Exam 8: Clarifying Quantitative Research Designs

Multiple replications of an initial study conducted in different populations produce findings that do not match those in the initial study.The initial study may lack which type of validity?

When using Consolidated Standards for Reporting Trials (CONSORT)guidelines to critically appraise a randomized controlled trial (RCT),the nurse will make sure that the study

A nurse researcher understands there are numerous concepts relevant to quantitative research designs.What concept best describes the following example,"Patient diagnosis,age,pre-surgical condition,and complications after surgery are interrelated causes of the length of patients' hospital stays"?

A nurse researcher conducts a study to determine whether women who breastfeed their infants experience better sleep in the first two postpartum months.This study will employ which type of research design?

A researcher conducts a quasi-experimental study to determine whether there is improved weight gain among premature infants who are fed according to cue-based protocols.The researcher trained neonatal intensive care nurses to apply cue-based feeding to orally fed infants and notes a statistical difference in weight gain between infants fed according to cue-based protocols and those fed according to standard protocols.The reviewer notes that components of cue-based feedings are not clearly identified.This is a threat to

Which type of research design focuses on implementation of a treatment by the researcher?

Which statement is true about a quantitative research design?

A researcher wishes to study the effects of effective sleep hygiene on sleep quality and behavior among children diagnosed with attention deficit disorder.To minimize mono-operation bias,the researcher will

To increase participation among potential subjects of a larger population,the researcher will

A researcher develops a 7-point Likert scale to evaluate feelings of well-being in patients who are undergoing chemotherapy.The researcher administers this measure to other similar patients in other medical centers.This is done to

In a quasi-experimental study design,the group that receives standard care is usually referred to as the

A researcher reviews demographic characteristics of potential study subjects,such as age and gender,to determine whether these characteristics may influence the outcome of the study.This is done to help ensure

Which of the following are true statements about randomized controlled trials (RCTs)? Select all that apply.

In a research study,ambulatory clinic nurses teach children with asthma how to monitor peak expiratory flow volumes and how to use metered-dose inhalers to determine whether asthma control scores improve.The researcher discovers inconsistencies in how these measures were taught and how well the children understood the concepts.This represents a lack of

A researcher theorizes a set of relationships among concepts used to describe why patients with chronic illness are often depressed.To test the accuracy of these hypothesized relationships,which type of study will be used?

A researcher conducts a study to examine possible contributors to glycemic control in a group of subjects who have type 2 diabetes mellitus in a local community.A convenience sample of patients includes patients from 28 to 65 years old who range in weight from normal to obese,with time since diagnosis ranging from several months to several years.To determine causality in this study,the researcher will
