NURSING NSG5003 Week 6 Mid-term
These are all from the test bank for the textbook.

What causes the rapid change in the resting membrane potential to initiate an action potential?

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 to change the membrane potential from
positive to negative.

d. Potassium gates close, allowing sodium into the cell to change the membrane potential from
positive to negative.



What is a consequence of leakage of lysosomal enzymes during chemical injury?

a. Enzymatic digestion of the nucleus and nucleolus occurs, halting DNA synthesis.

b. Influx of potassium ions into the mitochondria occurs, halting the ATP production.

c. Edema of the Golgi body occurs, preventing the transport of proteins out of the cell.

d. Shift of calcium out of the plasma membrane occurs, destroying the cytoskeleton.



In hypoxic injury, sodium enters the cell and causes swelling because:

a. The cell membrane permeability increases for sodium during periods of hypoxia.

b. ATP is insufficient to maintain the pump that keeps sodium out of the cell.

c. The lactic acid produced by the hypoxia binds with sodium in the cell.

d. Sodium cannot be transported to the cell membrane during hypoxia.



What mechanisms occur in the liver cells as a result of lipid accumulation?

a. Accumulation of lipids that obstruct the common bile duct, preventing flow of

bile from the liver to the gallbladder

b. Increased synthesis of triglycerides from fatty acids and decreased synthesis of apoproteins

c. Increased binding of lipids with apoproteins to form lipoproteins

d. Increased conversion of fatty acids to phospholipids

, During an IgE-mediated hypersensitivity reaction, the degranulation of mast cells is a result of which
receptor action?

a. Histamine bound to H2

b. Chemotactic factor binding to the receptor

c. Epinephrine bound to mast cells

d. Acetylcholine bound to mast cells



What is the mechanism that results in type II hypersensitivity reactions?

a. Antibodies coat mast cells by binding to receptors that signal its degranulation, followed by
a discharge of preformed mediators.

b. Antibodies bind to soluble antigens that were released into body fluids, and the immune
complexes are then deposited in the tissues.

c. Cytotoxic T lymphocytes or lymphokine-producing helper T 1 cells directly attack and destroy
cellular targets.

d. Antibodies bind to the antigens on the cell surface



Type III hypersensitivity reactions are a result of which of the following?

a. Antibodies coating mast cells by binding to receptors that signal its degranulation, followed by
the discharge of preformed mediators

b. Antibodies binding to soluble antigens that were released into body fluids and the immune
complexes being deposited in the tissues

c. Tc cells or lymphokine-producing Th1 cells directly attacking and destroying cellular targets

d. Antibodies binding to the antigen on the cell surface.



Tissue damage caused by the deposition of circulating immune complexes containing an antibody
against the host DNA is the cause of which disease?

a. Hemolytic anemia

b. Pernicious anemia

c. Systemic lupus erythematosus

d. Myasthenia gravis
