Which stat order for Mr. Palmer should the nurse question given his current heparin therapy?

  1. Computed tomography (CT) angiogram.

  2. Enoxaparin (Lovenox) 40 mg subcutaneously.

  3. Oxygen per nasal cannula at 4 L per minute.

  4. Troponin level.

The correct answer is: Enoxaparin (Lovenox) 40 mg subcutaneously.

Given that Mr. Palmer is currently receiving heparin therapy, the nurse should question the order for Enoxaparin (Lovenox) 40 mg subcutaneously. Enoxaparin is also an anticoagulant, like heparin, and giving both medications together can increase the risk of bleeding. It is essential to avoid duplicate therapy with anticoagulants to prevent complications. The other options - CT angiogram, oxygen per nasal cannula at 4 L per minute, and troponin level - are appropriate in the context of Mr. Palmer's condition and do not pose a risk of duplicating anticoagulant therapy.
