NURS 231 PATHOPHYSIOLOGY EXAM SCRIPT
TESTED QUESTIONS AND SOLUTIONS 100
PERCENT CORRECT
◉ A runner has depleted all the oxygen available for muscle energy.
Which of the following will facilitate his continued muscle
performance? Answer: Anaerobic glycolysis
◉ What causes the rapid change in the resting membrane potential
that initiates an action potential? Answer: Sodium gates open, and
sodium rushes into the cell, changing the membrane potential from
negative to positive.
◉ A 12-year-old male is diagnosed with Klinefelter syndrome. His
karyotype would reveal which of the following? Answer: XXY
◉ A nurse is reviewing the pedigree chart. When checking for a
proband, what is the nurse looking for? Answer: The person who is
first diagnosed with a genetic disease
◉ An aide asks the nurse why people who have neurofibromatosis
will show varying degrees of the disease. Which genetic principle
should the nurse explain to the aide? Answer: Expressivity
, ◉ In teaching a patient with cirrhosis, which information should the
nurse include regarding cholesterol? Answer: Cholesterol decreases
the membrane fluidity of the erythrocyte, which reduces its ability to
carry oxygen.
◉ A 15-year-old female is diagnosed with Prader-Willi syndrome.
This condition is an example of: Answer: Gene imprinting
◉ When a patient asks what causes cystic fibrosis, how should the
nurse respond? Cystic fibrosis is caused by an _____ gene Answer:
Autosomal recessive
◉ How are potassium and sodium transported across plasma
membranes? Answer: By adenosine triphosphate enzyme (ATPase)
◉ The nurse would be correct in identifying the predominant
extracellular cation as: Answer: Sodium
◉ The early dilation (swelling) of the cell's endoplasmic reticulum
results in: Answer: Reduced protein synthesis
◉ What principle should the nurse remember when trying to
distinguish aging from diseases? Answer: It is difficult to tell the
difference because both processes are believed to result from cell
injury.
