A client will be receiving a hepatitis B vaccination series prior to employment in a dialysis center. What type of immunity will this provide?
- A. Forced immunity
- B. Naturally acquired active immunity
- C. Passive immunity
- D. Artificially acquired active immunity
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.

The nurse is caring for a client with a suspected immune system disorder. What test would be ordered if a deficiency or excess of immunoglobulins was suspected?
- A. Protein electrophoresis
- B. Enzyme-linked immunosorbent assay
- C. T-cell and B-cell assays
- D. Plasmapheresis
Correct Answer: A
Rationale: When an immune system disorder is suspected, protein electrophoresis screens for diseases associated with a deficiency or excess of immunoglobulins may be ordered. The other options are incorrect tests to diagnose a deficiency or excess of immunoglobulins.
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?
- A. Naturally acquired active immunity
- B. Artificially acquired active immunity
- C. Passive immunity transferred by the mother
- D. There is no immunity passed down from mother to child.
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.
A client is informed of having a low white blood cell count and being 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?
- A. White blood cells are produced in the plasma.
- B. White blood cells are produced in the thymus gland.
- C. White blood cells are produced in the lymphatic tissue.
- D. White blood cells are produced in the bone marrow.
Correct Answer: D
Rationale: White blood cells (leukocytes) are produced in the bone marrow. They are not produced in the plasma, thymus gland, or the lymphatic tissue.
Why would it be important for the nurse to question the client about sexual practices, history of substance use disorder, and lifestyle during the interview process?
- A. To find out if the client will be compliant with therapeutic treatments
- B. To determine if the client has practices that are risk factors for acquired immunodeficiency syndrome (AIDS)
- C. To determine if the client needs a referral to counseling services
- D. To determine what type of personality the client has
Correct Answer: B
Rationale: The nurse investigates the client's allergy history and asks about practices that put the client at risk for AIDS. The interview will not determine the client's ability to be compliant. The physician would make the determination if a counseling referral should be made. It is irrelevant to determine the personality traits in the initial interview.
A client's immune system has the ability to protect itself from external invaders. What type of immune function is present when this occurs?
- A. Immunosuppression
- B. Immunocompetence
- C. An immune response
- D. Immune incompatibility
Correct Answer: B
Rationale: The immune system is a collection of specialized white blood cells and lymphoid tissues that maintain immunocompetence, the ability to cooperatively protect a person from external invaders and the body's own altered cells. Immunosuppression is the opposite and the white blood cells and lymphoid tissue are not able to protect a person from external invaders. An immune response, primarily involves the lymphocytes that are located in blood and lymphoid tissue. Immune incompatibility is not relevant in this situation.
