Experienced and Less-Experienced Nurses Diagnostic Reasoning: Implications for Fostering Students' Critical Thinking

PURPOSE. To compare the use of mental representations (heuristics) in diagnostic reasoning of expert (≥5 years' experience) and novice (<5 years' experience) emergency nurses.
METHODS. Clinical simulations were completed by a nationwide randomly selected sample of 173 experienced and 46 less-experienced emergency nurses ( N = 229).
FINDINGS. Experienced nurses used the heuristic, Judging by Causal Systems (diagnostic inferences deduced from systems of causal factors) significantly more did than less-experienced nurses.
PRACTICE IMPLICATIONS. Standardized nursing diagnoses may cut short the time needed to develop representational thinking and spare cognitive reserves for reasoning needed for complex patients. Faculty need to promote students' cognitive development through strategies that promote active, reflective, and integrative learning.
