MIDTERM ADVANCED PRACTICE CARE OF ADULTS
ACROSS| ALL 150 QUESTIONS AND CORRECT
ANSWERS
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
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.
A 12-year-old male is diagnosed with Klinefelter syndrome. His karyotype would reveal which of the
following? - CORRECT ANSWER-Answer: XXY
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
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
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.
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
,How are potassium and sodium transported across plasma membranes? - CORRECT ANSWER-
Answer:
By adenosine triphosphate enzyme (ATPase)
myocarditis - CORRECT ANSWER-inflammation of the myocardium with necrosis of cardiac myocytes
biopsy shows inflammatory infiltrate of the myocardium with lymphocytes, neutrophils, eosinophils, and
granulomas
direct cardiomyocyte injury cased by an infectious or other cardiotoxic agent OR myocardial injury
caused by an autoimmune reaction to an infectious or cardiotoxic agent
aortic regurgitation - CORRECT ANSWER-(aortic insufficiency) incompetent aortic valve that allows
backward flow of blood from the aorta into left ventricle during diastole
aortic stenosis - CORRECT ANSWER-calcification of aortic valve cusps that restricts forward flow of
blood during systole
narrowing of the aortic valve, obstructing blood flow from the left ventricle to the ascending aorta during
systole
mitral regurgitation - CORRECT ANSWER-mitral insufficiency; incompetent mitral valve allows
regurgitation of blood from the left ventricle back into left atrium during systole
mitral stenosis - CORRECT ANSWER-narrowing of the mitral valve orifice that impedes blood flow
from the left atrium to the left vetricle
mitral valve prolapse - CORRECT ANSWER-Improper closure of the valve between the heart's upper
and lower left chambers.
, billowing of mitral valve leaflets into the left atrium during systole
pulmonic regurgitation - CORRECT ANSWER-pulmonic insufficiency; backflow of blood through
incompetent pulmonic valve into the right ventricle
causes blood from from the pulmonary artery into the right ventricle during diastole
pulmonic stenosis - CORRECT ANSWER-narrowing of the opening and valvular area between the
pulmonary artery and right ventricle
narrowing of the pulmonary outflow tract causing obstruction of blood flow from the right ventricle to
the pulmonary artery during systole
deep vein thrombosis - CORRECT ANSWER-blood clot forms in a large vein, usually in a lower limb
d/t impaired venous return, endothelial injury or hypercoagulability
thrombi - CORRECT ANSWER-__ consist of thrombin, fibrin, and red blood cells with few platelets
and without treatment can travel to the lungs causing PE
Hypertension - CORRECT ANSWER-high blood pressure sustained SBP >130
BP= cardiac output x total peripheral vascular resistance (TPR)
HTN leads to ↑ CO, ↑ TPR
peripheral artery disease - CORRECT ANSWER-Atherosclerotic disease of the arteries that perfuse
the limbs especially the lower extremites.
can cause intermittent claudation and may not be painful and can go undetected for years.
