NURS231 FINAL EXAM WITH CORRECT ANSWERS
A bodybuilder's muscles will display hyperplasia.
False
Barrett esophagus
Is an example of dysplasia?
False
Hypertrophy is an increase in the size of an organ or tissue caused by an increase in the number of cells
True
Lack of nerve stimulation can cause cells to atrophy
True
Proportion of people with a disease who are positive for the disease
Sensitivity
How likely the same result will occur if repeated
Reliability
,How a tool measures what it is intended to measure
Validity
People without the disease who are negative on a given test
Specificity
Which is NOT true of the cytoskeleton?
It includes peroxisomes and proteasomes
Which of the following are true of the cell? Select all that apply.
1: Proteins carry out the functions of the cell membrane
2: Lysosomes are the digestive system of the cell
3: Microfilaments are thin, threadlike cytoplasmic structures
Which are true of the cell membrane? Select all that apply.
1: Controls the transport of materials from the outside fluids to within
2: Helps with the conduction of electrical currents in nerve and muscle cells
3: Aids in the regulation of cell growth and proliferation
Which are false of the mitochondria? Select all that apply.
1: They are found far from the site of energy consumption.
2: They control free radicals.
,High blood pressure is an example of which of the following?
Pathophysiology
A patient complains of chest pain and an elevated blood pressure. What are these examples of?
Signs and symptoms
Which of the following is true of a test's sensitivity?
If negative, it can safely be assumed that the person does not have a disease
Chemical agents (poison, alcohol) are examples of which of the following?
Etiologic factors
Define tertiary prevention and give an example:
Tertiary prevention occurs after a disease has been diagnosed and clinical intervention is needed to reduce
complications or deterioration. One example is the use of certain medications one must take after a heart
attack to help reduce the risk of a future event or death.
Compare and contrast the two types of gangrenous necrosis.
In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes to dark
brown or black. The spread of dry gangrene is slow. It results from a cut off in arterial blood supply and is a
form of coagulation necrosis. In wet gangrene, the affected area is cold, swollen, and pulseless. The skin is
, moist, black, and under tension. Blebs form on the surface, liquefaction occurs, and a foul odor is caused by
bacterial action. The spread of tissue damage is rapid.
Explain what necrosis is and give an example and description of one type of necrosis.
Necrosis is cell death to an organ or tissue with still being a part of a living person. An example of this would
be liquefactive necrosis. This is when the cells die and the catalytic enzymes do not get destroyed after the
cells death. This could cause necrosis
Sunburn
Radiation injury
Obesity
Nutritional imbalances
Reactive oxygen species
Free radical injury
Low oxygen to tissues
Hypoxic cell injury
Fractures
