Anatomy & Physiology Immune #5

Question

A client has a history of rubella infection with laboratory verification of antibodies. Which is the best type of immunity for the nurse to document in this client’s medical record based on the current data?

Answers

  1. Active
    • Rationale:

      Active immunity results from the production of immune system antibodies in response to the presence of an antigen. It is verified via laboratory testing.

  2. Innate
    • Rationale:

      Innate (i.e., natural) immunity does not require previous sensitization to an antigen. The skin is a structure that provides the human body with natural immunity.

  3. Passive
    • Rationale:

      Passive immunity occurs when a person gets antibodies with an immunoglobulin of antibodies. In addition, passive immunity is transferred from a mother to a fetus in utero; it is a short lived, or temporary, form of immunity.

  4. Natural
    • Rationale:

      Natural (i.e., innate) immunity does not require previous sensitization to an antigen. The skin is a structure that provides the human body with natural immunity.

Overview

Immunity is defined as the ability of an organism to resist particular infections or toxins via specific antibodies or white blood cells that are sensitized.

Explanation

Learning Outcomes

There are four basic types of immunity within the human body. These types of immunity include active immunity, artificial immunity, natural immunity, and passive immunity. Active immunity occurs when an individual produces antibodies against a pathogen and it is verified by laboratory testing. An example of active immunity is verifying the presence of antibodies to rubella via laboratory testing.

Test Taking Tip

Consider the definition of each type of immunity when determining the correct choice for this question.
