The doctor ordered antibiotic G 5mg/kg/day in three divided doses. The medication is supplied 100mg/mL. The patients weighs 120kg. What volume will 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 ["2.0"]
To determine the correct volume to administer per dose, follow these steps:
1. Calculate the total daily dosage:
The dosage is 5 mg/kg/day.
The patient weighs 120 kg.
Total daily dosage = 5 mg/kg x 120 kg = 600 mg/day.
2. Divide the total daily dosage by the number of doses per day:
The medication is to be given in three divided doses.
Dosage per dose = 600 mg/day / 3 = 200 mg per dose.
3. Determine the volume to administer per dose:
The medication is supplied as 100 mg/mL.
Volume per dose = 200 mg / 100 mg/mL = 2.0 mL.
4. Round to the nearest tenth:
2.0 mL is already rounded to the nearest tenth.

Correct Answer is ["2525"]
Explanation
Here's the calculation of the total intake:
IV fluids:
Lactated Ringer's IV: 150 ml/hr x 9 hrs = 1350 ml
Cefazolin: 100 ml
0.9% sodium chloride (2 units): 250 ml x 2 = 500 ml
Ranitidine: 50 ml
Packed RBCs:
275 ml + 250 ml = 525 ml
Total intake:
1350 ml + 100 ml + 500 ml + 50 ml + 525 ml = 2525 ml
Correct Answer is ["18"]
Explanation
To determine the correct IV pump rate for the heparin infusion, follow these steps:
1. Convert the patient’s weight from pounds to kilograms:
1 pound = 0.453592 kilograms
220 pounds x 0.453592 = 99.79 kilograms (rounded to two decimal places)
2. Calculate the dosage in units per hour:
18 units/kg/hr x 99.79 kg = 1796.22 units/hr
3. Determine the volume of heparin solution needed per hour:
The medication is supplied as 25000 units in 250 mL.
Therefore, the concentration is 100 units/mL.
1796.22 units/hr / 100 units/mL = 17.96 mL/hr
4. So, the nurse should set the IV pump to 18 mL/hour (rounded to the nearest whole number).
