A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three divided doses to a client who weighs 85 kg. The amount available is tobramycin 40 mg/ml. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2.1"]

To calculate the amount of tobramycin to administer per dose, you need to follow these steps:

Step 1: Calculate the total daily dose. Total Daily Dose (mg) = Weight (kg) x Dose (mg/kg/day)

Total Daily Dose (mg) = 85 kg x 3 mg/kg/day = 255 mg/day

Step 2: Calculate the dose per divided dose (three divided doses). Dose per Divided Dose (mg) = Total Daily Dose (mg) / Number of Divided Doses

Dose per Divided Dose (mg) = 255 mg / 3 doses = 85 mg/dose

Step 3: Convert the dose to mL using the concentration. Dose (mL) = Dose (mg) / Concentration (mg/mL)

Dose (mL) = 85 mg / 40 mg/mL ≈ 2.125 mL

Rounded to the nearest tenth, the nurse should administer 2.1 mL per dose.

Correct Answer is ["2"]

Explanation

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 ["2.3"]

Explanation

To calculate the amount of morphine (in mL) the nurse should administer, follow these steps:

Step 1: Convert the client's weight from pounds to kilograms. 99 lb / 2.2 lb/kg ≈ 45 kg (rounded to the nearest whole number)

Step 2: Calculate the total dose based on the client's weight. 0.1 mg/kg * 45 kg = 4.5 mg

Step 3: Determine how many mL of the available morphine solution (2 mg/mL) are needed to achieve the prescribed dose. 4.5 mg ÷ 2 mg/mL = 2.25 mL

Rounded to the nearest tenth, the nurse should administer 2.3 mL of morphine.
