The nurse is using an experimental design to investigate this research question: What is the effect of antibacterial sutures versus standard sutures on the incidence of wound infection in a randomized sample of children 5 to 10 years of age? Which children should be excluded from participating in this study? (Select all that apply.).
7-year-olds with attention deficit hyperactivity disorder (ADHD).
5 to 10 year-olds who are type 1 diabetics.
10-year-olds with dyslexia.
First graders at a public school who are recent immigrants.
5 to 10-year-olds with leukemia.
Correct Answer : B,E
Choice A rationale:
7-year-olds with attention deficit hyperactivity disorder (ADHD) should not necessarily be excluded from participating in the study solely based on their ADHD diagnosis. Exclusion criteria should be related to factors that could significantly confound the study's results or pose additional risks to the participants.
Choice B rationale:
5 to 10-year-olds who are type 1 diabetics should not be automatically excluded from the study, as their diabetic status is not directly related to the study's research question about the effect of antibacterial sutures on wound infection.
Choice C rationale:
10-year-olds with dyslexia should not be excluded from the study unless dyslexia is directly related to the outcomes being measured (e.g., cognitive function) or if it poses a risk to the participant's ability to understand and comply with study requirements.
Choice D rationale:
First graders at a public school who are recent immigrants should not be automatically excluded from the study based solely on their immigrant status or grade level. Exclusion criteria should be based on factors relevant to the study's research question and potential risks.
Choice E rationale:
5 to 10-year-olds with leukemia should be excluded from the study, as they have a medical condition (leukemia) that directly affects the outcome being studied (wound infection). Their compromised immune systems could significantly confound the results.

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 B
Explanation
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.
