Question

before. When should the nurse instruct the caregivers to return for this vaccine for this
child?
A. after 1 to 2 weeks
B. after 3 to 4 weeks
C. after 6 to 8 weeks
D. after 4 to 5 weeks

Answer 1

The nurse should instruct the caregivers to return for the child's MMR vaccine after 3 to 4 weeks following an antivenin injection, to ensure the vaccine is effective. The Correct Answer is Option. B.

Step-by-step explanation:

The recommended time to administer the MMR (measles, mumps, and rubella) vaccination after receiving an antivenin injection for a snake bite is after 3 to 4 weeks.

This waiting period allows for the antivenin antibodies to decrease in the body so they won't interfere with the vaccine's effectiveness.

Antivenin can potentially contain significant amounts of immunoglobulins which can interfere with the live vaccine if administered too soon after the antivenin injection.

Therefore, the nurse should instruct the caregivers to return for the child's MMR vaccine B. after 3 to 4 weeks.
