Etiologic classification of anemia is based on:
-
Size
-
Color
-
Shape
-
Decreased or defective erythrocytes
Correct Answer
A. Decreased or defective erythrocytesExplanation
The etiologic classification of anemia is based on the presence of decreased or defective erythrocytes. This means that anemia can be classified based on whether there is a decrease in the number of red blood cells or if there are abnormalities or defects in the red blood cells themselves. The size, color, and shape of the erythrocytes may also be considered in the classification, but the primary factor is the presence of decreased or defective red blood cells.Rate this question:

Tissue hypoxia casues:
-
Arterioles, capillaries, and venules to consrtict
-
The heart to contract less forcefully
-
The rate of depth of breathing to increase
-
Increased afterload
Correct Answer
A. The rate of depth of breathing to increaseExplanation
Tissue hypoxia refers to a condition where there is a decreased supply of oxygen to the body's tissues. In response to this, the body tries to compensate by increasing the rate and depth of breathing. This helps to bring in more oxygen and remove carbon dioxide, improving oxygenation in the tissues. Therefore, the correct answer is that tissue hypoxia causes the rate and depth of breathing to increase.Rate this question:

Which of the following symptoms are consistent with aplastic anemia but not with pernicious anemia?
-
Petechiae and purpura
-
Pallor
-
Fatigue
-
Hypoxia
-
Neuropathy
Correct Answer
A. Petechiae and purpuraExplanation
Petechiae and purpura are both symptoms that are consistent with aplastic anemia but not with pernicious anemia. Aplastic anemia is a condition where the bone marrow does not produce enough new blood cells, leading to a decrease in the number of platelets. Petechiae are small red or purple spots on the skin caused by bleeding under the skin, while purpura refers to larger areas of similar bleeding. These symptoms occur due to the low platelet count in aplastic anemia. In contrast, pernicious anemia is caused by a deficiency in vitamin B12, leading to the production of abnormally large red blood cells, but it does not typically result in low platelet count or bleeding under the skin.Rate this question:

If a reticulocyte count were done on an individual with iron deficiency anemia because of chronic bleeding, it would be:
-
High
-
Low
-
Normal
-
Meaningless
Correct Answer
A. HighExplanation
If a reticulocyte count were done on an individual with iron deficiency anemia because of chronic bleeding, it would be high. Reticulocytes are immature red blood cells that are released into the bloodstream when the body needs to produce more red blood cells. In iron deficiency anemia, the body tries to compensate for the low levels of red blood cells by increasing the production of reticulocytes. Therefore, a high reticulocyte count indicates an active response by the body to replenish the red blood cell supply.Rate this question:

A 40 year old white, pregnant woman with four children experienced weakness, loss of appetite, and pallor. Her CBC revealed the following. A: Macrocytic RBCs 2.5 x 10 (6)/ mm (3) B: HCT level 32% C: HGB level of *.7 g/dl She mostly likely has:
-
Sickle cell anemia
-
Folic acid anemia
-
Iron deficiency anemia
-
Pernicious anemia
Correct Answer
A. Folic acid anemiaExplanation
The patient is a 40-year-old pregnant woman with weakness, loss of appetite, and pallor. The CBC results show macrocytic RBCs, low HCT level, and low HGB level. These findings are consistent with folic acid deficiency anemia. Folic acid is essential for red blood cell production, and a deficiency can lead to macrocytic anemia. This condition is common in pregnant women due to increased folic acid requirements for fetal development. Sickle cell anemia, iron deficiency anemia, and pernicious anemia would present with different laboratory findings and clinical features.Rate this question:

A cause of macrocytic- normochromic anemia is:
-
Iron deficiency
-
Deficiency of vit B12 and folic acid
-
An enzyme deficiency
-
Inheritance of abnormal hgb structure
Correct Answer
A. Deficiency of vit B12 and folic acidExplanation
A cause of macrocytic-normochromic anemia is a deficiency of vitamin B12 and folic acid. This type of anemia is characterized by larger than normal red blood cells (macrocytic) that have a normal color (normochromic). Vitamin B12 and folic acid are essential for the production of healthy red blood cells. Deficiencies in these vitamins can lead to impaired DNA synthesis and maturation of red blood cells, resulting in the characteristic enlarged size.Rate this question:

Hemolytic anemia may result in:
-
Jaundice
-
Loss of vibratory sense
-
Acidosis
-
Petechia
Correct Answer
A. JaundiceExplanation
Hemolytic anemia is a condition characterized by the destruction of red blood cells, leading to a decrease in their number. Jaundice is a common symptom of hemolytic anemia because the breakdown of red blood cells releases a pigment called bilirubin, which accumulates in the body and causes yellowing of the skin and eyes. This occurs because the liver is unable to process the excess bilirubin effectively. Therefore, jaundice is a likely consequence of hemolytic anemia.Rate this question:

The end result of anemia is:
-
Anoxia
-
Hypoxia
-
Infection
-
Bleeding
-
Hypoxemia
Correct Answer
A. HypoxiaExplanation
Anemia is a condition characterized by a decrease in the number of red blood cells or a decrease in the amount of hemoglobin in the blood. Both of these factors lead to a reduced ability of the blood to carry oxygen to the body's tissues. Hypoxia refers to a condition where there is a deficiency of oxygen reaching the body's tissues. Since anemia reduces the oxygen-carrying capacity of the blood, it can ultimately result in hypoxia.Rate this question:

An individual who has chronic gastritis and tingling in his or her fingers requires which of the following for treatment
-
Oral vitamin B 12
-
Vitamin B 12 by IM
-
Ferrous fumarate by IM injection
-
Oral folate
-
Transfusions
Correct Answer
A. Vitamin B 12 by IMExplanation
An individual with chronic gastritis may have difficulty absorbing vitamin B12 from food. This can lead to a deficiency of vitamin B12, which can cause symptoms such as tingling in the fingers. Oral vitamin B12 may not be effective in this case because it may not be absorbed properly in the digestive system. Therefore, the individual would require vitamin B12 by IM (intramuscular) injection, which bypasses the digestive system and ensures direct absorption into the bloodstream.Rate this question:

Individuals at risk for iron deficiency anemia include:
-
Who have undergone a gastrectomy
-
Who are Italian
-
With neoplastic disease
-
With warm antibodies
-
With minor, chronic blood loss
Correct Answer
A. With minor, chronic blood lossExplanation
Individuals at risk for iron deficiency anemia include those with minor, chronic blood loss. This is because chronic blood loss can lead to a gradual depletion of iron stores in the body, which can eventually result in anemia. Iron is an essential component of hemoglobin, the protein in red blood cells that carries oxygen to tissues. When there is a continuous loss of blood, such as in cases of gastrointestinal bleeding or heavy menstrual bleeding, the body may not be able to replace the lost iron fast enough, leading to iron deficiency anemia.Rate this question:

The symptoms of sideroblastic anemia may include:
-
Glossitis
-
Hepatomegaly and splenomegaly
-
Bleeding and recurrent infections
-
Neuropathy
-
Jaundice
Correct Answer
A. Hepatomegaly and splenomegalyExplanation
Sideroblastic anemia is a condition characterized by a defect in the production of red blood cells, leading to the accumulation of iron in the mitochondria of immature red blood cells. This can result in various symptoms, including hepatomegaly (enlarged liver) and splenomegaly (enlarged spleen). These symptoms occur because the liver and spleen are responsible for filtering and processing blood, and when there is an excess of immature red blood cells, these organs can become enlarged. Therefore, hepatomegaly and splenomegaly are common symptoms seen in individuals with sideroblastic anemia.Rate this question:

-
Chronic obstructive pulmonary disease in an individaul
Correct Answer
A. An increase in circulating RBC's, WBCs, and plateletsExplanation
Primary (absolute) polycythemia is a condition characterized by an increase in the number of circulating red blood cells (RBCs), white blood cells (WBCs), and platelets. This condition is not associated with a decrease in circulating plasma or a physiologic response to hypoxia. It is often seen in individuals with chronic obstructive pulmonary disease (COPD).Rate this question:

Secondary (absolute) polycythemia may be caused by;
-
Dehydration
-
COPD
-
Excessive use of diuretics
-
An abnormality of bone marrow stem cells
-
Diarrhea
Correct Answer
A. COPDExplanation
COPD, or Chronic Obstructive Pulmonary Disease, can cause secondary polycythemia. This is because COPD leads to low oxygen levels in the blood, which triggers the body to produce more red blood cells in order to compensate for the lack of oxygen. This excessive production of red blood cells results in polycythemia.Rate this question:

The pathophysiology of polycythemia ver is essentially caused by:
-
Fewer erythrocytes than normal
-
Decreased blood volume
-
An acquired mutation in Janus Kinase 2
-
Increased rate of blood flow
Correct Answer
A. An acquired mutation in Janus Kinase 2Explanation
Polycythemia vera is a condition characterized by an abnormal increase in the production of red blood cells in the bone marrow. This excessive production is caused by a specific acquired mutation in the Janus Kinase 2 (JAK2) gene. This mutation leads to the activation of JAK2, which in turn stimulates the production of red blood cells. As a result, individuals with polycythemia vera have an increased number of erythrocytes (red blood cells) in their bloodstream, leading to symptoms such as increased blood viscosity, clotting, and an increased risk of thrombosis.Rate this question:

-
Normocytic normochromic
Correct Answer
A. Macrocytic normochromicExplanation
Macrocytic normochromic anemia is a type of anemia characterized by larger than normal red blood cells (macrocytosis) with normal levels of hemoglobin (normochromic). This condition is often caused by a deficiency in vitamin B12 or folate. Vitamin B12 is necessary for the production of healthy red blood cells, and its deficiency can lead to the production of larger, immature red blood cells. This type of anemia can also be associated with other conditions such as alcoholism, liver disease, and certain medications.Rate this question:

-
Normocytic normochromic
Correct Answer
A. Microcytic hypochromicExplanation
Microcytic hypochromic is the correct answer because it refers to a type of anemia characterized by small red blood cells (microcytic) and pale red blood cells (hypochromic). Iron deficiency is a common cause of microcytic hypochromic anemia, as iron is necessary for the production of hemoglobin, the protein that carries oxygen in red blood cells. In iron deficiency, the red blood cells are smaller and paler than normal due to the lack of iron available for hemoglobin synthesis.Rate this question:

Matching: Bone Marrow depression
-
Macrocytic normochromic
-
Microcytic hypochromic
-
Normocytic normochromic
Correct Answer
A. Normocytic normochromicExplanation
Normocytic normochromic is a term used to describe the appearance of red blood cells under a microscope. It means that the cells are of normal size (neither too large nor too small) and have a normal amount of hemoglobin (the pigment that gives blood its red color). This can be seen in conditions such as anemia of chronic disease, early iron deficiency anemia, or in certain types of bone marrow disorders where the production of red blood cells is not significantly affected. Bone marrow depression, on the other hand, refers to a decrease in the production of all blood cells (including red blood cells) due to various causes, such as chemotherapy, radiation therapy, or certain medications.Rate this question:
