question 14
1 pts
when a patient asks the nurse what hypersensitivity is, how should the nurse respond? hypersensitivity is best defined as:
a reduced immune response found in most pathologic states.
a normal immune response to an infectious agent.
an excessive or inappropriate response of the immune system to a sensitizing antigen.
antigenic desensitization.

Explanation:

Question 13

Hemolytic disease of the newborn (HDN) occurs when an Rh - negative mother has an Rh - positive fetus. The mother's immune system may produce antibodies against the Rh factor of the fetus, leading to hemolysis in the infant. Exposure to measles (option 1) and Agent Orange (option 2) are not related to HDN. Premature birth (option 4) is not a direct cause of HDN. So the relevant factor in the infant's history/physical is the baby being Rh positive.

Hypersensitivity is not a reduced immune response (that's immunodeficiency, so option 1 is wrong), not a normal immune response to an infectious agent (option 2 is wrong), and not antigenic desensitization (option 4 is wrong). Hypersensitivity is defined as an excessive or inappropriate response of the immune system to a sensitizing antigen.

Answer:

The baby is Rh positive.
