Exam 19: Heart Failure and Dysrhythmias: Common Sequelae of Cardiac

A laboratory test that should be routinely monitored in patients receiving digitalis therapy is

$\beta$ -Adrenergic blocking drugs are contraindicated in heart failure.

Right-sided heart failure usually is a consequence of

A patient who complains of dizziness and who has absent P waves, regular QRS complexes, and a heart rate of 48 beats/min on an ECG is most likely in which rhythm?

The majority of dysrhythmias are believed to occur because of

Angiotensin-converting enzyme (ACE) inhibitor therapy is avoided in heart failure because a drop in preload may reduce cardiac output.

Left-sided heart failure is characterized by

A patient receives an ACE-inhibiting agent to manage his cardiovascular disease. Which of the following is not an expected result of ACE inhibitor therapy?

The overall 5-year survival rate after onset of heart failure is about 50%.

A patient with pure left-sided heart failure is likely to exhibit

Systolic failure is associated with a low cardiac output and low ejection fraction.

Morphine and nitrates may be used in the management of acute pulmonary edema to

The principal difference between systolic failure and diastolic failure is the ejection fraction.
