A nurse is preparing to administer vancomycin 1 g in 250 ml 0.9% sodium chloride by intermittent IV bolus over 90 min. 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 ["167"]

To calculate the infusion rate for the IV pump, we need to divide the total volume of the  solution (250 mL) by the infusion time (90 min). This gives us: 

250 mL / 90 min = 2.778 mL/min

To convert this to mL/hr, we need to multiply by 60 min/hr. This gives us: 2.778 mL/min x 60 min/hr = 166.667 mL/hr 

To round this to the nearest whole number, we look at the tenths place and see that it is 6,  which is equal to or greater than 5, so we round up and drop the rest of the digits. This  gives us: 

167 mL/hr 

Therefore, the nurse should set the IV pump to deliver 167 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 ["1.9"]

Explanation

To calculate the dose of dexamethasone, we need to convert the client's weight from pounds to kilograms. One pound is equal to 0.454 kg, so 132 lb is equal to 132 x 0.454 = 59.928 kg. The prescribed dose is 0.5 mg/kg/day, so the daily dose is 0.5 x 59.928 = 29.964 mg. This dose is divided equally every 6 hours, so the dose per administration is 29.964 / 4 = 7.491 mg. The concentration of the drug is 4 mg/mL, so the volume per administration is 7.491 / 4 = 1.873 mL. Rounded to the nearest tenth, the nurse should administer 1.9 mL per dose.
