Question

Please show how to calculate answer is below WITH A question mark next to it .

A patient in the critical care unit is on a TPN solution (25% CHO, 5%AA) @ 85cc/hour with 10% lipids QOD. The patient information includes ht: 5’10”; wt: 185lb (84 kg); age: 67; sex: Male. Calculate the glucose utilization rate for this nutrition support regimen.

1)	2.4mg/kg/min

2)	4.2 mg/kg/min ?

3)	4.5 mg/kg/min

4)

5.6kg/mg/min

An elderly female patient in long-term care is on an enteral feeding. The nursing staff reports the patient is febrile with a present temperature of 102.6^o F. How much should the R.D. adjust the kcalorie requirements?

1)

52%

2)

25%

3)

7%

4)

28%

Answer 1

1. Glucose infusion rate is a measure of how quickly the patient receives carbohydrates. Typically, this number should be less than 4 mg/kg/min in order to prevent hyperglycemia and steatosis.

Use the following equation to determine a glucose infusion rate:

GIR in mg/kg/ min = % of dextrose x (Infusion rate, mL/hr) / (Weight, kg) x 6

= 25 x 85 / 84 x 6

=4.2 mg/ kg / min

1. BMR rises 7% for each degree the body temperature rises above 98.6 F. BMR rises 13% for each degree the body temperature rises above 37 C.

In the question temperature of the patient is 102.6 °F.

So the answer is 7 x 4 =28 %
