Blood Analysis Lab Quiz

This activity contains 25 questions.

	Refer to Activity 1: Hematocrit Determination. Hematocrit refers to:   the percentage of platelets in a sample of whole blood. the percentage of red blood cells in a sample of whole blood. the percentage of white blood cells in a sample of whole blood. the volume of plasma in a given blood sample.

	Of the test subjects, who has the highest hematocrit value?   The healthy female living in Boston. The healthy female living in Denver. The healthy male living in Denver. The healthy male living in Boston.

	Of the test subjects, who has the lowest hematocrit value?   The healthy male living in Denver. The healthy male living in Boston. The healthy female living in Boston The male with aplastic anemia.

	If your bone marrow is producing an elevated number of red blood cells, what happens to your hematocrit?   The hematocrit value remains constant. The hematocrit value decreases. The hematocrit value increases. The hematocrit value will fluctuate as a function of the white blood cell count.

	What is the hematocrit value of the woman with iron deficiency anemia?   55 53 48 32

	Refer to Activity 2: Erythrocyte Sedimentation Rate. The erythrocyte sedimentation rate measures what?   The height of the white blood cells that have settled in a stationary, vertical tube after 1 hour. The height of the red blood cells that have settled in a stationary, vertical tube after 1 hour. The length of the white blood cells that have settled in a stationary, horizontal tube after 1 hour. The length of the red blood cells that have settled in a stationary, horizontal tube after 1 hour.

	Refer to Activity 2. How many millimeters has the blood settled for tube 1?   0 mm 5 mm 15 mm 30 mm

	What was the ESR for the menstruating female? Do you predict this to be higher or lower than when she is not menstruating?   0mm/hr; The rate would be higher. 5 mm/hr; The rate would be higher. 15mm/hr, The rate would be lower. 30mm/hr; The rate would be lower.

	How would the ESR for a person with iron deficiency anemia compare to the ESR for a healthy individual?   The ESR would stay the same. The ESR would be lower. The ESR would be higher.

	How does myocardial infarction affect the ESR?   It causes an increase in the ESR. It causes a decrease in the ESR. The ESR would not be different from normal.

	What is the ESR of the individual with angina pectoralis?   0mm/hr 5mm/hr 15mm/hr 30mm/hr

	Refer to Activity 3: Hemoglobin (Hb) Determination. What is the normal hemoglobin content for a male with polycythemia?   8 gm Hb/100ml blood 14 Hb/100ml blood 16 Hb/100ml blood 20 Hb/100ml blood

	What is the red blood cell ratio of PCV to Hb for the female with iron deficiency anemia?   2.72 3 3.14 5

	What is the ratio of PCV to Hb in the female Olympic athlete?   2.72 3 3.14 5

	From the results of this experiment, what can be said about the ratio between Hb content and packed cell volume?   The greater the ratio, the lower the Hb content in the blood. The greater the ratio, the greater the Hb content in the blood. The lower the ratio, the greater the Hb content in the blood. The lower the ratio, the lower the PVC content in the blood.

	Based on these results, who has the least amount of Hb content in their blood?   The healthy male The female with iron deficiency anemia The male with polycythemia The healthy female

	Refer to Activity 4: Blood Typing. If a person has type O+ (Rh positive) blood, which antigen(s) are present on the red blood cells?   Type O Rh antigens Type A Type B

	Which antibodies are present in the plasma of a person with type AB blood?   Type A antibodies Type B antibodies Rh antibodies Type O antibodies No antibodies are present.

	Which sample is from a person who has B+ (Rh positive) blood?   Sample 1 is B+. Sample 2 is B+. Sample 3 is B+. Sample 4 is B+. Sample 5 is B+. Sample 6 is B+.

	Which sample shows antigens present for all three agglutinogens?   Sample 1 Sample 2 Sample 3 Sample 4 Sample 5 Sample 6

	If a woman has O+ (Rh Positive blood), from which sample subject could she receive a transfusion?   Sample 1 Sample 2 Sample 3 Sample 4 Sample 5 Sample 6

	Refer to Activity 5: Cholesterol Determination. Cholesterol is produced   in the stomach. in the liver. in the pancreas. in the kidneys.

	Which patient is at increased risk for heart disease?   Patient 1 Patient 2 Patient 3 Patient 4

	Which patient is borderline elevated? What was the cholesterol value determined to be?   Patient 1; 200 mg/dL Patient 2; 300 mg/dL Patient 3; 150 mg/dL Patient 4; 225mg/dL

	Which patient may be at risk for hyperthyroidism?   Patient 1 Patient 2 Patient 3 Patient 4 None of the patients are at risk.
