Under the Health Data Analytics domain, NAHQ emphasizes the use of standardized, nationally recognized data sources for external benchmarking. The National Healthcare Safety Network (NHSN) is the primary surveillance system used for tracking healthcare-associated infections, including central line–associated bloodstream infections (CLABSIs).

NHSN provides risk-adjusted benchmarks, standardized definitions, and national comparison data, making it the most appropriate source for external benchmarking. NIH focuses on research, NQF endorses measures but does not collect performance data, and AHRQ provides tools and reports rather than infection surveillance data. Therefore, Option B is the correct and exam-aligned answer.
