SECTION 1: RESEARCH DESIGN & METHODOLOGY Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 42-year-old nurse researcher in a surgical unit wants to determine whether a
silver-impregnated dressing reduces infection rates compared to standard gauze in
patients with diabetic foot ulcers. She obtains consent from eligible patients and uses a
computer-generated sequence to assign them to either the new dressing or the
standard care for six weeks while monitoring wound cultures. Which research design
best describes her study?
A. Randomized controlled trial with parallel groups ✓ CORRECT
B. Prospective cohort study with natural exposure groups
C. Cross-sectional descriptive survey of wound care practices
D. Case-control study comparing infected and non-infected cases
Correct Answer: A
,Rationale: This study uses random assignment to two treatment groups with a control
condition and prospective outcome measurement, which defines a randomized
controlled trial. A prospective cohort study in choice B observes naturally occurring
exposure groups without researcher-controlled randomization, which is not what
occurred here. RCTs provide the strongest evidence for causal intervention effects and
are considered the gold standard for clinical practice guideline development.
Question 2 of 50
A 29-year-old PhD student in a college of nursing is exploring how African American
women with hypertension experience medication adherence in their daily lives. She
conducts in-depth interviews with 15 participants in their homes, asking them to
describe their routines, family roles, and emotional responses to taking daily
antihypertensives. Which research design is she using?
A. Grounded theory study seeking to generate a formal theory
B. Descriptive phenomenological study exploring lived experience ✓ CORRECT
C. Ethnographic study examining cultural rituals within a community
D. Historical research analyzing archival documents and oral histories
Correct Answer: B
Rationale: Descriptive phenomenology specifically seeks to understand the essence of
lived experience through in-depth interviews with individuals who have experienced the
phenomenon of interest, which matches this student's focus on daily medication
adherence experiences. Grounded theory in choice A is tempting because it also uses
interviews, but its primary goal is theory generation rather than pure experiential
description. Phenomenological findings often inform culturally tailored nursing
interventions by revealing patient perspectives that quantitative measures miss.
Question 3 of 50
,A hospital quality improvement director needs to know the current rate of
catheter-associated urinary tract infections across all medical-surgical units on a single
day in March. She reviews every inpatient chart, records whether an indwelling catheter
is present, and notes any positive urine cultures within the previous 48 hours. Which
design classification fits this project?
A. Prospective cohort study following catheterized patients forward in time
B. Retrospective case-control study comparing infected and uninfected patients
C. Cross-sectional prevalence study measuring outcomes at one point in time ✓
CORRECT
D. True experimental study testing a new catheter maintenance protocol
Correct Answer: C
Rationale: This project collects data from the entire population of interest at a single
defined point in time to determine the prevalence of an existing condition, which is the
defining feature of a cross-sectional design. A prospective cohort study in choice A
would follow patients forward to observe incident infections over time rather than
capturing a snapshot. Cross-sectional designs are efficient for quality improvement
benchmarking but cannot establish incidence or causal relationships because exposure
and outcome are measured simultaneously.
Question 4 of 50
A nurse manager on a busy oncology unit wants to test whether playing nature sounds
during chemotherapy infusions reduces patient anxiety. Because she cannot randomize
individual patients to rooms with different sound environments, she compares anxiety
scores from the spring semester when nature sounds were played against scores from
the previous fall semester when usual care noise levels were documented. Which
design does this represent?
A. True experimental design with random assignment to conditions
B. Randomized controlled trial with blinded outcome assessment
, C. Pre-experimental one-group posttest-only design
D. Quasi-experimental design with a nonequivalent comparison group ✓ CORRECT
Correct Answer: D
Rationale: This study lacks random assignment and uses historical data from a previous
cohort as a comparison group, which defines a quasi-experimental design with
nonequivalent groups rather than a true experiment. A true experimental design in
choice A requires both randomization and researcher control over the intervention,
which the nurse manager could not achieve due to logistical constraints.
Quasi-experimental designs are common in nursing research because clinical settings
often prohibit full experimental control, though they carry higher risk of selection bias.
Question 5 of 50
A 38-year-old cardiovascular nurse researcher is studying whether a structured exercise
program improves six-minute walk distance in patients three months post-MI. She
measures baseline walk distance, assigns participants to either the exercise program or
usual care, and measures walk distance again at 12 weeks. In this study, the six-minute
walk distance at 12 weeks represents which type of variable?
A. Dependent variable representing the measured outcome ✓ CORRECT
B. Independent variable manipulated by the researcher
C. Extraneous variable influencing the outcome unintentionally
D. Moderator variable altering the strength of relationships
Correct Answer: A
Rationale: The six-minute walk distance is the outcome being measured to assess the
effect of the exercise intervention, making it the dependent variable because its value
depends on the treatment condition. The independent variable in this study is the
exercise program assignment, and confusing the intervention with the outcome is a
frequent error among beginning researchers. Choosing valid dependent variables that
