Abstract This paper is a quantitative critique of an article written to assess the link between bed rest and preterm delivery. The first section explores the research problem, the justification of the study and its importance to nursing, the conceptual framework, and the organization of the literature review. The second part discusses the methods used for the research including the study design, sampling, study protocol, data collection instruments, threats to internal and external validity, and approval by the relevant instructional review board. The results section presents the sample characteristics, the type of data collected, data analysis procedures, and a brief summary of the findings. The discussion section shows how the authors relate the findings to the study’s purpose, limitations of the study, and implications for practice. The last section is an overall presentation and the final summary of the study. Introduction The research problem was clearly stated in the paper. According to the authors, bed rest or other forms of activity restrictions are common practices used among pregnant mothers to avoid preterm birth. However, there is insufficient data to support the efficacy of this practice. Therefore, the authors sought to address this problem by quantitatively assessing whether physical activity restriction would affect preterm birth, which underscores the research problem. The justification for this study is that bed rest is a widely used obstetrical practice despite the paucity of data supporting its efficacy. Reduced physical activity during pregnancy is associated with some deleterious effects such as depression and stress, which might affect the wellbeing of the unborn child. Therefore, this study is justified as it established whether pregnant women should be put on bed rest. The study’s aim is stated, which was to assess whether physical activity is associated with preterm birth among pregnant women at high risk for preterm delivery. The authors did not give a theoretical or conceptual framework, but it could be implied from the study. Determining the association between bed rest and preterm birth would contribute significantly to evidence-based nursing practice among obstetricians, which underscores the conceptual framework. The framework is linked directly to the research purpose because they both seek to address the same issue of assessing the link between bed rest and preterm delivery. The research literature reviewed in the study is a mixture of both old and current sources even though the literature review section is missing. Throughout the paper, the authors referenced 33 sources, and 9 were published over 10 years before the publication of the current study. The rest were published after 2010, and thus they would be considered current. The literature review is organized logically with sources used in areas where they offer relevant support to the claims being made. Additionally, the literature review adequately supports the need for the study. For example, the authors referenced past studies, which had not shown a statistically significant difference in the risk of miscarriage among pregnant women placed under bed rest and the control group. Moreover, the authors used the literature review to show that the current evidence does not refute or support bed rest as an approach to red
