Anurse needs to calculate a client's cardiac output. the client's heart rate is 80 beats per minute. which other measurements does the nurse need to calculate the cardiac output? afterload, blood pressure, and preload preload, afterload, and contractility afterload, preload, and ejection fraction contractility, preload, and compliance blood pressure, ejection fraction, compliance

Answer;

Preload, afterload, and contractility

Explanation;Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload.Preload is the initial stretching of the cardiac myocytes or muscle cells prior to contraction. Afterload is the force or load against which the heart has to contract to eject the blood.Contractility is the intrinsic strength of the cardiac muscle independent of preload, but a change in preload will affect the force of contraction.
