Question

2. You went to a grocery store and bought a lot of groceries. 25% of the total money you spent was on produce, which comprised $14.79. What was the total bill?

3. A tube feeding formula is 9% protein by volume. The patient needs 80 grams of protein per day.

How much formula should this patient get per day?

4. A patient is getting an IV infusion with 0.45% NaCl.

If a patient receives needs 5 grams of NaCl, how much total solution should be infused?

5. A parenteral nutrition formula contains 20% glucose.

If the patient needs 270 grams of glucose, how much of this formula should be infused?

Answer 1

2) You went to a grocery store and bought a lot of groceries. 25% of the total money you spent was on produce, which comprised $14.79. What was the total bill?

25% of the total money = $14.79

Therefore,

Total bill( 25% 4 = 100%) = $ 14.79 4 = $59.16

3) A tube feeding formula is 9% protein by volume. The patient needs 80 grams of protein per day.

How much formula should this patient get per day?

Given protein = 9%

The standard volume is 1000ml

Converting percentage into grams

9% per 1000ml

9 100 1000 = 90g protein

The formula to calculate the protein is

( Number of grams of protein in 1000ml) ( total litres of feeding provided) = protein in feeding

90g per 1000ml ( total litres of feeding provided) = 80g

total litres of feeding provided = 80 1000 90

= 888.8ml

888.8ml or 889ml will be administered in a day.

4) A patient is getting an IV infusion with 0.45% NaCl. If a patient receives needs 5 grams of NaCl, how much total solution should be infused?

0.45% normal saline contains 4.5g of NaCl / Liter

1Liter = 4.5 gram

1000ml = 4.5g

1ml = 4.5 1000

= 0.0045gram

100ml = 0.45gram

1000ml = 4.5gram

1100ml = 5gram of NaCl.

Total solution infused is 1100ml.

5) A parenteral nutrition formula contains 20% glucose. If the patient needs 270 grams of glucose, how much of this formula should be infused?

Given glucose = 20%

The standard volume is 1000ml

Converting percentage into grams

20% per 1000ml

20 100 1000 = 200g glucose

The formula to calculate the glucose is

( Number of grams of glucose in 1000ml) ( total litres of parenteral nutrition provided provided) = glucose in formula

200g per 1000ml ( total litres of parenteral nutrition provided) = 270g

total litres of parenteral nutrition provided = 200 1000 270

= 740ml

740ml will be given in a day.
