Correct answer: C — Start therapeutic anticoagulation while awaiting confirmatory imaging if bleeding risk is low

When clinical probability is high and imaging is delayed, start therapeutic anticoagulation if bleeding risk is low. Waiting risks embolization. Prophylactic dosing is inadequate. D-dimer alone is not sufficient with high probability. Compression alone is inappropriate.
