NURS 487 Week 1 Questions With Complete Solutions
4 things influencing CO within one person (not demographic
differences) Correct Answer Heart rate, preload, afterload,
contractility
Acute myocardial infarction Correct Answer Complete
interruption of blood supply to cardiac muscle. Sustained
ischemia leading to myocardial cell death
Angina Correct Answer Diminished blood flow and lack of
oxygen in the arteries in the heart (may lead to myocardial
ischemia. Chest pain that may or may not go away with rest.
Atherosclerosis Correct Answer Hardening of the arteries
with a build up of plaque that may impede blood flow or rupture
Atrial fibrillation Correct Answer Atria of the heart quiver
and loss of atrial kick (20-30% of SV)
Complicated hypertension Correct Answer Chronic
hypertension that damages the walls of the systemic blood
vessels and leads to organ damage
Dysrhythmia Correct Answer Problem with conduction
system of the heart
Electrolytes to monitor in patients with dysrhythmias Correct
Answer Sodium, potassium, magnesium, phosphorus, calcium
, Factors that influence BP (within body, not environmental)
Correct Answer Cardiac output, systemic vascular resistance,
blood volume, blood viscosity, elasticity of vessel walls
How are murmurs assessed (3) Correct Answer Loudness (six
grades), timing (diastole or systole), pitch (low, medium, high)
HR - normal, tachycardia, bradycardia Correct Answer
Normal - 60-100bpm
Tachycardic - >100 bpm
Bradycardic - <60 bpm
Hypertensive crisis Correct Answer Severe and abrupt
elevation in BP with a diastolic >120 mmHg. Monitor for neuro
dysfunction and organ failure
Hypotension Correct Answer Low blood pressure < 95/60.
Inadequate tissue perfusion due to a compromised cardiac output
Isolated hypertension Correct Answer Sustained systolic
blood pressure >130 accompanied by normal diastolic blood
pressure < 90mmHg
Labs to monitor for a patient with acute myocardial infarction
Correct Answer Lipids and troponin
Left ventricle dysfunction sign in acute myocardial infarction
Correct Answer Course crackles in lungs (fluid). Will be heard
first in lower lungs (auscultated on pt back)
