Write answer in between .Q:An 82-year-old male with congestive heart failure experiences rapid decompensation of his condition, manifesting as worsening dyspnea, edema, and increased fatigue. Labs reveal an increase in his serum creatinine from baseline. As part of the management of this acute change, the patient is given IV dobutamine to alleviate his symptoms. Which of the following effects occur as a result of this therapy?? A: Slowed atrioventricular conduction velocities, B: Increased myocardial oxygen consumption, C: Decreased heart rate, D: Increased systemic vascular resistance due to systemic vasoconstriction, E: Decreased cardiac contractility,  <response>: This is a question about the effects of dobutamine in a patient with congestive heart failure. Dobutamine is a sympathomimetic drug that acts on beta-1 adrenergic receptors to increase cardiac contractility and heart rate. It is used to treat acute decompensated heart failure to improve cardiac output. The key points in the question stem are:- 82-year-old male with congestive heart failure - Experiencing acute decompensation with worsening symptoms- Given IV dobutamine to alleviate symptomsThe choices describe various cardiovascular effects. We need to identify which one is the expected effect of dobutamine based on its mechanism of action.B: Increased myocardial oxygen consumption
