Which method of qualitative research was developed by the discipline of anthropology? a) Historical b) Ethnography c) Grounded theory d) Phenomenology
b) Ethnography Ethnographic research was developed by the discipline of anthropology and is used to examine issues of culture of interest to nursing. 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 researcher must decide on the method for conducting the research. The researcher that plans to emphasize collection of numerical data and analysis would select which method of research? a) Quantitative research b) Qualitative research c) Applied research d) Basic research
a) Quantitative research

Which theorist promoted this type of caring as the central theme of nursing care, knowledge, and practice? a) Madeline Leininger b) Jean Watson c) Dorothy E. Johnson d) Betty Newman
a) Madeline Leininger Madeline Leininger's theory provides the foundations of transcultural nursing care by making caring the central theme of nursing. Jean Watson stated that nursing is concerned with promoting and restoring health, preventing illness, and caring for the sick. The central theme of Dorothy E. Johnson's theory is that problems arise due to disturbances in the system or subsystem or functioning below optimal level. Betty Newman proposed that humans are in constant relationship with stressors in the environment and the major concern for nursing is keeping the patient system stable through accurate assessment of these stressors.

This answer is an example of what type of knowledge? a) Instinctive knowledge b) Scientific knowledge c) Authoritative knowledge d) Traditional knowledge
d) Traditional knowledge Traditional knowledge is the part of nursing practice passed down from generation to generation, often without research data to support it. Scientific knowledge is that knowledge obtained through the scientific method(implying thorough research). Authoritative knowledge comes from an expert and is accepted as truth based on the person's perceived expertise. Instinct is not a source of knowledge.
A nursing student is describing building nursing theory during a fundamentals nursing class. The student describes that a theory can be built by looking at an idea as a whole and then breaking the idea down into smaller, more specific ideas. The nursing instructor knows that the student is describing which of the following? a) Theory b) Deductive reasoning c) Inductive reasoning d) Concepts
b) Deductive reasoning Deductive reasoning involves looking at an idea as a whole and then considering more specific ideas. Theory is a group of concepts and the relationships among them. Concepts are abstract ideas or objects and their relationships to one another. Inductive reasoning is derived from consideration of specific properties to conclusions about a general idea.

A nurse observes that the past five patients referred from a certain community clinic have been treated for drug and/or alcohol overdose. Based on this information, the nurse assumes that the clinic specializes in the treatment of substance abuse. This is an example of what type of reasoning? a) Nursing process b) Deductive reasoning c) General systems theory d) Inductive reasoning
d) Inductive reasoning Inductive theory describes how to break whole things into parts and then to learn how the parts work together in "systems." It emphasizes relationships between the whole and the parts and describes how parts function and behave. Reasoning is when the research builds from a specific idea or action to conclusions about general ideas. Deductive reasoning is the opposite of inductive reasoning. Deductive reasoning is research where a general idea is the starting point, then considers specific actions or ideas.
A nurse is completing a family assessment on a routine home health visit. The parents have a child with a severe peanut allergy.

A nurse is using general systems theory to describe the role of nursing to provide health promotion and patient teaching. Which statements reflect key points of this theory? Select all that apply. a) A system is a set of individual elements that rarely interact with each other. b) The whole system is always greater than its parts. c) Boundaries separate systems from each other and their environments. d) A change in one subsystem will not affect other subsystems. e) To survive, open systems maintain balance through feedback. f) A closed system allows input from and to the environment.
b, c, e According to general systems theory, a system is a set of interacting elements contributing to the overall goal of the system. The whole system is always greater than its parts. Boundaries separate systems from each other and their environments. Systems are hierarchical in nature and are composed of interrelated subsystems that work together in such a way that a change in one element could affect other subsystems, as well as the whole. To survive, open systems maintain balance through feedback. An open system allows energy, matter, and information to move freely between systems and boundaries, whereas a closed system does not allow input from or output to the environment.

Select all that apply. a) A nurse interviews and examines a new patient diagnosed with prehypertension to formulate a care plan. b) A nurse draws from personal experiences of being a patient to establish a therapeutic relationship with a patient. c) A nurse searches the Internet to find the latest treatments for type 2 diabetes. d) A nurse uses spiritual training to draw strength when counseling a patient who is in hospice for an inoperable brain tumor. e) A nurse follows the protocol for assessing postoperative patients in the ICU. f) A nursing student studies anatomy and physiology of the body systems to understand the disease states of assigned patients.
b, d. Philosophy is the study of wisdom, fundamental knowledge, and the processes used to develop and construct one's perceptions of life. A philosophy is developed from personal experiences (such as the experience of being the patient), through formal and informal educational experiences, through religion and culture (such as using spiritual training as a source of strength), and from the environment. Interviewing and examining patients to formulate a care plan and using protocol for assessing patients in the ICU involve knowledge of processes. Researching the Internet and studying anatomy and physiology use scientific knowledge to deliver evidence-based care.
