rationale
` l ` ! for your answer. Answer: The CDS score is at the interval ` l ` ! ` l ` ! ` l ` ! `l`! `l`! `l`! ` l` ! `l`! ` l` ! `l`! ` l` ! `l`! ` l`! `l`! `l`! `l`! `l`! `l`!

CDS scores
`l`! for the cardiac patients in this study? Provide a rationale for
`l`! `l`! l̀`! ` l ` ! `l`! ` l` ! `l ` ! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l` ! `l`!



your answer. Answer: Parametric statistics, such as mean and SD, were
`l ` ! `l`! `l`! `l`! `l`! ` l`! ` l` ! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!

1). CDS
` l ` ! scores are interval- ` l ` ! ` l ` ! ` l ` ! ` l ` !



level data as indicated in Questions 5, so parametric statistics are appropriate for

7. Is the prevalence of depression linked to the NYHA class? Discuss the clinical
`l`! `l`! `l` ! `l`! `l`! `l`! `l`! ` l` ! `l`! `l` ! `l` ! `l`!



importance of this result.
`l`! l̀`! `l`! `l`! `l`!



Answer: The study narrative indicated that the prevalence of depression ` l` ! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! ` l`! `l`! `l`! `l`! `l`! `l`! ` l` ! `l`!



increased with the greater
` l` ! NYHA class. In NYHA class III, 64% of`l`! `l`! `l`! `l`! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` !



the subjects were
` l ` ! depressed, whereas 11%
` l ` ! of the subjects were ` l ` ! ` l ` ! ` l ` ! l̀`! ` l ` ! ` l ` ! ` l ` ! ` l`! ` l ` !



depressed in
` l ` ! NYHA class I. Thus, as the NYHA class ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` !



increased,
` l ` ! the number of sub- l̀`! ` l ` ! ` l ` ! ` l ` ! ` l ` !



jects with depression increased. This is an expected finding because as the
`l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!



NYHA classincreases, cardiac patients have more severe physical symptoms,
`l`! `l`! l̀`! ` l ` ! `l`! ` l ` ! `l `! `l`! ` l ` ! `l` !



which usually result in emotional distress, such as depression. Nurses need to
` l ` ! ` l ` ! `l` ! `l`! `l`! ` l` ! `l`! `l`! `l`! `l` ! ` l` ! `l`!



actively assess cardiac patients for depression,
`l`! especially those in
`l`! higher `l`! `l` ! `l`! `l`! ` l ` ! ` l ` ! ` l ` ! ` l ` !



NYHA
` l ` ! classes, so they might be diagnosed and treated as ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! `l`! `l`! `l`! `l`! `l`!



needed.

being trea ted with an antidepressant? Show your calculations and round your
`l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!



answer to the nearest whole percent (%).
`l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!



Answer: A total of 106 cardiac patients participated in this
` l ` ! study. ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! `l`! ` l ` ! `l`! ` l ` !



The sample
`l`! ` l ` ! included 15 patients who were receiving an

antidepressant (see Table 1). The number
`l`! of cardiac patients not `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! l̀`! ` l ` ! ` l ` ! ` l` ! ` l ` !



treated for depression was 91 (106 –
` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` !



15 = 91). The group percent is calculated by
` l ` ! the following
` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! `l`! ` l` ! `l`! ` l ` ! `l`! ` l ` ! `l`!



formula:
` l ` ! (group frequency ÷ total sample size) × 100%. For `l`! ` l ` ! `l`! ` l ` ! l̀`! ` l ` ! ` l ` ! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! ` l ` ! `l`! ` l ` ! `l`!



this study, (91
` l ` ! patients ÷ 106 sample
`l`! size) × 100% = 0.858
` l ` ! `l`! `l`! `l`! ` l ` ! `l`! ` l ` ! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! l̀`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!



× 100% = 85.8% = 86%. The final answer is rounded to the
`l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! l̀`! `l`!



nearest
` l ` ! whole percent as directed in the question. You could

t. What was the purpose of the 5-
` l ` ! `l`! `l `! `l`! `l`! `l`! ` l` ! `l`! ` l `! `l`! `l `! `l`! `l`!



minute walk test (5MWT)? Would the 5MWT be useful in clinical practice?

Answer: Ha et al. (2018) stated,
` l` ! ―The 6-
` l ` ! `l`! `l`! ` l ` ! ` l ` ! ` l ` ! ` l ` !



min walk test (6MWT) is

setting.
` l ` ! This functionalstatus score could be used to determine the
