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.)

Answer and Explanation

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 ["1.5"]

Explanation

To calculate the amount of phenobarbital to administer per dose after the initial dose, the nurse should use the following formula:

mL = (dose in mg) / (concentration in mg/mL)

The dose in mg is 200 mg, and the concentration in mg/mL is 130 mg/mL. Plugging these values into the formula, we get:

mL = (200 mg) / (130 mg/mL)

mL = 1.5385

Rounding to the nearest tenth, the nurse should administer 1.5 mL per dose after the initial dose.

Correct Answer is ["1"]

Explanation

To answer this question, you need to convert the dosage of fentanyl from micrograms (mcg) to milligrams (mg). One milligram is equal to 1000 micrograms, so 50 mcg is equal to 0.05 mg. Then, you need to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 0.05 mg, H is 0.05 mg/mL, and Q is the volume in milliliters. Plugging these values into the formula, you get:

0.05 mg / 0.05 mg/mL x Q

Q = 1 mL

Therefore, the nurse should administer 1 mL of fentanyl per dose.
