Q

Complete the formula:

V02 = ____ x _____ x ____ x (_____ - _____)

A

The attached formula is for oxygen delivery

V02 = 1.39 x Q x Hb x (SaO2 - SvO2)

where Q = blood flow (ml/min)
Hb = hemoglobin (gm/dl)
SaO2 = % saturation of arterial blood (100 mmHg)
SvO2 = % saturation of venous blood (40 mmHg)

Q

YES OR NO - the ff. steps of hemostasis is arranged in the proper order

Coagulation phase - activation of clotting system and clot formation
Platelet phase - platelet aggregation and adhesion
Vascular phase
Clot destruction - ezymatic destruction of clot
Clot retraction - contraction of blood clot

A

NO - the steps are not in order

Vascular phase
Platelet phase - platelet aggregation and adhesion
Coagulation phase - activation of clotting system and clot formation
Clot retraction - contraction of blood clot
Clot destruction - ezymatic destruction of clot

Q

It is the process of RBC production.

A

Erythropoeisis

17
Q

The hormone ____________ is produced in the _________ which stimulates the bone marrow to produce more RBCs.

A

Erythropoietin; kidneys

18
Q

It is a type of anemia caused by an increase in the RBCs rate of destruction.

A

Hemolytic anemia

19
Q

This anemia is may be caused by defective heme synthesis and symptoms include pallor along with glossitis and cheilitis.

A

Iron-deficiency anemia

20
Q

This causes megaloblastic anemia because the GI tract is not producing enough intrinsic factor - a necessary substance in the absorption of this mineral. This condition is coupled with altered thought processes like confusion and dementia.

A

Cobalamin (Vitamin B12 Deficiency)

21
Q

This is the main cause of _________ anemia in which RBCs are large and few. The main difference of this from the previous type of anemia is that there is an absence of neurologic conditions.

A

Folic Acid Deficiency; magablastic anemia

22
Q

This is an autosomal recessive condition in which there is an irregularity in the production of either the alpha or beta globin chains - leading to a decrease in hemoglobin production.

23
Q

_____________ is a type of anemia caused by bone marrow failure. It’s called ______________ if it’s inherited.

A

Aplastic anemia; fanconia anemia

24
Q

Pancytopenia is when there is a decrease in _________________.

A

All blood cell types

25
This condition is autosomal recessive in which the hemoglobin component of an erythrocyte is malformed - leading to difficulty in transportation. This may also lead to a painful vasooclusive condition.
Sickle Cell Disease
26
It is caused by lesions and wounds where one is losing blood faster than they're producing it.
Blood loss
27
This condition is characterized by having a decrease in platelets causing problems in the clotting cascade. It may be autoimmune.
Thrombocytopenia
28
This is a condition characterized by an overload of iron in the blood. Furthermore, it may cause liver, heart, and pancreas failure.
Hemochromatosis
29
Hyperviscosity is when ______________
There is an excess of red blood cell mass.
