No, this is the exact question: A client is hospitalized with a dx of atrial fib. Heparin 5,000 units is ordered every 12 hours to be given subQ. The physician orders daily PTTs. The result of the client's most recent PTT is 55. Which of the following actions should be taken by the nurse? 1. Document the results and administer the heparin. This is the answer it says because 55 is not 1.5-2 times the normal, so the med should be given. It says normal PTT is 20-45 seconds.

What is the therapeutic range for heparin, in terms of PTT? I thought it was 1.5-2 times the normal range of PTT. The normal range of PTT is 20-45 seconds right? So the therapeutic range would be 30-90? Am I thinking through this correctly? The Kaplan book is saying 55 seconds is not in therapeutic range.
