Questions and Answers

Which of the following best describes the primary aim of clinical research?

  • To provide material for publications and career advancement of researchers.
  • To improve individual and public health through structured investigation of facts, theories, and connections. (correct)
  • To satisfy academic curiosity regarding specific clinical phenomena.
  • To generate revenue for healthcare institutions through innovative studies.

A physical therapist is treating a patient with a complex musculoskeletal injury. How can research best assist the therapist in making informed decisions about the patient's care?

  • By reinforcing traditional treatment approaches that have been used for many years.

  • By creating a standardized treatment protocol that can be applied to all patients with the same diagnosis.
  • By offering a systematic way to examine clinical conditions and outcomes, generating evidence for decision making. (correct)

What is the ultimate goal of research, according to Beck & Polit (2017)?

  • To secure funding for further research endeavors.
  • To challenge established theories and practices in healthcare.
  • To develop and expand the existing body of knowledge. (correct)
