The neuroscience nursing unit has developed a set of step-by-step directions of what should occur if
Y1 JY1 JY 1 JY1 JY1 JY1 JY1 JY1 JY 1 JY1 JY1 JY 1 JY1 JY 1 JY 1 JY 1




a nursing assessment reveals the client may be exhibiting clinical manifestations of a
JY 1 JY 1 JY1 JY 1 JY 1 JY1 JY 1 JY 1 JY 1 JY 1 JY1 JY 1 JY 1




cerebrovascular accident (CVA). Which statement about clinical practice guidelines are accurate? JY1 JY 1 JY 1 JY 1 JY1 JY1 JY 1 JY1 JY 1 JY1 JY 1




Select all that apply. JY1 JY1 JY 1




Selected C.
Answers: When developing a CVA set of step-by-step directions, the nursing unit should ask for
JY 1 JY 1 JY 1 JY 1 JY1 J Y1 JY 1 JY1 JY1 JY 1 JY 1 JY1 JY1 JY1 JY 1




assistance from experts in the neuroscience field. The potential users of the guidelines should pilot
JY 1 JY 1 JY 1 JY 1 JY1 JY 1 JY1 JY 1 JY 1 JY1 JY 1 JY 1 JY 1 JY 1 JY1




test it for further feedback.
JY1 JY1 JY1 JY1




D.
A meta-analysis could be utilized to combine evidence from different studies to produce a more
JY1 JY 1 JY 1 JY 1 JY1 JY 1 JY 1 JY1 JY 1 JY1 JY1 JY 1 JY 1 JY 1 JY 1




accurate diagnostic method. JY1 JY1




E.
The development of evidence-based practice guidelines require a research review from different
JY1 JY1 JY 1 JY 1 JY 1 JY 1 JY 1 JY 1 JY1 J Y1 JY 1 JY1




studies to develop the most accurate diagnostic method to implement.
JY1 JY 1 JY1 JY 1 JY1 JY 1 JY1 JY1 JY 1




Response Rationale: Clinical practice guidelines are systematically JY1 JY1 JY 1 JY1 JY1




Feedback: developed and intended to inform practitioners in making decisions about health care JY1 JY 1 JY 1 JY1 JY 1 JY1 JY 1 JY1 JY 1 J Y1 JY 1 JY 1




for CVA clients. They should be developed using research and review by experts in the clinical
JY 1 JY1 JY 1 JY 1 JY 1 JY 1 JY 1 JY1 JY1 JY 1 JY 1 JY 1 JY 1 JY 1 JY 1 JY 1




content. Potential users should also participate and provide feedback prior to implementation. The
JY1 JY 1 J Y1 JY1 J Y1 JY1 JY 1 JY 1 JY 1 JY1 JY 1 JY1 JY1




purpose of the guidelines is to review EBP articles and develop new practice guidelines rather that
JY1 JY1 JY 1 JY 1 JY 1 JY 1 JY1 J Y1 JY1 JY 1 JY1 JY1 JY 1 JY 1 JY 1 JY 1




continuing practicing primarily on "how it has always been done before." Once developed, the
JY1 JY1 J Y1 JY 1 JY1 J Y1 JY 1 JY 1 JY 1 JY 1 JY 1 JY 1 JY1 JY 1




guidelines must be continually reviewed and changed to keep pace with new research findings. A
JY1 JY1 JY1 JY1 JY 1 JY1 JY 1 J Y1 JY 1 JY 1 JY 1 JY 1 JY1 JY1 JY 1




meta-analysis could be utilized to combine evidence from different studies to produce a more JY1 JY 1 JY1 JY 1 JY1 JY 1 JY1 JY1 JY1 JY1 JY 1 J Y1 JY 1 JY 1




accurate diagnostic method or the effects of an intervention method.

Question 2 JY1




The nurse is questioning the validity of oxygen saturation readings from the new oximeters on the
JY1 JY 1 JY 1 JY1 JY 1 JY1 JY 1 JY1 JY1 J Y1 J Y1 JY 1 JY 1 JY1 JY 1 JY1




unit. Which action should the nurse take to best determine if the results from the oximeter are valid?
JY1 JY1 JY 1 JY 1 JY1 JY 1 JY 1 J Y1 JY1 JY1 JY 1 JY1 JY 1 JY 1 JY1 JY1 JY 1




Selected D.
Answer: Compare clients' results to measurements taken using arterial blood gas analyses.
JY1 JY 1 JY 1 JY 1 JY 1 JY1 JY1 JY 1 JY1 JY1




Response Rationale: Validity refers to the extent to which a JY1 JY 1 JY 1 JY1 JY1 JY1 JY 1 JY1




Feedback: measurement tool measures what it is intended to measure. JY1 J Y1 JY 1 JY1 JY1 JY1 JY 1 JY 1




The best way to confirm validity is to compare the measurement against those from another test that
JY1 JY 1 J Y1 JY 1 JY 1 JY1 JY1 JY 1 JY1 JY 1 JY 1 JY1 JY 1 JY 1 JY1 JY1 JY1




measures the same data. Oxygen saturation levels and PaO 2 are both
JY1 JY 1 JY 1 JY1 JY1 JY1 JY 1 JY1 J Y1 J Y1 JY 1




reported on arterial blood gas (ABG) results. The results from any client who had an ABG done
JY1 JY 1 JY 1 JY 1 JY 1 JY1 JY 1 JY1 JY 1 JY 1 JY1 J Y1 JY 1 JY1 JY1 JY1 JY 1




concurrent with an oxygen saturation measurement with the new oximeter could be compared for
JY1 JY 1 JY 1 JY 1 JY 1 JY1 JY1 JY 1 JY 1 J Y1 JY1 JY1 JY1 JY 1




discrepancy. Repeating the test with the same device would provide information about reliability.
JY1 JY 1 JY1 JY 1 JY 1 JY1 JY 1 JY1 JY 1 J Y1 JY1 JY1 JY 1




Reviewing the literature may provide the nurse with the company's interpretation of the validity of
JY 1 JY 1 JY1 JY1 JY1 JY 1 JY1 JY 1 JY 1 JY 1 JY1 JY1 JY 1 JY1 JY 1




the oximeter brand, but this does not guarantee perfect functioning of the unit in question. If the
JY1 JY1 JY1 JY 1 JY1 JY 1 JY 1 JY1 JY1 JY1 JY1 JY 1 JY1 JY 1 JY1 JY 1 JY1




results are inaccurate, comparing these inaccurate results to one another will not help determine
JY1 JY 1 JY 1 JY 1 JY1 JY1 JY1 JY 1 JY 1 JY1 JY 1 JY 1 JY1 JY1




validity of the measurement.

, Question 3 JY 1




Anurse researcher is interested in the natural history of a disease being studied. What should the nurse
JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 J Y1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




focus on to best understand the condition's natural history?
JY1 JY 1 JY1 JY1 JY1 JY1 JY1 JY1




Selected JY1 A.
Answer: Focusing on clients who did not receive treatment for the JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




condition

Response JY1 Rationale: The natural history of a disease refers to the JY1 JY1 JY1 J Y1 JY1 JY1 JY1 JY 1 JY1 JY1




Feedback: progression and projected outcome of the disease without JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




medical intervention. For this reason, following clients who JY1 JY1 JY1 JY 1 JY1 JY1 JY1 JY1




have had any level of treatment will be less valuable at
JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




establishing natural history than focusing on only those who JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




have had no treatment. Client experience with the condition
JY1 JY1 JY1 JY 1 JY1 JY1 JY1 JY 1 JY1




will not inform how the disease progresses from a pathogenesis
JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




perspective.

A nurse practitioner is working in a crowded neighborhood where the
JY1 JY1 JY1 JY1 JY 1 JY1 JY1 JY 1 J Y 1 JY1 JY1




population is primarily immigrants from China. The nurse has designed a JY1 JY1 JY1 JY1 JY 1 JY1 JY1 JY1 JY1 JY1 JY1




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

Response Rationale: In this cohort study, a group of people who were JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




Feedback: born at approximately the same time or share some JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




characteristics of interest is the focus of the research. This study JY1 JY1 JY 1 JY1 JY1 JY1 JY 1 JY 1 JY1 JY1 J Y1




does not possess the characteristics of a case–control or cross- JY1 JY1 JY1 JY1 JY 1 JY1 JY1 JY1 JY1




sectional study. Epidemiologic study is not an existing J Y 1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




methodology.

The clinical educator of a hospital medical unit has the mandate of
JY1 JY1 JY 1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




establishing evidence-based practice guidelines for the nursing care on the JY1 JY1 JY 1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




unit. Which statement most accurately captures a guiding principle of the
JY1 JY 1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




nurse's task? JY1




Selected JY1 A.
Answer: The guidelines will combine individual expertise with external
JY1 JY1 JY1 JY1 JY1 JY1 JY1 JY1




systematic evidence. JY1
