, 1. Multiple Choice
Case Scenario:
A nurse researcher is designing a study to evaluate the
effectiveness of a new patient education intervention. To establish
a cause–effect relationship between the intervention and patient
outcomes, she must choose an appropriate design.
Question:
Which research design is considered the gold standard for
detecting causal relationships in nursing research?
Options:
A. Cross-sectional study
B. Case-control study
C. Randomized controlled trial (RCT)
D. Ethnographic study
Correct ANS:
C. Randomized controlled trial (RCT)
Rationale:
RCTs are regarded as the gold standard because random
allocation minimizes bias, controls for confounding factors, and
enhances the internal validity necessary to establish causality.

2. Fill-in-the-Blank
Case Scenario:
A study protocol specifies detailed procedures for data collection to
ensure consistent implementation across all sites.
Question:

, Correct ANS:
standardization
Rationale:
Standardization reduces measurement error and increases the
reliability of data by ensuring that every participant is assessed
using the same methods and criteria.

3. True/False
Case Scenario:
A research team is evaluating a new survey instrument. One
member states, “If an instrument consistently produces the same
results, it must also be measuring what it’s supposed to measure.”
Statement:
A measurement instrument can be reliable without being valid.
Correct ANS:
True
Rationale:
Reliability refers to the consistency of an instrument, while validity
refers to accuracy. An instrument may consistently produce the
same results (high reliability) but still fail to measure the intended
construct (low validity).

4. Multiple Response
Case Scenario:
A nurse researcher is designing a mixed-methods study using a
convergent parallel design to evaluate both outcomes and
underlying processes.
Question:
Which elements are characteristic of a convergent parallel mixed-
