A nurse is assessing a client who is receiving a continuous IV infusion of dopamine. Which of the following findings should the nurse recognize as a therapeutic effect?

Decreased dysrhythmias

Increased urine output

Increased pulse

Decreased blood pressure

Answer and Explanation

The Correct Answer is B

A.   While dopamine can be used to treat some types of dysrhythmias, the primary therapeutic goal of a continuous IV infusion of dopamine is not to decrease dysrhythmias but to increase blood flow to vital organs.
B.   Increased urine output is a sign that dopamine is effectively improving renal perfusion, which is one of its therapeutic effects. Dopamine stimulates renal blood flow, helping the kidneys excrete more urine.
C.   An increase in pulse is a possible side effect of dopamine but is not considered a therapeutic effect. The therapeutic goal of dopamine is to improve perfusion, not necessarily to increase heart rate.
D.   Dopamine typically causes vasodilation in lower doses and vasoconstriction in higher doses, which can lead to increased blood pressure, not decreased. It is more likely to raise blood pressure rather than lower it.
