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.)
The Correct Answer is ["0.5"]
The correct answer is 0.5 mL. To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (200) / (1000 / 2.5)
Simplifying, we get:
(mL to be administered) = (200) x (2.5 / 1000)
(mL to be administered) = 0.5
Therefore, the nurse should administer 0.5 mL of streptomycin from the vial to the client.

Correct Answer is ["10 mL"]
Explanation
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Calculate the volume of amoxicillin suspension in mL by dividing the dose in mg by the concentration in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (88) / (2.2) = 40 kg
- (volume in mL) = (500) / (250 / 5) = 10 mL
- (rounded volume in mL) = 10 mL
Therefore, the nurse should administer 10 mL of amoxicillin suspension to the child.
Correct Answer is ["7 mL"]
Explanation
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Calculate the total daily dose of amoxicillin in mg by multiplying the weight in kg by the dosage in mg/kg/day
- Divide the total daily dose of amoxicillin in mg by the number of doses per day to get the dose per administration
- Divide the dose per administration in mg by the concentration of amoxicillin in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (66) / (2.2) = 30 kg
- (total daily dose in mg) = (80) x (30) = 2400 mg
- (dose per administration in mg) = (2400) / (2) = 1200 mg
- (volume per administration in mL) = (1200) / (400 / 5) = 15 mL
- (rounded volume per administration in mL) = 15 mL
Therefore, the nurse should administer 15 mL of amoxicillin oral suspension with each dose.
