The health-care provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How many tablets should the nurse plan to administer?

1 tablet.

1/2 tablet.

2 tablets.

1 1/2 tablets.

Answer and Explanation

The Correct Answer is C

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

x tablets / 7.5 mg = 1 tablet / 5 mg

Cross-multiplying:

5x = 7.5

Solving for x:

x = 7.5 / 5

x = 1.5

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

Therefore, the nurse should administer 2 tablets of metolazone.

Correct Answer is ["2"]

Explanation

Understanding the Problem:

We need to administer 500 mg of amoxicillin/clavulanate potassium.

The available tablets contain 250 mg amoxicillin and 125 mg clavulanate potassium.

Solution:

Determine the total amount of active ingredients in the available tablets:

250 mg (amoxicillin) + 125 mg (clavulanate potassium) = 375 mg/tablet

Calculate the number of tablets needed:

500 mg (desired dose) / 375 mg/tablet = 1.33 tablets

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

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

A. 1630. B. 0420. C. 1620. D. 0430.

Correct Answer is C

Explanation

To calculate the infusion time, we'll use the following formula:

Infusion Time (hours) = Total Volume (mL) / Infusion Rate (mL/hour)

Plugging in the given values:

Infusion Time = 1000 mL / 75 mL/hour

Calculating the result:

Infusion Time ≈ 13.33 hours

Converting hours to minutes:

0.33 hours x 60 minutes/hour ≈ 20 minutes

Therefore, the infusion will be completed approximately 13 hours and 20 minutes after it started at 0300.

Adding 13 hours and 20 minutes to 0300:

0300 + 13 hours + 20 minutes = 1620

So, the correct answer is C. 1620.
