Infection Control Quiz Questions and Answers Questions
Question 1 of 5
What is the minimal amount of time that a nurse should scrub hands that are not visibly soiled for effective hand hygiene?
Correct Answer: A
Rationale: The correct answer is A: 20 seconds. This is in line with the CDC guidelines, which recommend scrubbing hands for at least 20 seconds for effective hand hygiene. This duration allows for adequate removal of germs and pathogens. Choices B, C, and D are incorrect as they exceed the necessary time for hand scrubbing, which can lead to unnecessary skin irritation and wastage of resources. Option B (30 seconds) is slightly longer than needed, while options C (1 minute) and D (5 minutes) far exceed the recommended time, making them impractical and potentially harmful to the skin.
Question 2 of 5
The nurse is caring for an adult patient in the clinic who has been evacuated and is a victim of flooding. The nurse teaches the patient about rest, exercise, and eating properly and how to utilize deep breathing and visualization. What is the primary rationale for the nurse’s actions related to the teaching?
Correct Answer: C
Rationale: The correct answer is C because stress can weaken the immune system, making the individual more susceptible to infections. Teaching the patient about stress management through techniques like deep breathing and visualization can help prevent exhaustion and decrease the risk of infections. Choice A is incorrect because the information provided is specific to the patient's situation, not just standard health care topics. Choice B is incorrect as it does not address the patient's immediate health needs. Choice D is incorrect because the primary focus of the teaching is on stress management and not pain or material loss.
Question 3 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 4 of 5
The nurse is caring for a patient with an incision. Which actions will best indicate an understanding of medical and surgical asepsis for a sterile dressing change?
Correct Answer: C
Rationale: The correct answer is C because it demonstrates a clear understanding of medical and surgical asepsis. By using clean gloves to remove the dressing, the nurse prevents contamination of the wound. Then, utilizing sterile supplies for the new dressing ensures a sterile environment for the wound to heal properly. Choice A is incorrect because clean goggles and gown are not necessary for a sterile dressing change, and gloves should be sterile, not just clean. Choice B is incorrect as a sterile gown is not typically required for removing a wound dressing. Choice D is incorrect because using clean supplies for the new dressing does not maintain the necessary level of sterility for wound care.
Question 5 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.
