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. Question 2 2 / 2 pts 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
