A nurse is educating student nurses about the PICO format. In the PICO format for phrasing research questions and identifying key terms for a literature search, what does the “P” stand for?
Patterns
Population
Probability
Purpose
The Correct Answer is B
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.

Explanation
Informed consent (IC) is a critical ethical and legal requirement that ensures respect for a person’s autonomy. It ensures that participants are fully informed about the purpose, procedures, risks, benefits, confidentiality, and voluntary nature of the study.
Rationale for correct answer:
A. “The informed consent (IC) provides you with complete information on the research study.” Informed consent includes comprehensive details about the study's purpose, procedures, risks, benefits, alternatives, and duration. Providing complete information helps the client make an informed decision.
B.“By reviewing the consent with you, I can make sure that you understand the study and what it means for you to participate.” One of the ethical principles of informed consent is ensuring comprehension. The nurse's role is not just to obtain a signature, but to ensure that the client fully understands what participation involves.
D. “The informed consent provides your voluntary agreement to participate in the research study.” This is the essence of informed consent. Signing the form demonstrates that the client has freely and voluntarily agreed to participate without coercion.
E.“The informed consent explains how the data collected from you will be kept confidential during and after the study.” Confidentiality is a key element of informed consent. The document explains how personal data will be protected, who will have access, and how it will be stored and used.
Rationale for incorrect answer:
C. “The informed consent provides details on the limitations of the study.” While a study’s limitations may be addressed in broader scientific discussions or the research publication, they are not typically a core part of informed consent.
Take home points:
- Informed consent is more than just a signature-it is a process of providing clear, complete, and understandable information.
- The nurse investigator plays a vital role in ensuring ethical research participation.
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.
