#1
What is the main characteristic of thalassemia minor?
Mild anemia
ExplanationThalassemia minor is characterized by mild anemia, often with no significant symptoms.
#2
Which of the following is a common symptom of sickle cell disease during a crisis?
Painful episodes
ExplanationPainful episodes are a common symptom of sickle cell disease during a crisis, known as vaso-occlusive episodes.
#3
What is the condition where there are fewer red blood cells than normal?
Anemia
ExplanationAnemia is a condition characterized by a lower-than-normal number of red blood cells, leading to reduced oxygen-carrying capacity.
#4
What is the term for the premature destruction of red blood cells?
Hemolysis
ExplanationHemolysis is the term for the premature destruction of red blood cells, leading to a release of hemoglobin into the bloodstream.
#5
Which of the following is NOT a symptom of sickle cell disease?
Aplastic anemia
ExplanationAplastic anemia is not a symptom of sickle cell disease; common symptoms include painful episodes and anemia.
#6
Which type of thalassemia results from mutations in both beta-globin genes?
Beta-thalassemia major
ExplanationBeta-thalassemia major results from mutations in both beta-globin genes, leading to severe anemia.
#7
Which of the following is NOT a symptom of thalassemia?
High blood pressure
ExplanationHigh blood pressure is not a symptom of thalassemia; symptoms typically involve anemia-related issues.
#8
What is the treatment for severe thalassemia major?
Blood transfusions and chelation therapy
ExplanationSevere thalassemia major is treated with regular blood transfusions and chelation therapy to manage iron overload.
#9
Which type of hemoglobin is primarily affected in sickle cell disease?
Hemoglobin S
ExplanationSickle cell disease primarily affects hemoglobin S, leading to the characteristic sickle-shaped red blood cells.
#10
What is the cause of sickle cell disease?
Mutation in the HBB gene
ExplanationSickle cell disease is caused by a mutation in the HBB gene, resulting in the production of abnormal hemoglobin.
#11
What is the term for the process of removing excess iron from the body in individuals with iron overload disorders?
Chelation therapy
ExplanationChelation therapy is the process of removing excess iron from the body, commonly used in iron overload disorders.
#12
Which of the following is a possible complication of untreated thalassemia?
Osteoporosis
ExplanationUntreated thalassemia can lead to complications such as osteoporosis due to abnormal bone formation.
#13
Which of the following is NOT a characteristic feature of hereditary spherocytosis?
Iron deficiency anemia
ExplanationIron deficiency anemia is not a characteristic feature of hereditary spherocytosis, which involves spherical-shaped red blood cells.
#14
Which of the following is NOT a characteristic of hemolytic anemia?
Decreased bilirubin levels
ExplanationDecreased bilirubin levels are not characteristic of hemolytic anemia, which involves the premature destruction of red blood cells.
#15
Which of the following is NOT a symptom of hereditary spherocytosis?
Hypoglycemia
ExplanationHypoglycemia is not a symptom of hereditary spherocytosis; symptoms are related to the destruction of red blood cells.
#16
What is the term for the genetic condition in which red blood cells are more prone to rupture?
Erythroblastosis fetalis
ExplanationErythroblastosis fetalis is a genetic condition where red blood cells are more prone to rupture, particularly in newborns.
