✓ Midterm 6501 Walden University
✓ 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.

✓ 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.
✓ What is the diagnosis of a 13-year-old female who has a karyotype that
reveals an absent homologous X chromosome with only a single X
chromosome present? Her features include a short stature, widely spaced
nipples, reduced carrying angle at the elbow, and sparse body hair.
Answer: Turner syndrome
