Stage 5 — Take action. Arrange the major DKA protocol decision points from initial treatment through transition. Assigned monitoring, laboratory, and precipitant-evaluation tasks continue in parallel.

Explanation
Protocol decision sequence Begin isotonic fluid → verify potassium safety → start IV insulin → add dextrose below 250 mg/dL while insulin continues → transition after ketone and acidosis resolution with insulin overlap. Monitoring and precipitant treatment occur throughout rather than waiting between steps.
Step 1 — Restore perfusion Initial isotonic saline or balanced crystalloid treats volume depletion and supports circulation. Rates are individualized rather than fixed without regard to cardiac, renal, and hemodynamic findings.
Step 2 — Use potassium as the insulin safety gate Verify potassium before insulin. Below 3.5 mmol/L, replace potassium first; above that threshold, begin prescribed IV insulin with serial monitoring.
Step 3 — Prevent hypoglycemia without stopping ketoacidosis treatment Add 5 to 10 percent dextrose when glucose falls below 250 mg/dL and continue insulin until beta-hydroxybutyrate and acidosis meet resolution criteria.
Step 4 — Prevent rebound When DKA has resolved and intake is feasible, administer the planned basal-bolus regimen before stopping IV insulin. The overlap prevents a gap in insulin action, rebound hyperglycemia, and recurrent ketoacidosis—not anaphylaxis.
NCLEX rule Sequence decision gates while recognizing continuous parallel monitoring.
Scenario (Stage 5 — Take action)Arrange the treatment decision points from volume restoration to safe IV-to-subcutaneous insulin transition.
Clinical judgment targetUse potassium, glucose, ketone, and acidosis thresholds without serializing the entire team response.
Insulin-action overlap — Giving basal subcutaneous insulin before the IV infusion ends to prevent a gap in insulin effect and recurrent hyperglycemia or ketoacidosis.
Resolution criteria — Beta-hydroxybutyrate below 0.6 mmol/L plus venous pH at least 7.3 or bicarbonate at least 18 mmol/L; glucose is ideally below 200 mg/dL.
Decision point — A clinical threshold that changes the next protocol action while other assessment and treatment tasks continue.
