Hyperkalemia part 3

What does calcium chloride do?

• Lowers serum potassium

• Transports potassium back into cell

• Lowers resting membrane potential

• Changes blood pH

How does sodium bicarbonate affect serum potassium?

• Utilizes acid-base buffer system to shift potassium into cells

• Lowers resting membrane potential

• Absorbs potassium

• Utilizes Na-K pump to shift potassium into cells

What must be done when administering insulin to treat hyperkalemia? (best answer)

• Monitor blood pressure and heart rate

• Provide a sandwich

• Slow drip IV D10 or D5

• Push full amp of D50

How does albuterol reduce serum potassium levels?

• Utilizes the acid-base buffer system

• Lowers resting membrane potential

• Activates Na-K pump

• Slows cardiac conduction

What is typically regarded as a last resort for treatment of hyperkalemia?

• Albuterol

• Metoprolol

• Calcium gluconate

• Hemodialysis

• Furosemide
