In the context of a 5-month-old with decreased oral intake and weakness, what would be an expected finding on examination?

In a 5-month-old infant with decreased oral intake and weakness, the expected finding of absent deep tendon reflexes suggests a potential underlying neurological issue that may be contributing to the infant's overall weakness. In cases of weakness, decreased reflexes can indicate lower motor neuron involvement or an overall significant decrease in muscle strength and tone, which may arise from various conditions such as neuromuscular disorders or metabolic disturbances.

When an infant has reduced oral intake, it can lead to overall poor nutrition and muscle weakness. This lack of nutrition could potentially affect the nervous system and muscle function, leading to diminished reflexes.

Other choices, such as increased appetite, would contradict the symptoms of decreased oral intake. Strong muscle tone is unlikely in a scenario where weakness is present, as strong muscle tone typically suggests normal neurological function and muscle strength. Severe distension may indicate gastrointestinal issues but would not be a direct finding related to the decreased oral intake and resultant weakness, making absent deep tendon reflexes a more relevant examination finding in this context.
