Cardio Flashcards
Unoxygenated blood comes from
Heart to lungs
Oxygenated blood comes from
Lungs to heart
Cardiac output
Amount of blood pumped by each ventricle in 1 min
Heart rate is controlled by
Autonomic nervous system
Stroke volume is affected by
Amount of blood pushed with each contraction
- preload
- contractility
After,old
Preload
What is left in the chamber at the end of a contraction
After load
What is the pressure / force the heart needs to contract
What happens when heart failure occurs?
Kidneys compensate
- producing aldosterone
Pulse pressure
Difference between systolic and dystolic pressure
- 40-60
Mean arterial pressure
Average pressure with arterial system that is felt by an organ
Map= systolic pressure + (2) dystolic pressure /3
Goal for cardiovascular system
Recognize early cues and interview before patient declines
What is considered an orthostatic blood pressure
Systolic dropping more then 20
Where do you listen for heart sounds
Think : ape to man
Aortic
Pulmonic
Erbs point
Tricuspid
Mitral
During auscultation, what are you listening for
S1 & s2
Lub dub
- anything different = s3/ s4
What do you record if you hear an abnormal sound when auscultating
Timing
Location
Position of patient
Sign of hypervolemia
Jugular venous distinction
Common diagnostic tests for cardiac issues
Troponin
Cck
Bnp - brain type naturietic peptide
Lipids
Echocardiogram
Ultrasound that shows wave movements of heart
- helps determine abnormalities
The P Qrs T waves are showing
Electrical impulses
Common causes of dysrhythias
Electrolyte imbalances
Dehydration
Coffe
Tobacco
Exercise
Sleep issues
A fib is usually more likely for a person to experience a _____
Stroke
A patient is receiving a drug that decreases after load, what should the nurse monitor
Heart rate
Lung sounds
Blood pressure
Jugular vein dissent ion
Blood pressure
A patient returns to the cardiac observation area following a cardiac Catherine Timon with coronary angiography. Which assessment would require immediate action?
Apical of 54 beats/ min
St segment elevated on ecg
Pedal pulse is 2+ bilaterally
Mean arterial pressure 72
St segment elevated
Mean arterial pressure needs to be greater then ___ to perfume vital organs
60
