A patient has been diagnosed with Creutzfeldt-Jakob disease (mad cow disease). The nurse recognizes this disease is caused by a:

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.

Choice A rationale

While it is true that Standard Precautions apply to patients with draining wounds, these precautions are not limited to such scenarios. They are a broader set of practices.

Choice B rationale

Standard Precautions do help prevent the transmission of respiratory and wound infections, but their application is universal, not limited to these conditions.

Choice C rationale

Standard Precautions are designed to be used when caring for all patients, regardless of their diagnosis or infection status, to prevent the spread of infections.

Choice D rationale

Standard Precautions are used routinely with all patients, not only when there is a suspicion or risk of infection. This universal approach helps ensure a high level of infection control.
