الإجابة: B. Switch to theraputic enoxaparin does
A confirmed DVT that develops on prophylactic-dose LMWH needs treatment-dose anticoagulation, so the enoxaparin is switched to the therapeutic dose (1 mg/kg SC BID or 1.5 mg/kg daily).
- Continuing the prophylactic dose (A) under-treats an established clot.
- Warfarin alone (D) is not suited to acute DVT therapy: its effect is delayed, so it needs parenteral bridging.
- Changing to fondaparinux (C) offers no advantage over simply escalating the LMWH dose.

C
ليش غلط
Fondaparinux acts like enoxaparin (a parenteral indirect anticoagulant that increases antithrombin), so it adds no new mechanism; the enoxaparin simply needs a treatment dose.

D
ليش غلط
Warfarin alone is slow: its effect begins after 4-5 days, so a concurrent heparin bridge is needed if immediate anticoagulation is required.
