In systolic heart failure, what effect does the renin-angiotensin-aldosterone
system (RAAS) have on stroke volume? Select one.
Question options:
a) Decreases preload and decreases afterload
b) Decreases preload and increases afterload
c) Increases preload and decreases afterload
d) Increases preload and increases afterload
Hide question 1 feedback
Feedback
Activation of the RAAS increases preload through the effects of aldosterone secretion, a
activity. RAAS also increases afterload through vasoconstriction mediated by angiotensi

What is an expected change in the cardiovascular system that occurs with
aging? Select one.
Question options:
a) Arteriosclerosis
b) Decreased left ventricular wall tension
c) Arterial stiffening
d) Decreased aortic wall thickness
Hide question 2 feedback
Feedback
Arterial stiffening occurs with aging even in the absence of clinical hypertension. Aging

, A healthcare provider is assessing a patient who has a pericardial effusion
and notes a pulsus paradoxus. A student asks for an explanation of how this
occurs. What description by the professional is best? Select one.
Question options:
a) Blood ejected from the left atrium and reduction of blood volume in the left ventric
b) Blood ejected from the right atrium and reduction of blood volume in the right ven
c) Diastolic filling pressures of the right ventricle and reduction of blood volume in bo
d) Diastolic filling pressures of the left ventricle and reduction of blood volume in all
Hide question 3 feedback
Feedback
Pulsus paradoxus means that the arterial blood pressure during expiration exceeds arte
inspiration by more than 10 mmHg. This clinical finding reflects impairment of diastolic
ventricle plus a reduction of blood volume within all four cardiac chambers.
