The nurse is attempting to increase contractility to improve cardiac output in a patient with acute exacerbation of heart failure. Which measure would be helpful to improve cardiac contractility?

Question

Quizplus · Accepted Answer

Correcting oxygenation and mild respiratory acidosis can improve contractility by increasing oxygen delivery to the myocardium and decreasing acidosis, which can impair contractility. Administering magnesium sulfate can also improve contractility, but it is not the most helpful measure in this situation. Encouraging the patient to exercise and giving beta-adrenergic blocking medication can have negative effects on contractility in a patient with heart failure.
