PNB 2265 PRACTICAL 1 EXAM QUIZZES
WITH RIGHT ACCURATE ANSWERS .
hemoglobin - Correct Answer -•transports blood gases
•can carry 4 O2 on heme
•uses Fe on center
•2 alpha and 2 beta chains
blood composition - Correct Answer -•plasma
-92% water
-7% proteins (albumin, globulin, clotting factors)
•buffy coat
-platelets
-leukocytes
•erythrocytes
normal blood smear - Correct Answer -
neutrophils - Correct Answer -•granulocyte
•most abundant
•pale colored granules
•multi-lobed nucleus
NEVER LET MONEYS EAT BANANAS
eosinophils - Correct Answer -•granulocyte
•reddish granules
•bi-lobed nucleus
1
,basophils - Correct Answer -•granulocyte
•least abundant
•dark blue-violet granules
lymphocytes - Correct Answer -•agranulocyte
•little cytoplasm surrounding nucleus
•round, dark nucleus
monocytes - Correct Answer -•agranulocyte
•kidney-shaped nuclei, lighter stained
•more cytoplasm surrounding nucleus
platelet - Correct Answer -
type A blood - Correct Answer -•has type A antigens on surface of RBC
•person has type B antibodies
•can receive type A, O
•donate to type A, AB
•agglutination if type B, AB
universal recipient - Correct Answer -type AB
universal donor - Correct Answer -type O
Rh factor - Correct Answer -•Rh surface antigen = surface antigen D
•if agglutination of sample --> positive!
-i.e. A+, AB+
hemolytic disease of the newborn - Correct Answer -•occurs in Rh- mothers carrying Rh+
children
2
, •mother has antibodies against Rh+ because she is Rh-
•mother given RhIg (immunoglobulin)
-prevents sensitization to D antigen
-binds with fetal RBC with Rh+ before mother can product anti-Rh response
hemagglutination - Correct Answer -•pre-formed antibodies opposite to person's blood type
bind to antigens on foreign blood and stick together
•can block blood vessels
antibodies - Correct Answer -produced by B lymphocytes in response to exposure to foreign
antigens
centrifuge loading - Correct Answer -sealing clay facing out and all balanced
hemoglobinometer - Correct Answer -•measures amount of hemoglobin in blood
•set to 540 nm
-highest point of intersection
-measuring total hemoglobin conc
•measured as grams per 100 mL
•11-16% for women
•13-18% for men
hematocrit - Correct Answer -•fraction of whole blood volume that is made up of RBC
•47 +/- 7% for men
•42 +/- 5% for women
effects on hemoglobin and hematocrit levels - Correct Answer -•dehydration
-Hb same
-hematocrit up
•polycythemia
-both up
