A nurse at an urban community health agency is developing an educational program for city leaders about homelessness.
Which of the following groups should the nurse include as the fastest growing segment of the homeless population.

Choice A rationale

Nicotine withdrawal effects are typically significant and include irritability, anxiety, difficulty concentrating, sleep disturbances, and intense craving for nicotine. These symptoms are a major barrier to cessation, making the statement that they are minimal scientifically incorrect, as nicotine is a highly addictive psychoactive substance.

Choice B rationale

Smoking is generally recognized as the leading preventable cause of death in the United States, not the fifth. Smoking causes millions of deaths annually, primarily from cardiovascular disease, lung cancer, and chronic obstructive pulmonary disease (COPD). The fifth leading cause of death is a significantly lower rank than its actual impact.

Choice C rationale

Nicotine acts as a central nervous system (CNS) stimulant, not a depressant. It acutely increases heart rate, blood pressure, and alertness by binding to nicotinic acetylcholine receptors and increasing the release of neurotransmitters like acetylcholine, dopamine, and norepinephrine, which all lead to CNS excitation.

Choice D rationale

Tolerance to nicotine develops quickly and is a hallmark of the addiction process. Rapid and repeated exposure to nicotine causes neuroadaptation, where nicotinic receptors desensitize and upregulate over time, requiring the user to consume increasing amounts of the substance to achieve the desired psychological and physiological effects.

Choice A rationale

The collective societal effort to ensure conditions for health ("What society does collectively.”.) is the definition of the mission of public health itself. This encompasses all actions, policies, and structures designed to promote health and prevent disease for the community as a whole. Social determinants of health (SDOH), however, are the underlying factors or conditions that create these health outcomes and disparities.

Choice B rationale

Comprehensive management and secure exchange of health information describes health information technology (HIT) or health informatics, which relates to the technological systems and policies used to manage patient data. While HIT can be influenced by and impact social determinants, it is a tool and a field of practice, not the intrinsic social conditions in which people live and work that fundamentally determine health status.

Choice C rationale

The context for preventing disease and promoting the health of the community is often referred to as the framework or goal of public health. Social determinants of health (SDOH) are the complex, interrelated social and economic factors—such as income, education, housing, and access to resources—that are largely responsible for health inequities, leading to the diseases and disabilities that public health seeks to prevent.

Choice D rationale

Social determinants of health (SDOH) are defined as the non-medical factors that influence health outcomes. These are the conditions in the environments where people are born, live, learn, work, play, worship, and age, which significantly shape their quality of life, risks, and health status. They include factors like socioeconomic status, education, neighborhood, and physical environment, which are root causes of health disparities.
