Critically ill patients have multiple complex medical problems, necessitating interventions by the critical care team. Administer ingmedications is a nursing intervention that is provided to ICU patients. For example, fluid and electrolyte imbalance may be regulated by the administration of medications. It is not unusual for a critically patient to be receiving a continuous intravenous vaso pressor to increase blood pressure, an antibiotic, a corticosteroid, and an analgesic all at the same time (Roy, 2009). Medication administration is one of the most important roles of critical care nurses.
