A Researcher Studies the Effect of a Computerized Hospital Charting

question 11

Multiple Choice

A researcher studies the effect of a computerized hospital charting system on nurses' compliance with charting the exact times of tracheostomy care, periodic turning of patients, and bed baths. The researcher hypothesizes that instituting the new charting system would improve compliance. The sample size is 120. The level of significance is set at 0.05 and the power at 80%. Findings are nonsignificant, at p = 0.146. How might this be discussed by the researcher?

• A)The null hypothesis was accepted. There was no difference in compliance when paper charting was replaced with computer charting, in terms of the variables of tracheostomy care, periodic turning, and bed bath charting.b.Nurses do not chart consistently the tracheostomy care, periodic turning, and bed baths they deliver, regardless of charting system.
• C)The effect size was smaller than expected; a repeat power analysis revealed that the sample size of 120 was insufficient to demonstrate a significant difference.
• D)This study showed no significant difference between the two charting methods, in terms of compliance.
• E)Had the level of significance been set at 0.15, the findings would have reached statistical significance.
