A client received a prescription for dexamethasone 3 mg/day PO every 8 hours. The medication is available in 1.5 mg/tablet. How many tablets should the nurse administer with each dose?

Answer and Explanation

The Correct Answer is ["2"]

To calculate the number of tablets needed, we can set up a proportion:

x tablets / 3 mg = 1 tablet / 1.5 mg

Cross-multiplying:

1.5x = 3

Solving for x:

x = 3 / 1.5

x = 2

Therefore, the nurse should administer 2 tablets of dexamethasone for each dose.

Explanation

Calculating the Dobutamine Infusion Rate

Step 1: Convert grams to milligrams:

0.5 grams = 500 mg

Step 2: Calculate the concentration of dobutamine in the IV solution:

500 mg / 250 mL = 2 mg/mL

Step 3: Convert micro-grams to milligrams:

1200 mcg x (1 mg / 1000 mcg) = 1.2 mg

Step 4: Set up a proportion:

We want to find the infusion rate in mL/minute.

We know the desired dose rate (1.2 mg/minute) and the concentration of the medication (2 mg/mL).

Proportion:

x mL/minute / 1.2 mg/minute = 1 mL / 2 mg

Step 5: Cross-multiply and solve for x:

2x = 1.2

x = 0.6 mL/minute

Step 6: Convert mL/minute to mL/hour:

0.6 mL/minute x 60 minutes/hour = 36 mL/hour

Therefore, the nurse should program the infusion pump to deliver 36 mL/hour.

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.
