Question

2) JF is a 73-year-old male patient who is 6 feet 1 inch tall and weighs 220 lb. He is ambulatory and has a severe infection.

Calculate his TDE. Answer with three decimal places.

4) If a 50% dextrose injection provides 170 kcal in each 100 mL, how many milliliters of a 25% dextrose injection would provide the same caloric value?

6) If a person consumes 2500 calories per day, calculate the intake of fat, in grams, based on dietary fat being 30% of caloric intake. Round to two decimal places.

23) A fluconazole injection contains 400 mg of fluconazole in 250 mL of normal saline injection for infusion. Calculate the concentration of fluconazole in mg/mL.

Answer 1

2. TDEE = BMR x activity level

(for light exercise or sedentary lifestyle activity level is 1.2)

BMR =  (height in centimeters x 6.25) + (weight in kilograms x 9.99) – (age x 4.92) + 5

TDEE= 1976

4. 1gm dextrose contain 3.4kcal/g

Total calorie = (25g/100ml) x amount of solution in ml x 3.4kcal/g

170 = 0.25 x amount of solution in ml x 3.4

170 = 0.85 x amount of solution

Amount of solution = 170/ 0.85 = 200 ml

6. 2500calories per day x 0.30 = 750calories from fat per day.

there are 9 calories in each gram of fat

750calories from fat per day divided by 9 = 83.33 fat grams per day

23. Concentration of drug = 400mg / 250ml = 1.6 mg/ml
