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

Breaking needles in half before disposal is dangerous and not recommended. It increases the risk of needlestick injuries and exposure to bloodborne pathogens.

Choice B rationale

Not recapping needles, especially after drawing arterial blood gas (ABG) specimens, is a recommended practice to prevent needlestick injuries. This reduces the risk of accidental puncture during the recapping process.

Choice C rationale

Recapping needles and placing them in a wastebasket is unsafe and increases the risk of needlestick injuries and improper disposal of medical waste, which can expose others to bloodborne pathogens.

Choice D rationale

Placing uncapped needles directly into a puncture-proof container after use is a safe practice, but the question specifically asks about preventing needlestick injuries during the handling of ABG specimens, where recapping should be avoided.

A. Throw the needle and syringe immediately in a covered garbage can with a red plastic liner to indicate the materials are biohazards. B. Recap the needle and place it carefully on the patient's table until leaving the room, then discard it in a garbage container in the nurses' medication room. C. Carefully break the needle from the syringe, using the needle cover to prevent reuse of a used syringe and needle. D. Never recap the needle afterward to avoid risk of needle stick.

Correct Answer is D

Explanation

Choice A rationale

Throwing the needle and syringe immediately into a garbage can, even if covered and lined, does not ensure proper disposal of biohazard materials. This practice increases the risk of contamination and injury.

Choice B rationale

Recapping the needle and placing it on the patient's table until leaving the room increases the risk of needle stick injuries and improper disposal, which is unsafe and against best practices for needle safety.

Choice C rationale

Breaking the needle from the syringe using the needle cover to prevent reuse does not eliminate the risk of needle stick injuries and may lead to improper disposal and handling of biohazard materials.

Choice D rationale

Never recapping the needle afterward is the safest practice to avoid the risk of needle stick injuries, as recapping is a common cause of such injuries. Proper disposal in a sharps container immediately after use is the recommended method.
