A nurse is calculating the fluid intake for an infant at the end of an 8-hr shift. For oral intake, the infant had 10 mL of medication, 3 oz of formula, and 2 oz of juice. In addition, the infant had IV fluid infusing at 20 mL/hr via an IV pump. The nurse should record how many mL of intake on the clients record? (Round the answer to the nearest whole number.)
310 mL
390 mL
320 mL
180 mL
The Correct Answer is C
To calculate:
1. Convert units:
1 oz = 30 mL
3 oz formula = 3 oz x 30 mL/oz = 90 mL
2 oz juice = 2 oz x 30 mL/oz = 60 mL
2. Calculate total oral intake:
Total oral intake = 10 mL (medication) + 90 mL (formula) + 60 mL (juice) = 160 mL
3. Calculate IV fluid intake:
IV fluid intake = 20 mL/hr x 8 hr = 160 mL
4. Calculate total fluid intake:
Total fluid intake = 160 mL (oral) + 160 mL (IV) = 320 mL
Answer: 320 mL

Correct Answer is D
Explanation
Given:
Total Heparin in solution: 25,000 units
Volume of solution: 250 mL
Infusion rate: 11 mL/hr
Step 1: Calculate the concentration of Heparin in the solution:
Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL)
Concentration (units/mL) = 25,000 units / 250 mL
Concentration (units/mL) = 100 units/mL
Step 2: Calculate the infusion rate in units/hr:
Infusion rate (units/hr) = Infusion rate (mL/hr) x Concentration (units/mL)
Infusion rate (units/hr) = 11 mL/hr x 100 units/mL
Infusion rate (units/hr) = 1100 units/hr
Correct Answer is B
Explanation
A) 600 g
This is incorrect because it represents the quantity 600 grams, which is a significantly larger amount than "six hundredth." The phrase "six hundredth" refers to six out of 100, or 0.06 in decimal form. In the metric system, 600 grams would indicate a much higher quantity, far from what is requested. Therefore, this option does not fit the definition of "six hundredth."
B) 0.06 g
The term "six hundredth" refers to six parts out of one hundred, which is mathematically expressed as 0.06. In the metric system, it is common to represent small quantities of mass, such as grams, in decimal form. The number 0.06 is precisely six hundredths, and the proper representation for this in terms of grams is 0.06 g. This is the correct scientific notation for the given quantity, as it accurately reflects six hundredths of a gram.
C) 0.006 g
This is incorrect because 0.006 grams represents six thousandths, not six hundredths. In decimal notation, six thousandths would be represented as 0.006, which is one order of magnitude smaller than six hundredths. The difference between 0.006 and 0.06 is significant. While both numbers are small, 0.006 would refer to an even smaller quantity than 0.06, which is not in line with the intended meaning of "six hundredth."
D) 0.6 g
While 0.6 grams may appear similar at first glance, it represents six-tenths (6/10), not six hundredths (6/100). The number 0.6 is much larger than 0.06, and it would be used to indicate a weight that is 60% of a gram, not a small fraction like six hundredths.
