The Correct Answer is ["0.4"]
To calculate the amount of heparin to administer, use the formula:
mL of heparin=units available units ordered×1mL available
Substituting the values given in the question, we get:
mL of heparin=100004000×11=0.4
Therefore, the nurse should administer 0.4 mL of heparin.
Normal ranges for heparin therapy vary depending on the condition being treated and the laboratory method used to measure APTT.
A general range is 60 to 80 seconds or 1.5 to 2.5 times the control value.
