What is the independent variable in this research question?
Clients aged 20 to 30 years.
Antipsychotic-induced weight gain.
Educational intervention.
Diagnosis of schizophrenia.
The Correct Answer is B
Choice A rationale:
Clients aged 20 to 30 years is not the independent variable in this research question. It is likely part of the study's population or sample characteristics but not the variable being manipulated or studied.
Choice B rationale:
This is the correct answer. Antipsychotic-induced weight gain is the independent variable in this research question because it represents the factor or condition that the researcher is manipulating or studying to determine its effect on the outcome variable (pain relief when used in conjunction with oral analgesics).
Choice C rationale:
Educational intervention is not the independent variable in this research question. It is the intervention or treatment being applied to the participants and is more likely the dependent variable, as its effectiveness is being assessed.
Choice D rationale:
Diagnosis of schizophrenia is not the independent variable in this research question. It is a participant characteristic that may influence the study's results but is not the variable being manipulated or studied in this context.

Correct Answer is A
Explanation
Choice A rationale:
This study is experimental because it involves the manipulation of an independent variable (participation in a specified 3-month strenuous exercise program) to assess its impact on a dependent variable (Hemoglobin A1c findings) in two groups (participants and non-participants).
Choice B rationale:
An exploratory study typically aims to explore a new topic or area and may involve surveys, interviews, or observations to generate hypotheses and ideas. It does not necessarily involve an experimental design.
Choice C rationale:
A correlational study examines the relationship between variables but does not involve experimental manipulation of an independent variable.
Choice D rationale:
A developmental study typically investigates changes or development over time, such as in child development, but does not necessarily involve experimental manipulation of variables.
Correct Answer is A
Explanation
Choice A rationale:
This statement is appropriate for the results section of a research article because it presents a specific statistic (4.5% of men aged 20 and above) related to the research topic (anginal pain). It also includes the source (American Heart Association) and the year (2002), providing clear and concise information about the prevalence of anginal pain in a specific population.
Choice B rationale:
While the statement about screening for anginal pain in individuals over the age of 50 is related to the research topic, it seems more like a recommendation or discussion point rather than a specific result obtained from the study. Such recommendations are typically found in the discussion or conclusion sections of research articles.
Choice C rationale:
Mentioning the number of subjects who volunteered and signed informed consent documents (68 subjects) is important but belongs in the methods section of a research article, not the results section. The results section should focus on the findings and data obtained from the study.
Choice D rationale:
Providing the percentage of subjects who reported experiencing anginal pain (60.3%) is relevant to the research topic, but it lacks context, such as the sample size or any statistical analysis. This type of information is better suited for the results section when accompanied by appropriate details and statistical analysis.
