Question

An explorer is infected with Ebola Virus. The person bleeds into his interstitial space and has low blood volume returning to the heart. This will cause the heart to have?

a) Increased strength of contraction

b) Decreased heart rate

c) Decreased strength of contraction

d) A very high blood pressure

Answer 1

The right answer depends on how you define "strength of contraction."

If 'strength of contraction' is taken to mean 'cardiac output,' it will be C.

If you take 'strength of contraction' to mean, literally, the force with which the heart beats, it will be A.
