What are the symptoms of bacterial infections?

Correct Answer: A

Rationale: The correct answer is A because nausea, vomiting, abdominal cramps, fever, and diarrhea are common symptoms of bacterial infections. B is incorrect as it refers to intoxication rather than infection. C is incorrect as encysted larvae are not indicative of bacterial infections. D is incorrect as brain inclusions are not typically associated with bacterial infections. In summary, the symptoms listed in choice A align with typical manifestations of bacterial infections, making it the correct answer.

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.

Correct Answer: A

Rationale: The correct answer is A: One third. According to data from the Centers for Disease Control and Prevention (CDC), approximately one-third of injury deaths in the US are classified as "unintentional." This includes deaths resulting from accidents such as car crashes, falls, and poisoning. The other choices are incorrect because: B: Half - While unintentional injuries are a significant cause of death, they do not account for half of all injury deaths. C: Two thirds - This choice overestimates the proportion of unintentional injury deaths. D: Nine tenths - This choice greatly overestimates the proportion of unintentional injury deaths.
