Which type of quantitative research is conducted to directly influence or improve clinical practice?
Basic research
Applied research
Experimental research
Descriptive research
The Correct Answer is B
Quantitative research can be broadly categorized based on its purpose-whether to generate theoretical knowledge or to address immediate, practical problems.
Rationale for correct answer:
B. Applied research aims to solve real-world problems and directly improve practice, making it highly relevant to clinical nursing.
Rationale for incorrect answers:
A. Basic research seeks to expand theoretical knowledge without immediate application to practice.
C. Experimental research involves manipulating variables to establish cause-effect relationships but is not always focused on direct clinical improvement.
D. Descriptive research provides detailed observations of phenomena but does not necessarily aim to change practice directly.
Take home points
- Applied research is designed to directly address practical issues and improve clinical care.
- Choosing the correct research type is essential for aligning study goals with desired patient care outcomes.

Correct Answer is B
Explanation
The PICO format is a framework used in evidence-based practice (EBP) to help clinicians formulate well-structured, answerable clinical questions and guide effective literature searches. PICO stands for Population/Problem, Intervention, Comparison, and Outcome.
Rationale for correct answer:
B. Population: "P" in the PICO format stands for Population (or sometimes Patient/Problem). It defines who the question is about-including patient demographics (age, gender, condition, setting).
Rationale for incorrect answers:
A. Patterns: While recognizing clinical patterns can be useful in practice, "Patterns" is not part of the PICO framework. It doesn’t define the group being studied or the clinical issue in question.
C.Probability is a statistical concept, not part of the PICO structure. It may be relevant in data analysis, but it doesn't help define the clinical population or frame the research question.
D. Purpose: Although a research question has a purpose, the PICO acronym is not meant to outline the study's objective, but to provide a structure for breaking down the key components of a clinical question.
Take home points:
- “P” in the PICO format stands for Population (or Patient/Problem).
- Using the PICO format strengthens evidence-based practice by helping healthcare professionals develop focused questions.
Correct Answer is A
Explanation
Nursing theories vary in scope and purpose. Some describe phenomena (descriptive), some explain growth and changes (developmental), others explore complex interactions (systems), and some directly guide clinical decision-making (prescriptive).
Rationale for correct answer:
A. Prescriptive theories guide nursing interventions, predict outcomes, and provide direct instructions for clinical practice.
Rationale for incorrect answers:
B. Descriptive theory: Descriptive theories explain or describe a phenomenon without directing specific nursing actions.
C. Developmental theory: Focuses on the process of growth and development across the lifespan, not on nursing interventions.
D. Systems theory: Examines how components of a system interact, useful for understanding healthcare environments but not specifically for guiding direct care actions.
Take home points
- Prescriptive theories are designed to guide nursing interventions and predict patient outcomes.
- Different theory types serve different purposes-choosing the right one depends on whether you’re describing, explaining, or applying nursing knowledge.
