 PLOT: The herpetologist, Dr. Price, is shown giving medical  directions to the paramedics when the passengers are coming off of  the aircraft to be treated. He is identified as "the leading snake  expert in the area", so most likely he would hold a PhD in the  subject, and not an M.D. If he is in fact an M.D., he is shown to  call out for "Lactine and Ringers solution" to be administered. The  actual term is either "Ringers Lactate" or "Lactated Ringers  solution". This is a standard and common IV solution, and an M.D.  would never make a mistake in something as common as that.
