Thromboangiitis obliterans (Buergers c. Strongly associated with smoking
disease) is an autoimmune condition
that is:
a. A result of over activation of the
intrinsic and extrinsic clotting system
systemically
b. Characterized by attacks of
vasospasm in the small arteries and
arterioles of the fingers and toes
c. Strongly associated with smoking
d. Associated with janeway lesions
and Oslers Nodes
,Which of the following is not a a. Congestive Heart Failure
systemic disease that is associated
with Raynaud's Phenomenon?
a. Congestive heart failure
b. Collagen vascular diseases such as
scleroderma
c. Pulmonary hypertension
d. Myxedema or smoking
Which of the following is NOT a c. Total peripheral (systemic) resistance
primary factor in determining
preload?
a. Venous return during diastole
b. End systolic volume
c. Total peripheral (systemic)
resistance
d. All of the above are primary
factors of preload
,Which of the following statements d. Prostacyclins, which are diminished by NSAIDS,
are INCORRECT are vasoconstrictors
a. The mean arterial pressure is the
average force of pushing blood
through the systemic circuit.
b. The pulse pressure is the
difference between systolic and
diastolic pressures
c. A decrease in aortic compliance
increases its stiffness and thus can
lead to an increase in pulse
pressures
d. Prostacyclins, which are
diminished by NSAIDs, are
vasoconstrictors.
Which of the following is incorrect b. The atria are contracting
regarding the isometric contraction
phase of the cardiac cycle?
a. Blood does not flow through the
heart at this time.
b. The atria are contracting
c. The valves are closed
d. It occurs during ventricular systole
, The resistance of movement of d. Afterload
blood from the left ventricle to the
aorta is termed the:
a. Ejection fraction
b. Compliance
c. Preload
d. Afterload
Natriuretic peptides act by: b. Stimulate the release of Na+ (thus increasing
urine volume) from the kidneys
a. Stimulates secretion of Na+ (and
thus decreases urine volume) from
the kidneys
b. Stimulated the release of Na+ (thus
increases urine volume) from the
kidneys
c. Increases vascular smooth muscle
contraction (vasoconstriction)
d. Stimulates increased heart rate,
contractility, and cardiac output
