Answer to Question 1
2
Rationale 1: Whereas many studies have been done on cell division and growth, this option does not specifically indicate that the researcher is repeating another researcher's study.
Rationale 2: This is the best answer because the study is specifically designed to repeat the study done by another researcher. Replication studies are useful in validating findings.
Rationale 3: This is a new drug, so this is a new study, not a replication study.
Rationale 4: This is a new treatment, so this is a new study, not a replication study.
Answer to Question 2
2,3
Rationale 1: The cost of research varies from study to study and there is no indication that outcomes research is more expensive than other forms.
Rationale 2: Outcomes research has been put into a different category than qualitative and quantitative research specifically because the study design and methods may be somewhat different than traditional research.
Rationale 3: The increased interest in this type of study is linked to the high cost of health care.
Rationale 4: Outcomes research is placed into a separate category from traditional research because studies may include wide ranges of patients with varying levels of health, rather than focusing on a homogeneous sample group.
Rationale 5: Outcomes research focuses on measurable outcomes of interventions with certain patient populations, rather than on the efficacy of an individual nursing intervention in an individual patient.
