A nurse is preparing to administer ticarcillin / clavulanate 3.1 g by intermittent IV bolus over 30 min. Available is ticarcillin clavulanate 3.1 g in 150 ml 0.9% sodium chloride (NSS). 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 ["300"]
Understanding the problem
We need to administer 150 mL of the medication over 30 minutes.
We need to determine the flow rate in mL/hr.
Step-by-step calculation
Convert minutes to hours:
30 minutes = 0.5 hours
Calculate the flow rate:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours) = 150 mL / 0.5 hours = 300 mL/hr
Therefore, the nurse should set the IV pump to deliver 300 mL/hr.

Correct Answer is ["24"]
Explanation
Calculations:
The heparin solution contains 25,000 units in 500 mL.
To deliver 1,200 units/hour, we need to find out how many mL will deliver this amount.
Set up a proportion:
25,000 units / 500 mL = 1,200 units / x mL
Cross-multiply:
25,000x = 1,200 x 500
Solve for x:
x = (1,200 x 500) / 25,000 = 24 mL/hr
The nurse should set the IV pump to deliver 24 mL/hr.
Correct Answer is ["1.2"]
Explanation
Step-by-step solution:
1. Convert pounds to kilograms:
1 lb = 0.453592 kg
33 lb x 0.453592 kg/lb = 14.97 kg
2. Calculate the total daily dose of digoxin:
Total daily dose = dose per kg/day x weight in kg = 8 mcg/kg/day x 14.97 kg = 119.76 mcg/day
3. Calculate the dose per administration:
Since the medication is divided into 2 doses per day,
Dose per administration = Total daily dose / number of doses = 119.76 mcg/day / 2 doses = 59.88 mcg/dose
4. Convert mcg to mg:
1 mg = 1000 mcg
59.88 mcg = 0.05988 mg
5. Calculate the volume to administer:
The medication concentration is 0.05 mg/mL.
Volume = Dose per administration / Concentration = 0.05988 mg / 0.05 mg/mL = 1.1976 mL
6. Round to the nearest tenth:
Volume = 1.2 mL
Therefore, the nurse should administer 1.2 mL of digoxin per dose.
