Question

16) At the adjusted flow rate, how much IV should be infused in 4 hours? 17) At the ordered flow rate, how long does it take to infuse 1000 ml? A doctor orders Sargramostin IV for a child with a height of 25 inches and a weight 9.0 kg. The recommended adult dosage is 250 cg/m2/day. Available solution is 500 mcg/10 ml 18) Use the west Nomogram provided to determine the child's BSA. 19) Use the Mosteller formula to find the child BSA 20) What is the recommended child dosage in meg/day? 2 points 21) How many mls should this child receive in one day? Order: Penicillin G potassium 400,000 units IV PB q.4h for a child who weighs 10 kg Supply: Penicillin G potassium reconstituted to 200,000 units/ ml. Recommended administration from package insert: Penicillin G potassium 100,000- 250,000 Unit/kg/day in divided doses q.4h 2) What is the maximum dosage in units/dose can this child receive? What the minimum dosage in units/dose can this child receive? How many units/day is ordered for this child? Is it safe? 2points

Answer 1

16, flow rates are adjusted to the desired drops per minute

Formula= Amount of fluid(mc)/Total time of infusion (min)X drop factor(gtts/ml) = IV infusion rate (gtts/min)

17, ordered flow rate gtts/min = tubing drop factor (gtt)/1ml X amount of fluid to be infused( 1000ml)/time (in hr) X 1hr/min

18, west nomogram

Height 25inches

Weight 9kg

BSA = 0.46

19, mosteller formula

BSA (m2)= ( height (cm) X weight (kg)/3600)/1/2

( 63.5X 9/3600)1/2

571.5/3600X2 = 0.3175m2

BSA = 0.3175m2
