Practice Questions
Question 1 of 5
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?
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.
Question 2 of 5
A nurse is using the Johns Hopkins Nursing Evidence-Based Practice (JHNEBP) model PET as a clinical decision-making tool when delivering care to patients. Which steps reflect the intended use of this tool? Select all that apply.
Correct Answer: A,C,E
Rationale: The JHNEBP model is a powerful problem-solving approach to clinical decision making, which uses a three-step process called PET: practice question, evidence, and translation. The goal of the model is to ensure that the latest research findings and best practices are quickly incorporated into patient care.
Steps in PET include, but are not limited to, recruiting an interprofessional team, developing and refining the EBP question, and conducting internal and external searches for evidence.
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
A charge nurse meets with staff to outline a plan to provide transcultural nursing care for patients in their health care facility. The charge nurse explains that transcultural care as the central theme of nursing care, knowledge, and practice was promoted by which theorist?
Correct Answer: A
Rationale: 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 because of 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 nursing focus is keeping the patient system stable through accurate assessment of these stressors.
Question 5 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.
