|Questions and Answers With 100% Correct
Solutions | A+ Grade
A runner has depleted all the oxygen available for muscle energy. Which of the
following will facilitate his continued muscle performance? >> CORRECT ANS
>>Anaerobic glycolysis
What causes the rapid change in the resting membrane potential that initiates an
action potential?
>> CORRECT ANS >>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? >> CORRECT ANS >>XXY
A nurse is reviewing the pedigree chart. When checking for a proband, what is the
nurse looking for?
>> CORRECT ANS >>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? >> CORRECT ANS >>Expressivity
In teaching a patient with cirrhosis, which information should the nurse include
regarding cholesterol?
>> CORRECT ANS >>Cholesterol decreases the membrane fluidity of the
erythrocyte, which reduces its ability to carry oxygen.
When a patient asks what causes cystic fibrosis, how should the nurse respond?
Cystic fibrosis is caused by a gene >> CORRECT ANS >>Autosomal recessive
, How are potassium and sodium transported across plasma membranes? >>
CORRECT ANS >>By adenosine triphosphate enzyme (ATPase)
The nurse would be correct in identifying the predominant extracellular cation as:
>> CORRECT ANS >>Sodium
The early dilation (swelling) of the cell's endoplasmic reticulum results in: >>
CORRECT ANS >>Reduced protein synthesis
What principle should the nurse remember when trying to distinguish aging from
diseases? >> CORRECT ANS >>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. >> CORRECT ANS >>Turner syndrome
A eukaryotic cell is undergoing DNA replication. In which region of the cell would
most of the genetic information be contained? >> CORRECT ANS >>Nucleolus
The nurse is teaching staff about the most common cause of Down syndrome.
What is the nurse describing? >> CORRECT ANS >>Maternal nondisjunction
A 50-year-old male was recently diagnosed with Huntington disease. Transmission
of this disease is associated with: >> CORRECT ANS >>Delayed age of onset
A patient wants to know the risk factors for Down syndrome. What is the nurse's
best response?
