Document Summary

You correctly answered: of 40 means that 40% of the volume of blood consists of rbcs. You correctly answered: is all of the above. You correctly answered: a signi cant increase in rbcs. Predict question: predict how the hematocrits of the patients living in denver, colorado (approximately one mile above sea level), will compare with the hematocrit levels of the patients living in boston, massachusetts (at sea level). https://media. pearsoncmg. com/bc/bc_0media_ap/physioex/10/ex11/act1/ i. Your answer: the hematocrits of the denver residents will be higher than those of the boston residents. You correctly answered: because hemoglobin resides in rbcs, you would anticipate a low hematocrit level to coincide with a low hemoglobin level. You scored 100% by answering 4 out of 4 questions correctly. To complete the blood test to measure hematocrit, you must seal the blood-containing capillary tubes on one end with a clay material so that.

A 23- year old male has been admitted for vomiting over the last2 days, with minimal fluid intake. He went to the emergency room ofa nearby hospital and the following data was obtained uponexamination and testing. Hematology: Hematocrit: 60% plasma pH:7.49 (normal is 7.35 to 7.45) pCO2: 47 mmHg (normal is 35 to 45mmHg) HCO3-: 31 (normal is 22 to 26 mEq/L) Urinalysis Appearance:dark yellow to brown Specific gravity: 1.025 (normal is 1.015 to1.030) Blood: negative Protein: mild pH 8.5

Questions: 1. Define acidosis and alkalosis. In general termshow can a patient develop an acidosis, an alkalosis?

2. What is the acid-base disorder this individual is sufferingfrom; explain your answer using the hematological data?

3. Has compensation occurred? If so, is it partial or complete,explain your answer?

4. Why does the patients have an alkaline urine?

A 30-year-old white man saw his family physician because of increasing fatigue over the previous few months. Physical examination revealed a pale but otherwise normal-appearing adult, although the liver and spleen to be very slightly enlarged. The patient reported that his first urine of the morning was occasionally dark brown. His physician ordered as CBC, urinalysis, and liver and spleen scan:

Parameter	Result	Reference Range
Hemoglobin	8.5 g/dL	14-18 g/dL
Hematocrit	25%	42-52%
RBC	2.6 x 10¹²/L	4.5-5.5 x 10¹²/L
WBC	4.4 x 10⁹/L	4.5-11.0 x 10⁹/L

The differential count revealed an increase in lymphocytes (60%), but the percentages of other leukocytes were within the normal range. The urine demonstrated the presence of hemosiderin. Serum iron level and reticulocyte counts were additionally requested. The total serum iron was decreased, and the reticulocyte count was increased to 13%

Questions

Based on the patient history and the laboratory results provided, what is the most likely cause for anemia in this patient?

What kind of erythrocyte morphology would you expect to observe in the peripheral blood of this patient?

What laboratory tests should be performed to confirm the diagnosis? How are they performed and what are the expected results?

What is the appropriate treatment for this disorder?

A 44-year-old white man consulted his primary provider because of pain in his shoulder and fingers. The physical examination revealed no major abnormalities but his liver was slightly enlarged and tender. A CBC and blood studies were ordered, with the following results:

Parameter	Result	Reference Range
Hemoglobin	14 g/dL	14-18 g/dL
Hematocrit	42%	42-52%
Serum iron	37 Âµg/dL	50-160 Âµg/dL
Serum ferritin	2,430 ng/mL	15-400 ng/mL
% Saturation	95%	20-55%

A liver biopsy was performed. Tissue sections revealed fatty metamorphosis and an increase in fibrous tissue in portal areas consistent with early cirrhosis. Large amounts of parenchymal iron were noted with Prussian blue staining.

Does this man have anemia? Why or why not? Based on the laboratory results and the patient history, what is the most likely diagnosis? What morphology would you expect to see in the peripheral blood? What is the most common cause of this disorder?
