Calculate the Clinical Pulmonary Infection Score (CPIS) for a patient with the following assess-ments: 56-year-old female, post motor vehicle accident, intubated, and mechanically ventilated for 4 days.

Static compliance is 42 cm H2O/L. Tracheobronchial suctioning reveals a moderate amount of yellow secretions; culture and sensitivity are pending. Breath sounds reveal bilateral lower lobe coarse rhonchi. Chest radiograph shows diffuse infiltrates. Partial pressure of oxygen in the ar-teries (PaO2) is 72 mm Hg on 40 supplemental oxygen. Patient has a temperature of 39.2 C, and white blood cell count (WBC) is 12,800 L.
a. CPIS = 5
b. CPIS = 6
c. CPIS = 7
d. CPIS = 8

d. Staphylococcus aureus

Answer to Question 1

ANS: C
Using the CPIS criteria found in Table 14-2, the score is calculated as follows: Temperature of 39.2 C = 2 points; white blood cell (WBC) is 12,800 L = 1 point; secretions are present and nonpurulent = 1 point; partial pressure of oxygen in the arteries/fractional inspired oxygen (PaO2/FIO2) = 72/0.4 = 180 with no acute respiratory distress syndrome (ARDS) = 2 points; chest radiograph shows diffuse infiltrates = 1 point; and compliance and saturation in the blood phase (C & S) is pending = 0 point, for a total of 7 points.

Answer to Question 2

ANS: A
The upper airways of healthy individuals typically contain nonpathogenic bacteria, such as the viridans group of streptococci, Haemophilus sp., and anaerobes.
