The nurse explains to the patient who has pneumococcal pneumonia that the lungs serve as the:

Organisms that cause the infection.

Transmission of the disease.

Mode of transfer.

Reservoir.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Organisms that cause the infection refer to the pathogens such as bacteria, viruses, or fungi. In the context of pneumococcal pneumonia, the organism is Streptococcus pneumoniae. The lungs do not serve as the organisms; they are the site of infection.

Choice B rationale

Transmission of the disease involves the spread of pathogens from one individual to another. Pneumococcal pneumonia is transmitted via respiratory droplets, not the lungs serving as the transmission medium.

Choice C rationale

Mode of transfer refers to the mechanisms by which an infection spreads, such as direct contact, airborne, or vector-borne. The lungs are not a mode of transfer; they are the site of infection.

Choice D rationale

Reservoirs are places where pathogens live, grow, and multiply. In the case of pneumococcal pneumonia, the lungs act as a reservoir where the bacteria can grow and cause infection.

Correct Answer is B

Explanation

Choice A rationale

Using gowns, gloves, and masks for any family contact with the patient is more stringent than necessary for home care. It would not be practical or necessary for family members and may create unnecessary barriers.

Choice B rationale

Maintaining medical asepsis and proper handling of contaminated dressings is essential to prevent the spread of infection. This involves proper hand hygiene, using clean dressings, and disposing of contaminated materials correctly.

Choice C rationale

Washing hands thoroughly before the dressing change is crucial but not enough on its own to prevent the spread of infection. It must be combined with other aseptic techniques.

Choice D rationale

Having the patient be the only person to perform dressing changes does not eliminate the risk of infection to family members, as they may still come into contact with contaminated materials.

A. Enterococcus. B. Escherichia coli. C. Staphylococcus aureus. D. Clostridium difficile.

Correct Answer is B

Explanation

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.
