Which infectious disease intervention best represents primary prevention?

Correct Answer: A

Rationale: The correct answer is A because giving a tetanus booster every 10 years is an example of primary prevention. This intervention aims to prevent the occurrence of tetanus by boosting immunity before exposure to the bacteria. Choice B is incorrect as it represents secondary prevention by providing treatment after exposure. Choice C is also incorrect as it is a form of passive immunization after exposure. Choice D is incorrect as it involves treatment after the disease has already manifested, which is considered tertiary prevention.

Correct Answer: C

Rationale: The correct answer is C because teaching new employees about signs and symptoms of heat-related illness is an example of primary prevention. This scenario aims to prevent heat-related illnesses before they occur by educating employees on how to recognize and avoid such risks. Choice A is incorrect as it involves detection, not prevention. Choice B is incorrect as it is a form of secondary prevention by treating an already occurred event. Choice D is incorrect as it involves early detection rather than prevention of lung diseases.

Correct Answer: A

Rationale: The correct answer is A: Local and regional boards of health. Local inspections of restaurants are typically conducted by local health departments or boards of health, as they are responsible for ensuring compliance with food safety regulations at the local level. These boards have the authority and expertise to inspect food establishments within their jurisdiction. Choice B (Environment Canada) is incorrect as they focus on environmental protection, not food safety inspections. Choice C (Provincial/territorial Ministry of Labour) is incorrect as their focus is on labor-related issues, not food safety inspections. Choice D (Health Canada) is incorrect as they oversee national health regulations, not local restaurant inspections.

Correct Answer: A

Rationale: The correct answer is A because the mitigation phase aims to prevent or reduce the impact of disasters before they occur. Mitigation involves planning, implementing measures, and building resilience to minimize the effects of disasters. This proactive approach helps to lessen the damage, save lives, and protect property. Choices B, C, and D are incorrect because mitigation occurs before the disaster, not during or after. During a disaster (B) and immediately following it (C), the focus shifts to emergency response and recovery efforts, while the recovery period (D) deals with rebuilding and restoring affected areas.

Correct Answer: A

Rationale: The correct answer is A because the ultimate goal of a disaster preparedness plan is to reduce injuries by effectively planning and implementing measures to mitigate the impact of disasters on individuals and communities. This involves strategies such as early warning systems, evacuation procedures, and emergency response training. Choice B is incorrect because while collaboration among community partners is important in disaster preparedness, it is not the ultimate goal of the plan. Choice C is incorrect because while reducing stress and panic behaviors is a positive outcome, it is not the primary purpose of a disaster preparedness plan. Choice D is incorrect because a disaster preparedness plan aims to increase involvement and preparedness, not reduce it.
