During cell injury caused by hypoxia, sodium and water move into the cell
because:
A) during cell injury cause by hypoxia, sodium and water move into the cell
because:
B) the pump that transports sodium out of the cell cannot function because
of a decrease in adenosine triphosphate (ATP) levels
C) the osmotic pressure is increased, which pulls additional sodium across
the cell membrane
D) oxygen is not available to bind with sodium to maintain it outside of the
cell - ANSWERS-Ans: C- the osmotic pressure is increased, which pulls
additional sodium across the cell membrane
What is an effect of ionizing radiation exposure?
A) respiratory distress
,B) sun intolerance
C) deoxyribonucleic acid (DNA) abberations
D) death - ANSWERS-Ans: C- deoxyribonucleic acid (DNA) abberations
Obesity creates a greater risk for dehydration in people because:
A) adipose cells contain little water because fat is water repelling
B) the metabolic rates of obese adults are slower than those of lean adults
C) the rates of urine output of obese adults are higher than thos of lean
adults
D) the thirst receptors of the hypothalamus do not function effectively -
ANSWERS-Ans: A- adipose cells contain little water because fat is water
repelling
In addition to osmosis, what force is involved in the movement of water
between the plasma and interstitial fluid spaces?
A) oncotic pressure
B) buffering
C) net filtration
D) hydrostatic pressure - ANSWERS-Ans: D- hydrostatic pressure
Venous obstruction is a cause of edema because of an increase in which
pressure?
A) capillary hydrostatic
B) interstitial hydrostatic
, C) capillary oncotic
D) interstitial oncotic - ANSWERS-Ans: A- capillary hydrostatic
At the arterial end of capillaries, fluid moves from the intravascular space
into the interstitial space because:
A) the interstitial hydrostatic pressure is higher than the capillary
hydrostatic pressure
B) the capillary hydrostatic pressure is higher than then capillary oncotic
pressure
C) the interstitial oncotic pressure is higher than the interstitial hydrostatic
pressure
D) the capillary oncotic pressure is lower than the interstitial hydrostatic
pressure - ANSWERS-Ans: B- the capillary hydrostatic pressure is higher
than then capillary oncotic pressure
Which component of the cell produces hydrogen peroxide (H2O2) by using
oxygen to remove hydrogen atoms from specific substrates in an oxidative
reaction?
A) lysosomes
B) peroxisomes
C) ribosomes
D) oxyhydrosomes - ANSWERS-Ans: B- peroxisomes
What is a consequence of plasma membrane damage to the mitochondria?
