Infection Control NCLEX Questions Questions
Question 1 of 5
The patient has contracted a urinary tract infection (UTI) while in the hospital. Which action will most likely increase the risk of a patient contracting a UTI?
Correct Answer: B
Rationale: The correct answer is B. Allowing the drainage bag port to touch the graduated receptacle increases the risk of contamination and infection as it can introduce bacteria into the urinary system. This can lead to a UTI. Reusing the receptacle (A) can also introduce bacteria but is not as direct as touching the port. Emptying the bag frequently (C) can actually decrease the risk by preventing bacterial buildup. Irrigating the catheter infrequently (D) is not ideal but is not directly related to the risk of contracting a UTI.
Question 2 of 5
The nurse is caring for a patient who has cultured positive for Clostridium difficile. Which action will the nurse take next?
Correct Answer: A
Rationale: The correct answer is A because C. difficile spores are not effectively killed by alcohol-based hand sanitizers, so instructing assistive personnel to use soap and water is crucial for proper hand hygiene. Choice B is incorrect as N95 respirators are used for airborne precautions, not for C. difficile. Choice C is incorrect as C. difficile requires contact precautions, not droplet precautions. Choice D is incorrect as it is not directly related to preventing the spread of C. difficile.
Question 3 of 5
The nurse manager is evaluating current infection control data for the intensive care unit. The nurse compares past patient data with current data to look for trends. The nurse manager examines the infection chain for possible solutions. In which order will the nurse arrange the items for the infection chain beginning with the first step?
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.
Question 4 of 5
Older people, immunocompromised people, babies, hospitalised patients and pregnant women are usually more at risk of infection. True or false?
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.
Question 5 of 5
Alcohol-based hand rub is the preferred method of hand hygiene.
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.
