Which stage of the human immunodeficiency virus (HIV) would a client with a CD4 T cell count of 325 cells/mm3 be classified

kirza4 [7]

Based on the CDC guidelines a person with a CD4+ cell count between 200-400 is regarded as being in <u>the second stage</u> of the HIV infection.

Acquired Immunodeficiency Syndrome

Acquired immunodeficiency syndrome (AIDS) is a condition caused by HIV (human immunodeficiency virus). AIDS is a chronic disorder and can become life-threatening for the infected person. The HIV viruses reproduce inside the host and while doing so they destroy the CD4+ immune cells which reduce the person's ability to fight against other diseases.

CD4+ cell count and AIDS

According to the CDC (U.S. Centers for Disease Control and Prevention), HIV infection is categorized into different stages based on the number of CD4+ cells.

Stage 1: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
Stage 2: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
Stage 3: - The CD4+ cell count falls below 200 and AIDS-related symptoms and conditions are present.

Receptors that are especially important for helping a person maintain balance are located in the (A) gyrus cinguli (B) inner ear

Lera25 [3.4K]

The receptors that aid in allowing a person to maintain balance are located within the inner ear.

The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.

The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.
