Figure 2. The carbon-carbon double bond found in monounsaturated or polyunsaturated fatty acids can exist in the cis or trans configuration. When the two hydrogen atoms are on opposite sides of the double bond, the configuration is called trans.
Hyperkalemia is a medical emergency, yet the administration of insulin, in most circumstances, can wait until a pharmacy prepares a stat dose. In general, pharmacy should also prepare all insulin infusions using a standard concentration (e.g., 1 unit/mL).
Hypertonicity caused by hyperglycemia from glucose infusions can drive potassium out of the intracellular space, leading to hyperkalemia. Hyperkalemia may occur with continuous infusions or with boluses of hypertonic glucose. May be present with hypertonicity caused by other agents such as mannitol (Osmitrol) as well.
