NURSING DL-F, Applied Nursing Research Quiz 6 (Questions With Verified Answers) 2023/2024. Surveys that allow respondents to listen to questions over headphones and enter their responses via a keyboard use which technology? Selected Answer: A. AudioCASI Answers: A. AudioCASI B. CAPI C. SAQ D. CATI Response Feedback: Audio-CASI (computer-assisted self-interview) involves administering the survey questions via headphones and having respondents enter their answers onto a keyboard. This approach is useful if literacy and privacy are major concerns. In both CATI and CAPI, an actual interviewer asks the questions, either in person (computer-assisted personal interview) or over the telephone (computer-assisted telephone interview). SAQ is an acronym for self-administered questionnaire.  Question 8 5 out of 5 points What technique do researchers use to estimate how large a sample they need? Selected Answer: C. Power analysis Answers: A. Screening B. Stratificatio n C. Power analysis D. Weighting Response Feedback: In quantitative studies, researchers often use a power analysis to estimate sample size needs, which is a strategy for avoiding problems with statistical conclusion validity. The other terms are not relevant to sample size estimation.  Question 9 0 out of 5 points The APACHE system has been used in many nursing outcomes studies. What is the APACHE system? Selected Answer: A. A taxonomy of nursing outcomes Answers: A. A taxonomy of nursing outcomes B. A classification system of nursing interventions C. A global measure of client acuity, used to adjust outcomes for client risks D. A taxonomy of nursing diagnoses Response Feedback: Client outcomes vary in part because of differences in client conditions and comorbidities. The Acute Physiology and Chronic Health Evaluation (APACHE) system is a global measure that can be used to control for clients’ risks for poor outcomes in outcomes research. The Nursing Intervention Classification (NIC) classifies nursing interventions, and the Nursing Diagnoses Taxonomy classifies diagnoses. Nursing outcomes have also been classified (NOC).  Question 10 5 out of 5 points A nurse researcher used a systematic sampling plan in a study of adolescents’ health-promoting activities. The desired sample size was 200. The sampling interval was 250. The first element drawn at random was 196. What would the second element be? Selected Answer: B. 446 Answers: A. 450 B. 446 C. 646 D. 396 Response Feedback: The sampling interval is the standard distance between sampled elements, which in this case is 250. The first element drawn (196) plus the sampling interval (250) equals 446 as the second element.  Question 11 5 out of 5 points A nurse researcher used a randomized crossover design to test the hypothesis that watching a music video would improve the sleep quality of older adults with chronic insomnia. What type of trial was this? Selected Answer: A. A superiority trial Answers: A. A superiority trial B. An equivalence trial C. A sequential trial D. A noninferiority trial Response Feedback: The researcher undertook a standard superiority trial in which it was hypothesized that the music video was superior to the absence of the music video (i.e., would lead to improvements). A noninferiority trial tests whether an intervention is no worse than (not inferior to) a reference treatment. Equivalence trials test whether alternative interventions are equal. A sequential clinical trial involves ongoing analysis of data to see if the trial can be stopped based on available evidence.  Question 12 5 out of 5 points A nurse researcher identified her accessible population as women with high-risk pregnancies in the state of New York. Which group might be her target population? Selected Answer: A. All women with high-risk pregnancies in the United States Answers: A. All women with high-risk pregnancies in the United States B. All pregnant women in northeast United States C. All pregnant women in the state of New York D. All women with high-risk pregnancies in the town of Greenfield, New York Response Feedback: The accessible population is the aggregate of cases that conform to designated criteria and that are accessible—in this case, women with high-risk pregnancies in the state of New York. The target population is a broader group—the aggregate of cases about which the researcher would like to generalize the findings. In this case, the broader group is women with high-risk pregnancies in the United States. Women who do not have high-risk pregnancies would not meet the implied criterion for being in the study.  Question 13 5 out of 5 points Evaluation research can address many different objectives. Which type of analysis provides information about how a program being evaluated actually functions? Selected Answer: B. A process analysis Answers: A. A cost analysis B. A process analysis C. An impact analysis D. An outcome analysis Response Feedback: A process (or implementation) analysis provides in-depth descriptive information about the process by which a program gets implemented and how it actually operates. An outcome analysis examines whether the program is meeting its objectives, and an impact analysis examines program effects. A cost analysis considers the cost of operating the program, usually in relation to its benefits.
