- What is the total sample size of COPD patients included in this study?
Total sample size 91: Moderate Airflow Limitation (42), Severe Airflow Limitation (49).
- What percentage of the total sample is retired? What percentage of the total sample is on sick leave?
61% of the total sample is retired and 15% of the total sample on sick leave
- Is there a significant difference between the moderate and severe airflow limitation groups regarding the use of short-acting β2-agonists? Provide a rationale for your answer.
Yes, only 31% of the moderate airflow limitation group used short-acting β 2 -agonists while 65% of the severe airflow limitation group also used short-acting β 2 -agonists.
- What were the four most common psychological symptoms reported by this sample of patients with COPD? Identify the psychological symptoms and the percentages of the total sample experiencing each symptom.
The four most common psychological symptoms were difficulty sleeping, worrying, feeling irritable and feeling sad. Difficulty sleeping (52%), worrying (33%), feeling irritable (28%) and feeling sad (22%).
- Is there a significant difference between the moderate and severe airflow limitation groups regarding pack years of smoking? Provide a rationale for your answer.
No significant difference between two groups. Both groups have been smoking long enough to cause a significant injury to the lungs. There is no difference between moderate and severe groups regarding the pack year of smoking because the p value is 0.177 (less than 5%). Moderate 29.1 and Severe 34.0

- State the null hypothesis for the nursing outcome family participation in professional care.
The null hypothesis for the nursing outcome family participation in professional care is there is no change in the nursing outcome family participation in professional care for patients with heart failure receiving four home visits and telephone calls over a 6-month period.
.
- Was there a statistically significant difference in family participation in professional care from HV1 to HV4? (Was the null hypothesis accepted or rejected?) Provide a rationale for your answer.
Based on the information provided in the study, p = 0.101 for family participation in professional care, so there was not a statistically significant difference from HV1 to HV4. Since there is no significance (p is not less than or equal to 0.05), the null hypothesis would be accepted.
- State the null hypothesis for the nursing outcome activity tolerance.
The null hypothesis for the nursing outcome activity tolerance is: there is no change in the nursing outcome activity tolerance for patients with heart failure (heart failure) receiving HVs and telephone calls over a 6 month period.
- Was there a significant difference in activity tolerance from the first home visit (HV1) to the fourth home visit (HV4)? (Was the null hypothesis accepted or rejected?) Provide a rationale for your answer.
Yes, based on the information that was provided in the reading, there was a significant difference in activity tolerance from tHV1 to HV4, given that p = 0.004. The null hypothesis is rejected since alpha (a) was set at 0.05 and the p values are less than a. The results are statistically significant because the p values are less than the set a value of 0.05.
- What implications for practice do you note from these study results?
The implications for practice that I note from these study results are that fluid balance and family participation in professional care showed the least amount of improvement. There are both areas that need to be improved for heart failure patients, so I will recognize that in my practice and try to find ways to improve the outcomes.
