A nurse is preparing to administer lorazepam 50 mcg/kg IM to a client who weighs 176 lb. Available is lorazepam 4 mg/mL. How many mL should the nurse administer? (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 ["1"]

This is a question that tests the nurse's ability to calculate drug dosages based on the client's weight and the drug concentration. To solve this problem, the nurse needs to follow these steps:

1. Convert the client's weight from pounds to kilograms by dividing by 2.2. 176 lb / 2.2 = 80 kg.

2. Multiply the client's weight in kilograms by the prescribed dose in micrograms per kilogram to get the total dose in micrograms. 80 kg x 50 mcg/kg = 4000 mcg.

3. Convert the total dose in micrograms to milligrams by dividing by 1000. 4000 mcg / 1000 = 4 mg.

4. Divide the total dose in milligrams by the drug concentration in milligrams per milliliter to get the volume in milliliters. 4 mg / 4 mg/mL = 1 mL.

5. Round the answer to the nearest whole number and add a leading zero if it applies. Do not use a trailing zero. The final answer is 1 mL.

Therefore, the nurse should administer 1 mL of lorazepam IM to the client.

Correct Answer is ["2"]

Explanation

To calculate the dosage of diazepam, the nurse needs to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity.

In this case, D is 10 mg, H is 5 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

10 mg / 5 mg/mL x 1 mL = 2 mL

Therefore, the nurse should administer 2 mL of diazepam injection to the client.

Correct Answer is ["1.9"]

Explanation

To calculate the dosage of isoniazid injection, the nurse should use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity.

In this case, D is 187 mg, H is 100 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

187 mg / 100 mg/mL x 1 mL = 1.87 mL

To round the answer to the nearest tenth, the final answer is: 1.9 mL

The nurse should administer 1.9 mL of isoniazid injection to the patient.
