A nurse in the emergency department is admitting a client who has diabetic ketoacidosis and a blood glucose level of 800 mg/dL.
Which of the following interventions should the nurse initiate first?
Subcutaneous insulin injections.
Bicarbonate by IV infusion.
0.9% sodium chloride 15 m/kg/hr.
Potassium chloride 10 mEq/hr.
The Correct Answer is C
The first intervention for a client with diabetic ketoacidosis and a blood glucose level of 800 mg/dL should be to initiate fluid replacement therapy with 0.9% sodium chloride at a rate of 15 mL/kg/hr.
This will help to replace fluids lost through excessive urination and to dilute the excess sugar in the blood.
Choice A is wrong because subcutaneous insulin injections are not the first intervention for diabetic ketoacidosis.
Insulin therapy is generally given intravenously.
Choice B is wrong because bicarbonate by IV infusion is not the first intervention for diabetic ketoacidosis.
Choice D is wrong because potassium chloride at a rate of 10 mEq/hr is not the first intervention for diabetic ketoacidosis.
Electrolyte replacement may be necessary to replace minerals such as sodium, potassium, and chloride, but this is not the first intervention 2.
