A clinic nurse is assessing an 8-year-old child with obesity for potential metabolic complications. Which finding would be most indicative of such complications?
1Body mass index (BMI) at the 85th percentile for age and gender
2Presence of stretch marks on the abdomen and thighs
3Blood pressure reading of 125/80 mmHg✓ 정답
4Complaints of joint pain in the knees during physical activity
해설
Elevated blood pressure (125/80 mmHg) in a child is a key indicator of metabolic complications from obesity, such as hypertension and cardiovascular risk. Other options represent non-metabolic findings.
Clinical Judgment
This question assesses clinical judgment in identifying metabolic complications of pediatric obesity. The key lies in the word 'metabolic.' Rather than obesity itself, you need to find findings that indicate internal metabolic abnormalities (blood pressure, blood sugar, lipids, etc.) caused by obesity.
Memory Tip:
Blood Pressure is a Big deal! When remembering metabolic complications of pediatric obesity, blood pressure is the most common and important early signal. Other symptoms (joint pain, skin changes) mainly reflect mechanical problems.
KR vs US:
In Korea, screening for pediatric hypertension may be relatively less emphasized, but in the US NGN, blood pressure measurement is an essential standard procedure when evaluating pediatric obesity. A reading of 125/80 mmHg in a 10-year-old child corresponds to a significantly high value when calculated by age percentile, requiring immediate evaluation and intervention.
Clinical Practice GuideWhen assessing a child suspected of obesity, the school nurse must measure blood pressure in addition to height and weight (BMI calculation). Pediatric hypertension is often asymptomatic, making screening essential.
Caution:A common pitfall in SATA (Select All That Apply) questions is asking to choose "all findings related to obesity." If the question specifies "metabolic complications," mechanical complications (joint pain) or cosmetic changes (stretch marks) should be excluded.
Childhood Obesity — Childhood obesity. A condition in children and adolescents aged 2–19 years where the body mass index (BMI) for age and sex is at or above the 95th percentile.
Metabolic Syndrome — Metabolic syndrome. A condition where abdominal obesity, high blood pressure, high blood sugar, and dyslipidemia (high triglycerides, low HDL cholesterol) combine to significantly increase the risk of cardiovascular disease and type 2 diabetes.
Hypertension (in Pediatrics) — Pediatric hypertension. Defined based on blood pressure percentiles according to age, sex, and height. Below the 95th percentile is normal, 90th to 95th percentile is prehypertension, and above the 95th percentile is classified as hypertension.
Body Mass Index (BMI) Percentile — Body mass index percentile. A percentile that compares a child or adolescent's BMI to other children of the same age and sex. Unlike the absolute BMI values used for adults, this is a relative indicator that reflects growth curves.
Insulin Resistance — Insulin resistance. A condition in which the body's cells do not respond properly to the insulin hormone, preventing effective utilization of blood sugar. It is a major metabolic consequence of obesity, especially abdominal obesity, and a precursor stage to type 2 diabetes and cardiovascular disease.
