A nurse is preparing to administer 750,000 units of procaine penicillin GIM. Available is procaine penicillin G injection 600,000 units/ml. How many m should the nurse administer? (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"]
Desired dose = 750,000 units
Available concentration = 600,000 units/mL
Volume to administer = Desired dose / Concentration = 750,000 units / 600,000 units/mL = 1.25 mL
Rounded to the nearest tenth = 1.3 mL

Correct Answer is ["2560"]
Explanation
- Convert ounces to milliliters (mL):
-
1 ounce (oz) is approximately equal to 30 mL.
-
Orange juice: 12 oz * 30 mL/oz = 360 mL
-
Ice chips: 12 oz * 30 mL/oz = 360 mL (Note: Ice melts to about half its volume, so we'll divide this by 2 later)
-
Coffee: 6 oz * 30 mL/oz = 180 mL
-
Skim milk: 4 oz * 30 mL/oz = 120 mL
-
Water: 24 oz * 30 mL/oz = 720 mL
- Account for ice chips melting:
- Ice chips: 360 mL / 2 = 180 mL
- Add up all the fluid intake in mL:
- Orange juice: 360 mL
- Ice chips: 180 mL
- Coffee: 180 mL
- Skim milk: 120 mL
- Water: 720 mL
- IV fluid: 1000 mL
Total: 360 + 180 + 180 + 120 + 720 + 1000 = 2560 mL
Correct Answer is ["0.5"]
Explanation
Calculation:
Desired dose = 50 mg
Concentration = 100 mg/mL
Volume = Desired dose / Concentration = 50 mg / 100 mg/mL = 0.5 Ml
