A nurse is reviewing the technique used to identify the factors involved in an error. Which statement indicates the nurse has an adequate understanding?
a. "The rapid cycle test is a technique that is widely used.".
b. "A root cause analysis is a process de-signed to investigate and categorize the root cause of the event.".
c. "A failure mode and effects analysis is a procedure to investigate the cause of the error.".
d. "Define, measure, analyze, improve, con-trol prevents events from occurring.".
B
When an error is analyzed, the primary causes need to be determined so that a workable and ef-fective solution can be developed. A root cause analysis is such a process designed to investigate and categorize the root cause of the event. The Six Sigma DMAIC process (define, measure, analyze, improve, control) is used primarily for improving existing processes that do not meet institutional goals or national norms. Rapid cycle tests are components of continuous quality im-provement. A failure mode and effects analysis (FMEA) is a procedure in product development and operations management for analysis of potential failure modes within a system for classifica-tion by the severity and likelihood of the failures.

A nurse is explaining the need to obtain a CBC and culture on a client who has an infection and is of a cultural group different from the nurse's
During the interview, the client averts her eyes and refrains from answering questions for long periods of time. The nurse should: 1. Come back at a different time, when the client is feeling more communicative. 2. Have another nurse finish the interview, since there is something uncomfortable the client senses. 3. Understand that this may be completely appropriate and take cues accordingly. 4. Leave the room and come back after having learned more about this particular culture.
