A patient in cardiogenic shock has cool clammy skin, a low cardiac output and severe hypotension despite adequate fluid replacement. Which medicine may be used to improve cardiac contractility?
Correct answer: A. Dobutamine
- A. Dobutamine
- B. Furosemide
- C. Lidocaine
- D. Adenosine
Explanation
Dobutamine is an inotropic medicine that increases myocardial contractility and can improve cardiac output in cardiogenic shock. Furosemide reduces fluid overload, while lidocaine and adenosine treat selected cardiac rhythm problems rather than low contractility.
