Quizplus · Accepted Answer

Nurse researchers can use eligibility criteria to restrict the study population to homogeneous groups of subjects. Eligibility criteria are predetermined characteristics that individuals must possess to be included in the study. By using eligibility criteria, nurse researchers can ensure that the study population is homogeneous in terms of relevant variables such as age, gender, diagnosis, and comorbidities. This helps to reduce the potential confounding effect of extraneous variables on the study results and increases the internal validity of the study. Eligibility criteria can also be used to exclude individuals with certain characteristics that may confound the study results or make it difficult to interpret them. Thus, using eligibility criteria is an essential step in ensuring that a nurse research study is well-designed and valid.
