NURS 2245 Heart Failure | Questions with 100% Verified Answers | Latest
Update
Question: Why is heart failure considered a "syndrome" and not a
disease?
Answer:
multi causative (not usually one direct cause)
Question: Heart failure occurs when the heart becomes incapable of
maintaining enough _________ ___________ to meet the metabolic
demands of the body
Answer:
cardiac output
Question: Patients with this condition are at 2x risk for developing heart
failure
Answer:
systemic HTN (systolic EF less than 40%)
Question: Aside from HTN, what are some other risk factors for heart
failure?
Answer:
MI, DM, valvular disease, CKD, anemia, infection, drug use, obesity, hyperthyroidism
Question: (1/5) Patients with heart failure have increased levels of this
neurotransmitter/hormone in their cardiac tissue
Answer:
norepinephrine
Question: (2/5) Increased norepi leads to stimulation of the...
Answer:
sympathetic nervous system
Question: (3/5) SNS stimulation leads to increased __________ and
___________, as well as _____________
Answer:
HR, contractility, vasoconstriction
, Question: (4/5) End result of HF-induced norepi activation?
Answer:
elevated BP, decreased renal perfusion
Question: (5/5) How does all of the above affect the workload of the
heart?
Answer:
preload, CO, HR, BP all INCREASE
Question: Chronically increased preload can lead to these ventricular
changes
Answer:
remodeling (dilation, overstretching)
Question: What diagnostic test can be used to determine if HF is low
output of high output?
Answer:
2D echocardiogram (EF)
Question: TYPE OF HF: cardiac output is normal, but metabolic needs
are not met
Answer:
high output
Question: TYPE OF HF: the heart fails as a pump
Answer:
low output
Question: TYPE OF HF: ventricle unable to CONTRACT with enough
force to eject adequate volume
Answer:
systolic dysfunction (EF less than 40%, more common than diastolic)
Question: TYPE OF HF: left ventricle in unable to RELAX enough to
adequately refill chambers with blood
Answer:
diastolic dysfunction (EF more than 40%)
