A client asks the nurse, “I was told that my heart is beating in normal sinus rhythm (NSR). What does that mean?” The nurse replies most therapeutically when responding with which of the fol-lowing?

1. “Are you worried about how your heart is working?”
2. “It means your heart is working just the way it is supposed to work.”
3. “A damaged heart doesn’t beat in normal sinus rhythm like yours does.”
4. “Each beat starts in the SA node and then causes the chambers to contract.”

ANSWER

ANS: 4
NSR implies that the impulse originates at the SA node and follows the normal sequence through the conduction system.
