1. Convert to a fraction a. 20%b. 25%c. 80% | 1. a. 1/5 b. 1/4 c. 4/5 |
2. Convert to a percent a. 1/10b. 1/3c. 2/3d. 3/4 | 2. a. 10% b. 33% c. 66% d. 75% |
3. Supply: 240 cc can of full strength Sustacal. How much water and how much Sustacal is needed to administer a feeding of 200 cc of ¾ strength Sustacal? | a. Cc Sustacal = (200/1)(3/4)= 150 cc Sustacal b)200cc-150cc = 50cc of water |
4. What strength solution will result if 80 cc of water is added to a 240cc can of 100% Ensure? | 4. 240 cc Ensure + 80 cc water = 320 cc totalDesired strength = (240 (CV)/320(tv))= 0.75 or 3/4 strength |
5. On hand is a 180 cc can of 100% Enrich. How much water is needed to give a 180 cc feeding of ¼ strength Enrich? | 5. cc water = (180cc/1)(3/4)= 135 cc water |
6. Supply is 480 cc of full-strength Sustacal. 120 cc water is added. What is the strength of the resulting solution ? | 6. 480 cc + 120 cc = 600 cc ......... 480 cc/600 cc = 80% or 4/5 |
7. Supply is a 240 cc can of 100% Sustacal. How much water will be needed to administer a total of 240 cc of ½ strength Sustacal? | 7. (TV)(DS) = CV....... (240 cc)(1/2strength) = 120cc CV..... 240 (TV) - 120 (CV) = 120 cc water |
8. How much water is in a 225 cc feeding that is 75% strength? | 8. cc water = (225 cc (TV))(0.25 water)= 56.25 or 56.3 cc water |
9. On hand is an 8 oz. can Sustacal. How many ml water will be needed to make the Sustacal a 2/3 strength feeding? | 9. Ml Sustacal = (30 mL/1oz)(8 oz/1)= 240 mL Sustacal ...... 1 oz 1 (240 mL Sustacal)÷ (2/3) = 240 X (3/2) = (720/2) = 360 TV – 240 = 120 cc water |
10. Supply: 40 cc Osmolite. When 4 fluid ounces water is added, what is the strength of the solution? Express your answer as a fraction. | 10. cc water = 30 mL/ 1 oz X 4 oz. = 120 mL water ..... 40 cc Osmolite + 120 cc water = 160 cc TV ..... 40 cc Osmolite ÷ 160 cc TV = 1/4 strength |
11. How much water is in a 250 cc feeding that is ½ strength? | 11. cc water = 250 cc X 1/2 = 125 cc |
12. In a solution of 400 cc of ¾ strength Jevity, what is the CV? | 12. cc Jevity = 400 cc X 3/4 = 300 cc Jevity |
13. If there is 100 cc water in a 2/3 strength feeding solution, what is the TV? | 13. TV = 100 cc ÷ 1/3 = 100 cc X 3/1 = 300 cc |
14. If a client is to receive 2400 calories daily and the Ensure contains 240 calories/ 8 oz. can, how many mL Ensure will the client receive daily? | 14. mL/ day = (30 mL/1oz)(8oz/240cal)(2400 cal/1day)= 2400 mL Ensure/ day |
15. If the above feeding is to be 75% strength, how much water will be added to the feeding daily? | 15. TV = CV ÷ DS ..... cc TV = (2400 mL/(3/4)(2400 mL)(4/3)= 9600/3 = 3200 TV ......3200 TV – 2400 CV = 800 cc water |
16. A client is to receive a continuous drip feeding of Ensure. There are 240 cal/ 8oz. can of Ensure. The feeding is to provide 2000 cc/ 1500 calories. What is the strength of the feeding? Express the answer as a percentage. | 16. cc Ensure = (30 mL/1oz)(8 oz/240 cal)(1500 cal)= 1500 cc Ensure .......TV = 2000 cc .....CV ÷ TV = DS ..... (1500 cc/2000cc)= 3/4 = 75% |
