The correct option is A: Dobutamine decreases peripheral resistance. Explanation: Ref: HL Sharma 3rd ed pg no: 177 Dobutamine is a derivative of dopamine and is a selective beta1 agonist. It causes an increase in the force of contraction without a significant increase in hea rate. It also produces some vasodilatation by stimulating the beta 2 receptors. It doesn't decrease kidney circulation.<|im_end|>
