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.)
The Correct Answer is ["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

Correct Answer is ["4.8"]
Explanation
Understanding the problem
We need to administer 240 mg of hydrocortisone.
The reconstituted solution has a concentration of 50 mg/mL.
We need to determine the volume to administer.
Step-by-step calculation
Use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume (mL) = 240 mg / 50 mg/mL
Calculate the volume:
Volume (mL) = 4.8 mL
Therefore, the nurse should administer 4.8 mL of the reconstituted hydrocortisone solution.
Correct Answer is ["1880"]
Explanation
Understanding the problem
We need to calculate the total fluid intake in mL.
We have various fluids in ounces and mL.
There is a continuous IV infusion at 50 mL/hr for 12 hours.
Step-by-step calculation
Convert ounces to milliliters:
1 oz = 30 mL
Orange juice (½ cup):
½ cup = 4 oz → 4 oz = 120 mL
Milk:
8 oz = 240 mL
Coffee:
6 oz x 30 mL/oz = 180 mL
Ice chips:
4 oz x 1/2 x 30 mL/oz = 60 mL
Gelatin:
6 oz x 30 mL/oz = 180 mL
Decaffeinated coffee:
6 oz x 30 mL/oz = 180 mL
Apple juice:
4 oz x 30 mL/oz = 120 mL
Water: 200 mL
Calculate total oral fluid intake:
Calculate IV fluid intake:
IV fluid intake = 50 mL/hr x 12 hours = 600 mL
Calculate total fluid intake:
Therefore, the client's total fluid intake for the 12-hour shift is 1880 mL.
