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

Answer and Explanation

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.

A. Gram-positive cocci B. Gram-negative cocci C. Gram-positive bacilli D. Gram-negative bacilli

Correct Answer is A

Explanation

Choice A reason:

Gram-positive cocci are bacteria that have a spherical shape and stain purple with Gram stain due to their thick peptidoglycan cell wall. Streptococcus pyogenes is an example of gram-positive cocci that can cause infections such as pharyngitis, impetigo, cellulitis, necrotizing fasciitis, or rheumatic fever.

Choice B reason:

Gram-negative cocci are bacteria that have a spherical shape and stain pink with Gram stain due to their thin peptidoglycan cell wall and outer membrane. Neisseria gonorrhoeae and Neisseria meningitidis are examples of gram-negative cocci that can cause infections such as gonorrhea, meningitis, or septicemia.

Choice C reason:

Gram-positive bacilli are bacteria that have a rod-shaped shape and stain purple with Gram stain due to their thick peptidoglycan cell wall. Bacillus anthracis and Clostridium botulinum are examples of gram-positive bacilli that can cause infections such as anthrax, botulism, or tetanus.

Choice D reason:

Gram-negative bacilli are bacteria that have a rod-shaped shape and stain pink with Gram stain due to their thin peptidoglycan cell wall and outer membrane. Escherichia coli and Pseudomonas aeruginosa are examples of gram-negative bacilli that can cause infections such as urinary tract infection, wound infection, or sepsis.
