Question

question: 9 of 11 pause remaining: 08:20:00 pause flag a nurse is caring for a client who has a health care - associated infection (hai). which of the following describes an exogenous hai? a salmonella infection that occurs after eating contaminated food from the cafeteria an infection that occurs during a therapeutic procedure a yeast infection that occurs while receiving broad spectrum antibiotics a urinary tract infection that occurs after a sterile catheter insertion

Explanation:

To determine an exogenous healthcare - associated infection (HAI), we first recall the definition: an exogenous HAI is caused by microorganisms from outside the client's body.

• Option 1: A Salmonella infection from contaminated cafeteria food comes from an external source (the food), so this is exogenous.
• Option 2: An infection during a therapeutic procedure could be endogenous (from the client's own flora) or exogenous, but this option is too vague and does not clearly indicate an external source.
• Option 3: A yeast infection during broad - spectrum antibiotic use is usually endogenous (overgrowth of the client's own yeast due to disrupted flora), so it is not exogenous.
• Option 4: A urinary tract infection after sterile catheter insertion is often due to endogenous flora (the client's own bacteria introduced during the procedure or from the body's own flora), so it is not exogenous.

Answer:

A. A Salmonella infection that occurs after eating contaminated food from the cafeteria
