 Options:  <0> To the potential of the equivalence point. <1> To the value of E0. <2> In the interval E0  0.059 / n. <3> In the interval E0 (ox) - E0 (network) if it is evaluated with a reducer. <4> At the potential of 0.059 / n.
answer:
chemistry


question:
Question: Patient of 74 years of age, asymptomatic, who in a routine analysis presents platelets 40,000 platelets / μL, the remainder being the normal blood cell count and the complete normal biochemistry. Point out the correct answer: 
 Options:  <0> The most likely diagnosis is an Idiopathic Thrombocytopenic Purpura and steroid treatment should be started as soon as possible. <1> It is a serious thrombocytopenia with a high risk of spontaneous bleeding. <2> A peripheral blood smear should be performed to rule out pseudotrombocytopenia or spurious thrombocytopenia before further measurements are made. <3> The most probable diagnosis is that of a myelodysplastic syndrome, so the initial test to be performed would be a bone marrow study. <4> An initial study should be performed with viral serologies, autoimmunity study and abdominal ultrasound. If all these tests were normal, the study should be completed with a peripheral blood smear.
