Final answer:
The nurse would consider several criteria when determining if an infection is a health care-associated infection (HAI), including whether it originated from an exogenous source, is associated with a medication-resistant microorganism, occurred in conjunction with treatment, and persists despite completing therapy.
Step-by-step explanation:
The nurse would consider several criteria when determining if an infection is a healthcare-associated infection (HAI). These criteria include:
- Originated primarily from an exogenous source: An HAI is an infection that is acquired in a healthcare setting, so the nurse would consider whether the infection was acquired from an external source, such as contaminated equipment or from another patient.
- Is associated with a medication-resistant microorganism: HAIs can be caused by microorganisms that are resistant to common antibiotics, so the nurse would consider whether the infection is caused by a drug-resistant microorganism.
- Occurred in conjunction with treatment for an illness: HAIs often occur in patients who are receiving treatment for another illness or medical condition, so the nurse would consider whether the infection developed while the patient was undergoing treatment.
- Still has the infection despite completing the prescribed therapy: The nurse would also consider whether the patient still has the infection despite completing the prescribed therapy, as this could indicate that the infection is an HAI.
