A nurse is preparing to administer ceftriaxone 400 mg IM to an infant in two divided doses. Available is ceftriaxone injection 500 mg/2 mL. How many total mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.6"]
Step 1: Determine the total dose of ceftriaxone to administer.
The total dose prescribed is 400 mg. This dose will be divided into two equal doses for the infant.
Step 2: Calculate the volume for each dose.
The available ceftriaxone solution has a concentration of 500 mg in 2 mL. This means that 500 mg is present in 2 mL, so each mL contains 250 mg of ceftriaxone.
To calculate how many mL are needed for the total dose of 400 mg, we use the following formula:
Volume (mL)=Dose in mg/Concentration in mg/mL=400 mg/250 mg/mL=1.6 mL
Step 3: Round the answer.
1.6 mL

Correct Answer is ["400"]
Explanation
Step by step calculation:
The nurse needs to administer 100 mL of sodium chloride.
The infusion time is 15 minutes.
Calculating the flow rate in mL/hr:
Convert the infusion time to hours: 15 minutes ÷ 60 minutes/hour = 0.25 hours
Divide the total volume by the infusion time: 100 mL ÷ 0.25 hours = 400 mL/hour
Correct Answer is ["1.5"]
Explanation
Step-by-step calculation:
The desired dose of ibuprofen is 150 mg.
The available medication concentration is 100 mg/5 mL.
We need to convert mL to tsp.
Calculating the volume to administer in mL:
Use the concentration of the medication: 150 mg ÷ (100 mg/5 mL) = 150 mg ÷ 20 mg/mL = 7.5 mL
Converting mL to tsp:
1 tsp = 5 mL
7.5 mL ÷ 5 mL/tsp = 1.5 tsp
