1. In Table 1, identify the level of measurement for the current therapy variable. Provide a

rationale for your answer. ci ci ci


Answer: The current therapy variable was measured at the nominal level. These drug categorie

swere probably developed to be exhaustive for this study and included the categories of drugs th

esubjects were receiving. However, the categories are not exclusive, since patients are usually o

n more than one category of these drugs to manage their health problems. The current therapies
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


are not measured at the ordinal level because they cannot be rank ordered, since no drug category c

2. What is the mode for the current therapy variable in this study? Provide a rationale
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


foryour answer. ic ci


Answer: The mode for current therapy was β blocker. A total of 100 (94%) of the cardiac patients
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


were receiving this category of drug, which was the most common prescribed drug fo

3. What statistics were conducted to describe the BMI of the cardiac patients in this sample
ci ci ci ci ci ci ci ci ci ci ci ci ci ci


?Discuss whether these analysis techniques were appropriate or inappropriate.
ic ci ci ci ci ci ci ci ci


Answer: BMI was described with a mean and standard deviation (SD). BMI measurement resulte

d in ratio-

level data with continuous values and an absolute zero (Stone & Frazier, 2017). Ratio-
ci ci ci ci ci ci ci ci ci ci ci ci ci


level data should be analyzed with parametric statistics such as the mean and SD (Grove & Gray,
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ic


2017; Knapp, 2017). ci ci




4. Researchers used the following item to measure registered nurses’ (RNs) income in a study:
ci ci ci ci ci ci ci ci ci ci ci ci ci ic


What category identifies your current income as an RN?
ci ci ci ci ci ci ci ci


a. Less than $50,000
c i ci ci


b. $50,000 to 59,999
c i ci ci


c. $60,000 to 69,999
c i ci ci


d. $70,000 to 80,000
c i ci ci


e. $80,000 or greater

What level of measurement is this income variable? Does the income variable follow t
ci ci ci ci ci ci ci ci ci ci ci ci ci


he rules outlined in Figure 1-1? Provide a rationale for your answer.
ci ci ci ci ci ci ci ci ci ci ci


Answer: In this example, the income variable is measured at the ordinal level. The income catego

categories ensure that all salary levels are covered. The categories are not exclusive, since catego-

ries (d) and (e) include an $80,000 salary, so study participants making $80,000 might mark eit

her (d) or (e) or both categories, resulting in erroneous data. Category (e) could be changed
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ic


to greater than $80,000, making the categories exclusive. The categories can be rank ordered fr

om the lowest salary to the highest salary, which is consistent with ordinal data (Grove & Gray
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


, 2019; Waltz et al., 2017).

5. What level of measurement is the CDS score? Provide a rationale for your answer.
ci ci ci ci ci ci ci ci ci ci ci ci ci


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


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


their symp- ci


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


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


item scale are considered to be at the interval level of measurement (Gray et al., 2017; Waltz et a
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


l., 2017). ci




6. Were nonparametric or parametric analysis techniques used to analyze the CDS scores for
ci ci ci ci ci ci ci ci ci ci ci ci ic


the cardiac patients in this study? Provide a rationale for your answer.
ci ci ci ci ci ci ci ci ci ci ci


Answer: Parametric statistics, such as mean and SD, were conducted to describe CDS sc
ci ci ci ci c i c i c i c i c i c i c i c i c i


oresfor study participants (see Table 1). CDS scores are interval-
ic ci ci ci ci ci ci ci ci ci


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


Gray et al., 2017; Kim & Mallory, 2017).
ci ci ci ci ci ci ci




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


of this result.
ci ci ci


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


ater NYHA class. In NYHA class III, 64% of the subjects were depressed, whereas 11% of thesubje
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ic


cts were depressed in NYHA class I. Thus, as the NYHA class increased, the number of sub-
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


jects with depression increased. This is an expected finding because as the NYHA class increases,
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


cardiac patients have more severe physical symptoms, which usually result in emotional distress, s
ci ci ci ci ci ci ci ci ci ci ci ci ci


uch as depression. Nurses need to actively assess cardiac patients for depression, especially thos
ci ci ci ci ci ci ci ci ci ci ci ci ci


ein 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 treated with
ci ci ci ci ci ci ci ci ci ci ci ci ci ci ci


an antidepressant? Show your calculations and round your answer to the nearest whole p

Answer: A total of 106 cardiac patients participated in this study. The sample included
ci ci cici cici cici cici cici cici cici cici cici cici cici ci


15 patients who were receiving an antidepressant (see Table 1). The number of cardiac patie

nts not treated for depression was 91 (106 –
ci ci ci ci ci ci ci ci


15 = 91). The group percent is calculatedby the following formula: (group frequency

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

= 0.858 × 100% = 85.8% = 86%. The finalanswer is rounded to the nearest whole perc

9. What was the purpose of the 6- ci ci ci ci ci ci


minute walk test (6MWT)? Would the 6MWT be useful in clinical practice?
ci ci ci ci ci ci ci ci ci ci ci


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

for the exercise confidence variable in this study? Provide a rationale for your answer.
ci ci ci ci ci ci ci ci ci ci ci ci ci ci
