1. The blood glucose does not normally elevate to 180 mg/dL, even after a large meal.
2. During a critical illness, pro-inflammatory factors cause insulin resistance, which also leads to hyperglycemia.
3. Beta blockers do mask the signs of hypoglycemia, but neither beta blockers nor nitroglycerin cause hyperglycemia.
4. A critical illness such as a myocardial infarction causes a physiologic stress response that causes the body to enter a hypermetabolic state in an attempt to heal.
5. In a critical illness, the reaction to counterregulatory hormones such as epinephrine, cortisol, and glucagon has a direct hormonal effect to produce hyperglycemia.
