Answer to Question 1
Correct Answer: 2
Rationale 1: Validity is the degree to which an instrument measures what it is supposed to measure.
Rationale 2: Reliability is the degree of consistency with which an instrument measures a concept or variable. If it is reliable, repeated measurement of the same variable should yield similar or nearly similar results.
Rationale 3: Consistency is a component of reliability.
Rationale 4: Variability does not describe instrument measurement, but variances in data.
Answer to Question 2
Correct Answer: 2
Rationale 1: Presenting papers or explaining what EBP is to someone else does not demonstrate the ability to put into practice that which is learned.
Rationale 2: In evidence-based practice, the nurse integrates research findings with clinical experience, the client's preferences, and available resources in planning and implementing care. Evidence-based practice would support frequent repositioning to prevent skin breakdown in an at-risk client, demonstrating that this student is able to incorporate research into practice.
Rationale 3: Explaining what EBP is to someone else does not demonstrate the ability to put into practice that which is learned.
Rationale 4: Attempting to find other problems to implement EBP does not demonstrate the ability to put into practice that which is learned.
