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 ["4.7"]
Explanation
The healthcare provider prescribes ampicillin 140 mg intravenously (IV) every 8 hours for a child with meningitis.
The vial is labeled "ampicillin 250 mg for intravenous (IV) use" and requires reconstitution with 83 mL of sterile normal saline for injection to yield a total solution concentration of 30 mg/mL.
This means that for every mL of the solution, there is 30 mg of ampicillin.
To administer a dose of 140 mg, the nurse should give the child 4.7 mL of the solution (140 mg ÷ 30 mg/mL = 4.7 mL).
Correct Answer is ["8"]
Explanation
The total daily dose is 80 mg (20 mg x 4). Since the medication is available in 10 mg tablets, we can calculate the number of tablets required as follows:
80 mg / 10 mg per tablet = 8 tablets
