evaluation of nonpharmacologic interventions and sleep outcomes in hospitalized medical and surgical patients a nonrandomized controlled trial. You are the supervisor of an oncology unit and your unit council is working on a program to improve sleep in hospitalized patients. Your team begins with a review of the literature and have found that eye masks and ear plugs were effective in several studies. The team presents the attached article to you. Answer the following questions to evaluate the recommendations of the article: What is the research question? Be specific. What is the gap in the literature the study aims to address? The required sample size to find statistically significant results was calculated and found to be 286 patients in each group. Did the study meet the sample power calculation? How does this affect the results of the study? Look at the “Patient Reported Sleep Disturbing Factors” section on page 5. Summarize the differences in sources of sleep disturbance between the two groups. Look at the use of sleep aids on page 7-9. Based on these results, would you recommend implementing a similar package on your unit? Based on the results and discussion, how would you guide your staff? What is the number one intervention you would recommend? Explain your rationale.

The function $h$ satisfies $h(x) = \frac{10cos(x)}{1 - (f(x))^5}$ for $x \neq \frac{\pi}{2}$. It's known that $\lim_{x \to \frac{\pi}{2}} h(x)$ can be evaluated using L'Hopital's Rule. If $\lim_{x \to \frac{\pi}{2}} h(x) = \frac{1}{50}$ then what is $f'(\frac{\pi}{2})$? Note: The answer is an Integer
