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).
Hyperkalemia is abnormally high potassium levels in the extracellular (i.e. outside) fluid. This is in contrast to hypokalemia, which is an abnormally low level of potassium. To remember the difference between the prefixes hyper- and hypo-, visualize a hyper child that has had too much sugar.
