MULTIPLE CHOICE 1. The characteristics of arterial pulses are directly affected by all of the following except: a. the volume of blood ejected. b. peripheral arterial resistance. c. venous valvular competence. d. blood viscosity. e. distensibility of aorta. ANS: C
Arterial pulses are affected by stroke volume (volume of blood ejected), distensibility of the aorta and large arteries, viscosity of the blood, and peripheral arteriolar resistance. Venous valvular competence contributes to the venous blood flow back to the heart. TOP: Discipline: Physiology
MSC: Organ System: Cardiovascular
2. The level at which the jugular venous pulse is visible gives an indication of: a. mitral valve efficiency. b. aortic valve efficiency. c. stroke volume. d. left ventricular pressure. e. right atrial pressure. ANS: E

The level at which the jugular venous pulse is visible indicates right atrial pressure. The jugular veins empty into the superior vena cava, which empties into the right atria. The jugular venous system reflects the competency of the right side of the heart. The other four possible answers reflect the competency of the left side of the heart. TOP: Discipline: Physiology
MSC: Organ System: Cardiovascular
3. Vascular changes expected in older adults include: a. loss of vessel elasticity. b. decreased peripheral resistance. c. decreased pulse pressure. d. constriction of the aorta and major bronchi. e. increased vasomotor tone. ANS: A
With age, the walls of the arteries become calcified, and they lose their elasticity and vasomotor tone; therefore, they lose their ability to respond appropriately to changing body needs. Increased peripheral vascular resistance occurs, causing an increase in blood pressure. TOP: Discipline: Physiology
MSC: Organ System: Cardiovascular
4. Which of the following statements is true regarding the examination of peripheral arteries? a. The thumb should never be used to assess pulses.
