If a person had measles as a child, which of the following best describes their immunity to measles?

A. Advising the patient to avoid all physical activity to prevent strain:

Complete avoidance of activity can lead to stiffness and muscle atrophy. Gentle activity is encouraged.

B. Encouraging the use of compression garments on the affected arm:

Compression garments help prevent or reduce lymphedema by promoting lymph drainage in the affected arm.

C. Instructing the patient to apply heat to the affected arm to reduce swelling:

Heat can exacerbate swelling and inflammation and should be avoided.

D. Recommending the patient to keep the arm elevated at all times:

While occasional elevation may help, constant elevation is impractical and unnecessary. It is not the primary prevention strategy.

A. Spleen:

The spleen filters blood and helps initiate immune responses, but it does not mature T cells.

B. Thymus gland:

The thymus is the primary site where immature T lymphocytes mature and become functional.

C. Tonsils:

Tonsils help detect pathogens entering through the mouth or nose but are not involved in T cell maturation.

D. Pancreas:

The pancreas is involved in digestion and blood glucose regulation, not immune cell development.
