The nurse is observing a family member changing a dressing for a patient in the home health environment. Which observation indicates the family member has a correct understanding of how to manage contaminated dressings?

Correct Answer: A

Rationale: The correct answer is A because placing used dressings in a plastic bag helps contain and prevent the spread of contaminants. This practice reduces the risk of exposure to infectious materials. Option B is incorrect as saving part of the dressing can lead to contamination. Option C is incorrect because removing gloves before gathering items may lead to potential exposure. Option D is incorrect as wrapping the dressing in toilet tissue is not a secure method of containment. Overall, option A is the best choice for proper management of contaminated dressings.

Correct Answer: B

Rationale: The correct order for the infection chain starts with the infectious agent or pathogen (B). This is the initial element that causes infection. Next is the reservoir or source for pathogen growth (D), where the pathogen resides and multiplies. Then comes the mode of transmission (A), which refers to how the pathogen is spread. Finally, the susceptible host (C) is the last in the chain, as they are the individual who can be infected. Understanding this sequence is crucial for effective infection control. The other choices are incorrect because they do not follow the logical progression of how infections occur in the chain.

Correct Answer: A

Rationale: Infection control is a critical aspect of healthcare, and understanding the populations that are more vulnerable to infections is essential for all healthcare professionals. The correct answer is A) TRUE. Older people, immunocompromised individuals, babies, hospitalized patients, and pregnant women are indeed more at risk of infections due to various factors. Older individuals often have weakened immune systems, making them more susceptible to infections. Immunocompromised individuals, such as those with HIV/AIDS or undergoing chemotherapy, have a compromised ability to fight off infections. Babies have developing immune systems, making them more vulnerable. Hospitalized patients are exposed to pathogens in healthcare settings, increasing their risk. Pregnant women experience changes in their immune system, leaving them more susceptible to certain infections. Option B) FALSE is incorrect because the statement provided in the question is accurate based on the vulnerabilities of these specific populations. Options C) and D) are not applicable as the correct answer is A. Educationally, understanding the populations at higher risk of infections is crucial for providing appropriate care, implementing infection control measures, and preventing the spread of diseases in healthcare settings. Healthcare professionals must tailor their infection control practices to protect these vulnerable groups effectively.

Correct Answer: A

Rationale: In the context of infection control and hand hygiene, the statement that "Alcohol-based hand rub is the preferred method of hand hygiene" is indeed TRUE. The rationale behind this is based on evidence-based practice and recommendations from healthcare agencies like the CDC and WHO. Alcohol-based hand rubs are highly effective in killing a broad spectrum of germs, including bacteria and viruses, and they are quick and convenient to use, making compliance more likely among healthcare workers. Choosing option B) FALSE would be incorrect because alcohol-based hand rubs have been proven to be more effective than handwashing with soap and water in many situations, especially in healthcare settings where quick and frequent hand hygiene is essential to prevent the spread of infections. While handwashing with soap and water is still important in certain situations, such as when hands are visibly soiled, alcohol-based hand rubs are generally preferred due to their efficacy and convenience. Educationally, understanding the rationale behind the preference for alcohol-based hand rubs helps healthcare professionals make informed decisions about hand hygiene practices in their daily work. It emphasizes the importance of using evidence-based methods to prevent healthcare-associated infections and protect both patients and healthcare workers. By knowing when and how to use alcohol-based hand rubs effectively, healthcare professionals can contribute to a safer healthcare environment for everyone involved.

Correct Answer: C

Rationale: In the context of infection control, understanding the origin and transmission of different infections is crucial for healthcare professionals. Gas gangrene is a type of infection caused by the bacterium Clostridium perfringens, which is commonly found in soil. Therefore, the correct answer is C) soil. Choosing option A) other people is incorrect because gas gangrene is not a contagious infection that spreads from person to person. Option B) food is also incorrect as gas gangrene is not typically transmitted through food. Option D) animals is incorrect as well because while some Clostridium species can be found in animals, gas gangrene specifically originates from soil contaminated with the bacteria. Educationally, this question highlights the importance of understanding reservoirs of infections to implement appropriate infection control measures. It emphasizes the need for healthcare providers to be knowledgeable about the sources of different infections to prevent their spread and provide effective care to patients.
