Question 1. Nurses on the cutting edge of practice promote improvement in patient outcomes
through which three primary approaches?
• A) Assessment, diagnosis, and treatment
• B) Research, evidence-based practice, and quality improvement
• C) Education, administration, and consultation
• D) Advocacy, policy, and leadership
Answer: B
Rationale: Advanced practice nurses advance patient outcomes through research (generating
new knowledge), evidence-based practice (applying best evidence), and quality improvement
(enhancing care delivery systems) .
Question 2. Nurses achieve personal growth and expand clinical decision-making skills through:
• A) Clinical intuition and experience only
• B) Development of clinical questions, literature reviews, evaluation of evidence, and
application of best available evidence
• C) Following physician orders without question
• D) Relying exclusively on traditional practices
Answer: B
Rationale: Professional growth in advanced nursing practice requires systematic development
of clinical questions, comprehensive literature reviews, critical evaluation of evidence, and
application of best evidence to practice .
Question 3. What is the primary purpose of nursing research?
• A) To validate existing nursing practices
• B) To generate new knowledge and improve patient outcomes
• C) To fulfill academic requirements
• D) To increase nursing salaries
,Answer: B
Rationale: The primary purpose of nursing research is to generate new knowledge that can be
used to improve patient care, enhance nursing practice, and contribute to the evidence base for
nursing .
Question 4. What is the difference between statistics and parameters?
• A) Statistics are analysis on a sample; parameters are analysis on the entire population
• B) Statistics are analysis on the entire population; parameters are analysis on a sample
• C) Statistics are descriptive; parameters are inferential
• D) There is no difference
Answer: A
Rationale: Statistics involves analysis on a sample, while parameters involve analysis on the
entire population .
Question 5. Quantitative data analysis includes which two main types?
• A) Descriptive and inferential
• B) Qualitative and quantitative
• C) Parametric and non-parametric
• D) Univariate and multivariate
Answer: A
Rationale: Quantitative analysis includes descriptive statistics (describing characteristics of a
population or sample) and inferential statistics (generalizing from a sample to a population) .
Question 6. What is a variable in research?
• A) A constant measurement
• B) Something that varies or takes on different values
• C) The research question
• D) The study population
Answer: B
Rationale: A variable is something that varies or takes on different values. Researchers are
always interested in variability and explaining variation .
Question 7. Which of the following is an example of a discrete variable?
, • A) Blood pressure
• B) Weight
• C) Number of children
• D) Temperature
Answer: C
Rationale: Discrete variables have a finite number of values obtained by counting. Continuous
variables (blood pressure, weight, temperature) have infinite values between any two points,
obtained by measuring .
Question 8. Which level of measurement is considered the lowest?
• A) Nominal
• B) Ordinal
• C) Interval
• D) Ratio
Answer: A
Rationale: The four levels of measurement from lowest to highest are: nominal, ordinal,
interval, and ratio. The level of measurement influences what statistical tests can be chosen .
Question 9. Which level of measurement has a true zero point?
• A) Nominal
• B) Ordinal
• C) Interval
• D) Ratio
Answer: D
Rationale: Ratio level measurement has a true zero point, allowing for meaningful ratios (e.g.,
height, weight, age). Interval level has equal intervals but no true zero.
Question 10. A research question that focuses on describing a phenomenon would use which
statistical approach?
• A) Correlation
• B) N and percentages or descriptive statistics
, • C) Independent t-test
• D) ANOVA
Answer: B
Rationale: If the question focuses on describing some phenomena, N and percentages are used
if data are nominal/categorical, or descriptive statistics (mean, standard deviation, range) if
measures are interval-like .
Question 11. If a research question is interested in a relationship between two variables, which
statistical test is appropriate?
• A) Independent t-test
• B) Correlation (Pearson's r or Spearman Rho)
• C) ANOVA
• D) Chi-square
Answer: B
Rationale: Correlation is used when the research question or hypothesis is interested in a
relationship between two variables. Pearson's r is parametric; Spearman Rho is non-parametric .
Question 12. If a research question is interested in a difference between two independent
groups, which statistical test is appropriate?
• A) Independent t-test (parametric) or Mann Whitney U (non-parametric)
• B) Paired t-test
• C) ANOVA
• D) Chi-square
Answer: A
Rationale: The independent t-test (parametric) or Mann Whitney U (non-parametric) is used
when the research question or hypothesis is interested in a difference between two
independent groups .
Question 13. If a research question is interested in a difference between two or more
independent groups, which statistical test is appropriate?
• A) Independent t-test
• B) ANOVA (parametric) or Kruskal Wallis (non-parametric)
