Question 17 :
Penicillin G procaine 240,000 units Intramuscularly is prescribed for a 4-year-old child who has a streptococcal respiratory Infection. The medication vial is labeled 1,200,000 units/2 mL. How many ml. should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: ["0.4 mL"]
The nurse should administer 0.4 mL of the medication. This is because 240,000 units is the desired dose, and 1,200,000 units/2 mL is the concentration of the medication. To find the concentration in units per mL, we divide by 2, so it is 600,000 units/mL. Using the same formula as before, we can solve for V by plugging in the values: V = 240,000/600,000 = 0.4.
