A nurse is considering the use of restraints. The nurse should:

Choice A rationale
Poor balance and muscle weakness are significant risk factors for falls among older adults. These conditions can make it difficult for individuals to maintain stability and recover from a loss of balance, increasing the likelihood of falls.
Choice B rationale
Vision impairment is a well-known risk factor for falls. Poor vision can make it difficult for individuals to see obstacles and navigate their environment safely, leading to an increased risk of falls.
Choice C rationale
Medications that cause dizziness are a common risk factor for falls. Many medications, including those for blood pressure, pain, and anxiety, can have side effects that affect balance and coordination, increasing the risk of falls.
Choice D rationale
Regular physical activity is not a risk factor for falls. In fact, regular exercise can improve strength, balance, and coordination, reducing the risk of falls. Physical activity is often recommended as a preventive measure to help older adults maintain their mobility and independence.

Choice A rationale
Quasi-experimental research involves the manipulation of an independent variable to determine its effect on a dependent variable, similar to experimental research. However, quasi-experimental designs lack random assignment to groups, which can limit the ability to infer causality. Despite this limitation, quasi-experimental designs are valuable for studying causal relationships in real-world settings where random assignment is not feasible.
Choice B rationale

Correlational research examines the relationship between two or more variables without manipulating any variables. It does not involve the manipulation of an independent variable or the use of control groups, making it distinct from quasi-experimental research.
Choice C rationale
Qualitative research focuses on exploring and understanding the meaning and experiences of individuals through methods such as interviews, observations, and content analysis. It does not involve the manipulation of variables or the use of experimental designs, making it distinct from quasi-experimental research.
Choice D rationale
Quantitative research involves the collection and analysis of numerical data to identify patterns, relationships, and trends. While quasi-experimental research is a type of quantitative research, not all quantitative research involves quasi-experimental designs. Quantitative research can also include experimental, correlational, and descriptive designs.
