Answer to Question 1

1
Rationale: Data cleansing or scrubbing is a procedure that uses software to improve the quality of data to ensure that it is accurate enough for use in data mining and warehousing. It uses technology to reconcile data inconsistencies that arise from different systems as well as duplicate entries in one system. These inconsistencies may include typographical errors, misspellings, and various abbreviations as well as address changes.

Answer to Question 2

3
Rationale: Personal Digital Assistants or PDAs are an increasingly popular choice for nurses and other health care professionals. You may find a PDA to be a big help in your work. PDAs are a convenient way to store and access health care information. They are small (fit in a pocket or small pouch), are inexpensive, and can be frequently updated (unlike traditional reference books).
However, classroom response systems (CRS) are increasingly being deployed to facilitate learning via the use of handheld transmitters.
