Question 13 options: a) Plasma contains sodium and chloride, which influence the volume of solution. b) Volume affects perfusion more than the weight of solutes. c) More of the weight of plasma is influenced by solutes, such as proteins and glucose, rather than by water. d) Osmotic activity depends on the concentration of solutes present in plasma, such as proteins and glucose. Save Question 14 (0.5 points) Why is it possible for potassium to diffuse easily into and out of cells? Question 14 options: a) Potassium has a greater concentration in the ICF. b) Sodium has a greater concentration in the ECF. c) The resting plasma membrane is more permeable to potassium. d) An excess of anions is inside the cell Save Question 15 (0.5 points) What causes a rapid change in the resting membrane potential to initiate an action potential? Question 15 options: a) Potassium gates open, and potassium rushes into the cell, changing the membrane potential from negative to positive. b) Sodium gates open, and sodium rushes into the cell, changing the membrane potential from negative to positive. c) Sodium gates close, allowing potassium into the cell, changing the membrane potential from positive to negative. d) Potassium gates close, allowing sodium into the cell, changing the membrane potential from positive to negative. Save Question 16 (0.5 points) The action of the platelet-derived growth factor is to stimulate the production of which cells? Question 16 options: a) Platelets b) Epidermal cells c) Connective tissue cells d) Fibroblast cells Save Question 17 (0.5 points) What is a consequence of leakage of lysosomal enzymes during chemical injury? Question 17 options: a) Enzymatic digestion of the nucleus and nucleolus occurs, halting DNA synthesis. b) Influx of potassium ions into the mitochondria occurs, halting ATP production. c) Edema of the Golgi body occurs, preventing the transport of proteins out of the cell. d) Shifting of calcium out of the plasma membrane occurs, destroying the cytoskeleton. Save Question 18 (0.5 points) During cell injury caused by hypoxia, an increase in the osmotic pressure occurs within the cell because: Question 18 options: a) Plasma proteins enter the cell. b) The adenosine triphosphatase (ATPase-driven pump is stronger during hypoxia. c) Sodium chloride enters the cell. d) An influx of glucose occurs through the injured cell membrane. Save Question 19 (0.5 points) Which statement is true regarding the difference between a subdural hematoma and an epidural hematoma? Question 19 options: a) No difference exists, and these terms may be correctly used interchangeably. b) A subdural hematoma occurs above the dura, whereas an epidural hematoma occurs under the dura. c) A subdural hematoma is often the result of shaken baby syndrome, whereas an epidural hematoma rapidly forms as a result of a skull fracture. d) A subdural hematoma usually forms from bleeding within the skull, such as an aneurysm eruption, whereas an epidural hematoma occurs from trauma outside the skull, such as a blunt force trauma. Save Question 20 (0.5 points) During cell injury caused by hypoxia, sodium and water move into the cell because: Question 20 options: a) Potassium moves out of the cell, and potassium and sodium are inversely related. b) The pump that transports sodium out of the cell cannot function because of a decrease in 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 the cell.
