Thirty minutes later, he develops dyspnea, severe muscle pain, vomiting, and sinus tachycardia; his blood pressure is 80/40mmHg. Which of the following hematopoietic growth factors most likely caused these new findings?
A) Erythropoietn

why did u pick 2) D ? might as well pick B if its just a guess ? ..
Neverming i just googled and its B, i guess thats just the side affect ?
And winnera #3 can not be A because " He tries to avoid making the presentations " . Phobia interferes with normal function. Stress is just stress like step 1 =(
