A patient is on a low-dose dobutamine drip for heart failure. She had been feeling better but now has a sense of tightness in her chest, palpitations, and a bit of anxiety. Her heart rate is up to 110 beats/min, and her blood pressure is 150/98 mm Hg (increased from previous readings of 86 beats/min and 120/80 mm Hg). What is the nurse’s immediate concern for this patient?


▸ She is experiencing normal adverse effects of dobutamine therapy.

▸ She may be experiencing an allergic reaction to the dobutamine.

▸ The medication may be causing a worsening of a preexisting cardiac disorder.

▸ The dosage of the dobutamine needs to be increased to control the symptoms better.

The medication may be causing a worsening of a preexisting cardiac disorder.

Because dobutamine is a vasoactive adrenergic, it works by increasing the cardiac output in heart failure patients by increasing myocardial contractility and stroke volume. However, adrenergic drugs may worsen a preexisting cardiac disorder, such as causing a myocardial infarction in a patient with coronary artery disease. The other options are incorrect.
