Question

d. Fill in the blank: Glucose provi solution provides kcal/ml. the blank: Glucose provides energy at a rate of 4 kcal Ut a rate of 4 kcal/gram. Therefore a 5% glucose 2. Sometimes medications are prescribed on the m'). If a doctor prescribes a medication of soon is 40 inches tall, medical staff can determine the total de formula first to calculate the approximate body surface prescribed on the basis of the patient's body surface area (BSA in edication of 500mg/m2 to 3 Vear old boy who weighs 35 lbs and ne the total dosage for the boy by using the Mosteller te body surface area (BSA) of the boy: approximate body surface area of the average person having The Mosteller formula provides the approximate a specified height and weight: BSA = inches x lbs 3131 a. Find the BSA of the 3-year old boy. Round your answer y. Round your answer to the nearest hundredth.

Answer 1

1. Energy rate produced by glucose=4 K cal/gm

Therefore,energy by 5% glucose =5 /100 *4 K cal/gm

=0.2 K cal /ml (as 1 gm =1 millilitre)

So,0.2 K cal/ ml energy is provided by 5% glucose.

2. a. Body Surface Area =$\dpi{100} \fn_cm \small \sqrt{inches* lbs\div 3131}$

= $\dpi{100} \fn_cm \small \sqrt40*35 }\div 3131$

=0.07069 m ²

=70.69 m ²(rounded to nearest hundredth).

So,the body surface area of the 3 year old boy is 70.69 m ².

2. b. Total dosage in milligrams = 500 mg *0.07069 m ²

=35.345 mg

=35345 mg (rounded to the nearest whole number)

So,the total dosage in milligrams is 35345 mg.

2. c. In order to calculate the dose (in grams),we need to know the Body surface area. 5' 8" is equal to 68 inches.

So, Body Surface Area =$\dpi{100} \fn_cm \small \sqrt{inches* lbs\div 3131}$

=$\dpi{100} \fn_cm \small \sqrt{68*190 \div 3131}$

=0.5004 m ²

Dosage needed = 750 mg * 0.5004 m ²

= 375.3 mg /m ²

= 0.3753 grams

= 3753 grams(rounded to the nearest whole number).

So.the dose of medication needed in grams is 3753 grams.
