A nurse is caring for a client who has leukemia. The nurse understands that this condition is characterized by what type of neoplasia?
Benign neoplasia of blood cells
Malignant neoplasia of blood cells
Benign neoplasia of bone marrow cells
Malignant neoplasia of bone marrow cells
The Correct Answer is D
Choice D reason:
Malignant neoplasia of bone marrow cells. Leukemia is a type of cancer that originates from the abnormal and uncontrolled growth of hematopoietic stem cells or progenitor cells in the bone marrow. These cells can proliferate and differentiate into various types of blood cells, such as lymphocytes, granulocytes, monocytes, or erythrocytes. Leukemia can be classified by the type of cell involved (myeloid or lymphoid) and the rate of progression (acute or chronic).
Choice A reason:
Benign neoplasia of blood cells is not a correct term for leukemia, as leukemia is a malignant condition that can invade and destroy normal blood cells and tissues. Benign neoplasia of blood cells is a rare condition that involves the overproduction of normal blood cells, such as polycythemia vera or essential thrombocythemia.
Choice B reason:
Malignant neoplasia of blood cells is not a correct term for leukemia, as leukemia does not originate from blood cells, but from bone marrow cells. Malignant neoplasia of blood cells is a term that can be used for lymphoma, which is a type of cancer that originates from lymphocytes in the lymphatic system.
Choice C reason:
Benign neoplasia of bone marrow cells is not a correct term for leukemia, as leukemia is a malignant condition that can spread to other organs or systems. Benign neoplasia of bone marrow cells is a term that can be used for myelodysplastic syndrome, which is a condition that involves the abnormal development and maturation of bone marrow cells.

Correct Answer is D
Explanation
Choice A reason:
Atrophy is a decrease in cell size or number in response to adverse stimuli, such as disuse, ischemia, or malnutrition. It does not increase the risk of cancer, but it can impair the function of tissues and organs.
Choice B reason:
Hypertrophy is an increase in cell size in response to normal or abnormal stimuli, such as exercise, hormones, or hypertension. It does not increase the risk of cancer, but it can affect the function of tissues and organs.
Choice C reason:
Hyperplasia is an increase in cell number in response to normal or abnormal stimuli, such as hormones, inflammation, or wound healing. It does not increase the risk of cancer, but it can cause excessive growth of tissues and organs.
Choice D reason:
Dysplasia is an abnormal and potentially reversible change in cell size, shape, and organization in response to persistent stressors. It can be a precursor to cancer if it is not detected and treated early.
Correct Answer is D
Explanation
Choice A reason:
Increased hydrostatic pressure in the portal vein is one factor that causes ascites. The portal vein carries blood from the digestive organs to the liver for processing. However, when the liver is damaged by alcohol abuse, it becomes scarred and fibrotic, creating resistance to blood flow. This results in increased pressure in the portal vein and its branches, which forces fluid out of the capillaries into the abdominal cavity.
Choice B reason:
Decreased oncotic pressure in the plasma is another factor that causes ascites. Oncotic pressure is the force exerted by proteins in the plasma that attracts fluid into the capillaries from the interstitial space. However, when the liver is damaged by alcohol abuse, it cannot produce enough proteins, such as albumin and globulin, which are essential for maintaining oncotic pressure. This results in decreased oncotic pressure in the plasma and increased fluid movement into the interstitial space and the abdominal cavity.
Choice C reason:
Increased aldosterone secretion by the adrenal glands is another factor that causes ascites. Aldosterone is a hormone that regulates the balance of sodium and water in the body. It acts on the kidneys to increase the reabsorption of sodium and water from the urine into the blood. However, when the liver is damaged by alcohol abuse, it cannot metabolize aldosterone properly, leading to its accumulation in the blood. This results in increased sodium and water retention in the body and increased fluid movement into the interstitial space and the abdominal cavity.
Choice D reason:
Ascites is caused by a combination of factors that affect the fluid balance in the abdominal cavity.
