Chapter 33 : Introduction to the Immune System Questions
Question 1 of 5
A parent of a child who has been having frequent bouts of tonsillitis brings the child back to the clinic for another sore throat. The parent asks the nurse, 'What are tonsils good for anyway?' What is the best response by the nurse?
Correct Answer: B
Rationale:
Tonsils and adenoids filter bacteria from tissue fluid. Because they are exposed to pathogens in the oral cavity, they can become infected and locally inflamed. The spleen acts as an emergency reservoir of blood and removes blood and bacteria, not the tonsils.
Question 2 of 5
A client with chronic renal failure has begun treatment with a colony-stimulating factor. What medication does the nurse anticipate administering to the client that will promote the production of blood cells?
Correct Answer: C
Rationale: Colony-stimulating factors are cytokines that prompt the bone marrow to produce, mature, and promote the functions of blood cells. CSFs enable stem cells in bone marrow to differentiate into specific types of cells such as leukocytes, erythrocytes, and platelets. Pharmacologic preparation of CSFs, such as epoetin alfa (Epogen), is used to promote the natural production of blood cells in people whose own hematopoietic functions have become compromised. The other medications are tumor necrosis factor inhibitors.
Question 3 of 5
A laboring mother asks the nurse if the baby will have immunity to some illnesses when born. What type of immunity does the nurse understand that the newborn will have?
Correct Answer: C
Rationale: Passive immunity develops when ready-made antibodies are given to a susceptible person. The antibodies provide immediate but short-lived protection from the invading antigen. Newborns receive passive immunity to some diseases for which their mothers have manufactured antibodies. Naturally acquired active immunity occurs as a direct result of infection by a specific microorganism. An example is the immunity to measles that develops after the initial infection. Not all invading microorganisms produce a response that gives lifelong immunity. Artificially acquired immunity is obtained by receiving a killed or weakened microorganism or toxoid.
Question 4 of 5
A client will be receiving a hepatitis B vaccination series prior to employment in a dialysis center. What type of immunity will this provide?
Correct Answer: D
Rationale: Artificially acquired immunity is obtained by receiving a killed or weakened microorganism or toxoid. Passive immunity develops when ready-made antibodies are given to a susceptible person. The antibodies provide immediate but short-lived protection from the invading antigen. Newborns receive passive immunity to some diseases for which their mothers have manufactured antibodies. Naturally acquired active immunity occurs as a direct result of infection by a specific microorganism. An example is the immunity to measles that develops after the initial infection. Not all invading microorganisms produce a response that gives lifelong immunity. There is not a type of immunity called forced immunity.
Question 5 of 5
The nurse is beginning the physical examination of a client who has reported fatigue. What documentation will the nurse provide to describe this general appraisal of the client's health?
Correct Answer: A
Rationale: The beginning of the physical examination is a general appraisal of the client's health. The nurse notes whether the client appears healthy, acutely or mildly ill, malnourished, extremely tired, or listless. The next thing the nurse will do is obtain vital signs and then perform a more comprehensive examination.
