Interventions for anxiety in the critically ill: a guide for nurses and families. 
Anxiety is a common feeling for patients and families during the critical care experience.  As anxiety for critically ill patients presents increased risks for morbidity and mortality, it is imperative that nurses strive to identify unrelieved anxiety early to prevent adverse events.  Alleviating anxiety experienced by families as a result of the critical care experience involves providing assurance, allowing them to remain near the patient, providing accurate and current information, providing for their comfort, and projecting a supportive attitude.  As constant care providers, nurses can have the greatest impact on creating an environment that is safe, healing, and humane for critically ill patients and their families.
