10) ANSWER  B)Decrease score on depression scale by one half.

Explanation

Option 2 is correct. This option is measurable, and the others are not. Statements of client outcomes should be written in specific measurable terms so that any nurse could determine outcome achievement or lack of achievement. This option indicates that a specific numerical comparison can be made. Options 1, 3, and 4 are incorrect. Each of them indicates the nurse's intention to bring about a change in the client's status, but not one of them is measurable. How does one measure "more" or "increase" without a standard of comparison? Recall basic elements of a well-written outcome statement, including its measurability.
