KEY TO ESSENTIAL TERMINOLOGY,Client Assessment Database. Provides an overview of the more commonly occurring etiology and coexisting factors associated with a specific medical. and or surgical diagnosis as well as the signs and symptoms and corresponding diagnostic findings. Nursing Priorities, Establishes a general ranking of needs and concerns on which the Nursing Diagnoses are ordered in constructing the plan of. care This ranking would be altered according to the individual client situation. Discharge Goals, Identifies generalized statements that could be developed into short term and intermediate goals to be achieved by the client. before being discharged from nursing care They may also provide guidance for creating long term goals for the client to. work on after discharge,Nursing Diagnosis, The general need or problem diagnosis is stated without the distinct cause and signs and symptoms which would be added. to create a client diagnostic statement when specific client information is available For example when a client displays. increased tension apprehension quivering voice and focus on self the nursing diagnosis of Anxiety might be stated severe. Anxiety related to unconscious conflict threat to self concept as evidenced by statements of increased tension apprehension. observations of quivering voice focus on self, In addition diagnoses identified within these guides for planning care as actual or risk can be changed or deleted and. new diagnoses added depending entirely on the specific client information. May Be Related to Possibly Evidenced by, These lists provide the usual or common reasons etiology why a particular need or problem may occur with probable signs. and symptoms which would be used to create the related to and evidenced by portions of the client diagnostic statement. when the specific situation is known, When a risk diagnosis has been identified signs and symptoms have not yet developed and therefore are not included in. the nursing diagnosis statement However interventions are provided to prevent progression to an actual problem The excep. tion to this occurs in the nursing diagnosis risk for Violence which has possible indicators that reflect the client s risk status. Desired Outcomes Evaluation Criteria Client Will, These give direction to client care as they identify what the client or nurse hopes to achieve They are stated in general terms. to permit the practitioner to modify or individualize them by adding time lines and specific client criteria so they become. measurable For example Client will appear relaxed and report anxiety is reduced to a manageable level within 24 hours. Nursing Outcomes Classification NOC labels are also included The outcome label is selected from a standardized. nursing language and serves as a general header for the outcome indicators that follow. Actions Interventions, Nursing Interventions Classification NIC labels are drawn from a standardized nursing language and serve as a general. header for the nursing actions that follow, Nursing actions are divided into independent those actions that the nurse performs autonomously and collaborative. those actions that the nurse performs in conjunction with others such as implementing physician orders The interventions in. this book are generally ranked from most to least common When creating the individual plan of care interventions would nor. mally be ranked to reflect the client s specific needs and situation In addition the division of independent and collaborative is. arbitrary and is actually dependent on the individual nurse s capabilities and hospital and community standards. Although not commonly appearing in client plans of care rationale has been included here to provide a pathophysiological. basis to assist the nurse in deciding about the relevance of a specific intervention for an individual client situation. Clinical Pathway, This abbreviated plan of care or care map is event or task oriented and provides outcome based guidelines for goal achieve. ment within a designated length of stay Several samples have been included to demonstrate alternative planning formats.
