An organism that is included in the extended-spectrum beta-lactamase-producing pneumonia (ESBL) group is:

Enterococcus.

Escherichia coli.

Staphylococcus aureus.

Clostridium difficile.

Answer and Explanation

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 B

Explanation

Choice A rationale

Stasis ulcers do not specifically predispose older adults to pneumonia and urinary infections. These infections have different primary risk factors and are not directly related to the presence of stasis ulcers.

Choice B rationale

The patient's defenses are already engaged with the initial infection, which can weaken the immune response and make the body more susceptible to additional infections, such as hospital-acquired infections (HAIs).

Choice C rationale

While being bedfast can increase the risk of pressure sores and related infections, it is not directly caused by the presence of a stasis ulcer. The patient's mobility status and overall health condition are more relevant factors.

Choice D rationale

The patient does not have a blood-borne infection. The presence of a stasis ulcer indicates a local infection, not a systemic blood-borne infection.

A. Ask the health care provider whether she contaminated her glove and the sterile field. B. Point out the possible break in surgical asepsis and provide another set of sterile gloves and a fresh sterile field. C. Not say anything, because it is near the end of the procedure. D. Report the health care provider for violating surgical asepsis and endangering the patient.

Correct Answer is B

Explanation

Choice A rationale

Asking the health care provider if they contaminated their glove and the sterile field is not the most effective response. The provider may not be aware of the contamination, and asking this question does not immediately address the contamination issue. Ensuring the sterile field remains uncontaminated is crucial in preventing infections.

Choice B rationale

Pointing out the possible break in surgical asepsis and providing another set of sterile gloves and a fresh sterile field is the best action. This ensures that the sterile environment is maintained, reducing the risk of infection and promoting patient safety.

Choice C rationale

Not saying anything because it is near the end of the procedure is unsafe. Even if the procedure is almost complete, any contamination can increase the risk of infection. It is essential to address the contamination immediately to ensure patient safety.

Choice D rationale

Reporting the health care provider for violating surgical asepsis and endangering the patient is not an immediate solution. While it is important to report such incidents for future prevention, the priority should be to address the contamination promptly to maintain the sterile field and protect the patient.
