Chapter 33. Immunodeficiency1. A nurse in a well-child clinic is teaching parents about their childs immune system.

from foreign substances.
b. The immune system is fully developed by 1 year of age.
c. The immune system protects the child against communicable diseases in the first
6 years of life.
d. The immune system responds to an offending agent by producing
antigens. ANS: A
The immune system responds to foreign substances, or antigens, by producing
antibodies and storing information. Intact skin, mucous membranes, and
processes such as coughing, sneezing, and tearing help maintain internal
homeostasis. Children up to the age of 6 or 7 years have limited antibodies
against common bacteria. The immunoglobins reach adult levels at different
ages. Immunization is the basis from which the immune system activates protection against
some communicable diseases. Antibodies are produced by the immune system against invading
agents, or antigens.

immaturity of the immune system. The parents demonstrate that they understand the teaching
if they make which statement?
a. The spleen reaches full size by 1 year of
age. b. IgM, IgE, and IgD levels are high at
birth.
c. IgG levels in the newborn infant are low at birth.
d. Absolute lymphocyte counts reach a peak during the first year.
, ANS: D
Absolute lymphocyte counts reach a peak during the first year. The spleen reaches its full size
during adulthood. IgM, IgE, and IgD are normally in low concentration at birth. IgM, IgE,
IgA, and IgD do not cross the placenta. The term newborn infant receives an adult level of
IgG as a result of transplacental transfer from the mother.
3. Which statement is true regarding how infants acquire immunity?
a. The infant acquires humoral and cell-mediated immunity in response to
infections and immunizations.
b. The infant acquires maternal antibodies that ensure immunity up to 12 months
of age.
