The nurse performing a surgical scrub is aware that the average time for the scrub is:

Choice A rationale

While immune globulin can be given to non-immune individuals exposed to chickenpox, the baby already has some protection because the mother has naturally acquired immunity. Hence, giving immune globulin is not necessary in this case.

Choice B rationale

Although the infant has not been immunized against chickenpox, the baby still receives passive immunity through the mother's breast milk. The antibodies transferred via breastfeeding provide some level of protection to the baby.

Choice C rationale

The mother's immunity against chickenpox, acquired from a past infection, remains effective throughout her life. This immunity is transferred to the baby through the placenta during pregnancy and continues through breastfeeding, providing protection to the infant.

Choice D rationale

The mother’s naturally acquired immunity from her childhood infection provides antibodies against chickenpox that she passes on to the baby through the breast milk. This passive immunity helps protect the baby from the infection.

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.
