A 74-year-old client with type 2 diabetes and stage 3 chronic kidney disease has HHS with BP 92/54 mm Hg, glucose 824 mg/dL, effective osmolality 326 mOsm/kg, potassium 3.4 mmol/L, drowsiness, and acute kidney injury. Place the treatment actions in the safest sequence.

Choose your responses, then check the answer.
Explanation
The sequence restores perfusion, corrects potassium below 3.5 mmol/L before insulin, begins insulin safely, adds dextrose while hyperosmolality continues to resolve, and transitions only after HHS resolution criteria and insulin overlap are met.
Why this is correct Fluids address hypovolemia first. Because potassium is 3.4 mmol/L, replacement and monitoring precede insulin. Dextrose is added as glucose falls so insulin can continue while osmolality and cognition recover; transition follows resolution and overlap planning.
Easy analogy or mental picture Treat HHS like restoring a concentrated circulation system: refill carefully, protect potassium, then lower glucose and osmolality at a controlled rate.
NCLEX decision rule Use the client's current potassium and perfusion to order the first steps, then require objective HHS resolution before transition.
Why the other choices are wrong Starting insulin before potassium correction risks arrhythmia, and stopping treatment when glucose alone improves can leave hyperosmolality unresolved.
