Place the prescribed treatment actions in order for an adult with diabetic ketoacidosis and an initial potassium of 3.1 mmol/L.

Explanation
Stabilize and monitor first, then begin isotonic fluid resuscitation while obtaining studies. Because potassium is 3.1 mmol/L, replace potassium and delay insulin until it is above 3.5 mmol/L. Then start IV insulin. Continue frequent glucose, electrolyte, pH, and ketone monitoring; add dextrose below 250 mg/dL so insulin can continue until ketonemia and acidosis resolve.
Correct sequence Stabilize and monitor → fluids and labs → replace low potassium and hold insulin → insulin after K >3.5 → frequent monitoring and add dextrose below 250.
Why this is correct DKA causes total-body potassium depletion even when the initial serum value is normal or high. Insulin shifts potassium intracellularly; starting it at 3.1 mmol/L can worsen hypokalemia and trigger arrhythmia or respiratory weakness. Dextrose is later added so insulin can continue clearing ketones after glucose improves.
NCLEX decision rule Do not start insulin in DKA with potassium below 3.5 mmol/L under the 2024 consensus. Fluids, potassium safety, insulin, and repeated reassessment are linked steps, not independent checkboxes.

Adult DKA protocolThe client is dehydrated with glucose 420 mg/dL, beta-hydroxybutyrate 5.2 mmol/L, bicarbonate 12 mmol/L, and venous pH 7.22. All protocol orders are available. Laboratory collection must not delay initial fluid resuscitation.
Total-Body Potassium Depletion — A net potassium deficit that can exist in DKA even when serum potassium is initially normal or elevated.
Ketonemia — An abnormally high concentration of ketone bodies in blood, preferably followed with beta-hydroxybutyrate in DKA.
Dextrose-Containing Fluid — IV fluid with glucose added during DKA treatment so insulin can continue clearing ketones after plasma glucose falls.
