Rationale 1:Norepinephrine (Levophed) activates alpha and beta1 adrenergic receptors causing profound vasoconstriction.
Rationale 2:Norepinephrine (Levophed) activates alpha and beta1 adrenergic receptors causing increased blood pressure, force of contraction, and cardiac output.
Rationale 3:Norepinephrine (Levophed) does not increase urine output.
Rationale 4:Antidysrhythmics are not used to treat shock.

Global Rationale: The body's ability to compensate during shock is limited, so vasoconstrictors are used to maintain blood pressure. Norepinephrine (Levophed) activates alpha and beta1 adrenergic receptors causing an increase of blood pressure, force of contraction, and cardiac output.
