UNE PATHOPHYSIOLOGY FINAL EXAM ACTUAL
TEST QUESTIONS AND CORRECT ANSWERS
◉ Which statement is a description of one of the characteristics of
apoptosis?
A) apoptosis involves programmed cell death of scattered singel
cells
B) apoptosis is characterized by the swelling of the nucleus and the
cytoplasm
C) apoptosis involves unpredictable patterns of cell death
D) apoptosis results in benign malignancies.
Answer: Ans: A- apoptosis involves programmed cell death of
scattered singel cells
◉ 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.
Answer: Ans: C- the osmotic pressure is increased, which pulls
additional sodium across the cell membrane
◉ Is the site of protein synthesis in a cell.
Answer: Which of the following is function of the rough endoplasmic
reticulum?
a. Contains hydrolytic enzymes
b. Is the site of protein synthesis in a cell
c. Packages protein for secretion to the outside of the cell
d. Produces ATP for cell function
◉ 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.
,Answer: Ans: A- adipose cells contain little water because fat is
water repelling
◉ Epigenetic modifications.
Answer: What genetic process is likely responsible for the
occurrence of asthma in only one of a pair of identical twins?
a. genomic imprinting
b. epigenetic modifications
c. methylation
d. transgenerational inheritance
◉ RNA is synthesized from a DNA template.
Answer: Transcription is best defined as a process by which
a. A base pair substitution results in a mutation of the amino acid
sequence
b. DNA polymerase binds to the promoter site on RNA.
c. RNA directs the synthesis of ribosomes for protein synthesis
d. RNA is synthesized from a DNA template
◉ nondisjunction error.
Answer: What is the most common cause of Down syndrome?
a. paternal translocation
, b. paternal viral illness
c. nondisjunction error
d. maternal viral illness
◉ klinefelter.
Answer: A person with XXXY has the genetic disorder called
__________ syndrome.
a. down
b. fragile x
c. klinefelter
d. turner
◉ autosomal recessive.
Answer: Cystic fibrosis is caused by an __________________ gene.
a. x-linked dominant
b. autosomal recessive
c. autosomal dominant
d. x-linked recessive
◉ What causes the clinical manifestations of confusion, convulsions,
cerebral hemorrhage, and coma in hypernatremia?
