ANSWER B.

This patient is suffering from acute radiation syndrome. The rapid onset of his gastrointestinal symptoms suggests a life-threatening dose of radiation. In acute radiation sickness, the earlier the onset of this prodromal phase, the greater the likely exposure. The most commonly used method of estimating dose exposure and prognosis is the Andrews lymphocyte depletion curves, which examines the level of lymphocyte decline over 48 hours.

Acute radiation syndrome is often accompanied by a hematopoietic syndrome with pancytopenia, infection, and hemorrhage commonly occurring. However, it is the lymphocyte count at 48 hours that best predicts the patient’s course.

Measuring iodine levels (A) has no prognostic value. Monocytes (C) and platelets (D) typically decline over the course of weeks.

Thanks for your effort. Nice to review uncommon diseases to keep us up to speed. It is amazing how many diseases, pathogens etc... have had their names changed : Granulomatosis with Polyangiitis (GPA) (formerly referred to as Wegener’s granulomatosis) .
