A 69-year-old female was involved in a motor vehicle crash. she is semiconscious with a blood pressure of 80/50 mm hg and a hear
t rate of 74 beats/min that is weak. her daughter, who was uninjured in the crash, tells you that her mother has a history of hypertension and takes beta-blockers. considering the fact that this patient is probably in shock, what is the most likely explanation for the absence of tachycardia?
From the information here, it clearly says she has hypertension and takes beta-blockers, so the explanation for the absence of tachycardia would result from her medication.
