a. How many mcg/kg/min will the patient receive? (show work)

b. Is the dose within the theraputic range?

Solutions

Expert Solution

a 9.5 mcg/kg/min

first determine how many milligrams/hour is being delivered by the IV pump. The rate of the IV (cc/hr) is divided by the volume of the IV bag (mL available), then multiply this result by the total amount of medication (mg) in the IV bag.

      rate      
mL available

 x dose available

becomes

22mL/hr
500mL

 x 750mg

Next, after the milligrams/hour has been determined, use the next formula to convert from milligrams/hour to mcg/kg/min.

mg  
60min

 x 1000 / kg

Return to:which = 9.5 mcg/kg/min

b Yes, the dose is with in the range as the dosage is 0.5 to 20 mcg/kg/min
