Insulin Flashcards
T/ F
the beta cells in the islets of Langerhans secrete insulin
T
pancreatic acini
A. Exocrine
B. Endocrine
A
digestive enzymes
A. Exocrine
B. Endocrine
A
islets of Langerhans
A. Exocrine
B. Endocrine
B
glucagon, insulin
A. Exocrine
B. Endocrine
B
somatostatin, gastrin
A. Exocrine
B. Endocrine
B
pancreatic polypeptide
A. Exocrine
B. Endocrine
B
T/F
insulin inhibits glucose production
T
T/ f
glucagon is produced by the alpha cells in the islets of
Langerhans and opposes the action of insulin
T
T/ F
insulin promotes protein and lipid metabolism
T
T/ F
insulin receptors are G-protein coupled receptors and need second messengers (tyrosine kinase)
T
insulin-dependent
A. Type I
B. Type II
C. Type III
D. Type IV
A
juvenile onset
A. Type I
B. Type II
C. Type III
D. Type IV
A
selective beta cell destruction & severe or
absolute insulin deficiency (hallmark)
A. Type I
B. Type II
C. Type III
D. Type IV
A
cannot be given oral hypoglycemics
A. Type I
B. Type II
C. Type III
D. Type IV
A
can be triggered by invasion of viruses or by
chemical toxins
A. Type I
B. Type II
C. Type III
D. Type IV
A
shows classic symptoms:
o polydipsia
o polyphagia
o polyuria
o weight loss
A. Type I
B. Type II
C. Type III
D. Type IV
A
maturity onset
A. Type I
B. Type II
C. Type III
D. Type IV
B
not insulin-dependent
A. Type I
B. Type II
C. Type III
D. Type IV
B
tissue resistance to the action of insulin combined with relative deficiency of insulin
A. Type I
B. Type II
C. Type III
D. Type IV
B
other causes:
o pancreatitis
A. Type I
B. Type II
C. Type III
D. Type IV
C
gestational diabetes
A. Type I
B. Type II
C. Type III
D. Type IV
D
occurs during the third trimester of
pregnancy
A. Type I
B. Type II
C. Type III
D. Type IV
D
T/ F
it is important to treat first the other diseases, such as hypertension, because most often they coincide together like in the Big Three: hypertension, high cholesterol levels, and diabetes
T
secretion is most commonly triggered by increase in blood glucose
INSULIN
T/ F
insulin binds to receptors found in the target tissues such as liver, muscle, adipose tissue
T
permit more physiologic prandial insulin replacement because their rapid onset & early peak action more closely mimic normal endogenous prandial insulin secretion
A. RAPID-ACTING INSULIN (INSULIN LISPRO)
B. SHORT-ACTING INSULIN (REGULAR INSULIN)
C. INTERMEDIATE-ACTING INSULIN (NEUTRAL PROTAMINE HAGEDORN INSULIN)
D. LONG-ACTING INSULIN
A
→ preferred insulin for use in continuous subcutaneous insulin infusion devices
→ administered prior to a meal

C. INTERMEDIATE-ACTING INSULIN (NEUTRAL PROTAMINE HAGEDORN INSULIN)
D. LONG-ACTING INSULIN
A
→ given 30-45 minutes before a meal
→ only type that should be administered IV
