The health care provider prescribes streptomycin 300 mg IM q12 hours for a client with tuberculosis. The available vial is labeled "Streptomycin 1 gram/2.5 mL." How many milliliters should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)

To calculate the number of milliliters the nurse should administer, we can use the following formula: Dose to administer = Ordered dose / Available dose In this case, the ordered dose is 300 mg and the available dose is 1 g/2.5 mL. We can calculate the dose to administer as follows: 300 mg / 1000 mg/2.5 mL = 0.75 mL. Rounded off: 0.8mL
