HESI Nursing Research II ( 54 Questions)
In a study of hypertension among elementary school students, the systolic and diastolic blood pressure of each child in one school was measured one time at the end of a school year.
This is an example of which study design?
This is the correct answer. A cross-sectional study design involves collecting data from a sample of participants at a single point in time. In this case, the systolic and diastolic blood pressure of each child in one school was measured one time at the end of a school year, making it a cross-sectional study.
A quasi-experimental design typically involves an intervention or treatment, which is not described in this scenario. Quasi-experimental studies also often involve multiple measurements over time.
Comparative studies typically involve comparing two or more groups or conditions but may include multiple measurements over time. The scenario describes a single measurement at the end of the school year.
A prospective study typically involves following participants over time, collecting data at multiple points in the future. This scenario involves a single measurement at one point in time.
Choice A rationale:
This is the correct answer. A cross-sectional study design involves collecting data from a sample of participants at a single point in time. In this case, the systolic and diastolic blood pressure of each child in one school was measured one time at the end of a school year, making it a cross-sectional study.
Choice B rationale:
A quasi-experimental design typically involves an intervention or treatment, which is not described in this scenario. Quasi-experimental studies also often involve multiple measurements over time.
Choice C rationale:
Comparative studies typically involve comparing two or more groups or conditions but may include multiple measurements over time. The scenario describes a single measurement at the end of the school year.
Choice D rationale:
A prospective study typically involves following participants over time, collecting data at multiple points in the future. This scenario involves a single measurement at one point in time.
