The staff nurse who works at a pediatric clinic located in the northeast part of the U.S. reviews the findings of a study conducted by a nurse researcher in the southwest part of the U. S.. Findings of the study indicate that the nutritional status of hispanic children ages 6 to 20 months is better for those who receive vitamin A supplements twice annually than it is for those who receive vitamin A supplements only once annually. Based on these findings, which action is most important for the staff nurse to take?
Replicate the study using white children from the pediatric clinic as subjects.
Propose initiating a policy of administering vitamin A twice annually to children ages 6 to 20 months.
Determine how the nurse researcher measured the subjects' nutritional status.
Compare the location where the study was conducted with the location of the pediatric clinic.
The Correct Answer is C
A. Replicating the study with a different population may be useful later but is not the immediate next step.
B. Implementing a policy change should be based on evaluating the study’s validity and relevance first.
C. Understanding how nutritional status was measured is crucial to evaluate the study’s applicability and reliability.
D. While location matters, measurement methods are more critical to assessing study quality
