A nurse is assessing a child who has failure to thrive. Which of the following findings should the nurse expect?

A. Slow heart rate: Failure to thrive (FTT) typically does not cause a slow heart rate. In fact, a child who is significantly underweight and malnourished due to failure to thrive might have a normal or even slightly elevated heart rate as their body tries to compensate for inadequate energy intake. B. Low body weight: A hallmark of FTT is inadequate weight gain or significant weight loss, which manifests most commonly as a significantly low body weight for age, or a weight that falls below the 3rd or 5th percentile on growth charts, or a deceleration in growth velocity. C. Hyperactive behavior: FTT is often associated with lethargy or decreased activity rather than hyperactivity due to their poor nutritional status and lack of energy. Hyperactivity is more commonly associated with other conditions such as ADHD. D. Repetitive movements: Repetitive movements are not characteristic findings of FTT and may suggest other developmental or neurological issues. Failure to thrive is primarily a growth and nutritional disorder, and while it can coexist with other conditions, repetitive movements are not a core symptom.
