A patient/client was instructed to drink 25 oz of water within 2 hours but was only able to drink 15 oz. What portion of the water remained? a. 2/5 b. 3/5 c. 2/25 d. 25/25 ANS: A Feedback: Subtract the quantity of water the client drank (15 oz) from the total available quantity (2 5 oz): 10 oz remain. To determine the portion of the water that remains, create a fraction by dividing 1 0 oz (remaining portion) by 25 oz (total portion). Th erefore, 10 divided by 25 = 10/25. To reduce fractions, find the largest number that can be divi ded evenly into the numerator and the denominator (5). Ten divided by 5 (10/5) = 2; 25/5 = 5. The fra ction 10/25 can be reduced to its lowest terms of 2 /5.

A patient/client was prescribed 240 mL of Ensur e by mouth as a supplement but consumed only 100 mL. What portion of the Ensure remained? a. 5/12 b. 7/12 c. 100/240 d. 240/240 ANS: B Feedback: Subtract the quantity of Ensure the clien t consumed (100 mL) from the total available quantity (240 mL): 140 mL remain. To determine the portion of the Ensure that remains, create a fraction by dividing 140 mL (remaining portion) by 240 mL (total portion). Therefore, 140 divided by 240 = 7/12. To reduce fractions, find the largest n umber that can be divided evenly into the numerator and the denominator (20); 140 divided by 20 (140/20 ) = 7; 240/20 = 12. The fraction 140/240 can be reduced to its lowest terms of 7/12.

1 | P a g e WWW.TBSM.WS 3. A patient/client consumed oz. of coffee, 2/3 oz. of ice cream, and oz. of beef broth. What is the total number of ounces consumed that should be documented for the patient/client? a. 3 3/4 b. 4 5/12 c. 4 2/3 d. 4 4/9 ANS: B Feedback: Add the amount of ounces consumed. First, change any mixed number to a fraction by multiplying the whole number by the denominator and then adding that total to the numerator. For the coffee, 4  2 = 8 + 1 = 9/4; for the beef broth, 2  1 = 2 + 1 = 3/2. Then add: 9/4 + 2/3 (ice cream) + 3/ 2. When fractions have different denominators, find the least common denominator (LCD). For 2, 3, and 4 , the LCD = 12. Rewrite each fraction using the LCD; divide the LCD by the denominator of each fraction and then multiply that result by the numerator of the fracti on. The new fractions to be added are 27/12 (coffee ), 8/12 (ice cream), and 18/12 (beef broth). After con version of the fractions, the numerators are added together and the fraction is reduced to the lowest terms.

A coffee cup holds 180 mL. The patient/client d rank 2? cups of coffee. How many milliliters would the nurse document as consumed? a. 360 b. 420 c. 510 d. 600 ANS: B Feedback: The coffee cup holds 180 mL. The client d rank 2? cups. To estimate the total number of milliliters consumed, multiply 180  7/3 ( ). When a mixed number is present, change it to an improper fraction by multiplying the whole number b y the denominator and then adding that total to the numerator: 2  3 = 6 + 1 = 7/3. Therefore, 180 mL × 7/3 = 420 mL (180 ÷ 3 = 60 × 7 = 420).

2 | P a g e WWW.TBSM.WSc. 1.88 d. 1.98 ANS: C Feedback: To estimate the amount of kilograms gaine d, subtract weight on admission (48.52) from current weight (50.4 kg) = 1.88 kg (weight gained). To subtract decimals, decimals are stacked lined up. Starting at the far right of the stack, the num bers are subtracted. In the answer, make sure the decimal point lines up exactly with the points abov e it.

A patient/client's sodium intake for one meal w as 0.004 g and 0.152 g. How many grams, to the nearest hundredths, of sodium were consumed? a. 0.15 b. 0.156 c. 0.16 d. 0.166 ANS: C Feedback: To add decimals, stack vertically, making sure that all of the decimal points exactly line u p. Starting at the far right of the stack, add each ve rtical column of numbers. In the answer, make sure the decimal point lines up exactly with the points abov e it. To round off a decimal, the final number is dropped. Add 0.004 g + 0.152 g = 0.156 g (thousandt hs place) to determine the total number of grams the client consumed. When the final number (6) is 5 or greater, drop that number and increase the adjacent number (5) by 1. When you want a number ro unded off to the nearest hundredth, look at the number in the thousandth place and follow the round ing off rule. Therefore, 0.156 = 0.16 g.

3 | P a g e WWW.TBSM.WSFeedback: Percent means "parts per hundred." Percen t is a fraction, containing a variable numerator and a denominator that always equals 100. Therefore , 30% = 30/100 (fraction), 30:100 (ratio), and 0.3 (decimal). To determine the percent of the orange j uice the client drank, multiply 30%  16 oz. Using the decimal format (0.3  16), line up the numbers on the right. Do not alig n the decimal points. Starting at the right, multiply each digit in the t op number by each digit in the bottom number, just as is done with whole numbers. Add the products. Place the decimal point in the answer by starting at the right and moving the point the same number of place s that you totaled earlier. When blank spaces are present, fill each one with a zero.

A patient/client is on a 1500 mL fluid restric tion for 24 hours. At 3 PM, the client consumed 2/3 of the fluid allowance for 24 hours. What are the maximum milliliters of fluid remaining that the patient/client can consume during the evening shift ? a. 400 b. 450 c. 500 d. 550 ANS: C Feedback: To estimate 2/3 of 1500 mL, multiply 2/3 × 1500. Set up the fraction: 2/3 1500/1 = 3000/3 = 1000 mL (amount of fluid consumed in milli liters). Multiply the fraction by multiplying the numerators across and then multiplying denominators across. Reduce the answer to its lowest terms. To determine the amount of fluid left to be consume d, subtract 1000 (amount of fluid consumed) from 1500 mL (total amount of fluid for 24 hours), which equals 500 mL (maximum fluid to be administered during evening shift).

To estimate the amount consumed, as a fraction of the whole, set up the pr oblem as division: 0.375/0.750. Clear the decimal points in both the numerator and the denominator by moving each decimal point three places to the right. Therefore, 375/750 = 0.5 (or 1/2).

Identify the smallest amount. a. 0.2 b. 1.46 c. 0.09 d. 0.75 ANS: C Feedback: The correct order from smallest to larges t is 0.09, 0.2, 0.75, and 1.46. Size is determined by the number of places that come after the decimal po int. One place is “tenths,” two places is “hundredths,” and three places is “thousandths.” Th erefore, 0.09, read as nine hundredths, is smaller than two tenths, seventy-five hundredths, and one a nd forty-six hundredths.
