Answer to Question 1
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.
Answer to Question 2
ANS: A
The patient is experiencing respiratory acidosis (pH and PaCO2) which may be manifested by disorientation, tremors, possible seizures, and decreased level of consciousness. Tachycardia and decreased blood pressure are not characteristic of a problem of respiratory acidosis. Increased anxiety and hyperventilation will cause respiratory alkalosis, which is manifested by an increase in pH and a decrease in PaCO2.
