What is one possible consequence of a newborn suffering from cold stress?

• A. Increased weight gain
• B. Improved muscle tone
• C. Severe jaundice
• D. Hypoglycemia

Answer: (D)

Hypoglycemia, or low blood sugar, is a significant consequence when a newborn experiences cold stress. Cold stress can lead to an increased metabolic rate as the body attempts to generate heat to maintain its core temperature. This heightened metabolic demand requires energy, which in newborns typically comes from glucose. As the body utilizes its glucose stores to compensate for the heat loss, it can result in decreased blood sugar levels, leading to hypoglycemia.

In contrast, increased weight gain and improved muscle tone are generally associated with healthy metabolic processes and not a result of cold stress. Severe jaundice, while a serious condition that can occur in newborns, is not a direct effect of cold stress. Instead, it involves the accumulation of bilirubin, which is unrelated to the mechanisms of heat regulation and metabolic demand triggered by cold exposure. Therefore, the connection between cold stress and hypoglycemia highlights the body's need to regulate temperature and energy, making hypoglycemia a relevant and concerning consequence of cold stress.
