Infection Control NCLEX Questions Questions
Question 1 of 5
After preparing a sterile field, which of the following statements are true?
Correct Answer: D
Rationale: The correct answer is D because opened sterile instruments on the sterile field are considered sterile. This is because sterile instruments are only placed on the sterile field after they have been properly sterilized and packaged. Placing them on the sterile field ensures that they remain free from contamination. It is crucial to maintain the sterility of instruments to prevent infection during procedures. Choices A, B, and C are incorrect: A: The outer 1 inch of the sterile field should be considered sterile to prevent contamination. B: After applying sterile gloves, hands should be kept above the waistline to maintain sterility. C: Walking in and out of the room can introduce contaminants to the sterile field, compromising its sterility.
Question 2 of 5
The nurse is assessing a new patient admitted to home health. Which questions will be most appropriate for the nurse to ask to determine the risk of infection? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A because asking the patient to explain the risk for infection in their home assesses their understanding and awareness of potential infection sources. This information helps the nurse to identify specific risks and provide appropriate education. Choice B is incorrect as it focuses on travel history which may not directly relate to the patient's risk of infection at home. Choice C is incorrect as handwashing demonstration assesses the patient's knowledge of hygiene practices but does not directly determine their risk of infection. Choice D is incorrect as it evaluates the patient's knowledge of infection signs and symptoms but does not assess their risk factors.
Question 3 of 5
The nurse is aware that an antiviral medication is most effective when given during which phase of the infectious process?
Correct Answer: A
Rationale: The correct answer is A: Prodromal stage. During this phase, the virus is multiplying rapidly, and symptoms are just starting to appear. Administering antiviral medication at this stage can help reduce viral replication and prevent the infection from progressing further. In contrast, the other options are not ideal for antiviral treatment: B (Incubation period) is when the virus is replicating but symptoms are not yet present, C (Full stage of illness) is when symptoms are most severe and the virus has already caused significant damage, and D (Convalescent period) is when the body is recovering and the virus is being cleared naturally.
Question 4 of 5
A woman tests positive for the human immunodeficiency virus antibody but has no symptoms. She is considered a carrier. What component of the infection cycle does the woman illustrate?
Correct Answer: A
Rationale: The correct answer is A: A reservoir. In this scenario, the woman testing positive for HIV antibody but having no symptoms indicates that she is a reservoir of the virus. A reservoir is a place where infectious agents (in this case, HIV) can persist and reproduce without causing symptoms in the carrier. Other choices are incorrect because the woman is not actively transmitting the virus (infectious agent), the virus is not exiting her body (portal of exit), and she is not being newly infected (portal of entry).
Question 5 of 5
Which of the following questions asked by the nurse when taking a client’s health history would collect data about infection control?
Correct Answer: D
Rationale: The correct answer is D because asking when the client completed their immunizations collects data about their vaccination status, which is crucial for infection control. This information helps assess the client's immunity against preventable diseases and identifies potential gaps in immunization coverage. Option A focuses on dietary habits, B on sleep patterns, and C on family medical history, none of which directly relate to infection control.
