Zorluk: Çok zorReduction of Risk Potential

A client who was admitted for diabetic ketoacidosis (DKA) now has a closed anion gap and a blood glucose of 180 mg/dL180 \text{ mg/dL} (10.0 mmol/L10.0 \text{ mmol/L}). The healthcare provider prescribes transitioning the client from the continuous intravenous regular insulin infusion to a subcutaneous insulin regimen. To reduce the risk of physiological decompensation, in what order should the nurse perform the following actions? Arrange the actions from first to last.

  1. 1Confirm the client's nausea has resolved and the scheduled meal is at the bedside.
  2. 2Administer the prescribed subcutaneous dose of rapid-acting and long-acting insulin.
  3. 3Assist the client in consuming the meal immediately after the injection.
  4. 4Maintain the continuous intravenous regular insulin infusion for 11 to 22 hours.
  5. 5Discontinue the intravenous regular insulin infusion and remove the intravenous tubing.

Cevap

The correct sequence is: Confirm the meal is at the bedside, administer the subcutaneous insulin, assist the client to eat, maintain the IV insulin for 1 to 2 hours, and finally discontinue the IV insulin.
When transitioning a client with resolved diabetic ketoacidosis (DKA) from intravenous (IV) to subcutaneous (SQ) insulin, the primary risk reduction goal is preventing a relapse of DKA while avoiding hypoglycemia. Because IV regular insulin has a half-life of only minutes, stopping it abruptly causes immediate insulin deficiency. The nurse must first ensure food is present, give the SQ insulin, have the client eat, and then crucially maintain the IV infusion for an overlap period of 11 to 22 hours. This allows the SQ insulin to reach a therapeutic level before the IV supply is removed.

Adım Adım Çözüm

1
Assess the client's readiness to eat and ensure the meal is physically present at the bedside.
Hypoglycemia risk is mitigated before administering rapid-acting insulin.
Subcutaneous rapid-acting insulin has an onset of 1010 to 1515 minutes. Administering it without guaranteed immediate oral intake risks severe hypoglycemia.
2
Administer the prescribed subcutaneous dose of insulin.
The subcutaneous insulin depot is created.
This initiates the transition process, but the subcutaneous insulin will take time to absorb and reach therapeutic blood levels.
3
Instruct the client to consume the meal.
Carbohydrate absorption matches the onset of the rapid-acting insulin.
Provides glucose to prevent hypoglycemia as the insulin begins to peak.
4
Maintain the continuous intravenous regular insulin infusion for 11 to 22 hours.
Continuous insulin coverage is maintained during the subcutaneous absorption phase.
Intravenous regular insulin has a half-life of only minutes. An overlap period is required to prevent a critical gap in insulin coverage, which would cause rapid rebound hyperglycemia and potentially reopen the anion gap.
5
Discontinue the intravenous regular insulin infusion.
The transition to subcutaneous insulin is safely completed.
The subcutaneous insulin has now reached a therapeutic level, making the intravenous infusion unnecessary and preventing late hypoglycemia.
