Intervention is not the key element that the nurse should include in this evidence-based research
question, because it is already included. The intervention is the use of guided imagery with oral analgesics.
 

Population is not the key element that the nurse should include in this evidence-based research question, because it is already included. The population is implied by the context of pain relief, which suggests that the participants are patients who experience pain.
 

Outcome is not the key element that the nurse should include in this evidence-based research question, because it is already included. The outcome is pain relief.

Comparison is the key element that the nurse should include in this evidence-based research question. A comparison is the alternative or control condition that is used to contrast with the intervention or treatment of interest. A comparison can be another intervention or treatment, a placebo, a standard of care, or no intervention at all. A comparison helps to evaluate the relative effectiveness or superiority of the intervention or treatment of interest. A comparison is one of the components of a well-formulated

evidence-based research question, which can be structured using the PICO framework. PICO stands for Population, Intervention, Comparison, and Outcome. A PICO question specifies the population or participants of interest, the intervention or treatment of interest, the comparison or alternative condition, and the outcome or result of interest. A PICO question helps to focus and refine the research question, as well as to guide the search and selection of relevant evidence . In this case, the nurse should include a comparison in the evidence-based research question to compare the use of guided imagery with oral analgesics versus another condition, such as oral analgesics alone or placebo.
