●Stool: Name two types
●Sputum:Name three types
●Throat: Name two type
●Wound: Name one type
 These are examples of what kind of laboratory tests?
A

Diagnostic

7
Q

●Purpose: To evaluate conditions which affect RBCs, WBCs, & platelets
●Indicates anemia, blood loss, inflammation, infection, response to chemo, drug SE
●Normals based on normal plasma fluid volume

What laboratory test is this?

A

CBC

8
Q

This is done to:
Assess extent of blood loss
This value must always be interpreted in relation to patient’s hydration status and the time the sample was drawn.
What laboratory test is this?

A

Hematocrit

If done immediately after hemorrhage does not show true extent of RBC loss because plasma and red blood cells are lost in equal proportions.

9
Q

RBCs and H&H are?

A

Interrelated

10

male or female? 4.2-5.4 million

What type of CBC sub-diagnostic test is this?
O2 & CO2 carrying component of RBCs
measurement of ____________ of Hgb in RBC

male or female? 13 - 18 g/dL
male or female? 12 - 16 g/dL (12-18)

What type of CBC sub-diagnostic test is this?
Percentage of ________ in total plasma volume

male or female? 45-52%
male or female? 37-48% (37-52%)

___________- decreased hematocrit, especially in the last trimester as plasma volume increases

A

12
Q

Some patients have a normal RBC count but a low hemoglobin level. This situation occurs in which red blood cells have less hemoglobin than normal. What is this disorder called?

A

Iron Deficiency Anemia

13

17
Q

__________ value must always be interpreted in relation to patient’s hydration status and the time the sample was drawn.

A

Hematocrit

18
Q

This lab test is done to:
Assess extent of blood loss
If done immediately after hemorrhage does not show true extent of RBC loss because plasma and red blood cells are lost in equal proportions.

A

Hematocrit

19
Q

RBCs normally increased at high altitudes or with strenuous physical training Why? No answer on PPT

_________ makes RBC and Hct values appear higher due to higher concentration, WNL with fluid balance

A

Dehydration

20
