#1
Which of the following is a common symptom of anemia?
Fatigue
ExplanationFatigue is a common symptom of anemia due to decreased oxygen delivery to tissues.
#2
What is the primary function of red blood cells in the body?
Transport oxygen
ExplanationRed blood cells primarily transport oxygen to tissues throughout the body.
#3
Which of the following organs is primarily responsible for the production of red blood cells?
Bone marrow
ExplanationBone marrow is the primary site of red blood cell production, along with other blood cells.
#4
What is the main function of hemoglobin in the body?
To transport oxygen
ExplanationThe main function of hemoglobin is to bind and transport oxygen from the lungs to tissues throughout the body.
#5
What is the name of the protein responsible for transporting oxygen in red blood cells?
Hemoglobin
ExplanationHemoglobin is the protein molecule in red blood cells that binds and transports oxygen.
#6
What is the normal range for hemoglobin levels in adults?
12-18 g/dL
ExplanationNormal hemoglobin levels in adults typically range from 12 to 18 grams per deciliter (g/dL).
#7
Which nutrient is essential for the production of hemoglobin?
Iron
ExplanationIron is essential for the production of hemoglobin, the oxygen-carrying protein in red blood cells.
#8
Which type of anemia results from a deficiency in vitamin B12?
Pernicious anemia
ExplanationPernicious anemia is caused by a deficiency in vitamin B12, which is necessary for red blood cell production.
#9
What is the medical term for a low red blood cell count?
Erythropenia
ExplanationErythropenia refers to a low red blood cell count in the blood.
#10
Which of the following is a risk factor for developing iron-deficiency anemia?
Vegetarian diet without iron supplementation
ExplanationA vegetarian diet without iron supplementation can be a risk factor for developing iron-deficiency anemia due to lower intake of heme iron.
#11
What is the name of the condition characterized by a decrease in the number of white blood cells in the blood?
Leukopenia
ExplanationLeukopenia is the medical term for a decrease in the number of white blood cells in the bloodstream.
#12
Which type of anemia results from the destruction of red blood cells at an accelerated rate?
Hemolytic anemia
ExplanationHemolytic anemia is caused by the accelerated destruction of red blood cells, leading to a deficiency in circulating red blood cells.
#13
What is the name of the blood test used to measure the size and shape of red blood cells?
Mean corpuscular volume (MCV)
ExplanationMean corpuscular volume (MCV) is a blood test that measures the average size and volume of red blood cells.
#14
What does the term 'microcytic' refer to in relation to red blood cells?
Abnormally small cells
ExplanationMicrocytic refers to red blood cells that are abnormally small in size.
#15
Which of the following conditions is characterized by an abnormal increase in red blood cell production?
Polycythemia
ExplanationPolycythemia is characterized by an abnormal increase in red blood cell production, leading to thicker blood.
#16
What is the name of the inherited blood disorder characterized by abnormal hemoglobin that distorts red blood cells into a crescent shape?
Sickle cell disease
ExplanationSickle cell disease is an inherited blood disorder characterized by abnormal hemoglobin, causing red blood cells to assume a crescent shape.
#17
Which of the following is a symptom of sickle cell anemia during a crisis?
Painful episodes
ExplanationDuring a sickle cell crisis, individuals may experience painful episodes due to the blockage of blood flow by sickled red blood cells.
