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 ["5.8"]
Explanation
To calculate the infusion rate, we'll follow these steps:
1. Calculate the desired dose rate in mcg/minute:
Desired Dose Rate = Weight (kg) x Dose (mcg/kg/minute)
Desired Dose Rate = 86 kg x 8 mcg/kg/minute
Desired Dose Rate = 688 mcg/minute
2. Convert micro-grams to milligrams:
688 mcg x (1 mg / 1000 mcg) = 0.688 mg/minute
3. Calculate the concentration of dopamine in the IV solution:
Dopamine Concentration = Dopamine (mg) / Solution Volume (mL)
Dopamine Concentration = 800 mg / 500 mL
Dopamine Concentration = 1.6 mg/mL
4. Set up a proportion:
x mL/hour / 0.688 mg/minute = 60 minutes/hour / 1.6 mg/mL
5. Cross-multiply and solve for x:
x mL/hour = 0.688 mg/minute x 60 minutes/hour / 1.6 mg/mL
x mL/hour ≈ 25.8 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 25.8 mL/hour.
Correct Answer is ["1"]
Explanation
To calculate the number of additional tablets needed, we'll first determine the total number of tablets required for the new dose of 30 mg.
Step 1: Calculate the total number of tablets needed for the new dose:
Total Tablets = Desired Dose (mg) / Tablet Strength (mg)
Total Tablets = 30 mg / 15 mg/tablet
Total Tablets = 2 tablets
Step 2: Determine the number of tablets already administered:
The client already received 1 tablet today.
Step 3: Calculate the number of additional tablets needed:
Additional Tablets = Total Tablets - Tablets Already Administered
Additional Tablets = 2 tablets - 1 tablet
Additional Tablets = 1 tablet
Therefore, the nurse should administer 1 additional tablet of aripiprazole (Abilify) to reach the total newly prescribed dose for the day.
