Final answer:
To find the answer, we need to calculate the amount of Rocephin needed for a 35lb child and the amount of water to reconstitute it with. The recommended Rocephin dosage for a 35lb child is 795.5 mg, and since the available vial is 1 gram, it is enough to cover the required dosage. The child can receive the full vial of Rocephin 50mg/kg IM once without reconstitution.
Step-by-step explanation:
To find the answer, we need to first calculate the amount of Rocephin needed for a 35lb child. Then, we can determine the amount of water to reconstitute it with.
Rocephin dosage is typically 50-75 mg/kg of body weight. We can convert 35 lb to kg by dividing it by 2.2:
35 lb ÷ 2.2 kg/lb = 15.91 kg
So, for a 35lb child, the recommended Rocephin dosage would be:
50 mg/kg × 15.91 kg = 795.5 mg
Since the available vial is 1 gram, which is equal to 1000 mg, it is enough to cover the required dosage. Therefore, the child can receive the full vial of Rocephin 50mg/kg IM once without reconstitution.
