###### Answers and Rationales

**Answer: B.**(1~~mg~~/~~kg~~) x (0.3 mL/30~~mg~~) x 200~~lb~~s x (1~~kg~~/2.2~~lbs~~)=**0.9 mL****Answer: D.**180~~mg~~x (5 mL/125~~mg~~)=**7.2 mL****Answer: A.**(1,000~~units~~/ 1 hour) x (500 mL/ 50,000~~units~~)=**10 mL/hour****Answer: C.**90~~mg~~x (1 tablet/60~~mg)~~=**1.5 tablets****Answer: C.**0.6~~mg~~x (1 mL/0.4~~mg)~~=**1.5 mL****Answer: B.**2~~mg~~x (1~~gr~~/60~~mg~~) x [1 mL/(1/6~~gr~~)]=**0.2 mL****Answer: B.***Because the safe dose of codeine is variable and is determined by patient response, you only need to figure safe dose for the Tylenol for this problem. (325~~mg~~/~~tablet~~) x (2~~tablets~~/~~dose~~) x (6~~doses~~/day) x (1 gram/1,000~~mg~~)=**3.9 grams per day. Safe!***3.9 grams per day is less than the maximum safe dose of 4 grams, so it is safe.**Answer: C. 2 tablets. The patient is receiving 1.7 mcg/kg. Not safe!**- 150
~~mcg~~x (1~~mg~~/1,000~~mcg~~) x (1 tablet/0.075~~mg~~) = 2 tablets - (150 mcg/ 196
~~lbs~~) x (2.2~~lbs~~/1 kg ) = the patient is receiving 1.7 mcg/kg - *Not safe, the dose of 1.7 mg/kg is greater than 1.5 mg/kg, so the dose is too high

- 150
**Answer: A.**(250~~mL~~/ 4~~hrs~~) x (1~~hr~~/60 mins) x (10 gtts/~~mL~~)=**10 gtts/min****Answer: D.**(100 mL/ 20~~mins~~) x (1 hr/ 60~~mins~~)=**300 mL/hour**
