example question

Question 1

A kinesiology researcher, lacking a formal background in nutrition or
medicine, embarks on a study to assess the effects of a low saturated
fat diet compared to a high saturated fat diet on participants’ blood
cholesterol levels. During the enrollment process, potential participants
are presented with consent forms. However, these forms are lengthy
and filled with complex medical jargon, which may hinder participants’
understanding of the study’s implications. As a result, many individuals
may not fully comprehend the risks, benefits, and their rights as
participants.
* Question: What ethical concerns arise from the consent process in
this study?

Question 2

N=1
Evaluating the Effect of a Low-Carbohydrate Diet on Blood Glucose
Control in a Patient with Type 2 Diabetes:
o Scenario: A dietitian is working with a patient diagnosed with type 2 diabetes
who wants to improve blood sugar control through dietary changes.
o N=1 Design: The dietitian can apply an n=1 design by assessing the patient’s
blood glucose levels before starting a low-carbohydrate diet (baseline
data). Then, the patient follows the low-carb diet for several weeks, during
which blood glucose levels are monitored. Afterward, the dietitian could switch
the patient back to their usual diet for a period (removal of the intervention) to
observe any changes in blood glucose.
o Application in Practice: This allows the dietitian to determine whether the
low-carb diet specifically benefits the patient’s blood sugar control, and if
the intervention needs further modification based on the individual’s response

Question 3

n=1
Testing the Impact of Fiber Supplementation on Digestive Health
o Scenario: A patient reports frequent constipation and wants to try increasing
their fiber intake to improve bowel regularity.
o N=1 Design: The dietitian records the patient’s bowel movements over a
baseline period (without fiber supplementation). Then, the patient is asked to
consume a daily fiber supplement (e.g., psyllium) for four weeks. The
practitioner tracks any changes in bowel movement frequency, stool
consistency, and overall digestive health. To verify the results, the fiber
supplement could be removed to see if constipation returns (return to baseline).
o Application in Practice: This design helps the practitioner determine if the
fiber supplement is effective for the specific patient’s digestive health and
adjust the treatment accordingly.
