The nurse clarifies that the difference between the use of earlier types of isolation procedures and the use of current Standard Procedures plus Transmission-Based Precautions as outlined by the CDC:

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.

Choice A rationale

Filling linen bags with as much soiled linen as possible can cause the bags to be too heavy, increasing the risk of tearing and contamination. Overfilled bags are also harder to handle safely.

Choice B rationale

Returning unused fresh linen to the supply area can lead to contamination of clean supplies. It's recommended to avoid reusing linen that has been in a patient's room to maintain hygiene.

Choice C rationale

Double bagging is not a necessary practice for soiled linen unless the outside of the first bag becomes contaminated. It's more important to handle the bags properly.

Choice D rationale

Tying linen bags securely at the top helps to contain the soiled linens and prevents contamination and the spread of infections. Secure closure ensures that the contents remain contained during transport.
