Peds Hematologic/Immunologic Dysfunction Flashcards
skin examination for children with hematologic dysfunction
pallor, petechiae, bruising
anemia
-Decrease in number of RBCs or hemoglobin (Hgb) which decreases the oxygen-carrying capacity of blood
Anemia with reduced Hgb concentration may be caused by
a dietary depletion of iron
s/s of anemia
lack of energy, easy fatigability, and pallor
Aplastic anemia
is a condition that occurs when your body stops producing enough new blood cells.
treatment for aplastic anemia
medications, blood transfusions or a stem cell transplant, also known as a bone marrow transplant.
red cell aplasia (PRCA) or erythroblastopenia
a type of anemia affecting the precursors to red blood cells but not to white blood cells. The bone marrow CEASES to produce red blood cells.
Immune thrombocytopenic purpura (ITP)
a bleeding disorder in which the immune system destroys platelets, which are necessary for normal blood clotting. People with the disease have too few platelets in the blood.
Disseminated intravascular coagulation (DIC)
a rare, life-threatening condition. DIC causes your blood to clot excessively. As a result, blood clots may reduce blood flow and block blood from reaching bodily organs.
treatment for anemia
-Transfusion after hemorrhage if needed
-Nutritional intervention for deficiency anemias
supportive care for anemia
-Intravenous (IV) fluids to replace intravascular volume
-Oxygen therapy
-Bed rest
iron deficiency anemia more common in
toddlers between 12 to 36 months and during the growth spurt in adolescence
Abnormal Hgb levels are common in what racial or ethnic groups
Southeast Asians, Africans , and Mediterranean
Hemoccult test
a lab test for hidden blood in the stools; tests for chronic intestinal bleeding
Decrease tissue oxygen needs:
Signs of exertions
tachycardia, palpitations, tachypnea, dyspnea, shortness of breath, hyperpnea (increased depth and rate of breathing), dizziness, lightheadedness, diaphoresis, and change in skin color. The child looks fatigued
Explaining Blood Components to Children: RBCs
Carry the oxygen you breathe from your lungs to all parts of your body.
Explaining Blood Components to Children: WBCs
Help keep germs from causing infection.
Explaining Blood Components to Children: platelets
Small parts of cells that help make bleeding stop by forming a clot (or scab) over the hurt area.
Explaining Blood Components to Children: Plasma
The liquid portion of blood, which has clotting factors that help make bleeding stop.
What is iron deficiency anemia caused by?
inadequate supply of dietary iron
Milk babies
overweight infant because of excessive milk ingestion
2 reasons become anemic: milk (poor source of iron)
increased fecal loss
liquid preparation of iron may
temporarily stain teeth; brush teeth after admin to lessen staining
iron-rich foods
iron-fortified cereals
lean meat, poultry, and fish
tofu
egg yolks
beans
raisins
what helps iron to get absorbed
Serve fruits and vegetables high in vitamin C or a glass of orange juice at mealtimes
Don’t give cow’s milk to babies under
1 year old
Sickle Cell Anemia
-Partial or complete replacement of normal Hgb with abnormal HbS
-Defect is inherited
sickle cell anemia onset
Newborns with SCA are generally asymptomatic because of the protective effect from the mother, Rapidly decreases during the first year, then child manifests symptoms
In areas of world where malaria is common, individuals with sickle cell trait tend to have
survival advantage over those without trait
