A patient has been diagnosed with an irregular heartbeat. The nurse realizes that the impulse for a heartbeat originates in the sinoatrial node in response to which of the following electrolytes?
1. potassium
2. calcium
3. phosphorus
4. sodium
4
Rationale: The pacemaker cells in the sinoatrial node have a constant influx of sodium. Calcium is the electrolyte that is needed for a well-functioning plateau phase of the cardiac cycle. Potassium is the main intracellular electrolyte. Phosphorus is not an electrolyte that is integral to a well-functioning cardiac cycle.
