Which term means condition of nitrogen in the blood?

• A. Axillary
• B. Azotemia
• C. Autoimmunity
• D. Bactericide

Answer: (B)

Azotemia is the term for a condition involving nitrogenous waste in the blood. The root azot- means nitrogen, and -emia means a blood condition, so together they describe elevated nitrogenous wastes like urea and creatinine in the bloodstream. This typically happens when the kidneys aren’t filtering properly, with variations depending on where the problem lies (pre-renal, renal, or post-renal). The other terms don’t relate to nitrogen in the blood: axillary refers to the armpit, autoimmunity to immune reactions against the body's own tissues, and bactericide to something that kills bacteria.
