` l ` ! Provide a ` 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`!
conducted to describe CDS scores
` l` ! for study participants (see Table `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
`l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!

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.

8. What frequency and percent of cardiac patients in this study were not
`l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!
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
`l`! ` l ` ! `l`! ` l ` ! l̀`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`! `l`!
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
`l`! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! `l`! ` l ` ! `l`!
have also subtracte d the 14% of patients treated with antidepressants from
` l ` ! `l`! `l`! `l`! `l`! `l`! `l`! `l`! ` l`! `l`! ` l` ! `l`! ` l`! `l`! `l`! `l`! ` l` ! `l`! `l`! `l`! ` l` ! `l`!
, `l`! 100% and obtained the 86% who were not treated with an antidepressant.

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?
`l `! `l`! `l`! `l`! `l`! `l`! `l ` ! `l`! `l`! `l`! `l`! `l`! ` l ` ! `l`! `l` ! `l`! `l`! `l`! `l`! `l`! ` l ` !
Answer: Ha et al. (2018) stated,
` l` ! ―The 6-
` l ` ! `l`! `l`! ` l ` ! ` l ` ! ` l ` ! ` l ` !
min walk test (6MWT) is
` l ` ! a measure of the
` l ` ! submaximal, steady- ` l ` ! `l`! ` l ` ! `l`! `l`! `l`! `l`! ` l ` ! ` l ` ! `l`! ` l` !
state functional capacity‖ of cardiac patients. This test would be a quick, easy way
` l` ! `l`! ` l` ! ` l` ! ` l`! ` l` ! ` l` ! `l`! `l`! `l`! ` l` ! ` l`! ` l` !
to determine a cardiac patient’s functional status in a clinical
`l`! `l`! `l`! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! `l`!
setting.
` l ` ! This functionalstatus score could be used to determine the
`l`! ` l ` ! `l`! ` l ` ! l̀`! ` l` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` ! ` l ` !
treatment plan to promote or maintain
