Final answer:
The nurse likely used program evaluation findings and national survey results to make the decision to focus on the middle-aged client's stress.
Step-by-step explanation:
The nurse likely used several sources of information to make the clinical decision to focus the assessment questions on the middle-aged client's amount of stress.
One source of information is the findings from a program evaluation that showed an increase in stress for clients between months three and six (Pruitt & Barile, 2017; Smith & Barile, 2015).
Another source of information is the results of national surveys that demonstrated higher stress levels in certain demographic groups, including men, Hispanic people aged 45-64, college graduates, and those with full-time employment (Cohen & Janicki-Deverts, 2012).
