Which infectious disease interferes with the human immune system, leaving the body open to opportunistic infections?
HIV
Tuberculosis
Candidiasis
MRSA
The Correct Answer is A
HIV stands for human immunodeficiency virus, a virus that infects and destroys CD4+ T cells, which are a type of white blood cell that coordinates the immune response against foreign invaders. HIV can cause acquired immunodeficiency syndrome (AIDS), which is a condition where the immune system becomes severely weakened and unable to fight off common infections and cancers. HIV can be transmitted through sexual contact, blood transfusion, needle sharing, or mother-to-child transmission.

The symptoms of pericarditis may include chest pain that worsens with breathing or lying down, shortness of breath, fever, chills, sweating, or low blood pressure.
Correct Answer is A
Explanation
Cushing syndrome is a condition that occurs when the body is exposed to high levels of cortisol, a hormone produced by the adrenal glands. Cortisol helps regulate metabolism, blood pressure, immune function, and stress response.
However, excess cortisol can cause various problems, such as weight gain, moon face (round and puffy face), buffalo hump (fat accumulation on the upper back), purple striae (stretch marks), irregular periods, weakness, emotional changes, and easy bruising. One of the causes of Cushing syndrome is the overproduction of ACTH by the pituitary gland, which stimulates the adrenal glands to produce more cortisol.
