A nurse is completing a client’s assessment.
Which of the following should the nurse consider as objective data?

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.

Choice A rationale
Fatigue is a subjective symptom reported by the client. It is based on the client’s personal experience and cannot be objectively measured or observed by the nurse. Therefore, it is not considered objective data.
Choice B rationale
Dizziness is also a subjective symptom reported by the client. It reflects the client’s personal experience and cannot be directly observed or measured by the nurse. As such, it is not considered objective data.
Choice C rationale
Numbness is another subjective symptom reported by the client. It is based on the client’s personal sensation and cannot be objectively measured or observed by the nurse. Therefore, it is not considered objective data.
Choice D rationale
Physical examination results are objective data. They are obtained through direct observation, measurement, and assessment by the nurse. Examples of objective data include vital signs, physical examination findings, and laboratory results. These data are reproducible and can be verified by other healthcare professionals.
