The pulse pressure is a measure of a. the number of heartbeats per minute. b. the sum of the diastolic and systolic pressures. c. the difference between the systolic and diastolic pressures. d. the difference between the arterial and venous pressures.

Which statement about atrial contraction is true.   A the end diastolic volume is the volume of blood that enters the ventricles during atrial contraction   B the end diastolic volume is the volume of blood in the atria at the end of diastole   C most of the filling of the ventricles occurs during atrial contraction   D when atrial contraction begins the ventricles are already about 80% full

Atrial flutter is characterized by A.  An atrial rate slower than the ventricular rate B.  Waves with a saw tooth or picket fence pattern C.  An atrial rate between 160 and 220 beats per minute D.  All of the above

A patient hospitalised with aortic stenosis has activity intolerance related to insufficient oxygen due to decreased cardiac output. An appropriate nursing intervention for this patient is to: Select one: a. Progressively increase activity to increase cardiac tolerance b. Maintain on bed rest to reduce tissue oxygen demands c. Monitor electrocardiography to assess cardiac output d. Use a Semi-Fowler position to decrease venous return and increase respiratory excursion

Primary force driving fluid out of the capillary and into interstitial fluid is: a. Interstitial fluid colloid osmotic pressure (ICOP). b. Interstitial fluid hydrostatic pressure (IHP). c. None of the above. d. Blood colloid osmotic pressure(BCOP). e. Capillary Hydrostatic pressure (CHP).

Afterload is Select one: a. the amount cardiac output must increase during exercise. b. the arterial pressure that the ventricles must overcome to eject blood. c. the extent to which ventricular walls are stretched. d. the name given to an increase in end-diastolic volume. e. another name for venous return.
