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).
Excessive potassium intake alone is a very uncommon cause of hyperkalemia in anyone with an estimated GFR higher than 60 mL/min. The mechanisms for shifting potassium intracellularly and for renal excretion allow a person with normal potassium homeostatic mechanisms to ingest very high quantities of potassium.
