Steady state concentration answer

Correct answer is option a

the steady state concentration of a drug is directly proportional to the infusion rate.

increasing the loading dose provides a transient increase in drug level but the steady state level remains unchanged.

doubling both the rate of infusion and the concentration of infused drug leads to a four fold increase in the steady state concentration of the drug

tripling or quadrupling the rate of infusion leads to either or three or four increase in the steady state drug concentration
