Jim has type AB+ blood. What type(s) of blood can he receive in a transfusion? a. All of these choices are correct b. O+ or O- c. AB + or AB- d. B+ or B- e. A+ or A-
a
The least numerous leukocyte is the: a. Basophil b. Neutrophil c. Monocyte d. Lymphocyte e. Eosinophil
a
Which of the following has a diameter of 8-10 µm, a nucleus that is difficult to see, and large deep blue-purple granules? a. Basophils b. Monocytes c. Lymphocytes d. Neutrophils
a
2-4% of all WBCs are of this type. a. Basophils b. Eosinophils c. Monocytes d. Lymphocytes e. Neutrophils
b
Do the hematocrit and hemoglobin content of blood measure the same thing? a. No. The hematocrit determines the oxygen-carrying ability of the blood in mg/mL of blood and the hemoglobin measures the percent of RBCs in whole blood. b. No. The hematocrit measures the percent of RBCs in whole blood and the hemoglobin content determines the oxygen-carrying ability of the blood and is described in mg/mL of blood. c. Yes. They both measure the percent of RBCs in whole blood. d. Yes. They both determine the oxygen-carrying ability of the blood in mg/mL of blood.
b
Janey has a hematocrit of 58%. Is this within the normal range? a. Yes, the normal range for females is 50 - 60 %. b. No, the normal range for females is 38 - 46 %.
b
Large cells that develop into platelets are called: a. thrombocytes b. megakaryocytes c. eosinophils d. basophils
b
Ron has a hematocrit of 47%. Is this within the normal range? a. No, the normal range for males is 35 - 45 %. b. Yes, the normal range for males is 40 - 50 %.
b
Staci has antibody A in her blood with no Rh antibody. What blood type does she have? a. A+ b. B- c. AB- d. A- e. B+
b
The most numerous leukocyte is the: a. Lymphocyte b. Neutrophil c. Eosinophil d. Basophil e. Monocyte
b
These cells help the body fight infections and foreign substances. a. Megakaryocytes b. White blood cells c. Thrombocytes d. Red blood cells
b
What blood type is the universal recipient? a. AB- because this blood type has no antibodies to attack any other blood group b. AB+ because this blood type has no antibodies to attack any other c. blood group d. O- because it is also the universal donor e. O+ because this blood type has no antigens to attack any other blood group
b
Which of the following is the cell that carries oxygen and carbon dioxide? a. Thrombocyte b. Red blood cell c. Platelet d. White blood cell
b
0.5-1% of all WBCs are of this type. a. Monocytes b. Eosinophils c. Basophils d. Neutrophils e. Lymphocytes

c
Michael is type O-. He is donating blood today and wants to know what blood types can accept his blood. What would you tell him? a. Only the O types can accept his blood b. Only the B types can accept his blood c. All blood types can accept his blood d. Only the A types can accept his blood
c
Which of the following is 10-12 µm in diameter with a nucleus that has 2 or 3 lobes and red-orange granules? a. Neutrophils b. Basophils c. Eosinophils d. Monocytes
c
60-70% of all WBCs are of this type. a. Lymphocytes b. Monocytes c. Eosinophils d. Neutrophils e. Basophils
d
Lindsey had a differential WBC count that showed 60% neutrophils, 10% eosinophils, 1% basophils, 22% lymphocytes, and 7% monocytes. What could have caused this? 1. When eosinophils are high, an allergy may be the cause. 2. When eosinophils are high, a parasitic infection or an autoimmune disease may be the cause. 3. When neutrophils are high, a viral infection may be the cause. 4. When monocytes are high, a bacterial infection may be the cause. a. 3 only b. 1 only c. 4 only d. Both 1 and 2 are correct e. 2 only
