A patient with mild skin pigmentation comes to you because of sudden abdominal pain, fever and a rigid abdomen. Her lab repo show blood sugar of 55, Na 119, and K 6.2. Her BP 88/58. She undergoes exploratory laparotomy. Which statement is true?
**Core Concept**
The patient's presentation is suggestive of a hyperglycemic hyperosmolar state (HHS) complicated by severe abdominal pain, which may indicate an abdominal catastrophe. The patient's lab results show hyperglycemia, hyponatremia, and hyperkalemia, indicating severe dehydration and electrolyte imbalance. The patient's BP is low, indicating hypotension.
**Why the Correct Answer is Right**
The patient's abdominal pain and rigid abdomen suggest a surgical abdomen, which may be secondary to a complication of HHS such as pancreatitis or a pancreatic pseudocyst. The patient's lab results and clinical presentation are also consistent with diabetic ketoacidosis (DKA), which is often seen in patients with diabetes mellitus. However, the presence of hyperglycemia, hyponatremia, and hyperkalemia suggests HHS, which is often seen in patients with type 2 diabetes mellitus. The patient's hypotension may be due to severe dehydration and electrolyte imbalance.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because HHS is a complication of diabetes mellitus, and the patient's lab results and clinical presentation are consistent with HHS, not HHS secondary to another condition.
**Option B:** This option is incorrect because the patient's lab results and clinical presentation are consistent with HHS and DKA, not HHS secondary to pancreatitis.
**Option C:** This option is incorrect because the patient's lab results and clinical presentation are consistent with HHS and DKA, not HHS secondary to a pancreatic pseudocyst.
**Option D:** This option is incorrect because the patient's lab results and clinical presentation are consistent with HHS and DKA, not HHS secondary to another condition.
**Clinical Pearl / High-Yield Fact**
In patients with diabetes mellitus, HHS and DKA are often seen together, and the presence of one should prompt the clinician to look for the other. The patient's lab results and clinical presentation should be carefully evaluated to determine the underlying cause of the patient's symptoms.
**Correct Answer:** C.
