I am beyond overwhelmed at the moment with this class and lif in general. I have a lecture exam and lab quiz today and have been battling a kidney stone (will probably be going in for surgery on Thursday to have it removed) and completely overlooked the fact that this lab is due today as well. I don't have time to run all of the labs at this moment. Any help would be greatly appreciated!

Hematocrit Determination
1.) Hematocrit value for healthy male living at sea level in Boston =
Hematocrit value for healthy female living at sea leve in Boston =
2.) Were the values listed in question 1 within normal range?
3.) Describe the difference between the male and female hematocrit for an individual living in Boston?
4.) Hematocrit value for healthy male living in Denver =
Hematocrit value for healthy female living in Denver =
5.) How did these values differ fromthe vaules of Boston?
6.) Describe the effect of living at high elevations on a persons hematocrit? ( I am assuming they will be higher??)
7.) Describe how he kidney's respond to a decreasein oxygen and what effect this has on hematocrit.
8.) Hematocrit value for male with aplastic anemia =
% WBC for male with aplastic anemia=
9.) Were the values listed in question 8 witin the normal range? Why or why not?
10.) Hematocrit for female with iron-deficiency anemia=
11.) Was the value in question 10 normal or not? Explain.

Erythrocyte Sedimentation Rate
12.) Describe the effec that sickle cell anemia has on the sedimentation rate.
13.) Why d you think that it has this effect?
14.) Record the sedimentation rate for a menstruating female.
15.) How did this value compare to the healthy individual? Why?
16.) What was the sedimentation ratefor he iron-deficient individual?
17.) What effect does iron deficiency have on ESR?
18.) ESR for person suffering from a myocardial infarction=
ESR for person suffering from angina pectoris=
19.) Compare the values in question 18 and explain how they might be used to monitor heart conditions.
20.) Listsome other conditions tha ES is used to monitor.

Hemoglobin
21.) Describe the ration of packed cell volume to Hb obtained for the healthy male and female subjects.
22.) Describe the ratio of packed cell volume to Hb for the female with iron-deficiency anemia.
23.) Is the female with iron-deficiency anemia deficient in hemoglobin?
24.) Is the male with polycythemia deficient in hemoglobin?
25.) Is the female Olympic athlete deficient in hemoglobin?
26.) List conditions in which Hb would decrease.
27.) List conditions in which Hb would increase.


Thanks again for any help. If I can get these filled in at least it woul be half done...

BLOOD ANALYSIS - Answers


Please note:  I do not include the charts as you still have to do the experiments and print the data and graphs.

Also remember, many of your answers are in the text preceding each activity.



Activity 1


What is the hematocrit value of a healthy male living at sea level in Boston?

   a. 48

What is the hematocrit value of a health male living at one mile elevation in Denver?

   a. 55

Is there as much oxygen in the air in Denver as there is in Boston?

   a. No - the air in Denver is thinner (lower percentage of oxygen)

How do your kidneys respond to a decrease in blood oxygen? (Review this section in your textbook if necessary.)

   a. When the blood flowing through the kidney's is hypoxic (low oxygen level), the kidneys respond by producing a hormone, erythropoietin, which stimulates the bone marrow to produce more red blood cells.

If your bone marrow is producing an elevated number of red blood cells, what happens to your hematocrit?

   a. your hematocrit is elevated

What is the hematocrit value of the male with aplastic anemia?

   a. 19

Would the red blood cell count for an individual with aplastic anemia be higher, lower, or the same as the red blood cell count of a healthy individual?

   a. lower

What is the hematocrit value of a healthy female living in Boston?

   a. 44

Explain the difference in hematocrit values obtained from a healthy female living in Boston and a female with iron-deficiency anemia.

   a. The female with iron-deficiency anemia does not have as any normal sized red blood cells as the healthy female in Boston, so her hematorcrit (packed cell volume) is lower.  She is not able to make adequate hemoglobin molecules to fill her red blood cells.



Activity 2

How many millimeters has the blood settled?

   a. 5 mm

Did the person with sickle cell anemia show an elevated ESR?

   a. no

How did the ESR for a person with iron-deficiency anemia compare to the ESR for a healthy individual?

   a. the person with iron-deficiency anemia was higher than the healthy individual

Explain the ESR for sample 2, the menstruating female.

   a. The menstruating female is suffering from iron-deficiency anemia, causing her red blood cells to settle.

Explain the ESRs for samples 5 and 6 (the patients suffering from myocardial infarction and angina pectoris, respectively.)

   a. The patient suffering from myocardial infarction (heart attack) has an elevated ESR.  But the patient with angina pectoris has a normal ESR.



Activity 3

What is the hematocrit value for the healthy male?

   a. 48

What is the hematocrit value for the healthy female?

   a. 44

What does the ratio of PCV to Hb tell you about the red blood cells of the female with iron-deficiency anemia?

   a. She may have a normal number of red blood cells, but they do not contain adequate levels of hemoglobin molecules.

Does the male with polycythemia have a normal ratio of PCV to Hb?

   a. yes - male = 20 hb/100 ml blood

Based on these results, do you think that his red blood cells contain adequate quantities of hemoglobin molecules?  Why?

   a. no - his red blood cells show an elevated count of hemoglobin molecules (24) - normal for men is 13.5 - 18

Does the female Olympic athlete have a normal ratio of PCV to Hb?

   a.  yes - 3:1

Based on these results, do you think her red blood cells contain adequate quantities of hemoglobin molecules?  Why?

   a. yes - her ratio is 3:1 which shows an adequate level of hemoglobin molecules.



Activity 4

If the anti-A antibody causes the blood to coagulate, which antigen would be present on the blood cells?

   a. A

If a person has type AB blood, which antigens are present on the red blood cells?

   a. A and B

Which antibodies are present in the plasma of a person with AB blood?

   a. neither

Does a person with type O blood have A or B antigens on the red blood cells?

   a. neither



Activity 5

What health problems might be in store for patient 2, based on these results?

   a. can be a candidate for atherosclerosis (increased risk of cardiovascular disease)

What advice about diet and exercise would you give patient 4?

   A. Lower dietary intake of cholesterol (red and organ meats, eggs, cheese) and increase aerobic exercise.

The answers I gave you are for the actual experiements, but they should help you on your answers on the review sheet.  The other answers should come from the text preceeding each of the experiements as well as the review test.  Sorry, it is 3:30 am here and I just woke and saw your plea so I thought I would give you what I could.  Hope it helps.

You're very welcome!  If you run the experiements, it will take you about 30 minutes so you can fill in the charts and you will have all the expriement done.  The answers for the review sheet are found in the experiments and the text preceeding each experiement, and you can also google.  I suggest you run the experiments as then you will get a full understanding of everything.  Good luck with the stone!
