Which study would most likely be conducted using a qualitative methodology?
Descriptive study on coping mechanisms employed by family caregivers.
Prospective study on the long-term effects of chronic fatigue syndrome.
Phenomenological study of hardiness of clients with terminal diseases.
Epidemiological study regarding AIDS infection rates in a community.
The Correct Answer is C
Choice C rationale:
Phenomenological study of hardiness of clients with terminal diseases. Rationale: Qualitative research methodologies, such as phenomenology, are often used to explore and understand the lived experiences, perceptions, and meanings that individuals attach to specific phenomena. In this case, a phenomenological study is the most suitable approach to explore the "hardiness" (a subjective and experiential concept) of clients with terminal diseases.
Choice A rationale:
Descriptive study on coping mechanisms employed by family caregivers. Rationale: Descriptive studies typically aim to provide a comprehensive overview or description of a particular phenomenon. While this could involve qualitative data, the focus is on describing rather than deeply exploring subjective experiences, which is more aligned with quantitative methods.
Choice B rationale:
Prospective study on the long-term effects of chronic fatigue syndrome. Rationale: Prospective studies typically involve the collection of quantitative data over time to assess outcomes and relationships. Long-term effects of chronic fatigue syndrome may require quantitative measurements rather than in-depth exploration of experiences.
Choice D rationale:
Epidemiological study regarding AIDS infection rates in a community. Rationale: Epidemiological studies are primarily quantitative and aim to investigate patterns and determinants of disease in populations. This approach does not typically involve qualitative methods.

Correct Answer is A
Explanation
Choice A rationale:
True random sampling. True random sampling ensures that each client discharged from the postoperative orthopedic unit after joint replacement surgery has an equal and independent chance of being selected for the study. This approach minimizes bias and enhances the generalizability of the study findings to the entire population of interest.
Choice B rationale:
Stratified random sampling involves dividing the population into subgroups (strata) and then randomly selecting samples from each stratum. While this approach can be useful for ensuring representation of specific subgroups, it may not be necessary if the goal is to have an equal chance of participation for all clients.
Choice C rationale:
Convenience sampling involves selecting participants based on their availability and accessibility. It is not suitable for this study, as it may introduce bias and not ensure equal chances of participation for all clients.
Choice D rationale:
Quota sampling involves selecting participants based on predefined quotas for specific characteristics. It is not the most suitable method for ensuring equal chances of participation for all clients in this study.
Correct Answer is B
Explanation
Choice B rationale:
Experimental. Rationale: An increase in the number of subjects during the study is a characteristic of an experimental design. Experimental studies often involve the random assignment of subjects into groups and can include adding or recruiting more subjects as the study progresses to increase statistical power.
Choice A rationale:
Quantitative. Rationale: Quantitative research encompasses various research designs, including experimental, quasi-experimental, and non-experimental. The increase in the number of subjects alone does not specify the design as quantitative; it's more related to the experimental aspect.
Choice C rationale:
Quasi-experimental. Rationale: Quasi-experimental designs are similar to experimental designs but lack randomization. The increase in the number of subjects during the study is not a defining characteristic of quasi-experimental designs.
Choice D rationale:
Qualitative. Rationale: Qualitative research focuses on understanding and interpreting experiences, perceptions, and phenomena rather than experimenting with variables or increasing the number of subjects during a study. The increase in subjects is not indicative of a qualitative design.
