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 50 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.) _mL/hr
The Correct Answer is ["100"]
We are given the following information:
Medication: Ticarcillin/clavulanate 3.1 g
Administration route: Intermittent IV bolus over 30 minutes
Available solution: Ticarcillin/clavulanate 3.1 g in 50 mL 0.9% sodium chloride (NSS)
However, the IV pump controls the rate of delivery over time (usually in hours). An intermittent bolus means the medication is infused all at once over a shorter period (30 minutes in this case).
The pump rate calculation here focuses on the total volume of the available solution containing the medication to be delivered, not necessarily on the medication amount itself.
Therefore, we need to find the rate at which the total volume of 50 mL solution should be delivered over 30 minutes.
Conversion is necessary because pump rates are typically set in hours (hr).
Time (hours) = 30 minutes / 60 minutes/hour = 0.5 hours
Now, calculate the flow rate:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours)
Flow rate (mL/hr) = 50 mL / 0.5 hours = 100 mL/hr
Round to the nearest whole number as requested.
Therefore, the nurse should set the pump to deliver approximately 100 mL/hr. This ensures the total 50 mL solution containing the 3.1 g of ticarcillin/clavulanate is delivered over the intended 30-minute period.

Correct Answer is ["2"]
Explanation
Here's how to find the volume the nurse should administer:
Medication dose to be administered: 250 mg
Available medication concentration: 1000 mg/8 mL
We need to find the volume (in mL) that contains the desired dose (250 mg) of hydrocortisone sodium succinate.
Set up a proportion:
Desired dose (mg) : Volume to administer (mL) = Concentration (mg/mL) : Available volume (mL)
In this case:
Desired dose (mg) = 250 mg
Concentration (mg/mL) = 1000 mg/8 mL (available concentration)
Volume to administer (mL) = Unknown (what we need to find)
Available volume (mL) = 8 mL (volume of solution containing the concentrated medication)
Solve for the volume to administer (mL):
Volume to administer (mL) = (Desired dose (mg) x Available volume (mL)) / Concentration (mg/mL)
Volume to administer (mL) = (250 mg x 8 mL) / 1000 mg/mL
Calculate the volume:
Volume to administer (mL) = 2000 mg / 1000 mg/mL
Volume to administer (mL) = 2 mL (round to nearest whole number as requested)
Therefore, the nurse should administer approximately 2 mL of the hydrocortisone sodium succinate solution.
Correct Answer is ["43.1"]
Explanation
Here's how we can find the dose:
Convert client weight to kilograms (kg):
We know 1 kg = 2.205 pounds.
Client weight (kg) = 95 lbs / 2.205 lb/kg = 43.1 kg (round to one decimal place for accuracy in calculation).
Calculate the enoxaparin dosage per dose:
Prescribed dosage: 1 mg/kg/dose
Client weight (kg): 43.1 kg (rounded value from step 1)
Enoxaparin dose per dose (mg) = Dosage (mg/kg/dose) x Client weight (kg)
Enoxaparin dose per dose (mg) = 1 mg/kg/dose * 43.1 kg = 43.1 mg (round to nearest tenth as requested)
Therefore, the nurse should administer approximately 43.1 mg of enoxaparin per dose.
