Question 45 / 5 ptsA nurse researcher works on a subacute orthopedic hospital floor. She notes that elders with knee replacements sleep as many as 16 hours a day, waking only for physical therapy and meal. 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. She wants to identify the possible relationship between sleep and pain so she conducts a literature search which reveals only three descriptive studieson 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”?The research questionThe research problemThe research purposeResearch topics are concepts, phenomena of interest, or broad problem areas that researchers can focus on to enhance evidence-based nursing.
