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 C
Explanation
Choice A rationale:
An experimental study should be designed that compares absenteeism rates with random versus non-random staff assignment methods. Rationale: While an experimental study could provide valuable data, it may not be the best approach in this situation. The question pertains to the "fairest method" for floating staff nurses, which involves subjective elements such as staff perceptions and experiences. An experimental study may not capture the nuances of fairness effectively.
Choice B rationale:
The nurse-manager should investigate the float procedures used by other units and choose the most commonly used method for the ICU. Rationale: This choice involves benchmarking against other units, which can be a useful approach. However, it assumes that the most commonly used method in other units is the best fit for the ICU, which may not be the case. It also doesn't involve direct input from the staff nurses in the ICU.
Choice C rationale:
A qualitative study should be implemented that includes focus group interviews with 6 staff nurse volunteers who recently floated to other units. Rationale: This choice is the best approach because it involves gathering qualitative data directly from staff nurses who have experienced floating to other units. Focus group interviews allow for in-depth exploration of their experiences and perceptions, which are critical in determining what staff consider to be the fairest method. It also incorporates staff input into the decision-making process.
Choice D rationale:
The staff nurses should use their collective experience to propose a float assignment policy that is congruent with overall hospital staffing policies. Rationale: While involving staff input is important, relying solely on the collective experience of staff nurses may not yield the most objective and comprehensive solution. It may also lead to biases or preferences that are not aligned with best practices.
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.
