The nurse is evaluating the medical prescription of carvedilol 6.25 mg PO daily for a client with a history of unstable angina. Which of the following reflects that the medication's action has been effective?

Urine output 50 mL per hour

Heart rate 60 beats/minute

Heart rhythm regular

Blood pressure 120/90

Answer and Explanation

The Correct Answer is B

A. While it may have some impact on kidney function indirectly through its effects on blood pressure and heart function, urine output is not the primary parameter used to assess the effectiveness of carvedilol in a patient with a history of unstable angina.
B. Carvedilol, as a beta-blocker, helps reduce heart rate by blocking the effects of adrenaline on the heart. In unstable angina, lowering the heart rate can reduce myocardial oxygen demand, which is beneficial in managing ischemic symptoms
C. Carvedilol primarily affects heart rate and blood pressure but doesn't directly regulate heart rhythm. However, in patients with certain cardiac conditions, like heart failure or left ventricular dysfunction after a heart attack, carvedilol can sometimes help to stabilize heart rhythm indirectly by reducing stress on the heart.
D. Carvedilol is also effective in reducing blood pressure, which is beneficial in patients with unstable angina, as it decreases the workload on the heart and the oxygen demand of the myocardium. A blood pressure reading of 120/90 is within the normal range for an adult and indicates good control of blood pressure.
