Chapter 23 Questions
Question 1 of 5
The nursing instructor explaining infection tells students that which factor is the best and most important barrier to infection.
Correct Answer: D
Rationale: The skin and mucous membranes are the most important barrier against infection because they provide a physical and chemical barrier that prevents pathogens from entering the body. The other options are also barriers, but are considered secondary to skin and mucous membranes.
Question 2 of 5
A nursing manager is concerned about the number of infections on the hospital unit. What action by the manager should reduce the number of infections?
Correct Answer: A
Rationale: All methods will help prevent infection; however, health care workers' lack of hand hygiene is the biggest cause of healthcare-associated infections. The manager can start with a hand hygiene audit to see if this is a contributing cause.
Question 3 of 5
A student nurse asks why brushing clients' teeth with a toothbrush in the intensive care unit is important to reduce the number of infections. The answer is?
Correct Answer: A
Rationale: Biofilms are a complex group of bacteria that function within a slimy gel on surfaces such as teeth. Mechanical disruption (i.e., toothbrushing with friction) is the best way to control them. The other answers are not accurate.
Question 4 of 5
A client is admitted with possible sepsis. Which action should the nurse perform first?
Correct Answer: D
Rationale: Prior to administering antibiotics, the nurse must obtain the ordered cultures. Broad-spectrum antibiotics will be administered until the culture results are available to ensure the infection is appropriately treated.
Question 5 of 5
Which action by the nurse is most helpful to prevent clients from acquiring infections while hospitalized?
Correct Answer: B
Rationale: Consistent practice of proper hand hygiene is the best method to prevent infection, as most healthcare-associated infections are due to staff members' contaminated hands. Assessing the client and monitoring laboratory values will help the nurse catch signs of infection quickly, but will not prevent infection from occurring. Teaching visitors not to visit when they are ill will also help prevent infection, but not to the degree that hand hygiene will.
