Question
Part 2: Your patient has lost a lot of blood. Because his blood type was unknown at first they did a ringers and then plasma replacement for volume instead of whole blood. This morning's complete blood cell count showed a hematocrit of 37% They determined that his blood type was B-. Two of his siblings showed up to donate blood.His sister is ype O- and his brother is type A D) How is this possible? Draw the genetic squares (one for ABO and one for Rh +/- to show what E) Which sibling is the better blood donor? Why? 1 point F)During traumatic shock the body undergoes a sever loss of blood volume. What would this loss genetic types the parents must be. What is the 4 possible genetic type? 2 points of blood volume do to the blood pressure? How might the body try and compensate for the loss in pressure in terms of blood vessels and cardiac effort? What will happen to the overall blood flow?2 pointsExplanation / Answer
D] The father has blood group B and mother has bllood group A
FATHER [ blood group B]
MOTHER [ blood group A] Offsprings can have blood groups A, B, AB and O
The presence or absence of Rh factor determines the -- ve and + ve blood types.
Presence of Rh factor will result in + [ for the presence of this factor] .
Absence of Rh factor will result in -- [ for the absence of this factor]
A person with --ve condition can donate blood to another person with a + ve condition [ assuming that the antigens match ] but a person with + ve condition cannot donate to -- ve condition person.
E] The sister having blood group O -- is the better blood donor. This is so because she neither has antigen A or B. Also, she is negative for Rh factor. So , she can safely donate blood to her brother who is B-- without any fear of any complications.
F] Heavy loss of blood will cause a fall in the blood pressure of the person.
The fall in blood pressure will result in increasing the heart rate and narrowing the veins to return more blood to the heart.
Vasodilation causes increase in blood flow so to compensate the fall in blood pressure the blood vessels will constrict.
The blood flow to different parts of body will be inadequate and it might prove dangerous for a person's life.
