Blood
match the number to create the correct sequence of steps in a hematocrit determination
1. fill a glass capillary with blood from a disinfected finger tip 2. seal off the capillary on one end with a putty 3. place you capillary into a centrifuge with the sealed end facing outwards 4. balance the centrifuge by loading it evenly 5. spin the capillaries for about 4 min 6. place the capillary over the evaluation grid
rank the steps below into the correct sequence necessary to prepare a blood smear. place the first step at the top
1. obtain a drop of blood and place it away from the center onto a slide 2. take a clean slide and slide it at a 45 degree angle across the first slide to distribute the drop of blood evenly on the first slide. let the blood dry 3. put a few drops of Wright's stain onto the slide. leave the slide to dry for about 2 minutes 4. add as much buffer as Wright stain onto the slide. let the slide stand for 2-4 minutes 5. rinse the slide with water
when donor and recipient have the exact same blood type, like B+ for example, their blood will obviously match. what if the recipient type does not match the donor type
A Rhesus positive recipient can always receive Rhesus negative blood of the same type. Recipients with type AB+ can receive any type of donor blood cells (packed cells), but not any type of plasma. Any recipient can receive type O red blood cells (packed cells) but not the type O plasma
match the blood type and antibodies that would normally be present in a person's plasma
O = anti-A and anti-B in plasma A = anti-B in plasma B = anti-A in plasma AB = no antibodies in plasma
a male athlete has a hematocrit of 55% prior to a competition. that indicates
an endurance trained male in the norm range
a woman with a hemoglobin content of 10g/100ml would be considered ___ in regards to her saturation
anemic
a person with blood type O has ___ in their blood plasma
anti-B antibodies, anti-A antibodies
with what information do you want to label your slide
blood sample number. serum type.
which blood test(s) would be used to determine if a donor's blood is compatible with the blood of a recipient
blood typing
how is the differential white blood cell count determined
by counting a set number of white blood cells and nothing the percentages of different types of cells
formed elements of blood include which of the following structures
cells, cell fragments
if someone who does not have type O blood receives a type O transfusion, they can only receive the a portion of the blood. they can receive the ___, but not the ___
cells; plasma
which blood test(s) would be used to determine the presence of a parasitic infection
differential white blood cell count
where would antibodies be found in the blood
dissolved in plasma
we need as much wright's stain as
is necessary to cover all the blood smear
what is the purpose of the hemolysis applicator
it breaks down red blood cells and releases hemoglobin to the solution
when handling someone else's blood, you should always wear ___ ___ on your hands
latex gloves
the formed elements in blood that are involved in the immune-defense of the body are called ___
leukocytes
a patient's hemoglobin content is determined to be 12g/100ml. that is
low for a man, but normal for a women
a patient's hemoglobin content is determined to be 10g/100ml. that is
low for both a woman or a man
when you move the slide in the hemoglobinometer, your goal is to ___ the two colors
match
match the white blood cell type with the correct description
neutrophil = polymorphonuclear slightly pinkish granular cytoplasm lymphocyte = large round nucleus takes most of the space in the cell; small cytoplasm ring around nucleus monocyte = large cell, twice as big as a red blood cell. nucleus is "bean" or "c" shaped eosinophil = cell full of red-pink staining granules; nucleus is bilobed basophil = cell is full dark-purple staining granules; nucleus is bilobed
a patient's hematocrit is determined to be 45% that is
normal for both a man or a woman
where are the A, B, and Rh antigens located
on erythrocyte
the full capillary tube should be sealed
on one side after we put blood in so that the blood will not be pushed out in the centrifuge
what problem is most likely the case when a person has a high count of eosinophils
parasitic infection, allergic reaction
the liquid portion of blood is called
plasma
the formed elements that allow blood to clot are called ___ ad they look like ___
platelets -- very small, roundish spots
the essential transport of oxygen in our body is conducted by ___ blood cells
red
the most abundant of the formed elements in blood are ___
red blood cells
match the blood component with its major function
red blood cells = transport of respiratory gases white blood cells = provide immune surveillance and defense platelets = enable self-sealing of wound plasma = transports nutrients, proteins, hormones and distribute body heat
with the hematocrit measurement we determine one of the important factors that determine
the oxygen transport capacity of a person's blood
with the hemoglobin measurement we determine one of the important factors that determine
the oxygen transport capacity of a person's blood
how should the capillary tubes be placed in the centrifuge?
the sealed end of the capillary should lie at the edge. capillary tubes should be placed on opposite sides of the centrifuge to balance it. the capillary tube should touch the rim of the centrifuge.
based on the results of your differential white blood cell count, which of the following statements is most likely correct
the white blood cell numbers are normal. the patient doesn't have any problems
which of the following statements best describes what you would expect to happen in a packed cell transfusion if the recipient had blood type A and the donor had blood type O
