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
Gloves should be removed before other PPE to prevent contamination from potentially dirty gloves. However, they are not the last piece to be removed.
Choice B rationale
Gowns should be removed after gloves to avoid contaminating the clothing and skin. However, the mask, which prevents inhalation of contaminants, should be the last to be removed.
Choice C rationale
Eyewear should be removed before the mask to prevent contamination from the hands. However, they are not the last piece to be removed.
Choice D rationale
The mask should be removed last to ensure that the respiratory system is protected until all other contaminated PPE has been removed. This helps reduce the risk of inhaling any remaining airborne contaminants.
