A nurse is reviewing laboratory results for a client with microcytic and hypochromic red blood cells. Which type of anemia does this finding suggest?
Hemolytic anemia
Sickle cell anemia
Thalassemia
Pernicious anemia
The Correct Answer is C
A) This choice is incorrect because hemolytic anemia typically presents with normocytic and normochromic red blood cells, as the bone marrow compensates by releasing immature red blood cells.
B) This choice is incorrect because sickle cell anemia is characterized by the presence of sickle-shaped red blood cells and is not associated with microcytic and hypochromic cells.
C) This choice is correct. Thalassemia is a type of anemia in which the synthesis of globin chains is impaired, leading to microcytic and hypochromic red blood cells.
D) This choice is incorrect because pernicious anemia is associated with macrocytic and normochromic red blood cells due to vitamin B12 deficiency.

Correct Answer is B
Explanation
A) This choice is incorrect because petechiae, which are tiny red or purple spots on the skin, are associated with platelet disorders and not directly related to anemia.
B) This choice is correct. Pallor (pale skin) and jaundice (yellowing of the skin and mucous membranes) are related clinical manifestations of anemia. Jaundice can occur in hemolytic anemias when the breakdown of red blood cells leads to an accumulation of bilirubin.
C) This choice is incorrect because cyanosis, a bluish discoloration of the skin, is not directly related to anemia.
D) This choice is incorrect because diaphoresis, or excessive sweating, is not a typical clinical manifestation of anemia.
Correct Answer is D
Explanation
A) This choice is incorrect because folate-deficiency anemia is associated with a deficiency of folic acid, often caused by poor dietary intake or malabsorption, but not specifically linked to alcoholism.
B) This choice is incorrect because hemolytic anemia is characterized by the destruction of red blood cells and is not directly related to alcoholism.
C) This choice is incorrect because sickle cell anemia is a genetic disorder and is not caused by alcohol consumption.
D) This choice is correct. Macrocytic anemia is commonly associated with alcoholism due to the direct toxic effects of alcohol on bone marrow, resulting in the production of larger-than-normal red blood cells (macrocytes).
