The researcher has a A doctoral degree from a prestigious university b Assembled a team of high-quality investigators c Published five previous studies on the same topic d 15 years of practice in the clinical specialty area ANS: C If a researcher has conducted several previous studies on the same topic as the current one and they are cited in the reference list (therefore published), this is extremely strong evidence of the feasibility of the current study A doctoral degree does demonstrate educational credentials that lend feasibility to the study, but the degree alone does not provide as much support as published studies If a researcher has conducted several previous studies on the same topic as the current one and they are cited in the reference list (therefore published), this is extremely strong evidence of the feasibility of the current study The use of a talented team is commendable and would probably make the study stronger, but does not provide as much support as previously published studies If a researcher has conducted several previous studies on the same topic as the current one and they are cited in the reference list (therefore published), this is extremely strong evidence of the feasibility of the current study The years of clinical practice are very valuable in developing clinically relevant research, but not provide as much support as published studies If a researcher has conducted several previous studies on the same topic as the current one and they are cited in the reference list (therefore published), this is extremely strong evidence of the feasibility of the current study DIF: Cognitive level: Analysis REF: p 158 27 An experienced, published researcher’s funded study is to recruit a sample of mothers with children under the age of 30 entering a shopping complex with $100 spending money The purpose of the study is to test the hypothesis that younger mothers will spend the money on themselves rather than on their children What are the possible issues with http://getbooksolutions.com the feasibility of this study? a Availability of subjects Test Bank Copyright © 2011 by Saunders, an imprint of Elsevier Inc 5-15 b Ethical violations c Researcher’s expertise d Money commitment ANS: A In using only one shopping complex, procuring a suitable, representative sample may be problematic The women who consent to participate would probably be a biased group There are no apparent ethical violations noted within the study The researcher’s expertise is clearly stated Because the research is funded, the money commitment to the sample is secured DIF: Cognitive level: Analysis REF: p 159 28 In which situation would the research and the null hypothesis be the same? a Researcher does not think that the research is going to mean anything b Researcher predicts that there will be no difference among the groups c Statistical analysis reveals a correlation coefficient of zero d Study has serious flaws and is declared null and void ANS: B The null hypothesis is the statistical hypothesis that tests for no relationship It is also used when the researcher predicts that there is no relationship between the variables If the researcher does not think the research is going to mean anything, it is probably best not to conduct it The null hypothesis is the statistical hypothesis that tests for no relationship It is also used when the researcher predicts that there is no relationship between the variables The correlation coefficient may be found to be zero; however, the researcher’s hypothesis may have been other than that The null hypothesis is the statistical hypothesis that tests for no relationship It is also used when the researcher predicts that there is no relationship between the variables There is no connection between finding serious flaws in a study and the research and null hypotheses The null hypothesis is the statistical hypothesis that tests for no relationship It is also used when the researcher predicts that there is no relationship between the variables DIF: Cognitive level: Application REF: p 174 29 One researcher wanted to investigate whether nursing students should take psychiatric http://getbooksolutions.com mental health nursing before they take medical surgical nursing Which of the following is a correctly stated objective of this study? a Do nursing students ultimately perform better on NCLEX® when they have had the content in psychiatric mental health nursing first or when they have the content in medical surgical nursing first? b Does putting the psychiatric mental health nursing content before medical surgical content better prepare nursing students to pass NCLEX®? c This research study examines whether having psychiatric mental health content before medical surgical content better prepares nursing students to perform well on their NCLEXđ Test Bank Copyright â 2011 by Saunders, an imprint of Elsevier Inc 5-16 d This study explores what students think about their psychiatric mental health nursing content preceding the content on medical surgical nursing ANS: C An objective is a clear, concise, declarative statement that is expressed in the present tense and usually focuses on one or two variables “Do nursing students ultimately perform better on NCLEX® when they have had the content in psychiatric mental health nursing first or when they have the content in medical surgical nursing first?” is not an objective It is stated as a question An objective is a clear, concise, declarative statement that is expressed in the present tense and usually focuses on one or two variables An objective is a clear, concise, declarative statement (not a question) that is expressed in the present tense and usually focuses on one or two variables The study referenced is not about student’s opinions on psychiatric mental health and medical surgical nursing DIF: Cognitive level: Analysis REF: p 160 30 What statement is true regarding objectives in qualitative studies? a Qualitative studies usually not have an objective statement since the focus in the study shifts as the study progresses In qualitative research, the study objective and hypothesis are the same b Objective statements are long and complex in qualitative studies since they are more difficult and involve many more variables c The variables and concepts in qualitative studies are usually more complex, so the objective statement is broader in focus Qualitative studies usually not have an objective statement since the focus in the study shifts as the study progresses http://getbooksolutions.com d The variables and concepts in qualitative studies are usually more complex, so the objective statement is broader in focus ANS: D The objectives directing qualitative studies are commonly broader in focus and include variables or concepts that are more complex and abstract than those of quantitative studies The statement for this choice is incorrect The objectives directing qualitative studies are commonly broader in focus and include variables or concepts that are more complex and abstract than those of quantitative studies There is not a certainty that an objective statement for qualitative research will itself be more lengthy and complex than one for quantitative research The objectives directing qualitative studies are commonly broader in focus and include variables or concepts that are more complex and abstract than those of quantitative studies A qualitative study does have objectives; they have a slightly different focus than for quantitative studies The objectives directing qualitative studies are commonly broader in focus and include variables or concepts that are more complex and abstract than those of quantitative studies DIF: Cognitive level: Comprehension REF: p 160 Test Bank Copyright © 2011 by Saunders, an imprint of Elsevier Inc 5-17 31 Which of the following would be an appropriate research question for a qualitative study? a How parents decide when to take their child to a physician? b How many visits physicians’ offices receive on Mondays as opposed to Wednesdays? c Should parents take their child to the physician for routine visits? d What is the most common reason for a trip to a physician’s office? ANS: A Exploring the reasoning of parents in making the decision to take their child to the physician is an appropriate research question for a qualitative study This response indicates a quantitative project because of its mention of numerical data This response is phrased as an evaluative question, requiring an ethical analysis This is not a researchable question This response indicates a quantitative project because of its mention of numerical data DIF: Cognitive level: Analysis REF: p 163 32 A researcher uses the following hypothesis in a study: excessive listening to http://getbooksolutions.com alternative music will lead to increased depression in young teenagers Which of the following descriptors can be applied to this hypothesis? a Complex, associative b Complex, negative c Positive, causal d Simple, nondirectional ANS: C The research hypothesis is simple because there are two variables (listening to alternative music and depression), causal because it predicts that excessive listening will lead to depression, and positive because more listening will lead to more depression The hypothesis goes further than predicting a relationship; it says that one variable causes the other The research hypothesis is simple because there are two variables (listening to alternative music and depression), causal because it predicts that excessive listening will lead to depression, and positive because more listening will lead to more depression The hypothesis included only two variables, and the relationship predicted is a positive one The research hypothesis is simple because there are two variables (listening to alternative music and depression), causal because it predicts that excessive listening will lead to depression, and positive because more listening will lead to more depression Although the hypothesis is simple, it is directional The research hypothesis is simple because there are two variables (listening to alternative music and depression), causal because it predicts that excessive listening will lead to depression, and positive because more listening will lead to more depression DIF: Cognitive level: Analysis REF: pp 167, 170, 172 33 A researcher uses the following hypothesis in a study: “Excessive listening to alternative music will lead to increased depression in young teenagers.” Which of the following dependent variables would need to be defined operationally in the research study?

a Complex b Continuous c Dependent d Extraneous ANS: B Although “listening” could be a discrete variable, depending on how it is measured, all other choices can be eliminated as wrong Excessive listening is the independent variable It is not complex because it is only one concept Listening is a central or integral concept in the study and therefore not extraneous Because “listening” is more than likely measured by time, a continuous variable, this answer is correct There are only two variables in the study, so it is a simple hypothesis, and complex does not describe variables used, but the number of variables noted in the hypothesis The dependent variable in this study is degree of depression, which is dependent on or affected by the listening to alternative music The amount of listening to alternative music is an integral part of the study, so it is not an extraneous variable DIF: Cognitive level: Application REF: p 176 Test Bank Copyright © 2011 by Saunders, an imprint of Elsevier Inc http://getbooksolutions.com 5-19 35 A researcher uses the following hypothesis in a study: “Excessive listening to alternative music will lead to increased depression in young teenagers.” Which of the following statements is an acceptable operational definition of “excessive listening”? Excessive listening is defined as: a listening to alternative music more than the average number of hours young teenagers listen to that type of music b that number of hours over which parents begin to place limitations on listening time c the number of hours a subject spends listening to alternative music d the number of hours the subjects listen to alternative music A mean of these hours will be calculated, and “excessive” will be anything over the mean ANS: C An operational definition is derived from a set of procedures or progressive acts that a researcher performs to measure a variable Although the hypothesis predicts that excessive listeners will have more likelihood of depression, the variable itself is how many hours of time are spent listening to the music The subjects who listen to the highest number of hours are the ones most likely to exhibit depression An operational definition is developed so that a variable can be measured or manipulated in a concrete situation This definition does not tell the reader where the information needed to use it came from An operational definition is derived from a set of procedures or progressive acts that a researcher performs to measure a variable Although the hypothesis predicts that excessive listeners will have more likelihood of depression, the variable itself is how many hours of time are spent listening to the music The subjects who listen to the highest number of hours are the ones most likely to exhibit depression An operational definition is developed so that a variable can be measured or manipulated in a concrete situation There is no mention of parental opinion in the hypothesis This definition introduces an additional variable, so it is not correct An operational definition is derived from a set of procedures or progressive acts that a researcher performs to measure a variable Although the hypothesis predicts that excessive listeners will have more likelihood of depression, the variable itself is how many hours of time are spent listening to the music The subjects who listen to the highest number of hours are the ones most likely to exhibit depression An operational definition is developed so that a variable can be measured or manipulated in a concrete situation http://getbooksolutions.com The definition needs to be established before the study begins Having the subjects within the study define the variables of the study is not useful An operational definition is derived from a set of procedures or progressive acts that a researcher performs to measure a variable Although the hypothesis predicts that excessive listeners will have more likelihood of depression, the variable itself is how many hours of time are spent listening to the music The subjects who listen to the highest number of hours are the ones most likely to exhibit depression An operational definition is developed so that a variable can be measured or manipulated in a concrete situation DIF: Cognitive level: Analysis REF: p 178 Test Bank Copyright © 2011 by Saunders, an imprint of Elsevier Inc 5-20 36 Demographic variables are often used to indicate which of the following? a Extraneous variables b Population parameters c Research hypothesis d Sample characteristics ANS: D Demographic variables are characteristics or attributes of subjects that are collected to describe the sample They are often used to provide a picture of the sample and are called sample characteristics Extraneous variables are not necessarily demographic in nature Demographic variables are characteristics or attributes of subjects that are collected to describe the sample They are often used to provide a picture of the sample and are called sample characteristics The population parameters are connected with the entire population, not just the sample Demographic variables are characteristics or attributes of subjects that are collected to describe the sample They are often used to provide a picture of the sample and are called sample characteristics The research hypothesis indicates the expected relationship between the variables Demographic variables are characteristics or attributes of subjects that are collected to describe the sample They are often used to provide a picture of the sample and are called sample characteristics DIF: Cognitive level: Application REF: p 182 37 Which of the following is an acceptable operational definition according to the requirements of how to operationalize a variable? Depression will be operationalized as: a the subject’s score on the State-Trait Anxiety scale b the total number of times a subject uses words, such as empty, blue, sad, or http://getbooksolutions.com depressed c a below-normal physical appearance d a self-defining concept, based on the individual’s definition of depression ANS: A Although the study will receive much criticism as to its validity, the researcher has operationalized the variable in a correct manner An operational definition is derived from a set of procedures or progressive acts that a researcher performs to receive sensory impressions that indicate the existence or degree of existence of a variable An operational definition is developed so that a variable can be measured or manipulated in a concrete situation They must be independent of time or setting so that variables can be investigated at different times and in different settings An operational definition is derived from a set of procedures or progressive acts that a researcher performs to receive sensory impressions that indicate the existence or degree of existence of a variable An operational definition is developed so that a variable can be measured or manipulated in a concrete situation They must be independent of time or setting so that variables can be investigated at different times and in different settings Test Bank Copyright © 2011 by Saunders, an imprint of Elsevier Inc 5-21 There is no way to determine what the researcher will actually take into account for this definition An operational definition is derived from a set of procedures or progressive acts that a researcher performs to receive sensory impressions that indicate the existence or degree of existence of a variable An operational definition is developed so that a variable can be measured or manipulated in a concrete situation They must be independent of time or setting so that variables can be investigated at different times and in different settings An operational definition is derived from a set of procedures or progressive acts that a researcher performs to receive sensory impressions that indicate the existence or degree of existence of a variable An operational definition is developed so that a variable can be measured or manipulated in a concrete situation They must be independent of time or setting so that variables can be investigated at different times and in different settings DIF: Cognitive level: Analysis REF: p 178 38 Which of the following is a correct statement regarding operational and conceptual definitions in qualitative studies? a Developing conceptual definitions are usually the reason for a qualitative study b Qualitative studies not use conceptual or operational definitions c The conceptual and operational definitions should be consistent in a qualitative http://getbooksolutions.com study d The operational and conceptual definitions are often first found in the summary and conclusions section in a qualitative research report ANS: C An operational definition is used in qualitative research However, it can be one of the parts of data collection and is not as concrete as in quantitative research The main point in critiquing the characteristics of the operational and conceptual definitions within a qualitative research study is that the two are consistent A conceptual definition is not the main reason for conducting all qualitative research, although it may be part of the process of the study An operational definition is used in qualitative research Both operational and conceptual definitions can be part of data collection and are not as concrete as in quantitative research An operational definition is used in qualitative research Both operational and conceptual definitions can be parts of data collection and are not as concrete as in quantitative research The conceptual and operational definitions can be found in different places in a qualitative study, but it is not likely that they first appear in the last section of the report An operational definition is used in qualitative research Both operational and conceptual definitions can be part of data collection and are not as concrete as in quantitative research DIF: Cognitive level: Application REF: p 178 39 What is a difference between correlational and quasi-experimental research? a Correlational research is less significant than quasi-experimental research b The hypotheses in correlational research are more complex Test Bank Copyright © 2011 by Saunders, an imprint of Elsevier Inc 5-22 c The researcher wants to predict what will happen in quasi-experimental research d There are many more variables in quasi-experimental research ANS: C Quasi-experimental designs seek to discover whether an independent variable causes an effect on a dependent one Correlational research establishes an association between and among variables, and the number of variables is based on the study purpose and problem, not what kind of study it is There can be significant findings in each type of study The complexity of a hypothesis is determined by how many variables are involved, not the kind of study There can be significant findings in each type of study All types of studies are needed to http://getbooksolutions.com expand nursing knowledge and science The complexity of a hypothesis is determined by the number of variables are involved, not the kind of study The complexity of a hypothesis is determined by the number of variables are involved, not the kind of study DIF: Cognitive level: Comprehension REF: pp 150-151 40 A researcher wants to investigate the possibility that diabetic patients who are allowed to cook their own meals will adhere to dietary restrictions better than patients who not What is the dependent variable? a Adherence to dietary restrictions b Diabetes c Dietary restrictions d Meal cooking ANS: A It is hypothesized that cooking one’s meals will lead to better compliance with dietary restrictions Self-cooking influences compliance Adherence is what the researcher wants to influence and is the independent variable The study population appears to be patients with diabetes, so diabetes is constant and not a variable It is hypothesized that cooking one’s meals will lead to better compliance with dietary restrictions Self-cooking influences compliance Adherence is what the researcher wants to influence and is the independent variable Actually, all patients in the population have dietary restrictions, so this is not a variable It is hypothesized that cooking one’s meals will lead to better compliance with dietary restrictions Self-cooking influences compliance Adherence is what the researcher wants to influence and is the independent variable Meal cooking is the independent variable It is hypothesized that cooking one’s meals will lead to better compliance with dietary restrictions Self-cooking influences compliance Adherence is what the researcher wants to influence and is the independent variable DIF: Cognitive level: Application REF: p 176
