A nurse is preparing to administer chlorpromazine 0.55 mg/kg IM to a child who weighs 66 lb. Available is chlorpromazine 25 mg/ml. for injection. 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 ["0.7"]

To calculate the dose of chlorpromazine for a child who weighs 66 lb, first convert the weight to kilograms by dividing by 2.2.

This gives 66 / 2.2 = 30 kg.

Then multiply the weight by the prescribed dose of 0.55 mg/kg to get the total dose in milligrams: 30 x 0.55 = 16.5 mg.

Finally, divide the total dose by the concentration of the injection solution to get the volume in milliliters: 16.5 / 25 = 0.66 ml.

The nurse should administer 0.7 ml of chlorpromazine IM to the child.

Correct Answer is ["0.5"]

Explanation

To calculate the correct dosage of promethazine for a client, the nurse needs to use the formula D/H x V, where D is the desired dose, H is the available dose, and V is the available volume. In this case, D is 25 mg, H is 50 mg, and V is 1 mL.

Plugging these values into the formula, we get:

25/50 x 1 = 0.5 mL

Therefore, the nurse should administer 0.5 mL of promethazine 50 mg/mL IM to the client.

Correct Answer is ["2"]

Explanation

To give a loading dose of ketorolac 30 mg IM, the nurse needs to calculate the volume of the injection solution.

The solution has a concentration of 15 mg/mL, which means that every 1 mL contains 15 mg of ketorolac.

To find the volume, the nurse can use the formula: volume = dose / concentration. Plugging in the values, we get: volume = 30 mg / 15 mg/mL = 2 mL.

Therefore, the nurse should administer 2 mL of ketorolac injection for a loading dose.
