A physician ordered Regian (metoclopramide) 10 mg to be mixed with 50 mL of normal saline and infused over 15 minutes. A nurse must set the IV pump to deliver the medication per mL/hr as ordered.
At what rate should the solution be administered?
100 mL/hr
200 mL/hr
50 mL/hr
300 mL/hr
The Correct Answer is B
To find the rate in mL/hr, you need to use the formula for infusion rate:
Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h
Since the total volume is 50 mL, the flow factor is 1 gt/mL, and the time is 15 minutes, plug in these values into the formula:
Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 200 mL/h
Therefore, the nurse should set the IV pump to deliver **200 mL/h** to infuse Regian 10 mg over 15 minutes.

Correct Answer is D
Explanation
A lozenge is a type of medication that is designed to dissolve slowly in the mouth, usually to treat sore throat, cough, or oral infections. It should not be divided or crushed for administration because it may alter its effectiveness, taste, or absorption. It should also not be swallowed whole because it may cause choking or irritation.
A capsule is a type of medication that consists of a gelatin shell enclosing a powder or liquid. It can be opened and sprinkled on soft food or mixed with water for administration unless it is an extended-release or enteric-coated capsule.
A scored tablet is a type of medication that has a groove or indentation on its surface to facilitate breaking into equal halves or quarters. It can be divided along the score line for administration unless it is an extended-release or enteric-coated tablet.
An unscored tablet is a type of medication that does not have a groove or indentation on its surface. It can be crushed or cut into smaller pieces for administration unless it is an extended-release or enteric-coated tablet.
