A patient has a hematocrit of 32%. What problem do they have?

• The patient is anemic, and may need a red blood cell transfusion.

• The patient has a bacterial infection, and needs antibiotics.

• The patient has a platelet deficiency, and needs a platelet transfusion.

A patient has an elevated white blood cell count. When a sample of their blood is examined under a microscope, the following is seen: 80% neutrophils, 15% lymphocytes, 3% monocytes, 2% eosinophils. What is the most likely cause of the elevated white blood cell count, based on the blood slide information?

• Penny has a viral infection.

• Penny has a parasitic infection.

• Penny has a bacterial infection.

• Penny has leukemia.

The pulmonary veins and pulmonary arteries are different from other veins and arteries in that

• pulmonary arteries carry high-oxygen blood, while all other arteries carry low-oxygen blood

• both a and b are correct statements

• pulmonary arteries carry low-oxygen blood, while all other arteries carry high-oxygen blood

• pulmonary veins carry high-oxygen blood, while all other veins carry low-oxygen blood

• pulmonary veins carry low-oxygen blood, while all other veins carry high-oxygen blood

A medical report shows the following: hematocrit 27% (normal 42-47%) WBC count 124,000/ml (normal 10,000). What conclusions may be made according to the blood slide results?

• The hematocrit is much lower than normal.

• The white blood cell count (WBC) is very high.

• The bone marrow is producing abnormal red blood cells.

• All are conclusions that can be made from the results.
