Answer to Question 1

ANS: D
6 Dextran 75 is a high molecular-weight colloidal solution and is used to treat shock from burns or trauma. Colloids are plasma expanders, and the end result is an improvement in heart rate (decreased) and blood pressure (increased). Plasma expanders will result in an increase in urine output. Blood oxygenation is not affected, and colloids do not increase the amount of interstitial fluid.

Answer to Question 2

ANS: C
Large doses of chromium can cause a hypoglycemic reaction in patients taking insulin or oral antidiabetic agents. Normal doses are thought to be helpful in diabetic control. It does not increase the risk for ketoacidosis. The normal dose is 50-200 mcg/day.
