Question

A) 250 milliosmoles per kilogram

B) 285 milliosmoles per kilogram

C) 290 milliosmoles per kilogram

D) 305 milliosmoles per kilogram

E) 325 milliosmoles per kilogram

The bacterium Borrelia burgdorferi causes Lymes Disease. The disease can affect the nervous system, and often causes too great a concentration of the hormone that signals the body to reabsorb water to be present. Given the normal normal osmolarity of the cytosol in human cells is around 290 milliosmoles per kilogram, which of the following blood serum osmolarities would be indicative of a patient infected with Borrelia burgdorferi?

Explanation / Answer

A) 250 milliosmoles per kilogram.

Lymes disease is able to cause Hyponatremia , which is an electrolyte problem , which can be defined as a decrease of serum sodium concentration. The normal blood sodium level is 135 to 145 mEq/L. Hyponatremia causes the blood sodium level to be in the range of 115 to 135 mEq/L .This can cause low levels of serum osmolality , in the range of 250mOsm/kg.
