Zorluk: OrtaPhysiological Adaptation

An adolescent client is brought to the emergency department exhibiting deep, rapid respirations, a fruity breath odor, and severe lethargy. The initial capillary blood glucose is 580 mg/dL580 \text{ mg/dL} (32.2 mmol/L32.2 \text{ mmol/L}). The healthcare provider diagnoses diabetic ketoacidosis (DKA). Arrange the following nursing actions in the priority order they should be performed.

  1. 1Assess airway patency and apply supplemental oxygen.
  2. 2Establish large-bore intravenous access.
  3. 3Administer a rapid intravenous infusion of 0.9%0.9\% sodium chloride.
  4. 4Initiate a continuous intravenous infusion of regular insulin.
  5. 5Monitor serum potassium levels closely and replace as prescribed.

Cevap

The correct sequence prioritizes immediate life support followed by specific DKA management: first, assess airway patency and apply oxygen; second, establish large-bore IV access; third, administer a rapid IV infusion of 0.9%0.9\% sodium chloride; fourth, initiate a continuous IV infusion of regular insulin; and finally, monitor serum potassium levels and replace as prescribed.
The correct sequence follows the ABCs (Airway, Breathing, Circulation) of emergency resuscitation combined with the standard protocol for Diabetic Ketoacidosis (DKA). Airway protection and oxygenation are always the first priority for a lethargic client. Once the airway is secured, IV access must be established to provide a route for rapid emergency interventions. The immediate medical priority in DKA is aggressive fluid resuscitation with isotonic saline to reverse severe dehydration and prevent hypovolemic shock. Only after fluid resuscitation has begun should continuous IV regular insulin be initiated to correct the hyperglycemia and acidosis. Finally, because insulin drives potassium into the intracellular space, continuous monitoring and subsequent replacement of potassium are essential to prevent life-threatening dysrhythmias.

Adım Adım Çözüm

1
Apply the ABCs (Airway, Breathing, Circulation) framework to prioritize immediate life-saving actions.
Assessing airway patency and applying oxygen is identified as the absolute first action.
Airway and oxygenation always take precedence in an emergency, especially in a patient with a compromised neurological status and altered respiratory patterns (Kussmaul respirations).
2
Identify the next most critical requirement for treating a client in severe metabolic distress.
Establishing large-bore IV access is prioritized next.
Without reliable intravenous access, life-saving fluids and medications cannot be administered to the client.
3
Determine the initial circulatory intervention for DKA.
Administering a rapid infusion of 0.9%0.9\% sodium chloride is the third action.
Severe dehydration and hypovolemia from osmotic diuresis must be corrected first to restore tissue perfusion and prevent vascular collapse.
4
Sequence the treatment for the underlying metabolic acidosis and hyperglycemia.
Initiating a continuous IV infusion of regular insulin is the fourth action.
Insulin halts ketone production and drives glucose into the cells, directly treating the pathophysiology of DKA, but it must only be given after fluid resuscitation has started.
5
Anticipate the complications of the medical interventions.
Monitoring and replacing potassium is the final action in this immediate sequence.
Intravenous insulin therapy drives potassium into the intracellular space, causing hypokalemia. This requires continuous monitoring and replacement once adequate urine output is confirmed.
