An organism that is included in the extended-spectrum beta-lactamase-producing pneumonia (ESBL) group is:
Enterococcus.
Escherichia coli.
Staphylococcus aureus.
Clostridium difficile.
The Correct Answer is B
Choice A rationale
Enterococcus species are not typically associated with extended-spectrum beta-lactamase (ESBL) production. These bacteria are more commonly known for their resistance to other classes of antibiotics, like vancomycin.
Choice B rationale
Escherichia coli (E. coli) is a common bacterium that can produce extended-spectrum beta-lactamases (ESBLs), which confer resistance to a wide range of beta-lactam antibiotics, including penicillins and cephalosporins.
Choice C rationale
Staphylococcus aureus is not part of the ESBL-producing group. It is more commonly associated with methicillin-resistant Staphylococcus aureus (MRSA) and is resistant to beta-lactam antibiotics through different mechanisms.
Choice D rationale
Clostridium difficile is not associated with ESBL production. It causes infections through the release of toxins that lead to severe gastrointestinal symptoms, rather than through beta-lactamase production.

Correct Answer is A
Explanation
Choice A rationale
Wearing gloves and a gown when bathing a client who has open skin lesions is important to prevent the transmission of infectious agents and protect both the client and the caregiver. Open lesions are potential entry points for pathogens.
Choice B rationale
While wearing gloves when measuring blood pressure might seem like a precaution, it is unnecessary unless there is an anticipated exposure to blood or bodily fluids. Gloves are not routinely needed for measuring BP in non-infectious cases.
Choice C rationale
Using gloves to reduce the number of hand washes is not appropriate. Gloves should be worn to prevent contamination and infection, not to replace hand hygiene practices. Hand hygiene should still be performed before and after glove use.
Choice D rationale
Wearing gloves whenever in contact with clients may not be necessary for all interactions. Gloves should be worn based on the anticipated exposure to infectious materials, not indiscriminately, to avoid waste and maintain proper infection control.
Correct Answer is D
Explanation
Choice A rationale
Covering the patient with a clean sheet helps in preventing contamination during transport, but it is not the most critical action to prevent droplet transmission.
Choice B rationale
Wearing a gown and gloves is important for contact precautions, but droplet precautions specifically require protection from respiratory droplets.
Choice C rationale
Wearing the appropriate respiratory device is important in airborne precautions, but droplet precautions primarily require mask use.
Choice D rationale
Wearing a mask within 3 feet of the patient is crucial for droplet precautions to prevent the spread of respiratory droplets from the infected patient.
