What kinds of hazardous materials are present in medical waste?

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: 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.

Correct Answer: D

Rationale: Proper hand washing falls under the category of maintenance of accepted hygiene practices because it involves following established protocols to prevent the spread of germs and maintain personal cleanliness. It is crucial for reducing the risk of infections and illnesses. Other choices are incorrect as A pertains to equipment safety, B to personal routines, and C to workplace cleanliness, which are not directly related to the specific hygiene practice of hand washing.
