Module 1: Foundations of Nursing Inquiry, Problem Statements & Hypotheses (Questions
1–19)
Question 1
A nurse researcher formulates a research hypothesis stating, "Infants receiving skin-to-skin care
will demonstrate significantly lower pain scores during heel lance procedures compared to
infants receiving standard crib care." What type of hypothesis is represented?
• A) Non-directional, complex hypothesis
• B) Directional, simple research hypothesis
• C) Null hypothesis of no difference
• D) Causal non-directional hypothesis
Correct Answer: B) Directional, simple research hypothesis
This hypothesis predicts the specific direction of the outcome (lower pain scores) between one independent
variable (skin-to-skin care vs. standard care) and one dependent variable (pain score).
Question 2
Which statement best characterizes the primary distinction between a directional and a non-
directional research hypothesis?
• A) Directional hypotheses address qualitative outcomes while non-directional hypotheses address quantitative
variables.
• B) Directional hypotheses specify the expected nature or trend of the relationship, whereas non-
directional hypotheses state a relationship exists without specifying its trend.
• C) Non-directional hypotheses are tested strictly using non-parametric statistics.
• D) Directional hypotheses are synonymous with statistical null hypotheses.
Correct Answer: B) Directional hypotheses specify the expected nature or trend of the relationship, whereas
non-directional hypotheses state a relationship exists without specifying its trend.
Directional hypotheses explicitly state the predicted direction of difference or correlation (e.g., greater, lower,
positive), whereas non-directional hypotheses merely postulate that a difference or relationship exists.
,Question 3
In a study evaluating the impact of nurse-to-patient ratios on inpatient fall rates, what role does
the nurse-to-patient ratio fulfill in the research framework?
• A) Dependent variable
• B) Independent variable
• C) Extraneous confounding variable
• D) Mediating qualitative indicator
Correct Answer: B) Independent variable
The independent variable is the presumed cause, intervention, or antecedent condition being manipulated or
observed to measure its effect on the dependent outcome (fall rates).
Question 4
What fundamental paradigm underpins quantitative nursing research by asserting that objective
reality exists independently of human perception and can be measured empirically?
• A) Positivism / Post-positivism
• B) Constructivism
• C) Critical social theory
• D) Hermeneutic phenomenology
Correct Answer: A) Positivism / Post-positivism
Positivism asserts that objective reality is governed by natural laws, favoring quantitative measurement,
deductive logic, and controlled experimentation to establish empirical truth.
Question 5
A researcher defines operationalization in a quantitative study examining post-operative patient
anxiety. Which description represents an operational definition of anxiety?
• A) A feeling of dread, apprehension, or tension experienced after surgical procedures
• B) A patient's total score on the State-Trait Anxiety Inventory (STAI) measured 2 hours post-surgery
• C) The biological stress response mediated by the hypothalamic-pituitary-adrenal axis
• D) The lived psychological experience of vulnerability following anesthesia
Correct Answer: B) A patient's total score on the State-Trait Anxiety Inventory (STAI) measured 2 hours post-
surgery
An operational definition specifies the precise procedures, instruments, or empirical metrics used to
measure a abstract concept in a specific study.
Question 6
Which clinical research component is captured by the letter "I" in the standard PICO framework
for evidence-based practice questions?
• A) Implementation timeline
• B) Institutional setting
• C) Intervention or interest area
• D) Individual patient preference
Correct Answer: C) Intervention or interest area
PICO stands for Population/Patient (P), Intervention/Interest (I), Comparison (C), and Outcome (O). The "I"
designates the specific treatment, diagnostic test, or exposure evaluated.
, Question 7
A nurse researcher conducts a comprehensive literature review. Which source represents a
primary source for an academic research synthesis?
• A) An original research report written by the investigators who conducted the empirical study
• B) A systematic review summarizing ten independent clinical trials
• C) A nursing textbook chapter discussing research findings
• D) A clinical practice guideline published by a professional association
Correct Answer: A) An original research report written by the investigators who conducted the empirical
study
Primary sources are original, firsthand reports written directly by the researchers who designed,
implemented, and analyzed the study. Syntheses and reviews are secondary sources.
Question 8
What is the primary function of a theoretical framework in a quantitative nursing research
design?
• A) To establish statistical power for sample size determination
• B) To provide a conceptual structure that links variables and guides hypothesis development
• C) To satisfy institutional review board ethical criteria
• D) To eliminate external validity threats
Correct Answer: B) To provide a conceptual structure that links variables and guides hypothesis
development
A theoretical framework offers a logical structure grounded in existing theory, illustrating interrelationships
among concepts to guide research design, variable selection, and data interpretation.
Question 9
Which statement represents a statistical null hypothesis ($H_0$)?
• A) Patients receiving chlorhexidine baths will have lower central line infection rates than those bathed with soap
and water.
• B) There is no difference in central line infection rates between patients receiving chlorhexidine baths and
those receiving soap and water baths.
• C) Chlorhexidine baths will significantly improve skin integrity over standard care.
• D) Decreased central line infection rates are correlated with chlorhexidine bathing frequency.
Correct Answer: B) There is no difference in central line infection rates between patients receiving
chlorhexidine baths and those receiving soap and water baths.
The null hypothesis asserts that no true relationship, effect, or difference exists between study variables in
the target population, serving as the baseline proposition subjected to statistical testing.
Question 10
A investigator explores how organizational culture influences registered nurse burnout. What
variable type represents nurse burnout in this study design?
• A) Dependent variable
• B) Independent variable
• C) Manipulated intervention
• D) Categorical predictor
Correct Answer: A) Dependent variable
The dependent variable represents the outcome or effect that is measured to determine how it responds to
changes in the independent variable (organizational culture).
