The number of IV site infections has more than doubled on a nursing unit. The staff determine common causes include the site is cleaned using inconsistent methods, dressing frequently becomes wet when patient showers, IV tubing is not changed every 48 hours per protocol, and inadequate hand washing of RN prior to insertion. A bar graph demonstrates the frequency in descending order, with 80% of infections being attributed to inadequate hand washing. The quality tool used is a:
Correct Answer: C
Rationale: The correct answer is C: Pareto chart. A Pareto chart is a quality tool used to prioritize issues by identifying the most significant factors contributing to a problem. In this case, the Pareto chart is appropriate because it helps visually show that inadequate hand washing is the primary cause of IV site infections, as it accounts for 80% of all infections. The chart allows the staff to focus their efforts on addressing this key issue first, which is crucial for effectively reducing the overall infection rate.
Incorrect choices:
A: Cause-and-effect diagram - This tool is used to identify and analyze potential causes of a problem, but it does not prioritize them in the same way a Pareto chart does.
B: Run chart - A run chart is used to track data over time to identify trends and patterns, but it does not prioritize the causes of a problem like a Pareto chart.
D: Flowchart - Flowcharts are used to map out a process or workflow, but they do not prioritize issues
