Question 11 :
The healthcare provider prescribes streptomycin 200 mg intramuscularly every 12 hours. The vial is labeled, "Streptomycin 1 gram/2.5 mL. How many milliliters should the nurse administer? (Enter numerical value only. (If rounding is required, round to the nearest tenth.)
Correct Answer: ["0.5 mL"]
To find out how many milliliters of streptomycin to administer, you need to use the formula: D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity on hand, and X is the amount to give. In this case, D = 200 mg, H = 1000 mg, Q = 2.5 mL, and X is unknown. Plug in the values and solve for X:
X = (200 mg / 1000 mg) x 2.5 mL
X = 0.5 mL
Therefore, the nurse should administer 0.5 mL of streptomycin.
