Question

You have a syringe containing 300 mg of drug in 50 mL. The rate is 2 mL per hour. How many mg/hr is your patient receiving?

Answer 1

To calculate the rate at which the patient is receiving the drug in mg/hr, we'll follow these steps:

Step 1: Find out how much of the drug is in 1 mL of the solution. Step 2: Calculate how many mg of the drug are delivered in 1 hour (2 mL/hr). Step 3: Determine the mg/hr for the entire syringe (50 mL).

Let's calculate it step by step:

Step 1: Amount of drug in 1 mL of the solution 300 mg / 50 mL = 6 mg/mL

Step 2: Amount of drug delivered in 1 hour (2 mL/hr) 2 mL/hr * 6 mg/mL = 12 mg/hr

Step 3: Total mg/hr for the entire syringe (50 mL) Since the rate is 2 mL/hr, we can multiply the amount delivered in 1 hour by the rate: 12 mg/hr * 2 = 24 mg/hr

Therefore, the patient is receiving 24 mg of the drug per hour.
