Answer to Question 1
ANS: D
BAL examination is performed on patients with severe lung dysfunction. They may contain airborne organisms because they are taken from the interior of the lung; they often contain bacteria and/or yeast when cytocentrifuge slides are examined. Aerosol production is a real risk; thus it is critical to wear a mask when working with these specimens.
Answer to Question 2
ANS: B
A CSF fluid is always stat, and evaluation is critical for good patient care. The cells will rapidly disintegrate, just as for all body fluid specimens, and so they must be examined within 30 minutes of draw. Diagnostic information obtained from examination of CSF fluid can be extremely important for timely and appropriate patient care; therefore in this scenario the CSF must be examined first and immediately. The clinical relevance of information obtained from hematologic examination of BAL fluid is minimal, and some hematology laboratories no longer perform counts and/or cytocentrifuge preparations on these specimens because the biohazard risk outweighs the clinical usefulness.
