Infection Control Quiz Questions and Answers Questions
Question 1 of 5
Which characteristic of carbon monoxide makes it a particularly dangerous gas?
Correct Answer: B
Rationale: The correct answer is B because carbon monoxide binds strongly to hemoglobin, reducing the blood's ability to carry oxygen, leading to potential lung damage. Choice A is incorrect because carbon monoxide does not primarily affect the mouth. Choice C is incorrect because carbon monoxide primarily affects the respiratory system, not the spleen or liver. Choice D is incorrect because carbon monoxide binds to hemoglobin, reducing its oxygen-carrying capacity, rather than causing overproduction.
Question 2 of 5
A patient who has been placed on Contact Precautions for Clostridium difficile (C. difficile) asks you to explain what he should know about this organism. Which statements made by the patient show an understanding of the patient teaching? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: "Hands should always be cleaned with soap and water rather than the alcohol-based hand sanitizer." Rationale: 1. C. difficile spores are not effectively killed by alcohol-based hand sanitizers. 2. Washing hands with soap and water is essential for removing spores. 3. Proper hand hygiene is crucial to prevent the spread of C. difficile. 4. This statement reflects understanding of the importance of hand hygiene in preventing transmission of C. difficile. Incorrect Choices: A: Incorrect. While C. difficile is transmitted through the fecal-oral route, this statement does not directly address patient teaching on prevention. C: Incorrect. While gowns and gloves are necessary in Contact Precautions, this statement does not emphasize the importance of hand hygiene. D: Incorrect. Patients on Contact Precautions may leave the room but should practice proper hand hygiene to prevent transmission.
Question 3 of 5
Which of the following actions by the nurse demonstrate the practice of core principles of surgical asepsis? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Keep the sterile field in view at all times. This is a core principle of surgical asepsis as it helps prevent contamination by ensuring constant vigilance over the sterile field. Choice A is incorrect because the entire sterile gown, not just the front and sides, is considered sterile. Choice C is incorrect as the outer 2.5 cm of the sterile field is actually considered sterile to allow for handling without contaminating the inner field. Choice D is incorrect as all personnel in the vicinity of the sterile field, not just those within it, should wear personal protective equipment to maintain asepsis.
Question 4 of 5
The nurse at a family practice is responsible for reviewing home safety issues with all patients. She knows that there is an increased risk of falls in which of these two groups of patients?
Correct Answer: B
Rationale: The correct answer is B, toddlers and the elderly. Toddlers are at risk due to their curious nature and lack of coordination, while the elderly are at risk due to decreased balance and strength. School-age children are more coordinated and less prone to falls, infants lack mobility, and infants and the elderly are not directly comparable in terms of fall risk.
Question 5 of 5
A nurse is volunteering in an indigent clinic. She is seeing a patient whom she suspects has active tuberculosis. In this disease process, which of the following body systems serves as both the reservoir and portal of entry for this infection?
Correct Answer: B
Rationale: The correct answer is B, the respiratory system. In active tuberculosis, Mycobacterium tuberculosis is primarily transmitted through aerosolized droplets via the respiratory system. The lungs serve as both the reservoir, where the bacteria can multiply and thrive, and the portal of entry, allowing the organism to enter the body. The gastrointestinal system (A) is not the primary site for tuberculosis infection. The integumentary system (C) is the skin, which is not the reservoir or portal of entry for tuberculosis. The hematologic system (D) refers to the blood and is not the primary site for tuberculosis infection.
