A nurse is preparing to administer lidocaine 2.5 mg/min to a client by continuous IV infusion. Available is lidocaine 1 g in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["38"]
To solve this problem, the nurse needs to find the concentration of lidocaine in the solution, which is 1 g / 250 mL = 0.004 g/mL.
Then, the nurse needs to convert the dosage of lidocaine from mg/min to g/hr, which is 2.5 mg/min x 60 min/hr x 0.001 g/mg = 0.15 g/hr. Finally, the nurse needs to divide the dosage by the concentration to get the infusion rate, which is 0.15 g/hr / 0.004 g/mL = 37.5 mL/hr.
Rounding to the nearest whole number, the nurse should set the IV pump to deliver 38 mL/hr.

Correct Answer is ["1"]
Explanation
To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (50 mcg / 0.05 mg) x 1 mL = 1 mL. Round to the nearest whole number: 1 mL.
Correct Answer is C
Explanation
Choice A rationale: Phenytoin is an anticonvulsant medication that is used to treat seizures. It can be given orally or intravenously, but the IV route requires careful preparation and monitoring. According to the medication label, the phenytoin is in form of an oral suspension hence it should be administered orally.
Choice B rationale: the total amount available per container is usually 5 mL not 4 mL. Choice C rationale: Phenytoin suspension should not be shaken, as it may cause the drug to precipitate. Shaking it could lead to inaccurate dosing.
Choice D rationale: The medication should also be stored at room temperature and protected from light.
