**Core Concept**
Carcinoid crisis is a life-threatening condition that occurs in patients with carcinoid tumors, which are neuroendocrine tumors that produce excessive amounts of serotonin and other vasoactive substances. This excessive hormone production leads to a cascade of systemic effects, including vasodilation, bronchospasm, and cardiac dysfunction. The pathophysiology of carcinoid crisis involves the release of serotonin, which stimulates the release of histamine and other mediators, leading to a systemic inflammatory response.

**Why the Correct Answer is Right**
Carcinoid crisis is typically triggered by the rapid release of serotonin from a carcinoid tumor, often in response to anesthesia, surgery, or other stressors. The serotonin released stimulates the release of histamine and other mediators, leading to vasodilation, bronchospasm, and cardiac dysfunction. The clinical presentation of carcinoid crisis includes symptoms such as hypotension, tachycardia, bronchospasm, and diarrhea.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because carcinoid crisis is not typically associated with hyperglycemia. In fact, patients with carcinoid crisis may experience hypoglycemia due to the release of insulin-like peptides from the tumor.
**Option B:** This option is incorrect because carcinoid crisis is not typically associated with an increase in blood pressure. Instead, patients with carcinoid crisis often experience hypotension due to the release of vasodilatory substances.
**Option C:** This option is incorrect because carcinoid crisis is not typically associated with an increase in white blood cell count. In fact, patients with carcinoid crisis may experience a decrease in white blood cell count due to the release of cytokines and other inflammatory mediators.

**Clinical Pearl / High-Yield Fact**
The key to managing carcinoid crisis is to prevent the rapid release of serotonin from the tumor. This can be achieved through the use of somatostatin analogs, such as octreotide, which can help to reduce serotonin release and prevent the onset of carcinoid crisis.

**Correct Answer: B.**
