Answer to Question 1

ANS: B
First calculate ideal body weight (IBW) for a male, using the formula 106 + 6(ht  60). This pa-tient's IBW is 97 kg. Minute ventilation is about 100 mL/kg IBW, which would be 97,000 mL/min or 9.7 L/min.

Answer to Question 2

ANS: B
First calculate ideal body weight (IBW) for a female, using the formula 105 + 5(ht  60). This patient's IBW is 51 kg. Minute ventilation is about 100 mL/kg IBW, which would be 51,000 mL/min or 5.1 L/min.
