A patient has been taught how to cough and deep breathe.Which evaluation method is most appropriate?

A) Return demonstration.
B) Computer instruction.
C) Verbalization of steps.
D) Cloze test.

To demonstrate mastery of the skill,the patient should perform a return demonstration under the same conditions that will be experienced at home or in the place where the skill is to be performed.Computer instruction is a programmed instruction format in which computers store response patterns for learners and select further lessons on the basis of these patterns (programs can be individualized).Computer instruction is a teaching tool rather than an evaluation tool.Verbalization of steps can be an evaluation tool,but it is not as effective for evaluating a psychomotor skill as a return demonstration is.In the Cloze test,a test of reading comprehension,patients fill in the blanks in a written paragraph.
