Assess airway, breathing, circulation, mental status, vital signs, and cardiac rhythm Review potassium promptly; begin prescribed potassium replacement and defer insulin while potassium remains below 3.5 mmol/L Monitor glucose every 1 to 2 hours and electrolytes, venous pH, and ketones about every 4 hours; add dextrose when glucose falls below 250 mg/dL while insulin continues until ketoacidosis resolves Establish IV access, draw prescribed studies without delaying care, and begin the ordered isotonic crystalloid replacement Start the prescribed IV short-acting insulin infusion after potassium has increased above 3.5 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. ## In-depth explanation 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.Reference 12024 international consensus report on hyperglycemic crisesADA, EASD, JBDS, AACE, and DTS ## Clinical scenario Adult DKA protocol The 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. ## Key concepts - **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. ## Related questions - [Drag each assessment cluster to the most likely complication of peripheral IV therapy.](https://mymerci.kr/pages/nclex_q.php?qn_id=395447&lang=en) - [Place the nursing actions in order when an antineoplastic vesicant is suspected of extrava…](https://mymerci.kr/pages/nclex_q.php?qn_id=396413&lang=en) - [During a peripheral IV infusion of doxorubicin, a client reports burning at the site.
