A nurse is preparing to administer morphine 0.1 mg/kg IM to a client who weighs 99 lb. Available is morphine 2 mg/mL. How many ml. should the nurse administer? (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 ["2.3"]

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.

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 ["3"]

Explanation

To calculate how many tablets of pyrazinamide the nurse should administer, you can use the following steps:

Convert the client's weight from pounds (lb) to kilograms (kg):
Client's weight in kg = Client's weight in lb / 2.2 Client's weight in kg = 165 lb / 2.2 ≈ 75 kg

Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 75 kg × 20 mg/kg = 1500 mg

Determine the number of tablets needed:
Number of tablets = Total dosage / Tablet strength Number of tablets = 1500 mg / 500 mg/tablet = 3 tablets

The nurse should administer 3 tablets of pyrazinamide
