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).
the most life-threatening consequence of hyperkalemia is arrhythmia and/or cardiac arrest, due to depolarization of the resting potential of cardiac myocytes. KCl injection is used as a form of capital punishment; it kills by stopping the heart (it is the last of the 3 drugs to be administered)
