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

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
