A nurse is caring for a newborn diagnosed with erythema toxicum neonatorum. Which nursing action is most appropriate?
Explanation & Rationale
A. Triglyceride level of 160 mg/dL: A fasting serum triglyceride level ≥ 150 mg/dL is a recognized diagnostic criterion for metabolic syndrome. Hypertriglyceridemia reflects impaired lipid metabolism and is often associated with insulin resistance and increased cardiovascular risk. This value exceeds the threshold established by the NCEP ATP III guidelines. B. Waist circumference of 42 inches (male): Central adiposity is a key component of the syndrome, defined as a waist circumference > 40 inches in men. This measurement indicates an excess of visceral fat, which is metabolically active and promotes systemic inflammation. It is a more significant predictor of metabolic risk than total body mass. C. Blood pressure of 118/78 mmHg: This blood pressure reading falls within the normal physiological range and does not meet the diagnostic threshold. Metabolic syndrome requires a blood pressure ≥ 130/85 mmHg or the use of antihypertensive medication. Normal vascular pressure does not support a diagnosis of this metabolic cluster. D. Fasting blood glucose of 110 mg/dL: A fasting plasma glucose level ≥ 100 mg/dL is an indicator of impaired fasting glucose and insulin resistance. This elevation is one of the five core criteria used to identify individuals with metabolic syndrome. It suggests a pre-diabetic state that requires lifestyle or pharmacological intervention. E. HDL cholesterol of 55 mg/dL (female): In females, a high-density lipoprotein level < 50 mg/dL is considered a risk factor for metabolic syndrome. Since 55 mg/dL is above this cutoff, it represents a protective lipid profile rather than a pathological finding. This result does not contribute to the diagnosis of the syndrome.
