23:  Co-Existing Disease:  Diabetes Practice Questions
 
 
- Most common complication insulin therapy: -   lipodystrophies
-   hypotension
-   gallstones
-   hypoglycemia
-   retinopathy
 
- Effects associated with insulin- induced hypoglycemia: -   tachycardia
-   palpitations
-   nausea
-   sweating
-   all of the above
 
- Effective in the immediate management of the comatose, hypoglycemic patient. -   have the patient drink orange juice
-   provide IV infusion of 50% glucose solution
-   glucagon injection -- subcutaneous or intramuscular
-   B & C
-   A,B & C
 
- Causes of hypoglycemia in a diabetic patient: -   insulin overdosage
-   delay in eating (later than normal)
-   unusual physical activity
-   A & B
-   A,B & C
 
- Blockade of signs of diabetic hypoglycemia: -   diabetic neuropathy
-   metoprolol (Lopressor)
-   propranolol (Inderal)
-   B & C
-   A, B & C
 
- Insulin allergy: -   immediate response is IgG mediated
-   anaphylaxis may result
-   change in insulin species(e.g. from pure pork or human from beef)
-   B & C
-   A, B & C
 
- Biguanide-- oral hypoglycemic drug: -   Tolbutamide (Orinase)
-   acarbose (Precose)
-   metformin (Glucophage)
-   troglitazone (Rezulin)
-   none of the above
 
- Proposed mechanism(s) for hypoglycemic action of sulfonylureas: -   enhancement of insulin release from pancreatic beta cells
-   increase of serum glucagon levels
-   potentiation of insulin effects at target tissues
-   A & B
-   A & C
 
- Sulfonylurea hypoglycemic drug:receptor sites -   muscarinic receptor
-   calcium channel
-   potassium channel
-   beta adrenergic receptor
-   alpha adrenergic receptor
 
- Inhibitors of insulin release: -   somatostatin
-   diazoxide (Hyperstat)
-   phenytoin (Dilantin)
-   vinblastine (Velban)
-   all of the above
 
- Second generation sulfonylurea: -   chlorpropamide (Diabinese)
-   tolazamide (Tolinase)
-   acetohexamide
-   glipizide (Glucotrol)
-   Tolbutamide (Orinase)
 
- Second-generation sulfonylurea approved for once-daily use as monotherapy in management of Type II diabetes: -   chlorpropamide (Diabinese)
-   glyburide (Micronase, DiaBeta)
-   glipizide (Glucotrol)
-   glimepiride (Amaryl)
-   metformin (Glucophage)
 
- Oral hypoglycemic agent most likely to be prescribed for patients with refractory obesity and who exhibit insulin resistance syndrome: in -   acetohexamide
-   chlorpropamide (Diabinese)
-   glyburide (Micronase, DiaBeta)
-   metformin (Glucophage)
-   Tolbutamide (Orinase)
 
- Aldose reductase inhibitor: -   metformin (Glucophage)
-   acetazolamide (Diamox)
-   Tolbutamide (Orinase)
-   acarbose (Precose)
-   troglitazone (Rezulin)
 
- Cardiac effects of glucagon: -   positive inotropic; positive chronotropic
-   negative inotropic negative chronotropic
 
- Immediate pharmacologic/metabolic consequence of glucagon infusion: -    increase hepatic glycogen; decrease blood glucose
-   decrease blood glucose; decrease stored hepatic glycogen
-   increased blood glucose; decreased hepatic glycogen
-   decreased blood glucose; increase stored hepatic glycogen
-   none of the above
 
- Glucagon effect(s)-- at pharmacologic doses: -   promote insulin release from normal pancreatic B cells
-   promote catecholamine release from pheochromocytoma
-   promote calcitonin release from medullary carcinoma cells
-   A & B
-   A, B & C
 
- Following very significant alpha and beta-adrenergic blocker overdosage; most likely to promote increased inotropic and chronotropic cardiac response -   isoproterenol (Isuprel)
-   phenylephrine (Neo-Synephrine)
-   glucagon
-   mecamylamine (Inversine)
-   none of the above would be effective
