A nurse is preparing to administer 250mg of antibiotic IM. Available is 6g/10mL. How many mL should the nurse administer per dose? Round of to the nearest tenth. Use a leading zero if it applies if it applies. Do not use a trailing zero.
The Correct Answer is ["0.4"]
To determine the correct volume to administer, follow these steps:
1. Convert the available concentration to mg/mL:
6 grams = 6000 mg (since 1 gram = 1000 mg)
Therefore, 6000 mg / 10 mL = 600 mg/mL.
2. Calculate the volume to administer:
The ordered dose is 250 mg.
Volume to administer = 250 mg / 600 mg/mL = 0.4167 mL.
3. Round to the nearest tenth:
0.4167 mL rounded to the nearest tenth is 0.4 mL.

Correct Answer is ["538"]
Explanation
1. Convert pounds to kilograms: 1 pound = 0.453592
158 lbs x 0.453592 kg/lb ≈ 71.71 kg
2. Calculate the total daily dosage:
15 mg/kg/day x 71.71 kg ≈ 1075.65 mg/day
3. Calculate the dosage per dose (divided equally every 12 hours):
1075.65 mg/day / 2 doses ≈ 537.83 mg/dose
4. Round to the nearest whole number:
537.83 mg ≈ 538 mg
Correct Answer is ["260"]
Explanation
Here's how we calculated that:
Juice: 1/2 cup = 120 mL
Gelatine: 3 oz = 90 mL
Ice pop: 1 oz = 30 mL
Total: 120 mL + 90 mL + 30 mL + 20 mL = 260
