What is the nebulized dose range of Albuterol for hyperkalemia?

• A. 0.5 mg nebulized
• B. 2.5 to 10 mg nebulized
• C. 15 mg nebulized
• D. 2.5 mg inhaled once

Answer: (B)

In hyperkalemia, nebulized albuterol lowers serum potassium by stimulating beta-2 receptors and driving potassium into cells via the Na+/K+-ATPase pump. Because you need a rapid and meaningful shift, the dose given by nebulization is higher than what’s used for bronchospasm. The accepted range is 2.5 to 10 mg per nebulization, with clinicians often repeating doses to reach about 10 mg total while watching for side effects like tachycardia or tremor. A much smaller dose, such as 0.5 mg, is unlikely to produce a clinically significant potassium drop. A single 15 mg nebulized dose goes beyond typical practice and increases risk without clear extra benefit. An inhaled 2.5 mg dose (not nebulized) wouldn’t provide the higher, rapid effect sought in hyperkalemia management.
