The response to shock includes which of the following metabolic effects?
**Core Concept**
The body's response to shock involves a complex interplay of physiological and metabolic changes aimed at maintaining homeostasis and ensuring survival. In shock, the body's priority shifts from energy production to energy conservation, leading to a series of metabolic adaptations.
**Why the Correct Answer is Right**
The correct answer is related to the concept of gluconeogenesis, a metabolic pathway that generates glucose from non-carbohydrate sources such as amino acids, lactate, and glycerol. In shock, the body increases gluconeogenesis to maintain blood glucose levels, ensuring that vital organs, particularly the brain, receive a continuous supply of energy. This is mediated by the release of stress hormones like cortisol, adrenaline, and glucagon, which stimulate the production of glucose through gluconeogenesis.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe a metabolic effect of shock. While hypoglycemia may occur in severe cases of shock, it is not a direct response to shock.
* **Option B:** This option is incorrect because it is not directly related to the metabolic response to shock. While the body may experience a decrease in insulin sensitivity in shock, it is not a primary metabolic effect.
* **Option C:** This option is incorrect because it is not a characteristic metabolic response to shock. In fact, the body may experience a decrease in fatty acid oxidation in shock, leading to an increase in glucose utilization.
**Clinical Pearl / High-Yield Fact**
In shock, the body's metabolic response is characterized by an increase in gluconeogenesis, which helps to maintain blood glucose levels and ensure energy delivery to vital organs. This adaptation is mediated by stress hormones and is a key aspect of the body's response to shock.
**Correct Answer:** C. Gluconeogenesis
