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.

Differential White

A blood test that measures the percentage of each type of white blood cell present in the blood and can reveal conditions such as infections, inflammation, and leukemias.

Eosinophil Count

A measure of the number of eosinophils, a type of white blood cell, in the blood, often used to diagnose allergic responses or certain infections.
