**Answer: B.**10~~mg~~x (1 mL/5~~mg~~)=**2 mL****Answer: A.**40~~mg~~x (2 mL/20~~mg~~)=**4 mL****Answer: D.**15~~mg~~x (1~~gr~~/60~~mg~~) x [ 1ml/ (1/6~~gr~~) ]=**1.5 mL****Answer: C.**8~~mg~~x (1 mL/5~~mg~~)=**1.6 mL****Answer: B.**(20~~mL~~/1~~hr~~) x (1~~hr~~/ 60 mins) x (60 gtts/~~mL~~)=**20 gtts/min****Answer: A. patient is receiving 20 mg/hour; yes, dose is safe**- Because you have to compare a safe dose to the patient’s dose, you have to do two separate calculations:
- (0.36 mg/
~~kg~~) x (1~~kg~~/ 2.2~~lbs~~) x 130~~lbs~~= 21.3 mg/hr is safe - (20
~~mL~~/hour) x (100 mg/100~~mL~~)= patient is receiving 20 mg/hr; yes, dose is safe.
