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 number of tablets needed to administer promethazine 25 mg PO, the nurse should use the following formula:

(number of tablets) = (desired dose) / (available dose)

Substituting the values given in the question, we get:

(number of tablets) = (25 mg) / (12.5 mg)

Simplifying, we get:

(number of tablets) = 2

Therefore, the nurse should administer 2 tablets of promethazine 12.5 mg to the client.

Correct Answer is ["0.25"]

Explanation

To calculate the dosage of interferon beta-1a for the client, the nurse should use the following formula:

Dose (mL) = Desired dose (mcg) / Available dose (mcg/mL)

Plugging in the values from the prescription and the medication label, we get:

Dose (mL) = 11 mcg / 22 mcg/0.5 mL

Simplifying the fraction, we get:

Dose (mL) = 0.5 / 2

Dividing both sides by 2, we get:

Dose (mL) = 0.25

Therefore, the nurse should administer 0.25 mL of interferon beta-1a per dose.
