A nurse is assisting with an in-service to a group of newly licensed nurses about the definition of nursing developed by the American Nurses Association (ANA). Which of the following information should the nurse include in the teaching? (Select all that apply.)

A. Quality improvement focuses on the processes and systems within healthcare that enhance patient outcomes and improve care delivery. While the nurse's actions contribute to overall quality of care, this specific scenario does not directly relate to improving a process or system.
B. The nurse is demonstrating the competency of safety by ensuring the client’s bed is locked (preventing falls) and the call light is within reach (allowing the client to request help easily). These actions directly enhance the client's safety and prevent potential harm.
C. Teamwork and collaboration involve working effectively with other healthcare professionals to provide optimal care. While collaboration is essential in nursing, the actions described do not specifically pertain to working with other team members.
D. Patient-centered care focuses on respecting and responding to individual patient preferences, needs, and values. While ensuring the call light is within reach aligns with the principles of patient-centered care, the primary focus of the nurse’s actions is on safety.

A. The reservoir is the natural habitat of the infectious agent where it lives, grows, and multiplies. In the case of hepatitis A, the reservoir could be contaminated food, water, or infected individuals. The mouth is not the reservoir; rather, it is a route through which the infection enters the body.
B. The infectious agent is the pathogen (bacteria, virus, or other microorganisms) that causes the disease. For hepatitis A, the infectious agent is the hepatitis A virus itself. The mouth is not the infectious agent; it's the entry point for the virus.
C. A susceptible host is an individual who is at risk of infection due to factors such as weakened immunity, age, or underlying health conditions. The client with hepatitis A is a susceptible host, but the mouth is not categorized as such.
D. The portal of entry is the way an infectious agent enters a susceptible host. In the case of hepatitis A acquired through contaminated food, the mouth serves as the portal of entry. The virus enters the body when the contaminated food is ingested.
