The nurse is assessing a patient's differential white blood cell count. What implications would this test have on evaluating the adequacy of a patient's gas exchange?
a. An elevation of the total white cell count indicates generalized inflammation.
b. Eosinophil count will assist to identify the presence of a respiratory infection.
c. White cell count will differentiate types of respiratory bacteria.
d. Level of neutrophils provides guidelines to monitor a chronic infection.
ANS: A
Elevation of total white cell count is indicative of inflammation that is often due to an infection. Upper respiratory infections are common problems in altering a patient's gas exchange. Eosinophil cells are increased in an allergic response. Neutrophils are more indicative of an acute inflammatory response. White cells do not assist to differentiate types of respiratory bacteria. Monocytes are an indicator of progress of a chronic infection.
