A nurse inadvertently allows an IV solution containing potassium to infuse too rapidly. The health care provider prescribes insulin added to a 10% dextrose in water solution. What is the rationale for the order?
1
Potassium moves into body cells with glucose and insulin.
2
Increased insulin accelerates excretion of glucose and potassium.
3
Glucose with insulin increases metabolism, which accelerates potassium excretion.
4
Increased potassium causes a temporary slowing of pancreatic production of insulin.
