Question

Questions for Hematology class:

1. Hypoplasia is usually assocaited with bone marrow C:F ratio

		<1
		>1
		=1
		< or > than 1
		none of the above

2. Which one of the following anti-coagulants has the anti-thrombin activity?

		EDTA
		Heparin
		sodium citrate
		ammonium Oxalate
		None of the above

3. Use internet or other sources to look up SLE (Lupus) and answer the following question.

Characteristics associated with SLE are (choose all that apply)

		Production of anti-RBC antibodies
		Prodcution of anti-DNA
		Autoimmune disease
		induced by bacteria infection
		Presence of LE cells. Look up what is LE cells.

4. Anisocytosis

		Measure the total percent of both microcytes and macrocytes in the blood
		Measure the total percent of just microcytes in the blood
		Measure the total percent of just macrocytes in the blood
		Measure the total percent of normocytes in the blood

5. Poikilocytosis

Measure the total percent of abnormal shapes of RBC in the blood

Abnormal high number of keratocytes will end up with high percent of poikiolcytosis

abnormality usually associated with high poikiolcytosis

high poikilocytosis always indicate high anisocytosis

6. Hypochromic

		More than 1/3 pallor in RBC
		old RBC are always hypochromic
		total hemoglobin contents in the RBC will be lower than the normochromic RBC
		oxygen carrying capacity is usually lower than that of normocytes

Answer 1

1. Hypoplasia is the term used to describe about decreased number of cells.

In hypoplasia is usually associated with bone marrow C:F ratio <1.

2.

Heparin.

Heparin is the natural anticoagulant, which also acts against the thrombin.

3.SLE (systemic Lupus erythematosus ) is the autoimmune disorder in which autoimmune antibodies are produced which destructs the tissues and organs of body.

Antinuclear antibodies are produced.

SLE is characterized by

Autoimmune disease

Induced by bacterial infection

4.

Anisocytosis is the medical term means that patient's red blood cells are in unequal size.

Anisocytosis is measurement of total percentage of macrocytes and microcytes in the blood.

5.poikilocytosis is the measurement of total percentage of abnormal shapes of RBC.

6.Hypochromic means total hemoglobin content in the RBC will be lower than normochromic RBC
