Infection Control NCLEX Questions Questions
Question 1 of 5
The nurse is caring for a patient who is susceptible to infection. Which instruction will the nurse include in an educational session to decrease the risk of infection?
Correct Answer: C
Rationale: The correct answer is C: Teaching the patient to select nutritious foods. Proper nutrition supports the immune system, reducing the risk of infection. Nutritious foods provide essential vitamins and minerals necessary for immune function. Fall prevention (Choice A) is important for safety but does not directly decrease infection risk. Taking a temperature (Choice B) is a monitoring activity and not a preventive measure against infection. Teaching about alcohol effects (Choice D) is unrelated to infection prevention.
Question 2 of 5
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.
Question 3 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 4 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 5 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: These groups have weakened or immature immune systems, making them more susceptible to infections.
