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.)
The Correct Answer is ["0.8"]
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

Correct Answer is ["75"]
Explanation
The healthcare provider prescribes an IV solution of isoproterenol 1 mg in 250 mL of Dextrose in Water (D/W) at a rate of 300 mcg/hour.
Since 1 mg is equivalent to 1000 mcg, the concentration of isoproterenol in the IV solution is 4 mcg/mL (1000 mcg / 250 mL).
Since the healthcare provider prescribes 300 mcg/hour of isoproterenol, the nurse should program the infusion pump to deliver 75 mL/hour of the IV solution (300 mcg/hour / 4 mcg/mL).
Correct Answer is ["0.9"]
Explanation
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 90 mg and the available dose is 100 mg/1 mL. We can calculate the dose to administer as follows:
90 mg / 100 mg/1 mL = 0.9 mL.
