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

Therefore, 4 tbsp x 15 mL/tbsp = 60 mL
The nurse should administer 60 mL of ibuprofen.
Correct Answer is ["0.5"]
