An IV infusion of 0.9% normal saline 500 ml with ammonium chloride 0.2 mEq/ml is prescribed for a client who was admitted for an amphetamine overdose. How many mEq of ammonium chloride should the nurse use to prepare the solution? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["100"]
To calculate the amount of ammonium chloride needed, we can use the following formula:
Amount of Ammonium Chloride (mEq) = Concentration (mEq/mL) x Volume (mL)
Plugging in the given values:
Amount of Ammonium Chloride = 0.2 mEq/mL x 500 mL
Amount of Ammonium Chloride = 100 mEq
Therefore, the nurse should use 100 mEq of ammonium chloride to prepare the solution.

Correct Answer is ["160"]
Explanation
To prepare a 4-hour solution of Osmolite® 1/2 strength enteral formula at 80 ml/hour, the nurse will need to dilute the full-strength formula with a certain amount of water.
Step 1: Calculate the total volume of the 1/2 strength formula needed for 4 hours:
Total Volume = Infusion Rate (mL/hour) x Infusion Time (hours)
Total Volume = 80 mL/hour x 4 hours
Total Volume = 320 mL
Step 2: Determine the volume of full-strength Osmolite® needed:
Since the desired solution is 1/2 strength, we need to dilute the full-strength formula by half.
Volume of Full-Strength Osmolite® = Total Volume / 2
Volume of Full-Strength Osmolite® = 320 mL / 2
Volume of Full-Strength Osmolite® = 160 mL
Step 3: Calculate the volume of water needed to dilute the full-strength Osmolite®:
Volume of Water = Total Volume - Volume of Full-Strength Osmolite®
Volume of Water = 320 mL - 160 mL
Volume of Water = 160 mL
Therefore, the nurse should dilute the full-strength Osmolite® with 160 mL of water to prepare a 4-hour solution.
Correct Answer is ["200"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
First, convert minutes to hours:
75 minutes x (1 hour / 60 minutes) = 1.25 hours
Then, plug in the values into the formula:
Infusion Rate = 250 mL / 1.25 hours
Calculating the result:
Infusion Rate ≈ 200 mL/hour
Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.
