Chapter 33: Immune System
The anatomy and physiology instructor is explaining a cell-mediated response to the pre-nursing students. What actions would the instructor explain occur in a cell-mediated response?
T-cell lymphocytes survey proteins in the body and attack the invading antigens.
You are caring for a client on tube feedings. The physician has ordered Osmolite HN as the feeding formula for the client. The family asks why the physician has ordered Osmolite HN instead of another formula to feed their family member. What is an important reason that tube-feeding formulas, such as Impact, Osmolite HN, or Perative, be recommended to clients?
To enhance the production of lymphocytes and NK cells
A client is informed that his white blood cell count is low and that he is at risk for the development of infections. The client asks, "Where do I make new white blood cells?" What is the best response by the nurse?
"White blood cells are produced in the bone marrow."
A 15-year-old client has been brought to the clinic by his mother and is suspected of having an immune system disorder. What tests would you expect to be ordered for this young client?
Complete blood count with differential
A client's immune system has the ability to protect itself from external invaders. What type of immune function is present when this occurs?
Immunocompetence
When an attenuated toxin is administered to a client, the B lymphocytes create memory cells that recognize the antigen if it invades the body at a future time. What kind of immunity is this?
Artificially acquired active immunity
The nursing students are learning about the immune system in their anatomy and physiology class. What would these students learn is a component of the immune system?
Lymphoid tissues
A child is brought to the clinic with a rash. The child is diagnosed with measles. The mother tells the nurse that she had the measles when she was a little girl. What immunity to measles develops after the initial infection?
Naturally acquired active immunity
You are the clinic nurse caring for a client with a suspected diagnosis of HIV. You are preparing to draw blood for a confirmatory diagnostic test on this client. What is the most important action that the nurse should perform before testing a client for HIV?
Obtain a written consent from the client.
What is the function of the thymus gland?
Programs T lymphocytes to become regulator or effector T cells
You are caring for a client with a suspected immune system disorder. What test would be ordered if a deficiency or excess of immunoglobulins was suspected?
Protein electrophoresis
A 64-year-old male client, who leads a sedentary lifestyle, and a 31-year-old female client, who has a very stressful and active lifestyle, require a vaccine against a particular viral disorder. As the nurse, you would know that in one of these clients, the vaccine will be less effective. In which client is the vaccine more likely to be less effective and why?
The male client because of his age
