A client receives a prescription for diazepam 12.5 mg IV. The available concentration is 5 mg per ml. How many ml should the nurse administer? (Enter the numerical value only. If rounding is required round to the nearest tenth.)
The Correct Answer is ["2.5"]
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 ["33"]
Explanation
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.

Calculation for 3/4 Strength Ensure Feeding
Prompt: To determine how many milliliters of full-strength Ensure to use to prepare a 3/4 strength feeding.
Given:
Desired volume of 3/4 strength Ensure: 275 mL
Strength required: 3/4
Formula:
Amount of full-strength Ensure = Total volume x Strength required
Calculation:
Amount of full-strength Ensure = 275 mL x (3/4)
Amount of full-strength Ensure = (275 x 3) / 4
Amount of full-strength Ensure = 825 / 4
Amount of full-strength Ensure = 206.25 mL
Rounding to the nearest whole number:
Amount of full-strength Ensure = 206 mL
Therefore, the nurse should use 206 mL of full-strength Ensure to prepare the feeding.
