distress, and dry mouth. The intervention group (62) had more participants than the control group (42). Patient’s difference in perception of all three categories on the NRS. The gap difference in the number between the intervention and control groups. c) What was the final sample sizeand what was the acceptance rate? The final sample size was 103 patients. The acceptancerate was 61%. (134/219= 0.611 X 100% = 61%d) Was a power analysis conducted? If so, describe it here.Yes, a priori power analysis was done and determined that 66 patients would be needed for each group. (αof.05, a power of 0.80 and an effect size of 0.35)e) Describe the inclusion andexclusion sample criteria.Inclusion sample criteria included patients >18 yrs old,that spoke English and could provide informed consent. ICU stay had to be 12 hours or more, had to have a specific score on the RAAS scale, patient also had to have a baseline thirst intensity and distress scoreof 3 or greater. Exclusion sample criteria included patient could not have a history of dementia nor oral lesions in the mouth or lips or recent oral surgery that would hinder the interventions. f) Calculate the refusal rate.Refusal rate= (85 patients declined participation/ 219 eligible patients = 38.81g) Calculate the attrition rate.Attrition rate = (31 patient lost due to transfer from unit/ 134 [sample size] = 23% h) Is the sampling method going to produce a sample that is representative of the study population? Explain your answer.Yes, the study population was strictly ICU patients andthe convenience sample for this research study consisted of only ICU patients and no other populations. i) Briefly discuss the institutional review boardapprovaland informed consentobtained for this study. IRB plays an important role in research because it determines if the research is truly ethical for one and whether there is potential risks. The researchers submitted this through their appropriate IRB committee for approval and proper consent was obtained from patients who participated j) Briefly describe the setting andindicate whether it wasappropriatefor conducting this study.The setting was in two ICU units which were appropriate for the study since the study was specific to ICU patients only. Question #10: Measurement Methods: (For help with these questions, refer to chapters16, 17, 18)a) List and briefly describe the measures / instruments / tools used in the study.NRS (numeric rating scale) was used and paper copy of NRS for those who had mechanical ventilation. The measures included 0 for no thirst/distress/dry mouth to 10 worst thirst/distress/dry mouth. Nurses used a tool to collect data that was designed by the researcher. TheRAAS was used to meet eligibility criteria. b) Who administers each measurement / instrument / tool?Trained nurses were responsible for data collection to allow for fewer errors.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
