hi
i came across these stuff in rapid review pathology and i couldn't find the answer anywhere !!!!

1. why is there an increased RBC count in thalassemia ? (page 202)
2.(page 222) why is there an increase in neutrophiles ( absolute neutrophilic leukocytosis ) in volume depletion ????? or blood loss ? and what's a tilt test ?

i'd appreciate any input ! those little things kill me !
thanks

1) abridged version: thalassemia is when the body makes crappy hemoglobin, so your functional hemoglobin drops and in order to try to combat this your body is stimulated to undergo more erythropoesis and thus a higher RBC count.

A tilt test is used to find out if a paitent has cardiac-origin pathology ( for example arrythmias) when showing the symtoms like lightheadedness, syncope. It a non-invasive test where the patient lies flat on a table and then the table is positioned upright and then tilted. Any postural hypotension or dsyrythmia on the ECG monitor suggest some pathology. A crash cart should be ready all the time since any cardiac event could occur. In fact, one of my classmates went into cardiac arrest during the test😱, but she got resuscitated. Weird huh??

Okay, I read through this once and my first thought was that you were saying that one of your classmates coded during step 1.

Hahah😀 No, of course not. It was during the tilt test.
