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 ["2"]

Explanation

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

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

Plugging in the given values:

Volume (mL) = 10 mg / 5 mg/mL

Volume (mL) = 2 mL

Now, we need to convert milliliters to teaspoons.

1 teaspoon ≈ 4.93 mL

To find the number of teaspoons needed:

Number of teaspoons = Volume (mL) / Volume per teaspoon (mL/teaspoon)

Number of teaspoons = 2 mL / 4.93 mL/teaspoon

Number of teaspoons ≈ 0.406 teaspoons

Since we cannot administer a fraction of a teaspoon, we round up to the nearest whole number.

Therefore, the nurse should administer 2 teaspoons of metoclopramide

Correct Answer is ["2"]

Explanation

To calculate the number of additional tablets needed, we'll first determine the total number of tablets required for the new dose of 20 mg.

Step 1: Calculate the total number of tablets needed for the new dose:

Total Tablets = Desired Dose (mg) / Tablet Strength (mg)

Total Tablets = 20 mg / 5 mg/tablet

Total Tablets = 4 tablets

Step 2: Determine the number of tablets already administered:

The nurse administered 10 mg, which is equivalent to 2 tablets (since each tablet is 5 mg).

Step 3: Calculate the number of additional tablets needed:

Additional Tablets = Total Tablets - Tablets Already Administered

Additional Tablets = 4 tablets - 2 tablets

Additional Tablets = 2 tablets

Therefore, the nurse should administer 2 additional tablets of benazapril to reach the new prescribed dose of 20 mg.
