Ned sits down on the end of the hospital bed and tells Dr. snow to stop asking about the propranolol he takes every day for his migraine because he has chest pain.
dr snow ( foolishly) decides Ned must have PTSD from being a war veteran and google "PTSD in old men" on his smartphone. a user called "DoctorFromOhio" on www.reddit.com suggests alpha-blockers are good for PTSD. Dr Snow shrugs, gives Ned a dose of IV terazosin, and turns away to type into the hospital computer. Moments later Ned fails to the floor on his face, unconscious.
Dr. snow immediately checks Ned pulse. What happens?
(stop! only about 1/5 students get this question correct. figure it the Bp change due to the IV terazosin in this patient who is already taking propranolol, then determine the heart rate reflex to see if it changed from 60 beats per minute.
what is Ned heart rate when Dr snow check it?
