A client asks, "Why do we get some diseases, like chickenpox, only once, but I get a cold several times a year?" What is the nurse's best response?
1. "The immune system develops a memory for chickenpox, or varicella, but not for colds."
2. "Chickenpox, or varicella, is caused by one virus, while colds are caused by many different viruses."
3. "So many people are immunized against varicella that exposure is rare."
4. "Some people do get varicella more than once."

Rationale 1: Memory cells are produced for infections.
Rationale 2: Varicella is caused by one virus. Colds are caused by many viruses that readily mutate.
Rationale 3: There are many people who are not immunized against varicella. The rate of exposure is not the reason for this phenomenon.
Rationale 4: Having a true case of varicella more than once is rare and would occur only if the initial case was so mild that memory cells did not develop. This response does not address the client's question adequately.
