Which condition is characterized by insufficient function or number of red blood cells?

• A. Anemia
• B. Alcoholic dementia
• C. Korsakoff's psychosis
• D. Blackout

Answer: (A)

Anemia occurs when the blood doesn’t have enough healthy red blood cells or enough hemoglobin to carry adequate oxygen to the body’s tissues. With fewer functioning red blood cells, organs don’t get the oxygen they need, leading to fatigue, weakness, pale skin, shortness of breath, and dizziness. Anemia can result from not making enough red blood cells, losing them faster than they’re made (as with bleeding), or red blood cells that don’t work properly. It’s a blood-related condition, not a brain condition, and it’s about oxygen transport rather than cognitive function. The other options describe brain-related problems from alcohol use, such as cognitive impairment or memory disorders, which do not involve the red blood cell count or their oxygen-carrying capacity.
