SOLUTIONS TO EXERCISES, LESSON 6
1. a (para 6-23a)
2. b (figure 6-3; leg = 18 percent, abdomen = 9 percent (half of posterior trunk); 18+9=27)
3. 20 (twenty); second, third. (para 6-10)
4. d (paras 6-10b(1) through b(5); figures 6-5, 6-6)
175 lbs / 2.2 lb per kg = 80 kg (rounded)
80 x 36 = 2880
2880 x 4 = 11,520 ml (volume for first 24-hour period)
11,520 ml / 2 =5760 ml (volume for first 8-hour period)
5760 ml / 8 hr= 720 ml/hr (volume per hour for first 8-hour period)
5. 120. (paras 6-10b(6), b(7); figure. 6-6)
720 ml per hour / 60 minutes per hour = 12 ml per minute
12 ml/min x 10 drops/ml = 120 drops per minute
