Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format.
Joseph is a 6-year-old male presenting to your pediatric office with chickenpox. He has had his infection for about 1 week, and his mom is concerned about Joseph’s 8-year-old sister, Judith, because she had a long, painful infection of chickenpox 2 years before. Of note, Joseph was not vaccinated against chickenpox when he was younger, because his mom did not think it was that serious of a virus, and she wanted to spare him the extra injection.
-Which cells will keep Joseph from becoming infected again?

T memory cells are responsible for storing memories of previous infections and are able to recognize and respond more quickly to the same pathogen if it enters the body again. This means that Joseph's T memory cells, which were generated during his current chickenpox infection, will protect him from becoming infected with chickenpox again in the future. Choice A (T helper cells) and choice D (B cells) are both involved in the immune response, but they are not directly responsible for providing long-term protection against a specific pathogen. Choice B (natural killer cells) are important for killing infected or cancerous cells, but they do not provide specific protection against a particular infection.
