Infection Control Quiz Questions and Answers Questions
Question 1 of 5
The latest CDC guidelines designate standard precautions for all substances except which of the following?
Correct Answer: C
Rationale: The correct answer is C: Sweat. Standard precautions are recommended for all bodily fluids and substances that may contain bloodborne pathogens. Sweat does not typically contain a significant amount of pathogens compared to blood, urine, and vomitus. Therefore, the CDC guidelines do not designate standard precautions for sweat. Urine (A), blood (B), and vomitus (D) are all bodily fluids that can potentially contain pathogens and require standard precautions to prevent transmission of infections.
Question 2 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 3 of 5
A female adult patient presents to the clinic with reports of a white discharge and itching in the vaginal area. A nurse is taking a health history. Which question is the priority?
Correct Answer: C
Rationale: The correct answer is C: "What medications are you currently taking?" This is the priority question because it helps the nurse assess if the symptoms could be related to any medications the patient is currently taking. Certain medications can cause vaginal discharge or itching as side effects. A: "When was the last time you visited your primary health care provider?" - While important for overall health history, it is not as critical as determining current medications. B: "Has this condition affected your eating habits in any way?" - While dietary habits can affect overall health, it is not directly relevant to the current symptoms. D: "Are you able to sleep at night?" - While sleep is important, it is not the priority when assessing a patient with vaginal discharge and itching.
Question 4 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 5 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.
