- A nurse is collecting data during a prenatal visit. What two (2) questions would be asked to identify maternal drug abstinence? 2. A nurse is reinforcing teaching with a pregnant client who is diagnosed with iron deficiency anemia and has been prescribed iron supplements. List a statement if made by the client would indicate an understanding of the teaching. 3. A nurse is caring for a newborn with hyperbilirubinemia who has been prescribed phototherapy. Identify three (3) interventions the nurse should institute for this client?Please help me answer An Egg Production Company recently found that eating eggs does not increase a person’s blood serum cholesterol. Five hundred subjects participated in a study that lasted for 2 years. The participants were randomly assigned to either no-egg group or a moderate-egg group. The blood serum cholesterol levels were checked at the beginning and end of the study. Overall, the groups’ levels were significantly different. The company reminds that eating egg is healthy if done in moderation. Many of the previous studies relating eggs and high blood serum cholesterol jumped to improper conclusion. Using this information, answer the following questions: What prompted the study? What is the population under study? Was a sample collected? What was the hypothesis? Were data collected? Were any statistical tests run? What was the conclusion?Paper Assignment A study was conducted on patients with liver disease and some of their observations were included in the attached excel sheet. Use the dataset provided to answer the following questions: Q. 1. Write a statistical summary for participants' demographic and health details that include important variables such as Albumin Level, Age, Gender, Systolic BP, and Smoking Status. Point- 5 Q. 2. Compute most appropriate measure of central tendency and dispersion to report the variable Albumin level. Point- 2 Q. 3. (a) What is the appropriate statistical test to identify the significant difference between Gender groups and patients' Albumin level? (b) Write down the assumptions of the proposed statistical test. (c) Formulate null hypothesis & alternative hypothesis for such an association. Point-3
- QUESTION 1 Match each description to the correct study design. Study designs may be used more than once. ◆ Incidence data is not available with this study design, so an odds ratio is an appropriate measure of association to calculate. ◆ This study design allows for the evaluation of multiple outcomes. ◆ The temporal sequence between the exposure and outcome is clear for this study design; therefore, incidence data is available and a risk ratio can be calculated. ◆ With this study design, exposure status is assessed, and then participants are followed up over time to see who develops the outcome. ◆ Recall bias is a common issue with this study design because exposure information is collected from the past.
