In this section, the variables of interest to the literature
review are defined at the conceptual level. These
definitions guided the specification of criteria for
selecting the studies and facilitated data extraction.
Nursing Assessment is the first phase of the nursing
process to collect data about health status and state
to monitor for the evidence of health problems and
risk factors that may cause health problems (AlfaroLeFevre,
2002).
Nursing Diagnosis is the analyzing phase of health
data and information collected to identify potential
or actual health problem and health promotion and
strengths, priority areas of practitioner and client
health-related concerns (Alfaro-LeFevre, 2002;Martin,
2005).
Nursing Intervention are professional actions or
activities implemented by a nurse to address a specific
client problem and to improve, maintain, or restore
health or prevent illness (Martin, 2005; Martin &
Scheet, 1992).
Nursing Outcome refers to the measurements
over time of changes effected in nursing diagnosis as
a result of nursing interventions (Doran, 2003).
