Advanced Pathophysiology Midterm 6501 Walden
University question and answer by A+ solutions
1. A runner has depleted all the oxygen available for muscle energy. Which of
the following will facilitate his continued muscle performance? - Correct
Answer Answer: Anaerobic glycolysis
2. What causes the rapid change in the resting membrane potential that initiates
an action potential? - Correct Answer Answer: Sodium gates open, and
sodium rushes into the cell, changing the membrane potential from negative
to positive.
3. A 12-year-old male is diagnosed with Klinefelter syndrome. His karyotype
would reveal which of the following? - Correct Answer Answer: XXY
4. A nurse is reviewing the pedigree chart. When checking for a proband, what
is the nurse looking for? - Correct Answer Answer: The person who is first
diagnosed with a genetic disease
5. 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? - Correct Answer Answer: Expressivity
6. In teaching a patient with cirrhosis, which information should the nurse
include regarding cholesterol? - Correct Answer Answer: Cholesterol
decreases the membrane fluidity of the erythrocyte, which reduces its ability
to carry oxygen.
7. When a patient asks what causes cystic fibrosis, how should the nurse
respond? Cystic fibrosis is caused by an _____ gene - Correct Answer
Answer: Autosomal recessive
, 8. How are potassium and sodium transported across plasma membranes? -
Correct Answer Answer: By adenosine triphosphate enzyme (ATPase)
9. The nurse would be correct in identifying the predominant extracellular
cation as: - Correct Answer Answer: Sodium
10.The early dilation (swelling) of the cell's endoplasmic reticulum results in: -
Correct Answer Answer: Reduced protein synthesis
11.What principle should the nurse remember when trying to distinguish aging
from diseases? - Correct Answer Answer: It is difficult to tell the difference
because both processes are believed to result from cell injury.
12.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. - Correct
Answer Answer: Turner syndrome
13.A eukaryotic cell is undergoing DNA replication. In which region of the cell
would most of the genetic information be contained? - Correct Answer
Answer: Nucleolus
14.The nurse is teaching staff about the most common cause of Down
syndrome. What is the nurse describing? - Correct Answer Answer:
Maternal nondisjunction
