NURS 232 EXAM 3 (Cancer, hematology and GI disorders) Questions with Correct Answers|
Latest Update Guaranteed Success
organ responsible for filtration of the blood, breaks down hemoglobin, removes old WBCs and
stores RBCs and platelets Spleen
organ that is the primary site for production of clotting factors. It uses vitamin K to produce
prothrombin and some factors Liver
leukocytes white blood cells
eosinophils Type of WBC
Become active in certain allergic diseases/reactions, parasitic infections & medical conditions
like asthma & collagen vascular disease
monocytes Type of WBC:
Turn into macrophages & immune helper cells
Migrate into tissues for phagocytosis
basophils Type of WBC
-Appear in specific inflammatory reactions
-Contain heparin & histamine, which promotes blood flow
-Play role in parasitic infections, allergies & mediating immune system (such as B lymphocytes)
Neutrophils Most abundant WBC
-Immature neutrophil called band
-Front line defense against pathogens, especially bacterial infections; recruited within minutes
of acute inflammation from position along margin of blood vessels
-Phagocytosis action against pathogens
,-Release cytokines to stimulate inflammatory response
Lymphocytes WBCs
Three types: Natural Killer (NK) cells, T cells & B cells
-Major component of adaptive immune response
--T cells associated with cell mediated immunity
--B cells associated with humoral mediated immunity
-Recognize antigens & generate specific responses; contain toxic granules of enzymes that
digest pathogens (viral & bacterial)
-Stimulate production of antibodies from memory cells
Anemias -The most common hematologic disorder of childhood
-Decrease in number of RBCs and/or hemoglobin concentration below normal
-Increased destruction or decreased production of the RBCs
-Decreased oxygen-carrying capacity of blood
Effects of Anemia -Hemodilution
-Decreased peripheral resistance
-Increased cardiac circulation and turbulence
--May have murmur
--May lead to cardiac failure
-Cyanosis
-Growth retardation
Iron Deficiency Anemia -caused by inadequate iron intake or excessive loss of iron
-generally preventable
--iron-fortified cereals for infants
, --special needs of premature infants
S&S: pale skin, fatigue, pica, HA, dizziness, irritability, slowed thought processes, dec attention
span, apathy, and depression.
who is at highest risk for iron deficiency anemia toddlers and adolescents
(6 mo - 2 years? dairy milk)
what foods are high in iron Meats, seafood, eggs, legumes, whole grains, green leafy
vegetables, and dried fruits
Sickle Cell Anemia is what type of genetic disease? autosomal recessive
Sickle Cell Pain pain is most common problem;
crisis is result of tissue injury caused by poor oxygenation from obstructed blood flow;
what does a shortened life span of sickle cell RBC leads to -low hemoglobin with associated
symptoms of anemia
-high reticulocyte count
-elevated bilirubin and jaundice related to breakdown of large number of RBCs
What are the Triggers for sickle cell crisis Infection
Illness
Acidosis
Stress
Dehydration
