Why is it bad to systematically treat animals with antibiotics?

Correct Answer: D

Rationale: The correct answer is D because systematically treating animals with antibiotics can lead to the selection of pathogenic organisms that develop resistance to the drugs. This occurs due to the survival and proliferation of resistant strains when exposed to antibiotics, posing a significant threat to human health by potentially transferring these resistant genes to humans through food consumption. Choices A, B, and C are incorrect as raising the cost of meat, making animals sick, and developing resistance to drugs are not the primary concern associated with the misuse of antibiotics in animal agriculture.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." Medical waste can contain infectious agents like bacteria and viruses, toxic chemicals like chemotherapy drugs or disinfectants, and sources of radiation such as used radioactive materials. It is important to handle medical waste carefully to prevent exposure to these hazardous materials. Choices A, B, and C are incorrect individually as they only represent a part of the hazardous materials present in medical waste. The correct answer encompasses all potential hazards found in medical waste, making it the most comprehensive and accurate choice.

Correct Answer: B

Rationale: The correct answer is B because workers in jobs involving physical labor and risk of injury are more likely to be prescribed opioids for pain management, leading to increased risk of opioid dependence. Physical labor can result in injuries requiring pain relief, increasing exposure to opioids. Low-paying jobs (A) do not directly relate to opioid dependence. Unfulfilling work (C) may contribute to mental health issues but not specifically opioid dependence. Having access to opioids through work (D) is a consequence of the physical labor and risk of injury, not the primary reason for increased risk.

Correct Answer: D

Rationale: The correct answer is D because Personal Protective Equipment (PPE) is at the bottom of the hierarchy of control as it is the least effective method for controlling hazards. A: PPE may not be effective if not worn properly - True, improper use reduces effectiveness. B: PPE may not be effective if not worn consistently - True, inconsistent use leaves individuals exposed. C: PPE may cause other safety issues - True, improper use can lead to issues like restricted movement or impaired vision. Therefore, D is correct as it encompasses all the reasons why PPE is considered the least effective control measure.

Correct Answer: D

Rationale: The correct answer is D: Intentional deaths. Suicide and homicide are intentional acts where an individual deliberately takes their own life or causes the death of another person. This choice is correct as it accurately reflects the intentional nature of these actions. A: Unintentional injuries - This choice is incorrect as suicide and homicide are deliberate actions, not accidental injuries. B: Undetermined deaths - This choice is incorrect as suicide and homicide have clear intent behind them, unlike undetermined deaths where the cause is unknown. C: Determined deaths - This choice is incorrect as it does not capture the intentional aspect of suicide and homicide.
