What will be an ideal response?

A 73-year-old male presents with confusion; cool, pale, clammy skin; absent radial pulses; and a blood pressure of 70/40 mm Hg. The patient's wife tells you that he has had abdominal pain for a week and began vomiting a coffee-ground substance yesterday. His past medical history includes hypertension and gastric ulcer disease. Your MOST immediate concern should be that:

A: his blood glucose level is probably too high. B: his condition requires surgery within 2 hours. C: he is bleeding from his gastrointestinal tract. D: he is in shock and requires prompt transport.
