◉ Which of the following statements regarding alpha adrenergic
receptors is CORRECT?
Both alpha 1 and alpha 2 receptors cause vasoconstriction and
miosis.
Both alpha 1 and alpha 2 receptors cause vasoconstriction and
mydriasis.
Alpha 1 receptors cause vasoconstriction and mydriasis, and alpha 2
receptors cause vasoconstriction and miosis.
Alpha 1 receptors cause vasoconstriction and miosis, and alpha 2
receptors cause vasodilation and mydriasis.. Answer: Alpha 1
receptors cause vasoconstriction and mydriasis, and alpha 2
receptors cause vasoconstriction and miosis.
◉ Diarrhea and diabetes are MOST likely to result in which of the
following changes in blood plasma?
Increase in H+ and a decrease in pH
Increase in H+ and an increase in pH
,Decrease in H+ and a decrease in pH
Decrease in H+ and an increase in pH. Answer: Increase in H+ and a
decrease in pH
◉ Which of the following valves close to produce the first heart
sound during systole?
Mitral valve only
Mitral and tricuspid valves
Tricuspid valve only
Aortic valve only
Aortic and pulmonary valves
Pulmonary valve only. Answer: Mitral and tricuspid valves
"Try My Apple Pie"
◉ Diastole is represented by which of the following intervals on an
EKG?
P-QRS
P-T
QRS-T
T-ORS
,T-P. Answer: T-QRS
Remember systole is Q-T
◉ Which of the following changes would result in the GREATEST
INCREASE in resistance within an artery?
Decrease the length of the vessel
Increase the length of the vessel
Decrease the radius
Decrease the blood viscosity. Answer: Decrease the radius
◉ Which of the following changes in pressure will promote the
movement of water from capillaries into peripheral tissues?
Increase in capillary oncotic and hydrostatic pressures
Increase in capillary oncotic pressure and a decrease in capillary
hydrostatic pressure
Decrease in capillary oncotic and hydrostatic pressures
Decrease in capillary oncotic pressure and an increase in capillary
hydrostatic pressure. Answer: Decrease in capillary oncotic pressure
and an increase in capillary hydrostatic pressure
, Remember oncotic sucks, hydrostatic heart
◉ Which of the following changes results in an INCREASE in the
ejection fraction?
Increase in blood volume in a ventricle before contraction
Increase in blood volume in a ventricle after contraction
Decrease in stroke volume
Increase in heart rate. Answer: Increase in blood volume in a
ventricle before contraction - End Diastolic Volume
◉ When blood volume is low, angiotensin Il causes which of the
following 2 effects? SELECT 2
Stimulates the release of ADH from the posterior pituitary to
increase water absorption in the collecting duct of the nephron.
Stimulates the release of ADH from the hypothalamus to increase
Na+ reabsorption in the distal convoluted tubule of the nephron.
Stimulates the release of aldosterone from the adrenal cortex to
increase water reabsorption in the proximal convoluted tubule.
Stimulates the release of aldosterone from the adrenal cortex to
increase Na+ reabsorption in the distal convoluted tubule and
collecting duct of the nephron.. Answer: Stimulates the release of
