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.)

Answer and Explanation

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 ["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.

Correct Answer is ["1.0"]

Explanation

To calculate the volume of etanercept to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

Plugging in the given values:

Volume (mL) = 25 mg / 50 mg/mL

Volume (mL) = 0.5 mL

Since the medication is available in a prefilled syringe labeled 50 mg/2 mL, we need to administer 2 mL to obtain the desired dose of 25 mg.

Therefore, the nurse should administer 1.0 mL of etanercept.
