Question 1 of 5
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?
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.
Question 2 of 5
Nursing students have been assigned to discuss a section of a research article examining 24-hour visitation for patients in the intensive care unit (ICU). What topic will the student assigned to the applicability section plan to discuss?
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.
Question 3 of 5
A nurse is using general systems theory to assist a family of four develop healthier food choices. What statement best reflects a key point of this theory?
Correct Answer: A
Rationale: General systems theory defines a system as a set of interacting elements contributing to the overall goal of the system. A change in one element could affect other subsystems, as well as the whole.
To survive, open systems maintain balance through feedback, in this case, family members. An open system allows energy, matter, and information to move freely between systems and boundaries, such as with members of the health care team, whereas a closed system does not allow input from or output.
Question 4 of 5
After their clinical experience, nursing students are given a reflective assignment to discuss the concepts in nursing theory that influence and determine nursing practice. What part of this theory is most important when delivering thoughtful care?
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.
Question 5 of 5
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?
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.
