QUESTIONS AND CORRECT
ANSWERS
What should a fasting blood glucose be?
70-100mg/dL
What should a postprandial blood glucose be?
It should not exceed 180mg/dL
Glycated Hemoglobin A1C measures blood glucose for how many months?
It checks the blood glucose for the past 3-4 months (120 days)
What is a normal A1C for a non-diabetic?
< 5.4-5.6%
What is a normal A1C for a diabetic?
< 6.5%
,A calculator of the difference between measurable extracellular plasma
cations (Na+ & K+) and the measurable anions (Cl- & HCO3-) is called?
a. the Ketotic cycle
b. Hyperosmotic filtration
c. Anion Gap
d. Nephrogenic filtration
c. Anion Gap
A calculator of the difference between measurable extracellular plasma
cations (Na+ & K+) and the measurable anions (Cl- & HCO3-) is the anion
gap
What does the anion gap represent?
a. represents the measurable amount of ions present in the extracellular fluid
b. represents the unmeasurable ions present in ht extracellular fluid
c. represents the measurable of ions present in the intracellular fluid
d. represents the unmeasurable of ions present in the intracellular fluid
b. represents the unmeasurable ions present in ht extracellular fluid
What is a normal anion gap range?
8-16 mEq/L
What is a High Anion Gap? What does this represent?
> 18 is high
,It indicates metabolic acidosis. It effects over production or decreased
exertion of acid products
What is a Low Anion Gap? What does this represent?
< 8 is low
It indicates Metabolic Alkalosis
Islets of Langerhans is groups of pancreatic cells secreting insulin and
glucagon from the pancreas. What are the names of the cells?
Alpha Cells
Beta Cells
Delta Cells
PP Cells
Which organ is involved in Glucose metabolism?
a. stomach
b. liver
c. intestines
d. pancreas
d. pancreas
The pancreas is involved in Glucose Metabolism
, What do alpha cells excrete?
a. pancreatic polypeptide
b. insulin
c. glucagon
d. somatostatin
c. glucagon
Glucagon (released when sugar levels are low, released from the liver to
raise blood glucose levels). This is done through Gluconeogenesis from non-
carbohydrates (proteins & fat
What do beta cells secrete?
a. pancreatic polypeptide
b. insulin
c. glucagon
d. somatostatin
b. insulin
Insulin (responsible for storage of carbohydrates, protein, fat, helps transport
potassium into cells too, helps lower blood glucose).
What do delta cells secrete?
