Answer to Question 1

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: Aggressive management of brain dead patients to optimize lung procurement typically includes monitoring central venous pressure, diuresis, corticosteroids, and judicious use of fluids to maintain adequate arterial pressure, with vasopressor use as needed. An intravenous bolus of Solu-Medrol (15 ml/kg) once a patient has been declared brain dead has demonstrated to improve oxygenation and lung procurement, mainly likely by mediating the pro-inflammatory response that follows brain death

Answer to Question 2

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Standard criteria for lung donation are:
  Pao2/Fio2 greater than 300 while breathing and Fio2 of 1.0
  5 cm H2O PEEP
  Clear chest radiograph
  Age less than 55 years
  No chest trauma
  Absent aspiration, sepsis, or purulent secretions
  Smoking history less than 20 pack-years
  Absent history of malignancy
C. Incorrect response: See explanation B.
D. Incorrect response: See explanation B.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
