Orthopaedic Nurse Test Research & Evidence-Based Practice 4

Question 1

A nurse is implementing EBP for post-operative orthopaedic pain management. Which Iowa Model step follows the identification of a clinical problem?

Accepted Answer

Form a team and review the literature

Answer

After identifying a clinical problem in the Iowa Model, the next step is to assemble a team and conduct a thorough literature review.

Question 2

An orthopaedic researcher uses stratified randomization to ensure equal distribution of age groups between study arms. The primary purpose is to:

Accepted Answer

Reduce selection bias and confounding

Answer

Stratified randomization ensures that important variables like age are evenly distributed across groups, reducing confounding.

Question 3

In an orthopaedic cohort study, participants who had knee replacement surgery are followed for 2 years for complications. The exposure in this study is:

Accepted Answer

Knee replacement surgery

Answer

In a cohort study, the exposure is the factor under investigation—in this case, knee replacement surgery.

Question 4

A nurse reviews an article where participants were not told whether they received real or sham ultrasound therapy for bone healing. This describes which type of blinding?

Accepted Answer

Single-blind

Answer

Single-blind means only the participants are unaware of their group assignment, while researchers know the allocation.

Question 5

Which outcome measure would be most appropriate for an EBP project focused on patient-centered outcomes after total hip arthroplasty?

Accepted Answer

Patient-reported outcome measure (PROM) such as the Harris Hip Score

Answer

PROMs like the Harris Hip Score capture the patient's own assessment of function and pain, making them ideal for patient-centered outcomes.
