Your best response to this is to tell her: A. that she is likely to damage her kidneys if she maintains this diet plan B. that her protein intake is good, as protein increased the effect of levodopa C. that protein in her diet will benefit the transport of levodopa throughout her body D. that too much dietary protein could make the levodopa less effective

D. that too much dietary protein could make the levodopa less effective

A nursing professor is teaching a class about a medication that alters the parasympathetic nervous system functions.
