Instructions: Calculate the flow rate in units/hr (Equipment used is programmable in whole units/hr). Order: 100,000 units of Heparin in 1,000 mL to infuse at 50 mL/hr. Calculate the rate in units/hr.
5000 units/hr
500 units/hr
2000 units/hr
2500 units/hr
2500 units/hr
The Correct Answer is A
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.

Correct Answer is B
Explanation
To calculate the dosage, we need to use the formula:
Dosage (mL) = Ordered dose (mg) / Available dose (mg/mL)
Plugging in the given values, we get:
Dosage (mL) = 175 mg / 25 mg/mL
Simplifying, we get:
Dosage (mL) = 7 mL
Therefore, the dosage is 7 mL.
Correct Answer is D
Explanation
To calculate the dosage using the ratio and proportion method, we need to set up a proportion that compares the ordered dose to the available dose. In this case, we have an order of 1.0 g of Amoxil and capsules labeled 250 mg per capsule. We can use the formula:
ordered dose / available dose = x / 1 capsule
where x is the number of capsules to administer. We need to convert the units to the same ones, so we can change 1.0 g to 1,000 mg. Then we can plug in the values and solve for x:
1,000 mg / 250 mg = x / 1 capsule
Cross-multiply and simplify:
250x = 1,000
x = 1,000 / 250
x = 4
Therefore, the number of capsules to administer is 4.
