Question 1 1 ou of 1 points
J




The neuroscience nursing unit has developed a set of step-by-step directions of what should occur if a
J J J J J J J J J J J J J J J J




nursing assessment reveals the client may be exhibiting clinical manifestations of a cerebrovascular
J J J J J J J J J J J J J




accident (CVA). Which statement about clinical practice guidelines are accurate? Select all that apply.
J J J J J J J J J J J J J




Selected C.
Answers: When developing a CVA set of step-by-step directions, the nursing unit should ask for
J J J J J J J J J J J J J J J




assistance from experts in the neuroscience field. The potential users of the guidelines should pilot test
J J J J J J J J J J J J J J J J




it for further feedback.
J J J




D.
A meta-analysis could be utilized to combine evidence from different studies to produce a more
J J J J J J J J J J J J J J J




accurate diagnostic method. J J




E.
The development of evidence-based practice guidelines require a research review from different
J J J J J J J J J J J J




studies to develop the most accurate diagnostic method to implement.
J J J J J J J J J




Response Rationale: Clinical practice guidelines are systematically J J J J J




Feedback: developed and intended to inform practitioners in making decisions about health care for
J J J J J J J J J J J J J




CVA clients. They should be developed using research and review by experts in the clinical content.
J J J J J J J J J J J J J J J J




Potential users should also participate and provide feedback prior to implementation. The purpose of
J J J J J J J J J J J J J J




the guidelines is to review EBP articles and develop new practice guidelines rather that continuing
J J J J J J J J J J J J J J J




practicing primarily on "how it has always been done before." Once developed, the guidelines must be
J J J J J J J J J J J J J J J J




continually reviewed and changed to keep pace with new research findings. A meta-analysis could be
J J J J J J J J J J J J J J J




utilized to combine evidence from different studies to produce a more accurate diagnostic method or
J J J J J J J J J J J J J J J




the effects of an intervention method.

Question 2 J




The nurse is questioning the validity of oxygen saturation readings from the new oximeters on the unit.
J J J J J J J J J J J J J J J J J




Which action should the nurse take to best determine if the results from the oximeter are valid?
J J J J J J J J J J J J J J J J




Selected D.
Answer: Compare clients' results to measurements taken using arterial blood gas analyses.
J J J J J J J J J J




Response Rationale: Validity refers to the extent to which a
J J J J J J J J




Feedback: measurement tool measures what it is intended to measure. J J J J J J J J




The best way to confirm validity is to compare the measurement against those from another test that
J J J J J J J J J J J J J J J J J




measures the same data. Oxygen saturation levels and PaO 2 are both
J J J J J J J J J J J




reported on arterial blood gas (ABG) results. The results from any client who had an ABG done
J J J J J J J J J J J J J J J J J




concurrent with an oxygen saturation measurement with the new oximeter could be compared for
J J J J J J J J J J J J J J




discrepancy. Repeating the test with the same device would provide information about reliability.
J J J J J J J J J J J J J




Reviewing the literature may provide the nurse with the company's interpretation of the validity of the
J J J J J J J J J J J J J J J J




oximeter brand, but this does not guarantee perfect functioning of the unit in question. If the results are
J J J J J J J J J J J J J J J J J J




inaccurate, comparing these inaccurate results to one another will not help determine validity of the
J J J J J J J J J J J J J J J




measurement.

, Question 3 J




Anurse researcher is interested in the natural history of a disease being studied. What should the nurse
J J J J J J J J J J J J J J J J J J




focus on to best understand the condition's natural history?
J J J J J J J J




Selected J A.
Answer: Focusing on clients who did not receive treatment for the J J J J J J J J J J




condition

Response J Rationale: The natural history of a disease refers to the J J J J J J J J J J




Feedback: progression and projected outcome of the disease without J J J J J J J J




medical intervention. For this reason, following clients who have
J J J J J J J J J




had any level of treatment will be less valuable at establishing
J J J J J J J J J J J




natural history than focusing on only those who have had no
J J J J J J J J J J J




treatment. Client experience with the condition will not inform J J J J J J J J J




how the disease progresses from a pathogenesis perspective.

A nurse practitioner is working in a crowded neighborhood where the
J J J J J J J J J J J




population is primarily immigrants from China. The nurse has designed a J J J J J J J J J J J




research study to follow children from kindergarten to the age of 25. She is
J J J J J J J J J J J J J J




going to be looking at their diet, successful progression in school, health
J J J J J J J J J J J J




practices, and development of disease, to name a few items. This type of
J J J J J J J J J J J J J




research is known as: J J J




Selected Answer: J
B. Cohort study J
J




Response J Rationale: In this cohort study, a group of people who were born at J J J J J J J J J J J J J




Feedback: approximately the same time or share some characteristics of J J J J J J J J J




interest is the focus of the research. This study does not possess
J J J J J J J J J J J J




the characteristics of a case–control or cross-sectional study.
J J J J J J J J




Epidemiologic study is not an existing methodology. J J J J J J

The clinical educator of a hospital medical unit has the mandate of establishing
J J J J J J J J J J J J J




evidence-based practice guidelines for the nursing care on the unit. Which J J J J J J J J J J J




statement most accurately captures a guiding principle of the nurse's task?
J J J J J J J J J J




Selected J A.
Answer: The guidelines will combine individual expertise with external
J J J J J J J J




systematic evidence. J
