To provide for minor adjustments, arches are sometimes designed with:

A patient with asthma is extremely short of breath and hypoxic. Related to the ventilation/perfusion ratio (V/Q), the EMT would recognize the problem lying in:

A) inadequate oxygen in the alveoli. B) decreased cardiac output to circulate oxygen. C) inadequate oxygen in the ambient air. D) decreased blood volume to carry oxygen.

A technologist is performing a body fluid analysis on a CSF specimen recently received in the laboratory. Four CSF tubes were sent to the body fluids bench. The tech notices that all four specimens seem moderately blood tinged equally

What is the most likely reason for these findings? a. This was a traumatic specimen collection. b. The patient has a CNS lymphoma. c. The patient is suffering from a subdural hemorrhage. d. The wrong patient was drawn.
