A nurse is caring for a client who has a new prescription for sotalol 320 mg/day in two divided doses. The amount available is 80 mg tablets. How many tablets should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

To determine how many tablets of sotalol the nurse should administer with each dose, you can use the following calculation:

Total daily dose / Number of doses per day = Dose per administration

In this case, the total daily dose is 320 mg, and it's divided into two doses per day.

320 mg / 2 doses = 160 mg per administration

Now, you know that the nurse should administer 160 mg of sotalol with each dose. The available tablets are 80 mg each, so you can calculate how many tablets are needed:

Dose per administration / Tablet strength = Number of tablets

160 mg / 80 mg/tablet = 2 tablets

Therefore, the nurse should administer 2 tablets of sotalol with each dose.

Correct Answer is ["1.2"]

Explanation

To calculate the mL of phenobarbital to administer per dose, you can use the following steps:

Convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram.
Weight in kg = 165 lb / 2.2 lb/kg ≈ 75 kg

Calculate the total daily dose based on the client's weight and the prescribed dose per kilogram:
Total daily dose = 2 mg/kg/day × 75 kg ≈ 150 mg/day

Since the dose is divided into two equal doses per day, calculate the dose per dose:
Dose per dose = Total daily dose / 2 = 150 mg / 2 = 75 mg

Now, you need to find out how many mL of phenobarbital 65 mg/mL corresponds to a dose of 75 mg:
Volume (mL) = Dose (mg) / Concentration (mg/mL) = 75 mg / 65 mg/mL ≈ 1.1538 mL

Rounded to the nearest tenth, the nurse should administer approximately 1.2 mL of phenobarbital per dose.

Correct Answer is ["2.4"]

Explanation

To calculate the amount of calcitonin the nurse should administer, follow these steps:

Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2 Weight in kilograms = 130 lb / 2.2 = 59.09 kg (rounded to two decimal places)

Calculate the total units of calcitonin needed: Total units = Weight in kilograms × Dose per kilogram Total units = 59.09 kg × 8 units/kg = 472.72 units

Determine the volume (ml) to administer using the concentration of the available calcitonin: Volume (ml) = Total units needed / Concentration (units/ml) Volume (ml) = 472.72 units / 200 units/ml = 2.36 ml

Rounded to the nearest tenth of a milliliter, the nurse should administer 2.4 ml of calcitonin.
