A 12-year-old child with newly diagnosed type 1 diabetes mellitus is being assessed by the nurse. Which assessment finding would be the MOST concerning and require immediate intervention?
1Blood glucose level of 180 mg/dL (10.0 mmol/L)
2Presence of ketones in urine
3Complaints of increased thirst and frequent urination
4Kussmaul respirations with fruity breath odor✓ 정답
해설
Kussmaul respirations with fruity breath odor indicate diabetic ketoacidosis (DKA), a life-threatening emergency requiring immediate intervention. Other findings like hyperglycemia, ketonuria, or polyuria are concerning but less urgent.
Clinical Judgment
This question assesses clinical judgment in identifying the most dangerous emergency situation in a child with type 1 diabetes. The key point is that Kussmaul breathing and fruity breath are definitive signs of Notify HCP! diabetic ketoacidosis (DKA). DKA is a life-threatening metabolic acidosis state caused by insulin deficiency, requiring immediate treatment (intravenous fluids, insulin, electrolyte correction). The other options represent typical symptoms of diabetes or manageable conditions.
Memory Tip: To remember the danger signs of DKA, think of the acronym FKA: "Fruity breath, Kussmaul, Acidosis." When these three appear together, you must act immediately.
KR vs US: Both Korea and the US recognize DKA as a severe emergency, but the US NGN exam emphasizes the 'Recognizing' and 'Responding' steps of the Clinical Judgment Model (CJMM), especially in pediatric patients. It assesses the ability to prioritize which signs require the most immediate intervention, rather than simply listing symptoms.

Clinical Practice Guide
When evaluating pediatric patients with type 1 diabetes, you must be more sensitive to DKA signs than to classic symptoms like 'POLYDIPSIA' (polyuria, polydipsia). Immediately recognize Kussmaul respirations (deep, rapid breathing), fruity breath, abdominal pain, vomiting, and altered level of consciousness.
Caution: A common pitfall in SATA (Select All That Apply) questions is confusing 'symptoms of diabetes' with 'symptoms of DKA.' Hyperglycemia, ketonuria, and polydipsia/polyuria may be risk factors or early signs of DKA, but respiratory compensation mechanisms like Kussmaul respirations indicate already advanced metabolic acidosis. In questions asking for the "most concerning" finding, always select the sign that directly threatens life.
핵심 개념
Diabetic Ketoacidosis — Diabetic ketoacidosis. A life-threatening emergency condition in which severe insulin deficiency leads to hyperglycemia, ketone body production, and metabolic acidosis.
Kussmaul Respirations — Kussmaul breathing. A deep, rapid, and labored breathing pattern, which is a compensatory mechanism where the body tries to eliminate excessive carbon dioxide to correct metabolic acidosis (e.g., DKA).
Type 1 Diabetes Mellitus — Type 1 diabetes. Diabetes caused by the absolute deficiency of insulin due to autoimmune destruction of pancreatic beta cells. It mainly occurs in childhood and adolescence.
Ketones / Ketonuria — Ketone bodies / Ketonuria. Acidic substances produced when fat is broken down as an energy source due to insulin deficiency. Detection in urine (ketonuria) indicates insufficient insulin action.
Fruity Breath Odor — Fruity breath. A characteristic odor that occurs when acetone, one of the ketone bodies, is excreted through exhaled gas. It is a major clinical sign of DKA.
