I need the review answers for PhysioEx 9.0 Exercise 11 Blood Analysis.
Activity 1 (Hematocrit Determination1. List the hematocrits for the healthy make (sample 1) and female (sample 2) living in Boston (at sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia.
2. Describe the difference between the hematocrits for the male and female living in Boston. Why does this difference between the sexes exist?
3. List the hematocrits for the healthy male and female living in Denver (approximately one mile above sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia.
4. How did the hematocrit levels of the Denver residents differ from those of Boston residents? Why? How well did the results compare with your prediction?
5. Describe how the kidneys respond to a chronic decrease in oxygen and what effect this has on hematocrit levels.
6. List the hematocrit for the male with aplastic (sample 5) and indicate whether it is normal or abnormal. Explain your response.
7. List the hematocrit for the female with iron-deficiency anemia (sample 6) and indicate whether it is normal or abnormal. Explain your response.
Activity 2 Erythrocyte Sedimentation Rate1. Describe the effect that sickle cell anemia has on the sedimentation rate (sample 3). Why do you think that it has this effect?
2. How did the sedimentation rate for the menstruating female (sample 2) compare with the sedimentation rate for the healthy individual (sample 1)? Why do you think this occurs?
3. How did the sedimentation rate for the individual with angina pectoris (sample 6) compare with the sedimentation rate for the healthy individual (sample 1)? Why? How well did the results compare with your prediction?
4. What effect does iron-deficiency anemia (sample 4) have on the sedimentation rate?
5. Compare the sedimentation rate for the individual suffering a myocardial infarction (sample 5) with the sedimentation rate for the individual with angina pectoris (sample 6). Explain how you might use this data to monitor heart conditions.
Activity 3 Hemoglobin Determination1. Is the male with polycythemia (sample 4) deficient in hemoglobin? Why?
2. How did the hemoglobin levels for the female Olympic athlete (sample 5) compare with the hemoglobin levels for the healthy female (sample 2)? Is either person
deficient in hemoglobin? How well did the results compare with your prediction?
3. List conditions in which hemoglobin levels would be expected to decrease. Provide reasons for the change when possible.
4. List conditions in which hemoglobin levels would be expected to increase. Provide reasons for the change when possible.
5. Describe the ration of hematocrit to hemoglobin for the healthy male (sample 1) and female (sample 2). (A normal ratio of hematocrit to grams of hemoglobin is approximately 3:1.) Discuss any differences between the two individuals.
6. Describe the ratio of hematocrit to hemoglobin for the female with iron-deficiency anemia (sample 3) and the female Olympic athlete (sample 5). (A normal ratio of hematocrit to grams of hemoglobin in approximately 3:1.) Discuss any differences between the two individuals.
Activity 4 Blood Typing1. How did the appearance of the A, B, and Rh samples for the patient with AB- blood type compare with your prediction?
2. Which blood sample contained the rarest bloody type?
3. Which blood sample contained the universal donor?
4. Which blood sample contained the universal recipient?
5. Which blood sample did not agglutinate with any of the antibodies tested? Why?
6 What antibodies would be found in the plasma of blood sample 1?
7. When transferring an individual with blood that is compatible but not the same type, it is important to separate packed cells from the plasma and administer only the packed cells. Why do you think this is done? (Hint: Think about what is
in plasma versus what is
on RBC's.)
8. List the blood samples in this activity that represent people who could donate blood to a person with type B+ blood.
Activity 5 Blood Cholesterol1. Which patient(s) had desirable cholesterol level(s)?
2. Which patient(s) had elevated cholesterol level(s)?
3. Describe the risks for the patient(s) you identified in question 2.
4. Was the cholesterol level for patient 4 low, desirable, or high? How well did the results compare with your prediction? What advice about diet and exercise would you give to this patient? Why?
5. Describe some reasons why a patient might have abnormally low blood cholesterol.
