# SECTION 1: RESEARCH FOUNDATIONS & EVIDENCE-BASED PRACTICE
(25 Questions)
**Q1.** A study examines whether higher nurse staffing ratios reduce mortality
rates. This is best classified as:
A) Qualitative research
B) Quantitative research
C) Ethnographic research
D) Grounded theory research
**Answer: B** – Rationale: Staffing ratios and mortality rates are measurable
numerical variables that can be analyzed statistically. This makes the study
quantitative in nature .
**Q2.** Which is the best definition of a research hypothesis?
A) A broad topic of interest
B) A guess based on opinion
C) A testable prediction about the relationship between variables
D) A summary of existing literature
**Answer: C** – Rationale: A research hypothesis is a specific, testable prediction
about the expected relationship between independent and dependent variables. It is
formulated before data collection .

**Q3.** Which is an example of an independent variable?
A) Blood pressure after medication administration
B) Patient satisfaction score
C) The medication administered to the patient
D) The number of patient falls on a unit
**Answer: C** – Rationale: The independent variable is the variable that is
manipulated or changed by the researcher. It is the presumed "cause" that
influences the dependent variable .
**Q4.** A nurse wants to study the impact of hand hygiene education on infection
rates. Infection rates are the:
A) Independent variable
B) Dependent variable
C) Confounding variable
D) Sampling variable
**Answer: B** – Rationale: The dependent variable is the outcome that is
measured to see if it is affected by the independent variable. Infection rates depend
on (are influenced by) the hand hygiene education intervention .
**Q5.** The first step in the Evidence-Based Practice (EBP) process is:
A) Appraise the evidence critically
, 4|Page
B) Apply evidence to clinical practice
C) Formulate an answerable clinical question
D) Evaluate outcomes of the practice change
**Answer: C** – Rationale: The EBP process begins with asking a focused
clinical question (often using the PICOT format). Without a clear question,
searching for and appraising evidence lacks direction .
**Q6.** A nurse creates the question: "In ICU patients, does daily sedation
interruption compared to continuous sedation reduce ventilator days?" This is an
example of:
A) PICO question
B) Qualitative inquiry
C) Non-research clinical concern
D) Descriptive study
**Answer: A** – Rationale: This question follows the PICOT framework:
Population (ICU patients), Intervention (daily sedation interruption), Comparison
(continuous sedation), Outcome (reduced ventilator days). The format guides
evidence-based literature searches .
**Q7.** In the PICOT framework, the "T" represents:
A) Treatment
B) Timeframe
