A charge nurse is teaching a newly licensed nurse about health care-associated infections (HAIs). Which of the following should the nurse include in the teaching as examples of HAIS?

A client who has pneumonia after being on a ventilator

A client who has a bladder infection and has an indwelling urinary catheter

A client who has a surgical site infection

A client who has influenza acquired from a coworker

A client who has an infection at their central-line insertion site

Answer and Explanation

Correct Answer : A,B,C,E

A.   Ventilator-associated pneumonia (VAP) is a common HAI that occurs in patients who have been mechanically ventilated for an extended period. The presence of a ventilator increases the risk of introducing pathogens into the lower respiratory tract, leading to pneumonia.
B.   Catheter-associated urinary tract infection (CAUTI) is an HAI that occurs due to the use of urinary catheters. Indwelling urinary catheters can introduce bacteria into the urinary tract, increasing the risk of infection.
C.   Surgical site infections (SSIs) are infections that occur after surgery in the part of the body where the surgery took place. They are a significant cause of morbidity and mortality and are considered HAIs when they occur in healthcare settings.
D.   Influenza acquired from a coworker is not typically considered a healthcare-associated infection. It is usually acquired in community settings rather than healthcare facilities.
E.   Central line-associated bloodstream infections (CLABSIs) occur when bacteria or other pathogens enter the bloodstream through a central venous catheter. These infections are considered HAIs because they are associated with the presence of a central venous catheter used for medical treatment.

Correct Answer is C

Explanation

A. An N-95 respirator is designed to filter out airborne particles and is used primarily for protection against airborne diseases such as tuberculosis or certain respiratory infections like COVID-19. It is not necessary for contact precautions unless there is also a risk of airborne transmission.

B. Goggles protect the eyes from splashes, sprays, or droplets of infectious material. They are not typically required for routine contact precautions unless there is a risk of splashes or sprays to the eyes.
C. Gloves are essential for contact precautions. They protect the nurse's hands from direct contact with potentially infectious material on the client's bed linen or any contaminated surfaces. Gloves should be worn when handling soiled linen and removed and discarded appropriately after use.
D. A face shield provides full-face protection against splashes, sprays, or splatters of infectious material. It is particularly useful when there is a risk of exposure to bodily fluids or during procedures that may generate splashes. While not always required for routine contact precautions, it may be used depending on the specific situation, such as when cleaning surfaces heavily contaminated with body fluids.

A. The new mutation spreads easier from one individual to another. B. The new mutation requires a larger amount of the virus to cause disease. C. The new mutation can survive in the environment and retain infectivity. D. The new mutation causes more severe disease.

Correct Answer is A

Explanation

A. Communicability refers to the ability of a pathogen, such as a virus, to spread from one person to another. If a virus undergoes a mutation that increases its communicability, it means that the virus can more readily transmit from an infected person to others. This could be due to changes in viral proteins that enhance attachment to host cells, increase viral shedding, or improve survival in the environment.
B. This statement describes the concept of the infectious dose, not communicability. Infectious dose refers to the amount of virus (or pathogen) required to establish an infection in a susceptible host. A mutation that lowers the infectious dose could potentially increase the likelihood of infection, but it does not directly relate to communicability.

C. Environmental stability refers to the ability of a virus to survive outside of a host and remain capable of causing infection. While environmental stability can contribute to the overall transmission of a virus, it does not specifically define communicability, which focuses on person-to-person spread.
D. Disease severity refers to the impact of infection on the health of an individual, ranging from mild symptoms to severe illness and potential mortality. A mutation that increases disease severity does not necessarily affect communicability unless severe disease leads to behaviors that enhance transmission (e.g., increased shedding of virus).
