Question

30. Calculate the IV flow rate for 500 mL DS NS How rate: hours. The IV is to be manually regulated. The drop factor is 15 gtt/min. Soome 05 - 4 = 125ml NS coo+125=625+4=39,060 Determine the BSA for each of the following children using the BSA computation formulis given in the textbook. Include two decimal places with your answers 40. Allison, who measures 56 inches tall and weighs 68 lb. BSA= 56768 = 3808 3131 1.216 1122)

Answer 1

No 1.

Total Volume is 500ml.

The infusion time is 4 hours(240 minutes).

The drop factor is 15gtt/min.

The formula for calculation of flow rate in drops is (Total volume in ml/Times in a minute)drop factor in gtt/min.

$\large (500ml\div 240min)\times 15= 31.25gtt/min$

The flow rate will be 31.25 gtt/min.

So, the required flow rate of 31 to 32 drops per minute to infuse 500ml D5NS in 4 hours.

BSA(Body Surface Area) of Allison.

The weight of Allision is 68Ib, which means 30.84killo grams.

The height of Allision is 56 inches, which means 162.56 centimeters.

The formula to calculate BSA is $\large \sqrt{\left \{\right Height(cm)\times Weight(kg)}\left\right \}/3600$

$\large \sqrt{(162.56\times 30.84)\div 3600}$

$\large \sqrt{5013.35\div 3600}$

$\large \sqrt{1.39}$

$\large = 1.17$

So, BSA = 1.17 $\large m^{2}$
