What is the name of a severe allergic reaction?

A. This fever could cause a seizure:

Febrile seizures are typically associated with temperatures >102°F, especially when rising rapidly.

B. A low-grade temperature can decrease multiplication of pathogens:

A mild fever is a normal immune response that creates an environment less favorable for pathogens to multiply and can enhance immune activity.

C. The child should be taking fever reducing medicine:

Antipyretics may not be necessary for a low-grade fever unless the child is uncomfortable.

D. This is serious, they need to see the doctor right away:

A temperature of 100.3°F is considered low-grade and generally not serious in an otherwise healthy child.

A. Naturally acquired passive immunity

Passive immunity occurs when antibodies are transferred (e.g., from mother to baby); it does not involve the person’s immune system actively responding.

B. Naturally acquired active immunity

This occurs when a person is exposed to a pathogen, like the measles virus, and their body mounts an immune response, producing long-lasting immunity.

C. Artificially acquired active immunity

This is obtained through vaccination, not from infection.

D. Artificially acquired passive immunity

This refers to receiving antibodies (e.g., through injection of immune globulin), not through natural infection.
