A condition in which the blood is deficient in red blood cells, in hemoglobin, or in total volume.

A condition in which the blood is deficient in red blood cells, in hemoglobin, or in total volume.

• A. Aneurysm
• B. Angina
• C. Dyspnea
• D. Anemia

Answer: (D)

This describes anemia, a condition where the blood’s oxygen-carrying capacity is reduced because there are too few red blood cells, not enough hemoglobin, or a loss of blood volume. Red blood cells and hemoglobin are essential for transporting oxygen from the lungs to tissues throughout the body. When their numbers or concentration drop, tissues receive less oxygen, leading to fatigue, weakness, pallor, and shortness of breath with activity. The other terms refer to different cardiovascular issues: an aneurysm is an abnormal bulge in a blood vessel, angina is chest pain from heart muscle ischemia, and dyspnea is a difficulty breathing symptom that can arise from many conditions but does not define a blood deficiency state.
