Question 1
2 / 2 pts
Which are indications of dehydration?
Correct!
Tachycardia and weight loss
Decreased hemoglobin and hematocrit
Muscle weakness and decreased deep tendon reflexes
Polyuria and hyperventilation
Marked water deficit is manifested by symptoms of dehydration: headache, thirst, dry skin and mucous membranes, elevated temperature, weight loss, and decreased or concentrated urine (with the exception of diabetes insipidus). Skin turgor may be normal or decreased. Symptoms of hypovolemia, including tachycardia, weak pulses, and postural hypotension, may be present.

At the arterial end of capillaries, fluid moves from the intravascular space into the interstitial space because the
interstitial hydrostatic pressure is higher than the capillary hydrostatic pressure.
capillary oncotic pressure is lower than the interstitial hydrostatic pressure.
interstitial oncotic pressure is higher than the interstitial hydrostatic pressure.
Correct!
capillary hydrostatic pressure is higher than the capillary oncotic pressure.
At the arterial end of capillaries, fluid moves from the intravascular space into the interstitial, because capillary hydrostatic pressure is higher than the capillary oncotic pressure.
Question 3

Which enzyme is secreted by the juxtaglomerular cells of the kidney when circulating blood volume is reduced?
Angiotensin II
Aldosterone
Angiotensin I
Correct!
Renin
When circulating blood volume or blood pressure is reduced, renin, an enzyme secreted by the juxtaglomerular cells of the kidney, is released in response to sympathetic nerve stimulation and decreased perfusion of the renal vasculature.
