NR 464 EXAM PRACTICE QUESTIONS WITH
100% VERIFIED ANSWERS!!
what is shock?
syndrome characterized by decreased tissue perfusion and impaired cellular metabolism
imbalance in supply and demand of O2 and nutrients
what is cardiogenic shock?
low blood flow
systolic or diastolic dysfunction
compromised cardiac output
what are the precipitating causes of cardiogenic shock?
Myocardial infarction
Cardiomyopathy
Blunt cardiac injury
Severe systemic or pulmonary
hypertension
Cardiac tamponade
Myocardial depression from metabolic problems
what is the patho of cardiogenic shock?
,- decreased contractility
- dysrhythmias
- increased afterload
- increased preload
CRAP acronym
what is preload?
the amount of blood in the ventricles at the end of diastole
what are the early findings of cardiogenic shock?
tachycardia
hypotension
narrowed pulse pressure
increased myocardial O2 consumption
expression of feeling of doom
what physical assessments will you find with a patient in cardiogenic shock?
tachypnea, pulmonary congestion
pallor, cool, clammy skin
decreased cap refill time
abnormal heart sounds
, decreased renal profusion
n/v
hypoactive BS
what is the collaborative care for cardiogenic shock?
overall goal: restore blood flow to the myocardium by restoring the balance between O2 and
demand
angioplasty with stunting
emergency revascularization
valve replacement
hemodynamic monitoring
diagnostic studies
drug therapy
fluid and salt restrictions
circulatory assist devices
heart transplant
what drugs could we give to this patient for a positive inotropic effect? (IV only)
dopamine
-moderate dose**
