Infection Control Quiz Questions and Answers Questions
Question 1 of 5
The infection control nurse is reviewing data for the medical-surgical unit. The nurse notices an increase in postoperative infections from Aspergillus. Which type of health care–associated infection will the nurse report?
Correct Answer: B
Rationale: The correct answer is B: Exogenous. Aspergillus is a fungus commonly found in the environment, making it an exogenous source of infection. Postoperative infections caused by Aspergillus are considered healthcare-associated infections (HAIs) because the source is external to the patient. The infection is acquired from the environment during the surgical procedure. A: Vector refers to an organism that transmits infections from one host to another, which is not the case with Aspergillus infections. C: Endogenous infections arise from the patient's own flora, not from an external source like Aspergillus. D: Suprainfection occurs when a new infection arises on top of an existing infection, which is not directly related to Aspergillus postoperative infections.
Question 2 of 5
The nurse is caring for a patient on contact precautions. Which action will be most appropriate to prevent the spread of disease?
Correct Answer: D
Rationale: Correct Answer: D Rationale: 1. Using a dedicated blood pressure cuff prevents cross-contamination. 2. Shared equipment can spread infection. 3. Dedicated equipment minimizes the risk of transmission. 4. Following contact precautions involves using dedicated items for each patient. Summary: A: Negative airflow rooms are used for airborne precautions, not contact precautions. B: While PPE is important, using dedicated equipment is more effective for contact precautions. C: Patient transport is important, but using dedicated equipment is crucial for preventing spread.
Question 3 of 5
The nurse is caring for a patient who needs a protective environment. The nurse has provided the care needed and is now leaving the room. In which order will the nurse remove the personal protective equipment, beginning with the first step?
Correct Answer: C
Rationale: Step 1: The first step in removing personal protective equipment (PPE) is to remove gloves to prevent contamination. Step 2: After removing gloves, the nurse can then proceed to remove other PPE items such as gown, eyewear, and face shield. Step 3: Removing gloves first minimizes the risk of transferring pathogens from contaminated gloves to other parts of the PPE or the nurse's skin. Step 4: This order of removal maintains proper infection control practices and reduces the risk of self-contamination. Removing gloves first is crucial in preventing the spread of infection. Other choices are incorrect because they do not follow the correct sequence for PPE removal, which could lead to contamination and compromise safety.
Question 4 of 5
Healthcare workers often contract Hepatitis B from needle-stick injuries.
Correct Answer: A
Rationale: Healthcare workers are at a higher risk of contracting Hepatitis B due to the nature of their work, which involves frequent exposure to blood and bodily fluids. Needle-stick injuries, which occur when a healthcare worker accidentally punctures their skin with a contaminated needle, are a common mode of transmission for Hepatitis B. This is why it is crucial for healthcare workers to follow strict safety protocols, such as using needle safety devices and practicing proper infection control measures, to minimize the risk of contracting Hepatitis B and other bloodborne diseases.
Question 5 of 5
Your hands and forearms should be lower than your elbows when performing hand hygiene routine.
Correct Answer: B
Rationale: Hands should be kept higher than elbows during washing to allow water and microbes to flow downward, away from the body.
