A patient asks the nurse what cardiac glycosides do to improve his condition. What is the nurse's best response?
A) "They decrease the force of myocardial contractions."
B) "They help renal blood flow and increase urine output."
C) "They increase heart rate."
D) "They increase conduction velocity."
B
Feedback:
Cardiac glycosides increase intracellular calcium and allow more calcium to enter myocardial cells. This action causes an increased force of myocardial contraction, an increased cardiac output, and renal perfusion that increases urine output. Cardiac glycosides also serve to slow the heart rate and decrease conduction velocity.
