A nurse is preparing to administer metronidazole 500 mg by intermittent bolus over 60 min. Available is metronidazole 500 mg in 100 ml 0.9% sodium chloride. 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 ["100"]

To calculate the IV pump rate in mL/hr, you need to divide the volume of the solution in mL by the infusion time in hr. In this case, the formula is 100 mL / 1 hr = 100 mL/hr.

Therefore, the nurse should set the IV pump to deliver 100 mL/hr of metronidazole.

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.

Correct Answer is ["15"]

Explanation

To answer this question, we need to calculate the dose of esmolol in mcg/kg/min, then convert it to mg/hr, and then use the formula:

mL/hr = (dose in mg/hr) x (volume in mL) / (concentration in mg)

First, we convert the client's weight from pounds to kilograms:

110 lb x 1 kg / 2.2 lb = 50 kg

Next, we multiply the client's weight by the prescribed dose to get the dose in mcg/min: 50 kg x 50 mcg/kg/min = 2500 mcg/min

Then, we divide the dose in mcg/min by 1000 to get the dose in mg/min: 2500 mcg/min / 1000 = 2.5 mg/min

Finally, we multiply the dose in mg/min by 60 to get the dose in mg/hr: 2.5 mg/min x 60 = 150 mg/hr

Now, we can use the formula to find the infusion rate in mL/hr:

mL/hr = (150 mg/hr) x (250 mL) / (2500 mg)

mL/hr = 15

Therefore, the nurse should set the IV pump to deliver 15 mL/hr.
