A master's student who works in cardiothoracic ICU reads a 20-year-old nursing research study;
 
  the findings document use of much larger per-kilogram amounts of opioids and anxiolytics postoperatively in adults with open-heart surgery, as opposed to children with open-heart surgery. The student strongly suspects that modern hospitals medicate children and adults more or less the same, on a per-kilogram basis. She decides to replicate the original research in her hospital. What type of replication is this?
  a. Exact replication
  b. Concurrent replication
  c. Systematic replication
  d. Approximate replication

Question 2

A nurse researcher working in a subacute orthopedic hospital floor.
 
  She notes that her elders with knee replacements sleep as many as 16 hours a day, waking only for physical therapy and meals, but she also notices that those with many visitors sleep fewer hours and seem to experience more pain. She wonders whether sleep in elders after knee replacement prevents pain, or whether elders select the coping strategy of sleeping more, in response to pain, and begins to attempt to identify the relationship between the two. A literature search reveals only three descriptive studies on this topic, one quantitative and two qualitative. What is the relationship between elders' hours of sleep following knee replacement and its relationship with report of pain?
  a. The research aim
  b. The research purpose
  c. The research problem
  d. The research topic

Answer to Question 1

ANS: D
Replication involves reproducing or repeating a study to determine whether similar findings will be obtained. Four different types of replication are important in generating sound scientific knowledge for nursing: (1) exact, (2) approximate, (3) concurrent, and (4) systematic extension. An exact, or identical, replication involves duplicating the initial researcher's study to confirm the original findings. All conditions of the original study must be maintained. An approximate, or operational, replication involves repeating the original study under similar conditions, following the methods as closely as possible. A concurrent, or internal, replication involves the collection of data for the original study and its simultaneous replication to provide a check of the reliability of the original study. A systematic extension or constructive replication is done under distinctly new conditions.

Answer to Question 2

ANS: C
Research topics are concepts, phenomena of interest, or broad problem areas that researchers can focus on to enhance evidence-based nursing. A research problem is an area of concern where there is a gap in the knowledge base needed for nursing practice. Research topics contain numerous potential research problems, and each problem provides the basis for developing many research purposes.
