When analyzing synovial fluid, if it has 10,000 white blood cells/mcL with 80% polymorphonuclear neutrophils (PMNs), it may be indicative of which of the following conditions? a. None, this is a normal result
b. Scleroderma
c. Rheumatoid arthritis
d. Sickle cell disease

A.

Explanation:The colorless fluid, secreted by the ependymal cells of the choroid plexus  of the brain ventricles and  distributed in the brain and spinal cord is called the CSF. These fluids are absorbed in the arachnoid.

Its function is to provide nourishment,removes wastes,and maximum protection for the brain.

Generally the  normal WBC count of the blood  is between 5,000 and 10,000.This is the amount that is also present i CSF. Since the components are similar to that of the blood.Therefore the sample of the CSF is normal.

In SS,there is apoptoisis (death) of the PMNS,therefore this can not be correct. Macrophages rate increases in R.Arthritis, but  decrease Neutrophil release.

the ecg findings of an acute anterior myocardial infarction wall include: st segment elevation in the anterior leads (v3 and v4) at the j point and sometimes in the septal or lateral leads, depending on the extent of the mi. this st segment elevation is concave downward and frequently overwhelms the t wave.
