Question

A blood pressure reading of 80/50 mm of mercury could be a symptom of 

A. rapid blood loss

B. anger

C. narrowing of the arteries

D. extremely strenuous exercies

Answer 1

A. Rapid blood loss. That's a low BP reading; the other three options would increase pressure. Keep in mind: you need fluid (in this case blood) to exert pressure. No blood = low pressure exerted on the vessels.
