life threatening
blood pools in spleen (rupture)
s: anemia, hypovolemia, shock, palpable spleen
tm: spleen usually removed, scar, non functioning, fibrosis

Answer 19

decreased production and increased destruction of rbc, triggered by viral infection or depletion of follic acid
s: anemia, pallor

Question 20

sickle cell complications - acute chest syndrome

Answer 20

pna like
VOC or infection causes sickling in lungs, chest
s: chest, pain, fever, cough, tachypnea, wheeze, hypoxia
repeated episodes can lead to pulmonary htn
tm: manage pain, abx, ventillation, transfusion

Question 21

sickle cell tm

Answer 21

palliative: erythropoietin or hydroxyuria to increase hbgF, penicillin prophylaxis daily, doppler transcranial annually, spleen out, manage crisis (hydrate), hyper transfusion (excess Fe), bone marrow transfusion

Question 22

sickle cell crisis management

Answer 22

hydration - will decrease pain
