data (Grove & Gray, 2019; Waltz et al., 2017).
! ! ! ! ! ! ! ! !

1. What level of measurement is the CDS score? Provide a rationale for your
! ! ! ! ! ! ! ! ! ! ! !

answer. Answer: The CDS score is at the interval level of measurement. The CDS is a 26-
! ! ! !! !! !! !! !! !! !! !! !! !! !! !! !! !!

item Likert scale developed to measure depression in cardiac patients. Study participants
! !! !! !! !! !! !! !! !! !! !! !! !

rated their symp-
! ! !

toms on a scale of 1 to 7, with higher numbers indicating increased severity in
! ! ! ! ! ! ! ! ! ! ! ! ! !

thedepression symptoms. The total scores for each subject obtained from this multi-
! ! ! ! ! ! ! ! ! ! ! ! !

item scale are considered to be at the interval level of measurement (Gray et al., 2017
! !! !! !! !! !! !! !! !! !! !! !! !! !! !!

; Waltz et al., 2017).
! !! !! !!

5. Were nonparametric or parametric analysis techniques used to analyze the CDS scores
! ! ! ! ! ! !! !! !! !! !! !! !

for the cardiac patients in this study? Provide a rationale for your answer. Answer:
! ! ! ! ! ! ! ! ! ! !! !! !! !

Parametric statistics, such as mean and SD, were conducted to describe CDS scores for
! ! ! ! ! ! !! !! !! !! !! !! !

study participants (see Table 1). CDS scores are interval-
! ! ! ! ! ! ! ! !

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

data (Gray et al., 2017; Kim & Mallory, 2017).
! ! ! ! ! ! ! ! !

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

of this result.
! ! !

Answer: The study narrative indicated that the prevalence of depression increased with the
! ! !! !! !! !! !! !! !! !! !! !

greater NYHA class. In NYHA class III, 64% of the subjects were depressed,
! ! ! ! ! ! ! ! ! ! ! ! !

whereas 11% of the subjects were depressed in NYHA class I. Thus, as the NYHA
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

class increased, the number of sub-
! ! ! ! ! ! !

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

classincreases, cardiac patients have more severe physical symptoms, which usually result
! ! ! ! ! ! ! ! ! ! ! !

in emotional distress, such as depression. Nurses need to actively assess cardiac patients for
! ! ! ! ! ! ! ! ! ! ! ! ! !

depression, especially those in higher NYHA classes, so they might be diagnosed
! ! ! ! ! ! ! ! ! ! ! ! !!

and treated as needed.
! ! ! !

8. What frequency and percent of cardiac patients in this study were not being trea ted
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

with an antidepressant? Show your calculations and round your answer to the nearest
! ! ! ! ! ! ! ! ! ! ! ! ! !

whole percent (%).
! ! !

Answer: A total of 106 cardiac patients participated in this study. The sample ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

included
! 15 patients who were receiving an antidepressant (see Table 1). The
! !! !! !! !! !!! !!! !!! !!! !!! !!! !!

number of cardiac patients not treated for depression was 91 (106 –
! ! ! ! ! ! ! ! ! ! ! ! !

15 = 91). The group percent is calculated by the following formula: (group
! ! ! ! ! ! ! !! ! ! ! ! ! ! ! ! !

frequency ÷ total sample size) × 100%. For this study, (91 patients ÷ 106 sample
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !! ! ! ! ! ! ! !

size) × 100% = 0.858 × 100% = 85.8% = 86%. The final answer is rounded to the
! ! ! !! ! !! ! !! ! !!! ! !!! ! !!! !!! !! !!! !!! !!! !!! ! !

nearest whole percent as directed in the question. You could have also subtracte d the
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !! !! ! ! !

14% of patients treated with antidepressants from 100% and obtained the 86% who were not
! !! !! !! !! !! !! ! ! !! !! !! !! ! ! !

treated with an antidepressant.
! ! ! !

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

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

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

min walk test (6MWT) is a measure of the submaximal, steady-
! ! ! ! ! !! !! ! ! !!

state functional capacity‖ of cardiac patients. This test would be a quick, easy way to
! ! ! ! ! ! ! ! ! ! ! ! ! !!

determine a cardiac patient’s functional status in a clinical setting. This
! ! ! ! ! ! ! ! ! ! ! ! ! !

, ! functionalstatus score could be used to determine the treatment plan to promote or
