When the nurse is using a syringe and needle to give a patient an injection, he or she should:

Throw the needle and syringe immediately in a covered garbage can with a red plastic liner to indicate the materials are biohazards.

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.

Carefully break the needle from the syringe, using the needle cover to prevent reuse of a used syringe and needle.

Never recap the needle afterward to avoid risk of needle stick.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Throwing the needle and syringe immediately into a covered garbage can with a red plastic liner is not the safest disposal method for biohazard materials. It does not prevent needle stick injuries effectively.

Choice B rationale

Recapping the needle and placing it on the patient's table until leaving the room is not a safe practice. It increases the risk of needle stick injuries and potential exposure to contaminated materials.

Choice C rationale

Breaking the needle from the syringe using the needle cover to prevent reuse does not ensure complete safety. It can still lead to needle stick injuries and improper handling of biohazard materials.

Choice D rationale

Never recapping the needle afterward is the safest approach. It minimizes the risk of needle stick injuries and ensures proper disposal in designated sharps containers immediately after use.

Correct Answer is D

Explanation

Choice A rationale

Washing hands when visibly soiled removes dirt, debris, and pathogens, effectively reducing the risk of infection.

Choice B rationale

Washing hands after using the restroom is a critical practice to prevent the spread of gastrointestinal pathogens.

Choice C rationale

Washing hands before meal preparation prevents the transmission of pathogens to food, protecting against foodborne illnesses.

Choice D rationale

Hands that appear clean may still harbor pathogens. Effective hand hygiene includes washing hands for at least 20 seconds with soap and water to remove invisible pathogens. .

A. Stimulate the production of interferons. B. Engulf and destroy the pathogen. C. Create antibodies against the pathogen. D. Stimulate the body to make more white blood cells.

Correct Answer is B

Explanation

Choice A rationale

Interferons are proteins produced by cells in response to viral infections and are part of the body's immune response, but they are not directly involved in the engulfing of pathogens.

Choice B rationale

Phagocytosis is the process by which certain cells, such as macrophages and neutrophils, engulf and destroy pathogens. This is a crucial mechanism of the innate immune system.

Choice C rationale

Creating antibodies is the function of B cells in the adaptive immune system, which works alongside phagocytosis but is not the same process.

Choice D rationale

Phagocytosis itself does not stimulate the body to make more white blood cells, but it is a function performed by existing white blood cells to eliminate pathogens.
