The nurse is calculating a client's cardiac output. For this calculation, the nurse needs to know the client's stroke volume. Stroke volume is the:
a. volume of blood pumped by the heart in 1 minute.
b. measurement of pressure pulsations exerted against the blood vessel walls during systole and diastole.
c. bounding of blood flow in an artery.
d. measurement of blood that enters the aorta with each ventricular contraction.
Question 2
The nurse is listening to a client's heart sounds. Which statement is true about systole?
a. At the onset of systole, the pressure in the ventricles is less than that in the atria.
b. During this phase, the mitral and tricuspid valves close, producing the first heart sound.
c. Blood flows from the atria into the ventricles.
d. The atria contract, sending blood into the ventricles.
An analogy for how cardiac output, resistance, and blood pressure are related.
The three types of muscles: skeletal, smooth, and cardiac.
