The Chief Nursing Officer has now approved the device to be used in the Burn Unit. A new pain medication was shown to be effective in a group of osteoarthritis patients in a major metropolitan city and subsequently has been approved for use for all osteoarthritis patients nationwide. A new helmet law was implemented in a Midwestern state. In response to this new legislation, hospital X has begun to give free helmets to patients upon discharge. A second generation antihypertensive drug is FDA-approved and added to the DNP curriculum in a major university. Question 2 3.25 / 3.25 pts Which of the following examples demonstrates transferability? You read a research article that reported that music therapy decreased anxiety in preoperative patients.Subsequently you obtained approval to use music therapy at your hospital with pre-operative patients. You identify several key research studies in your hospitalâ&#x20AC;&#x2122;s searchable database and transfer them to your personal files. A nurse implements a new evidence-based intervention aimed at reducing ventilatorassociated pneumonia (VAP).He is unable to adhere to the demanding work schedule and is transferred to another unit. You conduct a randomized control trial (RCT) with a sample of Myasthenia Gravis patients. You are now able to apply this statistically significant RCT to the general population of Myasthenia Gravis patients. Question 3 3.25 / 3.25 pts All of the statements are true of transferability EXCEPT: If there are sufficient similarities between the research and our own clinical situation, we may be able to infer that the results of the research would be similar in our situation. When reading a research article, we note certain characteristics of the study and consider the applicability to our own clinical practice.

We must know as much as possible about the original research in order to determine if the results are applicable to our own practice. We can transfer or apply any study results to our own practice as long as the study was reliable and valid. Question 4 3.25 / 3.25 pts The concept of transferability is constantly applied in everyday life. Some examples include (Select all that apply) Correct! A professor sits in on a colleague’s class to see if he can apply new and effective teaching techniques in his own classroom. Correct! A busy nurse, wife and mother, on her day off watches a cooking show to determine what quick, easy and nutritious meals she can prepare for her family. An individual is engaged in a conversation with a friend about the benefits about a new vehicle that would add convenience to her own life. A neighbor tells you that he has come up with a new health plan for him and his family and that everyone in the world should adopt this same plan. Question 5 3.25 / 3.25 pts Examples of generalizability in everyday life include (Select all that apply) As health care professionals, we make the assumption that poor diet and lack of exercise puts individuals at risk for diseases such as diabetes and heart disease. Correct! In the United States, we make the assumption that everyone will drive on the right side of the road. We make the generalization that everyone in the United States speaks English and abides by American customs. We make the assumption that driving under the influence of drugs or alcohol can lead to accidents. Question 6 3.25 / 3.25 pts You overhear two nurse colleagues talking about a research study on Diabetes, recently conducted at your hospital. You hear them say, “The results showed that children with Type II Diabetes responded well to a new anti-hyperglycemia drug at our hospital. We can now generalize our findings to women with pregnancy-induced Diabetes.” You are excited to join their conversation. What is the most appropriate response?

“I couldn’t help but to overhear your conversation about our exciting Diabetes research study. I am excited because women all over the world with pregnancy-induced Diabetes will finally have an effective drug to control their hyperglycemia.” “I couldn’t help but to overhear your conversation about our exciting Diabetes research study. Since our study was aimed at children with Type II Diabetes, we cannot generalize our results women with pregnancy-induced Diabetes.” “I couldn’t help but to overhear your conversation about our exciting Diabetes research study. We can generalize our findings because we used a nonprobability sample.” “I couldn’t help but to overhear your conversation about our exciting Diabetes research study. Generalization is feasible because we have a very large sample size.” Question 7 3.25 / 3.25 pts You read a research article on a study aimed at reducing central line associated blood stream infections (CLBSIs).The authors report that a detailed protocol using chlorhexidine was statistically significant in reducing CLABSIs by 98% in their study sample of 5678 Neonatal Intensive Care Unit (NICU) patients. Which of the following statements is accurate? The findings from the CLABSI study can be applied or transferred to a neonatal intensive care unit at your hospital to reduce CLABSIs. While the findings are impressive and statistically significant, further research is warranted in NICU patients. The findings can be generalized to an adult ICU in a Magnet hospital in Beirut, Lebanon. The findings from this study can be generalized to a general Respiratory ICU unit at the same hospital. Question 8 3.25 / 3.25 pts When reviewing research study results aimed at reducing fall rates among elderly patients at hospital X, which statement most likely indicates representativeness of the sample related to the general target population at large? The sample consisted of 50 elderly patients on Central Nervous System depressant drugs that put the study patients at risk for falls. The sample consisted of a randomly selected subset of 6000 elderly patients over a 1-year time frame. The sample consisted of 200 elderly outpatients on a strict health regimen consisting of probiotics, exercise and adequate nutrition and not taking any prescription drugs. The sample consisted of 100 elderly patients whom ranged in age from 65-70 years in the study over a 1 week period. Question 9 3.25 / 3.25 pts

You have been asked to select a random sample of 1000 patients in your 5-hospital system for a proposed study aimed at reducing hospital readmissions. Each of the 5 hospitals has 600 beds. Which of the following approaches is best? You spend a week going from room to room in each hospital, explaining the study to each patient and asking for volunteers for the study, making a list of the 1000 patient names who agree to participate. You ascertain a list of all patient names and room numbers from each of the 5 hospitals and call each patient room asking for patient volunteers for the study. You post flyers at the nursing stations of each unit at all 5 hospitals and explain the proposed study to the nursing staff. The nursing staff will recruit patients and contact you with the names and contact information for each patient who is interested up to 1000. You obtain a list of all patient names in each of the 5 hospitals in the system and assign each name a numerical value. Using a table of random numbers, you select 1000 numbers (patients). Question 10 3.25 / 3.25 pts A nurse colleague wants to survey nurses on his unit to determine the level of RN satisfaction. He proposes to administer a pre-test survey and design a practice change based on the results. He then proposes to administer a post-test to determine if the new intervention was effective. You recognize right away that the sample will be a nonprobability, nonrandom or convenience sample. All of the statements below are accurate EXCEPT: A convenience sample in this case is appropriate because the nurse simply wants to make an effective practice change on his unit directly. Findings from this proposed study cannot be generalized to the larger population of RNs. Findings from this proposed study can be transferred to other units in the hospital. The proposed study will not be reliable or valid because the sample will not be randomly selected.

NR714 Week 7 Module 2 Quiz Latest 2017 November (all correct answers) Question 1 3.25 / 3.25 pts In the hospital research committee, the group discusses an idea for a research proposal aimed at improving patient outcomes related to prevention of hospital acquired dermal ulcers. One of the team members asks why a power analysis must be done. What is the best response? The power analysis must be conducted for every research study to meet national regulations. The power analysis is not a requirement and foregoing this analysis will not have an impact on the study. The power analysis is not necessary as long as the research investigator makes sure as many subjects are included in the study as possible. The primary goal of the power analysis is to decide how large a sample is needed to enable statistical judgments that are accurate and reliable. Question 2 3.25 / 3.25 pts You are reading a research article on a nursing study directed at gathering knowledge from 100 new mothers on the benefits of breast feeding. You see that a Likert scale was used where 1 indicates no knowledge and 5 indicates a lot of knowledge. The data reveals sixtyseven 1s and twenty-eight 5s, with three 2s and two 4s. You know that this study as a wide _______ of scores. percentage standard deviation variance range Question 3 3.25 / 3.25 pts As you read more closely into the study results, you see that the scores of the new nursing mothers are very far from the mean or average score. You think back on your research class and realize that that this means that the study scores have a large _______________. range standard deviation variance power

Question 4 3.25 / 3.25 pts Another study results show all of the scores in the center of the distribution curve. In other words, the average or mean scores are 50%. This means that the study has very little or limited (select all that apply) Range Skewness Variability Reliability Question 5 3.25 / 3.25 pts You are talking to a nurse colleague who is proposing to conduct an innovative research study using warming blankets on patient pre-surgery to determine if post-operative complications are reduced. He tells you that he does not plan to perform a power analysis because he is including all patients scheduled for surgery over the next 6 months which will give him a sample size well over 4000 subjects. Which of the responses below is the most appropriate? “Performing a power analysis helps to make sure that more subjects are not included than is necessary because excess resources may be used with little added benefit to the study.” “That is great that you have such a high number of subjects, as the large number of subjects will increase the reliability of your study.” “Too many subjects will decrease the reliability of the study, regardless of cost.” “That is a good sample size, but did you get approval for subject payment to make sure there is enough money in the research budget?” Question 6 3.25 / 3.25 pts You overhear nurse colleagues talking just before an Institutional Review Board (IRB) meeting? They are debating as to which topic is more critical in research, cost effectiveness or scientific usefulness of the study. As a more seasoned researcher, you join the conversation in order to help resolve the debate. Which of the responses below is best? “Scientific usefulness in research far outweighs cost effectiveness.” “Cost effectiveness is paramount. After all, without financial stewardship and resources, the study cannot effectively be conducted.” “Neither of those issues are important. Cost should not impede scientific inquire. Further, we will not know how useful the research is until we get results.” “You are both correct. Cost effectiveness in research is equally as important as scientific usefulness.” Question 7 3.25 / 3.25 pts

You are leading the Research Council and part of the agenda is to report to the team that a power analysis will be conducted prior to starting the study. The rationale for conducting the power analysis is to (Select all that apply) decide how large a sample is needed to enable statistical judgments that are accurate and reliable. avoid making a Type II Error. avoid having a sample larger than necessary. avoid making a Type I Error. Question 8 3.25 / 3.25 pts You have been asked to present the four major measures of variability to your hospital research team, including: (Select of all Apply) range and interquartile range skewness variance standard deviation Question 9 3.25 / 3.25 pts A Nurse Practitioner tells you that she wants to conduct a research study and set the alpha level to <0.05. Which type of error is she trying to avoid? Type II Error – she will have a less than 5% chance of incorrectly accepting the null hypothesis Type I Error – she will have a 95% chance of incorrectly rejecting the null hypothesis Type I Error - she will have a less than 5% chance of incorrectly rejecting the null hypothesis Type II Error – she will have a 95% chance of incorrectly accepting the null hypothesis Question 10 3.25 / 3.25 pts A colleague tells you that she wants to conduct a study, but is afraid of incorrectly rejecting the null hypothesis. In other words, she does not want to make an error and reject the notion that the medication is not effective (accepting that a new chemotherapeutic agent is effective when it is not). This could mean that a cancer patient is taking a drug that is not killing cancer cells which would be detrimental to the patient. This nurse is justified in her fear of making which type of error? Type IV Type III Type I

Type II

NR714 Week 7 Module 3 Quiz Latest 2017 November (all correct answers) Question 1 3.25 / 3.25 pts In trying to set an appropriate range of 95% that focuses on the population used to estimate a characteristic of a population where the numbers can be stated with the probability that the population characteristic is included between them, we are setting a t-test limit confidence level population sample Question 2 3.25 / 3.25 pts The term that captures the entire target group of individuals under study is referred to a placebo sample confidence interval population Question 3 3.25 / 3.25 pts You are conducting a research study on the effectiveness of normal saline administered subdermally compared to lidocaine to reduce pain during IV insertion. If subjects getting lidocaine are in the experimental group, the subjects getting the inert normal saline are in the

control group preliminary group sample group research group Question 4 3.25 / 3.25 pts The same colleague asks you now to define the sample in research. Which is the most accurate response? “The sample is a subset of the population that the researcher intends to study.” “The sample is a group of individuals used in a pilot study before the actual study is conducted.” “The sample is a small group of study participants who drop out of a research study.” “The sample refers to a partial subject payment paid to study participants at the start of a research study.” Question 5 3.25 / 3.25 pts In the inner city study investigating the impact on air quality on childhood asthma, what is the study sample? “The study sample is a randomly selected subset of all inner city school-aged children in city X.” “The study sample is the entire group of inner city school-aged children in city X.” “The study sample is a small self-selected group of inner city school-aged children diagnosed with asthma.” “The study sample is the group of all inner city school-aged children with asthma and their parents.” Question 6 3.25 / 3.25 pts If a researcher tells you she achieved a narrow interval, in which there is little difference between lower and upper limits. The narrow confidence interval indicates an inaccurate measure of how well the true measure of the parameter is estimated. a satisfactory, but less desirable estimate than a wide interval. a less precise estimate than does a wide interval. a better and more precise estimate than does a wide interval. Question 7 3.25 / 3.25 pts

Let’s say that you are conducting a study on pain tolerance among men and women at a rural community hospital. Which of the following statements indicates the null hypothesis for your study? There will be a statistically significant difference in pain tolerance between the two groups. There will be a significantly higher pain tolerance in women than men. There will be no difference in pain tolerance between the two groups. There will be a significantly lower pain tolerance in women than men. Question 8 3.25 / 3.25 pts You are on a research team in a major urban medical center. The team is proposing to conduct a research study on investigating the effectiveness of a new beta blocker medication to treat hypertension. The study will have two groups of subjects. One group will range in age from 40-65 years, while the second group will range in age from 65-80 years. You already know that a t-test will be performed to determine differences between the two groups related to decrease in hypertension as a result of taking the new beta blocker. What statement represents the best rationale for performing a t-test? It does not matter what the difference in blood pressure is between the younger and older groups. It is important to know the differences in blood pressure between the two groups to determine effectiveness of the beta blocker in younger and older persons. It is not necessary to perform the t-test because we already know the two groups are different. It is important to perform the t-test because it will confirm that the beta blockers are more effective in the older group. Question 9 3.25 / 3.25 pts Let’s say in the previous beta blocker study, the t-test determined that the average or mean blood pressures for each group were as follows. The younger group had a 20% decrease in blood pressure by using the beta blocker.The older group had a 50% decrease in blood pressure. What might these results be telling us? Select all that apply. Correct! The beta blockers were shown to be more effective in the older adults than younger adults. The beta blockers were effective in both younger and older adults. The beta blockers were not effective in either younger or older adults. While the beta blockers were shown to be effective in both groups, they were more effective in the older adult group. Question 10 3.25 / 3.25 pts

You are reading a research article about the effectiveness of exercise on lowering cholesterol. The study used two groups, where one group was given an exercise regime, while the other group avoided exercise. What is the null hypothesis for this study? There will be a statistically significant difference between the exercise and the sedentary groups. There will be no statistically significant difference between the exercise and the sedentary groups. There will be a statistically significant decrease in cholesterol in the sedentary group. There will be a statistically significant decrease in cholesterol in the exercise group.

NR714 Week 7 Module 4 Quiz Latest 2017 November (all correct answers) Question 1 3.25 / 3.25 pts You have been asked to be a guest speaker on prevalence and incidence rates at a local university. What is the best introductory statement to begin your lecture? “Prevalence rates are very different from incidence rates and will be discussed in two different classes.” “Prevalence and incidence rates are the same concept; therefore, we need only discuss one”. “Prevalence rates and incidence rates are related, but distinct concepts.” “Incidence rates are often expressed in fractions or ratios.” Question 2 3.25 / 3.25 pts You are a scientific voting member on a community hospital institutional review board. You are the primary reviewer for a research study aimed at reducing the occurrence of Diabetes among young adult African-Americans in the U.S. Part of the background information in the protocol states that in 2010, 18.7% of all African-Americans with Diabetes were aged 20 years and younger. You explain to the board that this percentage represents prevalence of Diabetes in African-American young adults.

incidence of Diabetes in African-American young adults. the mean or average number of Diabetes cases in African-American young adults. a genetic component of Diabetes cases in African-American young adults that cannot be changed with diet. Question 3 3.25 / 3.25 pts A nurse researcher tells you about a research study that reported 15,600 new cases of Type I Diabetes annually between 2002 and 2005. She says that this is an unacceptable prevalence rate for Type I Diabetes and that as a Nurse Practitioner, she has an obligation to provide patient education in her practice. What is your best response to her? “I agree that we need to make every effort to reduce this prevalence rate.” “I agree that we should focus our attention on reducing the incidence of Type I Diabetes. 15,600 new cases indicates incidence rather than prevalence.” “Those may be cases related to genetics, so providing education may not help’” “That is a small prevalence rate, so I would rather provide education in other areas.” Question 4 3.25 / 3.25 pts You are asked to explain the difference between prevalence and incidence to the administration team at your hospital. Which is the best response? Incidence refers to new cases of a disease, while prevalence refers to existing cases of a disease. For example, the incidence rate is the number of new cases per population, while prevalence is the number of existing cases per population. Prevalence refers to existing cases of a disease, while incidence refers to new cases of a different disease within the population of interest. Prevalence refers to new cases of a disease, while incidence refers to existing cases of a disease. For example, the prevalence rate is the number of new cases per population, while the incidence is the number of existing cases per population. Prevalence refers to existing cases of a disease, while incidence refers to new cases of the same disease in a different population. Question 5 3.25 / 3.25 pts A nurse colleague confers with you regarding a research article he is reading aimed at reducing catheter-associated urinary tract infections (CAUTI). The authors report a baseline finding on the prevalence of CAUTIs in a large metropolitan hospital. Of the 325 patients who had indwelling urinary catheters, 18 were found to have a CAUTI. Which response below is indicative of prevalence in this population? There is insufficient information to determine the prevalence rate Without the hospital bed size, the prevalence rate will not be accurate 325/18 = 18.05

18/325 = 0.055 Question 6 3.25 / 3.25 pts The local Quickie Clinic is known to be busy and at capacity throughout the year. You are looking into the number of patients presenting with hypertension. Each year, 37,000 patients are seen and 20,000 of these patients are diagnosed with hypertension. What is the incidence of newly diagnosed patients each year? 20,000/37,000 = 0.54 20,000 37,000/20,000 = 1.85 37,000 Question 7 3.25 / 3.25 pts As a nurse researcher, you know that some cases of prevalence are reported per 100,000 people.
