Chapter 16 Questions
Question 1 of 5
Chickenpox is an example of which of the following types of immunities?
Correct Answer: B
Rationale: Chickenpox is an example of natural active immunity, as it is acquired through natural exposure to the varicella-zoster virus, leading to the production of antibodies and memory cells.
Question 2 of 5
The nurse is caring for a patient in the outpatient clinic who has an immune deficiency involving the T-lymphocytes. Which of the following areas should the nurse teach the patient about the need for more frequent screening?
Correct Answer: B
Rationale: Cell-mediated immunity is responsible for the recognition and destruction of cancer cells. Allergic reactions, autoimmune disorders, and antibody deficiencies are mediated primarily by humoral immunity.
Question 3 of 5
Which of the following antibodies is involved with an anaphylactic reaction?
Correct Answer: A
Rationale: Serum IgE causes the symptoms of allergic reactions and is the antibody involved with an anaphylactic reaction.
Question 4 of 5
The nurse encourages a new mother to breastfeed her infant, even for a short time, because colostrum will provide the infant with which of the following types of immunity?
Correct Answer: C
Rationale: Colostrum provides passive immunity through antibodies from the mother; these antibodies protect the infant for a few months. However, memory cells are not retained, so the protection is not permanent. Innate immunity is present at birth and occurs without exposure to an antigen. Active immunity requires that the infant manufacture antibodies after exposure to an antigen. Cell-mediated immunity is acquired through T-lymphocytes and is a form of active immunity.
Question 5 of 5
The nurse is assessing a patient for possible atopic dermatitis. Which of the following laboratory values should the nurse review?
Correct Answer: A
Rationale: Serum IgE causes the symptoms of allergic reactions and is elevated in type 1 hypersensitivity disorders. The eosinophil level will be elevated, rather than neutrophil or basophil counts. IgA is located in body secretions and would not be tested when evaluating a patient who has symptoms of atopic dermatitis.
