A patient's chart shows a blood pressure of 190/137, with a usual blood pressure of 170/110.

What is a possible diagnosis?

Hypotensive crisis

Hypertensive crisis

Stage 2 hypertension

Stage 1 hypertension

Answer and Explanation

The Correct Answer is B

A hypertensive crisis is defined as a systolic blood pressure (top number) of 180 mm Hg or higher or a diastolic blood pressure (bottom number) of 120 mm Hg or higher. A patient with a blood pressure of 190/137 meets this criterion and has a significantly elevated risk of organ damage and cardiovascular complications. A usual blood pressure of 170/110 indicates that the patient has chronic hypertension, which is a risk factor for hypertensive crisis.

Correct Answer is A

Explanation

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.

A. Lower number of complement proteins B. Decreased populations of naïve T cells C. Impaired primary defenses D. Insufficient time outdoors

Correct Answer is B

Explanation

Naïve T cells are a type of white blood cell that has not encountered a specific antigen before and are ready to respond to new infections. As people age, the number of naïve T cells decreases due to the shrinking of the thymus gland, which produces and matures T cells. This reduces the ability of the immune system to recognize and fight new pathogens and lowers the effectiveness of vaccines.
