Calculate the flow rate in mL/hr. (The equipment used is programmable in whole mL/hr).
Order: 100 mL 0.45% NS in 45 minutes by infusion pump.
Calculate the rate in mL/hr.
145 mL/hr
133 mL/hr
125 mL/hr
135 mL/hr
The Correct Answer is B
To solve this problem, we need to use the formula:
Rate (mL/hr) = Volume (mL) / Time (hr)
Plugging in the given values, we get:
Rate (mL/hr) = 100 mL / 0.75 hr
Rate (mL/hr) = 133.33 mL/hr
However, this is not the final answer because the equipment used is programmable in whole mL/hr, which means we need to round the rate to the nearest whole number. Therefore, we need to apply the rounding rule: if the decimal part is 0.5 or more, round up; if the decimal part is less than 0.5, round down. In this case, the decimal part is 0.33, which is less than 0.5, so we round down. This gives:
Rounded rate (mL/hr) = 133 mL/hr
Therefore, the correct flow rate is 133 mL/hr.

Correct Answer is A
Explanation
To solve this problem, we need to find the concentration of heparin in the solution and then multiply it by the infusion rate. The concentration of heparin is the amount of heparin divided by the volume of the solution. In this case, the concentration is:
100,000 units / 1,000 ml = 100 units/ml
The infusion rate is given as 50 ml/hr. To find the flow rate in units/hr, we multiply the concentration by the infusion rate:
100 units/ml * 50 ml/hr = 5000 units/hr
Therefore, the flow rate in units/hr is 5000 units/hr.
