A. Respiratory disease that results in the blood being poorly oxygenated
B. The presence of hematomas in the skin
C. Hypertension caused by excessive use of the medication
D. Anemia
Answer: A. Anemia
Explanation: Red blood cells(RBCs) help give blood its color. Anemia is a set of signs and symptoms that appear when a person does not have enough healthy RBCs. Pallor, or paleness, is a sign/symptom of anemia because the blood vessels in the dermal layer lack normal RBCs.
