A client is receiving an IV solution of 2 grams of medication diluted in 100 ml of normal saline over a one hour time period. How many mg of medication is the client receiving per minute? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["33"]
Step 1: Calculate the concentration of the medication:
Concentration (mg/mL) = Total Medication (mg) / Total Volume (mL)
Concentration = 2000 mg / 100 mL
Concentration = 20 mg/mL
Step 2: Calculate the infusion rate in mg/minute:
Infusion Rate (mg/minute) = Infusion Rate (mL/hour) x Concentration (mg/mL) x (1 hour / 60 minutes)
Infusion Rate = 100 mL/hour x 20 mg/mL x (1 hour / 60 minutes)
Infusion Rate = 33.33 mg/minute
Rounding to the nearest whole number, the client is receiving 33 mg of medication per minute.

Correct Answer is ["2.5"]
Explanation
To calculate the volume of diazepam to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 12.5 mg / 5 mg/mL
Calculating the result:
Volume (mL) = 2.5 mL
Therefore, the nurse should administer 2.5 mL of diazepam.
Correct Answer is C
Explanation
To calculate the infusion time, we'll use the following formula:
Infusion Time (hours) = Total Volume (mL) / Infusion Rate (mL/hour)
Plugging in the given values:
Infusion Time = 1000 mL / 75 mL/hour
Calculating the result:
Infusion Time ≈ 13.33 hours
Converting hours to minutes:
0.33 hours x 60 minutes/hour ≈ 20 minutes
Therefore, the infusion will be completed approximately 13 hours and 20 minutes after it started at 0300.
Adding 13 hours and 20 minutes to 0300:
0300 + 13 hours + 20 minutes = 1620
So, the correct answer is C. 1620.
