics
What type of surgery would be used to fix a patent ductus arteriosus
ligation
What surgery would not be used to fix a patent ductus arteriosus
bypass
When would be not want to close a patent duct arterio
when other defects cause the baby to need the ductus arteriosus to live
What are some signs of supraventricular tach
racing heart
angina
dizziness
non-hospital nursing care for supraventricular tach
bare down act like your pooping
ice to face
carotid massage
What type of med treats supraventricular tach
adenosine
What does atropine do
increases HR by decreases AV node resistance
How is adenosine given
fast IV push
What treatment if adenosine doesnt work
cardioversion
What is a nursing con when a pat is scheduled for a cardioversion
advocate for pain meds
What are some symptoms of a CHF
edema
crackles
poor feeding - evidence of fatigue
portal HTN
treatment for CO for CHF pats
inotropics- digoxin
diuretics/fluid restrictions
Signs of dig toxicity
Confusion.
Nausea, vomiting, diarrhea.
yellow green rings in vision
What are some things that would indicate transposition of the great arteries
if a baby’s O2 sat wont go above the 80’s, is otherwise normal besides cyanosis, and the O2 sat gets worse when youu give O2 or NSAIDS
Why would giving O2 or NSIADS with Transposition of the great arteries make things worse
bec the ductus arteriosus is the only thing getting O2 to the rest of the body so O2 or NSAIDS would make it close
What meds would you give a trans position of great arts pat
prostaglandins
What might be some side effects of prostaglandin meds
fever
apnea
Nursing care for transpot of G art pat before travel to states
NPO
prostaglandins
IV fluids
meds for intubation
How is prostaglandins given
continuous IV
What are the signs of coarctation of aorta
bounding pulse in upper extremities and absent pulse in lower
cool and clammy
poor feeding
What is coarctation of aorta
narrowing of a short section of the aorta
What are some things to assess for when coarc of aorta is suspected
pulse differential between lower and upper extremities
BP on all four limbs - usu 10mm diff
What is a nursing con for someone with coarc of aorta
ductus arteriosus needs to stay open until surgery
What are the 4 defects associated with Tetrology of Fallot
pulmonic stenosis
VSD
right vent hypertrophy
overriding aorta
What are the s/s of kawasaki’s disease
high fever
red lips
strawberry tongue
Treatment for kawasaki
high dose IV immunoglobin G
Aspirin
What is kawasakis dis
inflammation in blood vessels
What defect is used to indicate the level of severity of tetrology of fallot
pulmonic stenosis - the more stenosis the worse
treatment for Tet of Fallot
prostaglandins to help perfusion
surgery
What is a Tet spell
rapid development of cyanosis
What triggers tet spells
things that increase O2 demand like
feeding
crying
Nursing care for Tet spells
put their knees up toward chest
for kid have them squat
What is some discharge teaching for tet of fallot
knee to chest
minimize pain
minimize illness bec causes dehy so advocate for vaccines
