The nurse is caring for a patient with diabetic ketoacidosis. As part of the treatment plan, which action should the nurse take first?

Initiate fluid replacement.

Explanation

• Fluid replacement is a priority in order to prevent vascular collapse due to severe dehydration

• Insulin administration is important, but hydration is the priority

• Determining the cause or trigger is important, but fluid resuscitation is the priority

• Administering potassium may be needed after insulin therapy is initiated, but this is not a priority at this time. Insulin transports potassium into the cell, potentially causing hypokalemia
