What does HR stand for in medical terms?
Heart Rate
High Risk
Health Ratio
Heart Rhythm
What is the normal range for heart rate in beats per minute (bpm)?
60-100 bpm
50-90 bpm
70-110 bpm
80-120 bpm
What is the normal range for stroke volume (SV) in milliliters?
50-80 ml
70-100 ml
90-120 ml
100-130 ml
What does EDV stand for in the context of stroke volume?
End Diastolic Volume
End Systolic Volume
Extra Diastolic Volume
Extra Systolic Volume
What does ESV represent in the calculation of stroke volume?
End Systolic Volume
End Diastolic Volume
Extra Systolic Volume
Extra Diastolic Volume
What is the state of the ventricles during systole?
They are full
They are mostly empty
They are relaxed
They are filling
What is the formula for calculating Stroke Volume (SV)?
SV = EDV - ESV
SV = ESV - EDV
SV = EDV + ESV
SV = EDV / ESV
If the End Diastolic Volume (EDV) is 144 ml and the End Systolic Volume (ESV) is 50 ml, what is the Stroke Volume (SV)?
94 ml
194 ml
50 ml
144 ml
What does SV represent in the context of the heart?
How much was ejected with each squeeze
The total blood volume in the body
The heart rate per minute
The pressure in the arteries
What does "CO" stand for in the context of the cardiovascular system?
Cardiac Output
Cardiac Overload
Cardiac Operation
Cardiac Obstruction
What is the normal range for cardiac output (CO) in liters per minute?
2-5 L/min
4-8 L/min
6-10 L/min
8-12 L/min
How is cardiac output (CO) calculated?
CO = HR + SV
CO = HR - SV
CO = HR x SV
CO = HR / SV
What is the formula for calculating cardiac output (CO)?
CO = HR x SV
CO = HR + SV
CO = HR / SV
CO = HR - SV
If the heart rate (HR) is 75 beats per minute and the stroke volume (SV) is 94 mL, what is the cardiac output in liters per minute?
7.05 L/min
6.50 L/min
8.00 L/min
5.75 L/min
What happens to cardiac output when the body's demand for oxygenated blood increases?
It decreases
It remains the same
It increases
It stops
How might the body increase cardiac output?
Decrease heart rate
Increase heart rate and/or stroke volume
Decrease stroke volume
Stop blood flow
What does BSA stand for in medical terms?
Body Surface Area
Body Size Analysis
Biological Surface Area
Basic Size Assessment
Which formula is used to calculate Body Surface Area (BSA)?
Mosteller formula
BMI formula
Harris-Benedict formula
Broca's formula
What is the average BSA for adults?
1.73 m²
2.0 m²
1.5 m²
1.9 m²
What is the important concept to understand about measurements in relation to patient size?
All measurements are the same regardless of patient size.
Measurements are graded based on how big the patient is.
Measurements are irrelevant to patient size.
Measurements are only important for small patients.
What does the Cardiac Index (CI) represent?
The total blood volume in the body
Cardiac output corrected for body surface area (BSA)
The heart rate per minute
The blood pressure in arteries
What is the formula for calculating the Cardiac Index (CI)?
CI = BSA / CO
CI = CO x BSA
CI = CO / BSA
CI = BSA / heart rate
What is the normal range for Cardiac Index (CI)?
1-2 L/min/m²
3-4 L/min/m²
5-6 L/min/m²
7-8 L/min/m²
What is the abbreviation for Blood Pressure?
HR
BP
SV
CO
Which formula is used to calculate Stroke Volume (SV)?
SV / HR
EDV-ESV
CO / BSA
Beats / 1 min
What is the formula for Body Surface Area (BSA)?
SV / HR
CO / BSA
√(Height (cm) x Weight (Kg) / 3600)
EDV-ESV
