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).
Plus, hyperkalemia (too much potassium in the blood) can lead to cardiac arrhythmias. This is rare in healthy people, but is definitely possible in people with renal insufficiency, people taking certain medications (i.e. beta blockers), and in certain endocrine conditions.
