What does data integrity refer to in nursing informatics?

  1. Data availability and accessibility

  2. How complete and correct data is

  3. The speed of data processing

  4. The security of the data

The correct answer is: How complete and correct data is

Data integrity in nursing informatics refers to how complete and correct the data is. This means that the data has not been altered or tampered with, ensuring its accuracy and reliability for making informed healthcare decisions. Options A, C, and D are not correct because data integrity specifically focuses on the accuracy and completeness of the data, rather than availability, speed of processing, or security.
