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:
A significance level of p<.031 is relatively lenient and might result in a higher chance of obtaining statistically significant results by chance. A sample size of 54 subjects is moderate but may not provide the greatest support for the findings.
Choice B rationale:
A significance level of p<.01 is still relatively lenient, and a sample size of 15 subjects is relatively small. While p<.01 is more stringent than p<.031, it does not provide as strong statistical support as the options with lower p-values.
Choice C rationale:
This is the correct answer. A significance level of p<.001 is highly stringent and indicates a very low probability of obtaining the observed results by chance. A sample size of 73 subjects is relatively large, which enhances the reliability of the findings. This combination provides the greatest statistical support for the reported findings.
Choice D rationale:
A significance level of p=.301 is not stringent at all and would likely result in non-significant findings even with a small sample size of 24 subjects. This choice does not provide strong statistical support for the reported findings.
Correct Answer is C
Explanation
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.
