The nurse instructing a patient in the home use of disinfectant would include the information that the disinfectant can be used to:

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

Requiring the use of a facemask by nursing staff is not sufficient alone as a nursing intervention for a surgical incision and IV line access. Comprehensive infection control measures are needed.

Choice B rationale

Maintaining "clean" technique is important, but "sterile" technique would be more appropriate for wound dressing changes and IV site care to prevent infection.

Choice C rationale

Assessing and documenting skin condition around the incision and IV site at each shift is correct because it helps in early identification of signs of infection, ensuring timely intervention.

Choice D rationale

Limiting visitors to immediate family may help reduce infection exposure, but it does not address the primary nursing intervention for monitoring and caring for the surgical incision and IV site.
