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.)
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 ["30"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL/hr = (mcg/kg/min x kg x 60 min) / (mg/mL x 1000 mcg/mg)
The client's weight in kilograms is:
110 lb / 2.2 lb/kg = 50 kg
The concentration of dobutamine in mg/mL is:
250 mg / 250 mL = 1 mg/mL
Plugging these values into the formula, we get:
mL/hr = (10 mcg/kg/min x 50 kg x 60 min) / (1 mg/mL x 1000 mcg/mg) mL/hr = (30,000 mcg/min) / (1000 mcg/mg)
mL/hr = 30 mg/min
mL/hr = 30 mL/hr
Therefore, the nurse should set the IV pump to deliver 30 mL/hr.
Correct Answer is B
Explanation
A. The medication is for IV administration: This cannot be assumed unless the label specifically states “for intravenous use.” Phenytoin comes in multiple formulations (oral suspension, tablets, IV), so route must be verified.
B. The total amount available per container is 4 mL: This is label-specific information. If the label indicates that each vial contains 4 mL, this is a factual and critical point to ensure accurate dosing.
C. The nurse should avoid shaking the medication: While some medications (e.g., suspensions) should not be shaken vigorously, phenytoin IV solution is not a suspension, and this instruction may not apply to all forms.
D. The medication should not be stored below 30°C (86°F): This is incorrect. Phenytoin should be stored at controlled room temperature, typically 20°C to 25°C (68°F to 77°F), and protected from excessive heat or cold.
