- A. Description of the tool that was used to gather the data
- B. How the results could be used in the student's practice
- C. Statistical methods used to determine the results
- D. Whether informed consent was obtained from the participants
Correct Answer: B
Rationale: Applicability refers to how study results could be used in practice. Method includes the design and data analysis. Informed consent affirms the patient's right to agree to participate in a study without coercion, to refuse to participate without jeopardizing their care, the right to confidentiality, the right to be protected from harm, and the ability to withdraw from the study at any time.

A nurse is conducting qualitative research to study the culture of Native Alaskans and how their diet affects their overall state of health. Which method of research is the nurse using?
- A. Historical
- B. Ethnography
- C. Grounded theory
- D. Phenomenology
Correct Answer: B
Rationale: Ethnographic research was developed by the discipline of anthropology and is used to examine issues of culture of interest to nurses. Historical research examines events of the past to increase understanding of the nursing profession today. The basis of grounded theory methodology is the discovery of how people describe their own reality and how their beliefs are related to their actions in a social scene. The purpose of phenomenology (both a philosophy and a research method) is to describe experiences as they are lived by the subjects being studied.
A nurse is conducting quantitative research to examine which of two types of silicone foam sacral dressings best prevent pressure injuries in bedridden patients. What type of research is the nurse conducting?
- A. Descriptive
- B. Correlational
- C. Quasi-experimental
- D. Experimental
Correct Answer: C
Rationale: Quasi-experimental research is often conducted in clinical settings to examine the effects of nursing interventions on patient outcomes. Descriptive research is often used to generate new knowledge about topics with little or no prior research. Correlational research examines the type and degree of relationships between two or more variables. Experimental research examines cause-and-effect relationships between variables under highly controlled conditions.
A nurse conducting quantitative research hypothesizes that adolescents with anorexia nervosa who participate in outpatient therapy report less depression than those receiving inpatient treatment. What information does the nurse collect to support the hypothesis?
- A. Subjects' demographics
- B. Variables
- C. Data
- D. Instruments
Correct Answer: C
Rationale: Data refer to information that the researcher collects from subjects in the study, generally expressed in words, numbers, graphs, and charts. A variable is something (such as conditions, equipment, interventions) that varies and has different values (outcomes) that can be measured. Instruments are devices used to collect and record the data, such as rating scales, pencil-and-paper tests, and biologic measurements.
A nursing student questions the primary nurse about instilling air into a nasogastric tube to confirm placement, when they learned that x-ray validation of the tube's tip in the stomach reflects best practice. The student is validating safe nursing practice with which type of knowledge?
- A. Instinctive knowledge
- B. Scientific knowledge
- C. Authoritative knowledge
- D. Traditional knowledge
Correct Answer: B
Rationale: Scientific knowledge is obtained through the scientific method or research; this leads to evidence-based practice. Instinct, such as 'I feel this is correct,' is not a source of knowledge. Traditional knowledge is the part of nursing practice passed down from generation to generation, often without research data to support it. Examples include daily bathing and changing bed linens each day. Authoritative knowledge comes from an expert and is accepted as truth based on the person's perceived expertise.

Correct Answer: D
Rationale: Of the four concepts, the most important is the person. The focus of nursing, regardless of definition or theory, is the person.
