Answer to Question 1

ANS: A
A. Correct response: The combination of a substantial mean airway pressure to maintain recruitment and the limited tidal pressure swings should lead to reductions in both overstretch and repetitive opening-closing stresses in the lungs. In other words, HFV support is applied between the overdistention and the derecruitment points of the injured lung's pressure-volume relationship, the presumed ideal mechanical range for positive-pressure ventilatory support.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.

Answer to Question 2

ANS: A

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.

Fatal fungal infections may be able to resist newer antifungal drugs. Globally, fungal infections are often fatal due to the lack of access to multiple antifungals, which may be required to be utilized in combination. Single antifungals may not be enough to stop a fungal infection from causing the death of a patient.
