Answer to Question 1

1
In adjusted dosing, the standard heparin IV dose is used initially, but subsequent dose adjust-ments are based on raising the aPTT 2 to 5 seconds above normal level.

Answer to Question 2

3
To divide by 200, or by 200/1, simply invert or reverse the numerator (200) and the denominator (1) and multiply by the result, or by 1/200. 200 = 200/1 = x 1/200 = x 200 =1/400.
