NSG 5003 Midterm
Question 1

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

Question 1 options:
Potassium gates open and potassium rushes into the cell, changing the membrane potential from negativ
to positive


Sodium gates open and sodium rushes into the cell, changing the membrane potential from negative to
positive.


Sodium gates close, allowing potassium into the cell to change the membrane potential from positive to
negative.


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


Question 2

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

Question 2 options:
Enzymatic digestion of the nucleus and nucleolus occurs, halting deoxyribonucleic acid (DNA) synthes


Influx of potassium ions into the mitochondria occurs, halting the adenosine triphosphate (ATP)
production.


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


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


Question 3

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

Question 3 options:
The cell membrane permeability increases for sodium during periods of hypoxia.

, Adenosine triphosphate (ATP) is insufficient to maintain the pump that keeps sodium out of the cell.


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


Sodium cannot be transported to the cell membrane during hypoxia.


Question 4

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

Question 4 options:
Obstruction of the common bile duct, preventing the flow of bile from the liver to the gallbladder


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


Increased binding of lipids with apoproteins to form lipoproteins


Increased conversion of fatty acids to phospholipids


Question 5

Which solution is best to use when cleaning a wound that is healing by 101. During an
Immunoglobulin E (IgE)-mediated hypersensitivity reaction, the degranulation of mast cells is
a result of which receptor action?

Question 5 options:
Histamine bound to H2


Chemotactic factor binding to the receptor


Epinephrine bound to mast cells


Acetylcholine bound to mast cells


Question 6

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

,Question 6 options:
Antibodies coat mast cells by binding to receptors that signal its degranulation, followed by a discharge
of preformed mediators.


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


Cytotoxic T (Tc) lymphocytes or lymphokine-producing helper T 1 (Th1) cells directly attack and destr
cellular targets.


Antibodies bind to the antigens on the cell surface.


Question 7

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

Question 7 options:
Antibodies coating mast cells by binding to receptors that signal its degranulation, followed by the
discharge of preformed mediators


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


Cytotoxic T (Tc) cells or lymphokine-producing helper T 1 (Th1) cells directly attacking and destroying
cellular targets


Antibodies binding to the antigen on the cell surface


Question 8

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

Question 8 options:
Hemolytic anemia


Pernicious anemia

, Systemic lupus erythematosus


Myasthenia gravis


Question 9

Why does tissue damage occur in acute rejection after organ transplantation?

Question 9 options:
Th1 cells release cytokines that activate infiltrating macrophages, and cytotoxic T (Tc) cells directly
attack the endothelial cells of the transplanted tissue.


Circulating immune complexes are deposited in the endothelial cells of transplanted tissue, where the
complement cascade lyses tissue.


Receptors on natural killer (NK) cells recognize antigens on the cell surface of the transplanted tissue,
which releases lysosomal enzymes that destroy tissue.


Antibodies coat the surface of the transplanted tissue to which mast cells bind and liberate preformed
chemical mediators that destroy tissue.


Question 10

Oncogenes are genes that are capable of:

Question 10 options:
Undergoing mutation that directs the synthesis of proteins to accelerate the rate of tissue proliferation


Directing synthesis of proteins to regulate growth and to provide necessary replacement of tissue


Encoding proteins that negatively regulate the synthesis of proteins to slow or halt the replacement of
tissue


Undergoing mutation that directs malignant tissue toward blood vessels and lymph nodes for metastasis
