[2025-10-02T03:03:51.867818] [PI reasoning] **Analyzing heparin use for prophylaxis**

I’m looking at a question about the most common route of heparin administration for post-operative thromboprophylaxis. It’s clear that subcutaneous injection is the standard method, particularly for low-dose unfractionated heparin or low molecular weight heparin administered every 8-12 hours. Intravenous might be used for immediate needs, but IM is out due to hematoma risk. So, I’ll conclude the answer is A and include some reasoning and citation from relevant guidelines.
