A nurse is caring for a client who was just administered hepatitis B immune globulin. The client asks, "How long will it take until I'm protected against hepatitis?" The nurse's response is based on which understanding?

Question

1. It takes several months for the immune system to respond to the antibodies.
2. The client is protected immediately.
3. It is impossible to determine how long it will take, but blood tests will be performed.
4. Active immunity will occur in 10 days to 2 weeks.

Answer 1

Correct Answer: 2
Rationale 1: It does not take several months for the immune system to respond.
Rationale 2: The client will be protected immediately.
Rationale 3: It is established fact that the client is protected immediately.
Rationale 4: Active immunity does not develop.
Global Rationale: Passive immunization is typically used to provide immediate protection against a recent infection, a potential infection, or a disease in progress. The administration of HBIG is effective in the prevention of clinical hepatitis B infection in approximately 75% of individuals who are treated, but this immune protection is temporary, lasting approximately 2 to 3 months.
