Exam 13: Host Defenses II: Specific Immunity and Immunization

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 of the following explanations tells you why Joseph became infected with chickenpox in the first place?

T-cell response to T-cell-Dependent antigens requires

Killed or inactivated vaccines are prepared by

Antibody molecules circulate in lymph,blood,and tissue fluids.

Clonal selection can be stimulated by foreign or self antigens.

Each _____ fragment of an antibody molecule contains the variable regions of a heavy and light chain that folds into a groove for one epitope.

The progeny cells of a B-cell clone are called

Cytotoxic T cells

Acquired specific immunity involves the response of

Which lymphocytes lack specificity for antigen and are cells that attack cancer cells and virus-infected cells?

An example of natural passive immunity would be

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. Marie is a 57-year-old female who is on your general medical-surgical unit with a bladder infection. Two weeks ago, she was having slight burning upon urination. She self-treated with an increased intake of cranberry juice, but did not see any improvement. In fact, her symptoms got worse. Last week, she developed generalized abdominal pain and a mid-grade fever. She did not come into the hospital until the pain was unbearable and she had a fever of 104F. She was admitted to your unit and started on multiple IV antibiotics. The doctors say that she could be developing a kidney infection. -Knowing that Marie's primary organism causing her UTI is

Which process involves antibodies covering surface receptors on a virus or toxin molecule thereby disrupting their activity?

The beauty of specific immunity is the production of ____ that provide long-lasting protection.

A foreign molecule that causes a specific immune response is a(n)

Activation of B cells occurs when antigen binds to B-cell surface immunoglobulin receptors.

During which response to the antigen do we display a latent period of no secretory antibody synthesis?
