Infection Control Nursing Questions
Question 1 of 5
A nurse is preparing discharge instructions for an 89-year-old client with a stage 4 pressure injury on his coccyx. The caregiver has been trained on wound dressing changes and cleansing. The caregiver asks the nurse how they can prevent infection in the wound. Which answer by the nurse is most appropriate?
Correct Answer: D
Rationale: The correct answer is D: “Wear gloves and use the sterile or aseptic supplies provided to you when changing the client’s dressing.” This answer is correct because wearing gloves and using sterile supplies help prevent introducing harmful bacteria into the wound, reducing the risk of infection. Gloves provide a barrier to protect both the caregiver's hands and the wound from contamination. Sterile supplies minimize the introduction of pathogens into the wound, promoting healing and preventing infection. A: “Change the wound dressing only once a day.” - This answer is incorrect because the frequency of dressing changes should be based on the healthcare provider's instructions and the wound's condition, not a fixed schedule. B: “Use protective eyewear while changing the wound dressing.” - While protective eyewear is important in certain situations, it is not directly related to preventing wound infection in this context. C: “Pressure injuries rarely cause infections to worry about.” - This answer is incorrect because all wounds, including pressure injuries, are susceptible to infection
Question 2 of 5
A nurse is teaching a client how to use a walker for the first time. Place the following steps in the appropriate order:
Correct Answer: A
Rationale: The correct order is A. Placing both hands on the handles first ensures proper grip and stability. This step is crucial for maintaining balance and control while using the walker. Steps B and D follow after establishing a stable grip to ensure proper weight distribution and prevent falls. Step C is last as moving the walker forward should only be done after securing a firm hold on the handles to avoid accidents.
Question 3 of 5
The nurse has received a report from the emergency department that a patient with tuberculosis will be coming to the unit. Which items will the nurse need to care for this patient? (Select all that apply.)
Correct Answer: B
Rationale: Step-by-step rationale: 1. Tuberculosis is an airborne disease, so negative-pressure airflow is needed to prevent the spread of infectious particles. 2. Negative-pressure rooms prevent contaminated air from escaping, reducing the risk of transmission. 3. Private room alone may not be sufficient to contain airborne pathogens. 4. Choice C includes standard precautions, not specific to tuberculosis. 5. N95 respirator is not necessary for routine care of tuberculosis patients. Summary: The correct answer is B because negative-pressure airflow in the room is essential to prevent the spread of tuberculosis. Other choices do not specifically address airborne precautions for this disease.
Question 4 of 5
A nurse caring for a client who has gas gangrene knows that this infection originated in which of the following reservoirs?
Correct Answer: C
Rationale: The correct answer is C: Soil. Gas gangrene is caused by Clostridium perfringens bacteria, which is commonly found in soil. The spores enter the body through contaminated wounds. Other people (A) are not the primary reservoir for this infection. While contaminated food (B) can lead to food poisoning, it is not the source of gas gangrene. Animals (D) can transmit certain infections, but they are not the reservoir for Clostridium perfringens that causes gas gangrene.
Question 5 of 5
Of all possible nursing interventions to break the chain of infection, which is the most effective?
Correct Answer: C
Rationale: The correct answer is C: Practicing hand hygiene. Hand hygiene is the most effective nursing intervention to break the chain of infection because it helps prevent the transmission of pathogens from person to person. By washing hands regularly, nurses can reduce the risk of spreading infections to patients and themselves. Administering medications (A) is important for treatment but does not directly prevent the transmission of infections. Providing good skin care (B) is essential for overall health but may not specifically target infection prevention. Wearing gloves at all times (D) is crucial in certain situations but does not replace the importance of hand hygiene in breaking the chain of infection.
