bound to hemoglobin in red blood cells
attached to platelets
dissolved in the blood plasma
combined with carbon dioxide
How do you calculate the oxygen content in arterial blood?
CO2 is transported –
By RBC
As bicarbonates
In a dissolved state through plasma
All

What is stroke volume?
the volume of oxygen transported in the blood
the volume of blood pumped out of the heart each minute
the volume of blood pumped out of the heart in each beat
the number of beats per minute
The blood vessels which carry oxygenated blood
Vein
Artery
Both
None
The amount of force placed on the walls of your arteries as your heart pumps (contracts and then relaxes) is called
blood pressure.
blood volume.
blood viscosity.
heart rate (pulse).
High temperature decreases hemoglobin's affinity for oxygen
True
false
In which blood vessels connected to the heart does the blood have the lowest carbon dioxide concentration?
Pulmonary vein
Vena cava
Pulmonary artery
Coronary vein
Hemoglobin must have _____ for oxygen to bind properly
Calcium
Iron
Carbon Dioxide
A GED
What are the 3 pathophysiological mechanism of hypotension
Decreased Preload
Hypoventilation
Decreased cardiac function
Decreased systemic vascular resistance
A decrease in systemic vascular resistance can be treated with:
vasopressors
positive inotropes
ace-inhibitors
intravenous fluid
The amount of blood (mL) coming from one ventricle in one minute is called:
the preload
the afterload
the stroke volume
the cardiac output
afterload is
degree of stretch of heart muscle
pressure the ventricles must overcome to eject blood
pressure the atria must overcome to eject blood
the amount of blood remaining after contraction
preload is
pressure the aria must overcome to eject blood
pressure the ventricles must overcome to eject blood
the amount of blood before contraction
degree of stretch of heart muscle
A patient presents with shortness of breath, hematemesis, and diarrhea. They're tachypneic, hypotensive, and tachycardic. The arterial oxygen saturation (SaO2) is reading 88%, hemoglobin is 8 g/dL, and PaO2 is 58 mmHg. What is the patient's arterial oxygen content (CaO2)?
15.34 mL O2/dL of blood
9.61 mL O2/dL of blood
5.64 mL O2/dL of blood
20.23 mL O2/dL of blood
How does the body respond when more oxygen is required?
Decreasing heart rate
Increasing heart rate
Decreasing blood pressure
Increasing blood pressure
The function of valves in the human circulatory system is to
stimulate the heart beat.
accelerate the flow of blood.
prevent the backward flow of blood.
serve as a cushion to prevent friction
Which of the following conditions could result in an elevated CVP reading?
Dehydration
Hypovolemia
Cardiac arrest
Hypervolemia
