HESI Nursing Research II ( 54 Questions)
Which study design allows for manipulation of independent and dependent variables?
This study design allows for the manipulation of independent and dependent variables. In this case, the independent variable is the type of pain management (PCA-delivered narcotics vs. intermittent IM narcotics), and the dependent variable is the range of motion following joint replacement surgery. The researcher can control and manipulate the type of pain management administered to the participants, making it an experimental study design.
Providing logbooks to clients with fibromyalgia to record their actions does not involve manipulation of independent and dependent variables. It is an observational or self-report study design where participants' actions are recorded but not actively manipulated by the researcher.
Conducting interviews with nurse managers about their job satisfaction does not involve manipulation of independent and dependent variables. It is an observational or qualitative study design focused on gathering information and identifying themes but not manipulating variables.
Randomly selecting medical records to identify the frequency of discharges to skilled nursing facilities is an observational study design. It does not involve manipulation of independent and dependent variables but rather the collection of existing data from medical records.
Choice A rationale:
This study design allows for the manipulation of independent and dependent variables. In this case, the independent variable is the type of pain management (PCA-delivered narcotics vs. intermittent IM narcotics), and the dependent variable is the range of motion following joint replacement surgery. The researcher can control and manipulate the type of pain management administered to the participants, making it an experimental study design.
Choice B rationale:
Providing logbooks to clients with fibromyalgia to record their actions does not involve manipulation of independent and dependent variables. It is an observational or self-report study design where participants' actions are recorded but not actively manipulated by the researcher.
Choice C rationale:
Conducting interviews with nurse managers about their job satisfaction does not involve manipulation of independent and dependent variables. It is an observational or qualitative study design focused on gathering information and identifying themes but not manipulating variables.
Choice D rationale:
Randomly selecting medical records to identify the frequency of discharges to skilled nursing facilities is an observational study design. It does not involve manipulation of independent and dependent variables but rather the collection of existing data from medical records.
