Question 1 of 5
A patient asked the nurse what cardiac glycosides do to improve his condition. What is the nurse's best response?
Correct Answer: D
Rationale: The correct answer is D because cardiac glycosides, such as digoxin, help improve heart failure by increasing renal blood flow and urine output. This occurs by inhibiting the sodium-potassium pump, leading to increased intracellular calcium levels, which in turn enhances cardiac contractility and renal perfusion.
Choices A, B, and C are incorrect because cardiac glycosides do not increase heart rate, decrease the force of myocardial contractions, or decrease conduction velocity. These medications actually have a positive inotropic effect, increasing the force of myocardial contractions.
