Practice Questions
Question 1 of 5
A nurse is formulating a clinical question using the PICOT format. The nurse begins with determining the 'P,' which focuses on which element?
Correct Answer: D
Rationale: The P in the PICOT format represents an explicit description of the patient population of interest. I represents the intervention, C represents the comparison, O stands for the outcome, and T stands for the time.
Question 2 of 5
A Alexandrovich, A. B. (2016). An evidence-based approach to addressing healthcare issues of the LGBTQ community. The Journal for Nurse Practitioners, 12(9), 607-613.
Correct Answer: C
Rationale: Federal regulations require that institutions receiving federal funding or conducting studies of drugs or medical devices regulated by the Food and Drug Administration establish institutional review boards (IRBs). The IRBs review studies conducted in the institution to determine the risk status of the studies and to ensure that ethical principles are followed. While organizations may have internal procedures for conducting research, such as including surgeons, the director of nursing, the pharmacy director, and staff, these are not government mandates. The type of study, such as randomized-controlled study, will be determined by the nurse in collaboration with the prescriber and approval of the IRB.
Question 3 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 4 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 5 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.
