Which of the following statements is a problem statement?

A problem statement clearly identifies an issue that needs to be addressed and serves as a foundation for framing research questions. In this case, the statement about medication errors indicates a specific, measurable problem that is currently affecting healthcare—a significant rise in medication errors. This statement highlights a pressing concern that can be investigated further, making it a clear articulation of the problem at hand.

The other statements focus more on the intentions or objectives of research rather than identifying a specific problem. For example, mentioning the purpose of a study or suggesting areas for future research does not convey a particular issue that needs solving. Consequently, option B stands out as it emphasizes a real and measurable problem in need of further investigation.
