- A. Request STAT arterial blood gases.
- B. Administer lidocaine intravenous push.

A patient is receiving continuous IV Heparin for anticoagulation therapy for the treatment of a DVT. In order for this medication to have a therapeutic effect on the patient, the aPTT should be?
- A. 0.5-2.5 times the normal value range
- B. 2-3 times the normal value range
- C. 1.5-2.5 times the normal value range
- D. 1-3.5 times the normal value range
Correct Answer: C
Rationale: An aPTT should be 1.5-2.5 times the normal value range for Heparin to achieve a therapeutic effect in a patient to prevent blood clots. If the aPTT is too low, blood clots can form. If the aPTT is too high, bleeding can occur.
