c diff
mrsa
vre
cre

1. what organism is found in freshwater habitats and can infect a person if they inhale mist or droplets?

c diff
hepatitis
influenza
legionella

1. which of the following is an appropriate guideline to follow when using personal protective equipment, or ppe?

wash your ppe after each use and perform hand hygiene.
change ppe and perform hand hygiene before providing care to another person.
use gloves as a substitute for performing hand hygiene.
perform hand hygiene but reuse your ppe.

Explanation:

1. CRE (Carbapenem - resistant Enterobacteriaceae) are highly resistant to most antibiotics and can cause high death - rates. C diff (Clostridioides difficile) is a major cause of healthcare - associated diarrhea, MRSA (Methicillin - resistant Staphylococcus aureus) is resistant to beta - lactam antibiotics but not as resistant as CRE in general, and VRE (Vancomycin - resistant Enterococcus) is resistant to vancomycin but not as life - threatening as CRE in terms of overall mortality related to antibiotic resistance.
2. Legionella is found in freshwater habitats and can cause Legionnaires' disease when people inhale mist or droplets containing the bacteria. C diff is not typically associated with freshwater inhalation, hepatitis is a virus usually transmitted through blood or body fluids, and influenza is an airborne virus not typically associated with freshwater habitats in this context.
3. When using PPE, it is appropriate to change PPE and perform hand hygiene before providing care to another person to prevent cross - contamination. Washing PPE after each use may not be practical in all situations, gloves are not a substitute for hand hygiene, and reusing PPE without proper decontamination can lead to infection spread.

Answer:

1. D. CRE
2. D. Legionella
3. B. Change PPE and perform hand hygiene before providing care to another person
