Question 1:
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)
Explanation
Correct Answer: 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.

Question 2:
A nurse is preparing to administer tobramycin 3 mg/kg/day IM divided in three
equal doses to a client who weighs 50 kg. Available is tobramycin 40 mg/mL
How many mL should the nurse administer per dose? (Round the answer to the
nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 1.3
Step-by-step solution:
1. Calculate the total daily dose:
Total daily dose = dose per kg/day x weight in kg = 3 mg/kg/day x 50 kg = 150 mg/day
2. Calculate the dose per administration:
Since the medication is divided into 3 doses per day,
Dose per administration = Total daily dose / number of doses = 150 mg/day / 3 doses
= 50 mg/dose
3. Calculate the volume to administer:
The medication concentration is 40 mg/mL.
Volume = Dose per administration / Concentration = 50 mg / 40 mg/mL = 1.25 mL
4. Round to the nearest tenth:
Volume = 1.3 mL
Therefore, the nurse should administer 1.3 mL of tobramycin per dose

Question 3:
A nurse is calculating the total fluid intake for a client on strict 180; during your
shift the client had 12 oz of orange juice, 12 oz of ice chips, 6 oz of coffee with 4
oz of skim milk, 24 oz of water, and 1000 mL of IV fluid infusion. What was the
client's total intake for your shift?
Explanation
Correct Answer: 2740
Understanding the problem
We need to calculate the total fluid intake in mL.
We have various fluids in different units (oz and mL).
Step-by-step calculation
Convert ounces to milliliters:
1 oz = 30 mL
Orange juice: 12 oz x 30 mL/oz = 360 mL
Ice chips: 12 oz x 30 mL/oz = 360 mL
Coffee: 6 oz x 30 mL/oz = 180 mL
Skim milk: 4 oz x 30 mL/oz = 120 mL
Water: 24 oz x 30 mL/oz = 720 mL
