Answer to Question 1

ANS: B
The upper inflection point may indicate lung overdistention.

Answer to Question 2

ANS: C
The recruitment maneuver is stopped if there is a decrease in SpO2 to less than 88, a significant change in heart rate (>140 beats/min or <60 beats>20 mm Hg from baseline) or the development of cardi-ac arrhythmia.

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
