2.​ Toddlers : Safety issues arise due to their mobility and curiosity , including poisoning, choking, and drowning. Keep medications, poisons, and cleaning supplies in locked cabinets. Toddlers should be transported only in car seats. 3.​ School-age children : As they spend time in school and play with friends, new safety risks emerge. Emphasize the importance of traffic safety, water safety, fire safety, and awareness of the dangers posed by strangers . Children should use car seats and/or booster seats until they can properly fit adult seat belts, typically at around 4 '9", 80 lbs, and between ages 8 and 12. (Age and height/weight requirements may vary by state.) 4.​ Adolescents : Adolescents' sense of independence and invincibility, along with their access to cars, create risks. Focus on driver education, alcohol and substance abuse education, and sexual health information. 5.​ Adults : Safety risks for adults encompass home, workplace, and leisure activities . Educate adults about motor vehicle, fire, and firearm safety. 6.​ Older adults : Safety is impacted by aging issues , both physical and cognitive, particularly concerning falls and medication side effects . The possibilities of elder abuse and motor vehicle accidents also increase for older adults. B. Infection Control To effectively address questions about infection control, it's essential to grasp some fundamental information about etiologic agents and the chain of infection. An etiologic agent refers to any pathogen capable of causing an infection, such as bacteria, fungi, protozoa, rickettsiae, and helminths. The Chain of Infection comprises six key elements: 1.​ Pathogen : This is an infectious agent, such as a bacteria or virus. 2.​ Reservoirs : These are environments that support the growth and reproduction of infectious agents. Reservoirs can be animate or inanimate. Examples of human systems acting as reservoirs include blood, respiratory, gastrointestinal, reproductive, and urinary systems. 3.​ Portal of exit : This refers to the site from which infectious organisms leave a host's body. Any of the aforementioned systems can serve as portals of exit. 4.​ Method of transmission : This describes how an infectious organism is transferred from a reservoir to a host. Three primary transmission methods include direct contact, indirect contact via a vector, or airborne transmission. 5.​ Portal of entry : This is the location through which an infectious agent enters a susceptible host. A portal of entry may also be connected to a system acting as a reservoir. 6.​ Susceptible host : This refers to a client, staff member, or any individual at risk of contracting an infection.
